I am unable to send data from my client app to a web method, i dont actually know what i am doing wrong any help would be appreciate.
Client:
public void syncClient(Customer c)
{
try
{
var datos = new JavaScriptSerializer().Serialize(c);
DataContractJsonSerializer ser =
new DataContractJsonSerializer(typeof(string));
MemoryStream mem = new MemoryStream();
ser.WriteObject(mem, datos);
string data = Encoding.UTF8.GetString(mem.ToArray(), 0, (int)mem.Length);
string url = store.ParentUrl + "Api/syncClientFromChild";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.ContentType = #"application/json"; //set the content type to JSON
request.Method = "POST";
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
byte[] send = encoding.GetBytes(data);
request.ContentLength = send.Length;
using (Stream newStream = request.GetRequestStream())
{
newStream.Write(send, 0, send.Length);
}
WebResponse ws1 = request.GetResponse();
JavaScriptSerializer serializer = new JavaScriptSerializer();
ApiCtrlResponse response = serializer.Deserialize<ApiCtrlResponse>(serializer.Serialize(ws1.GetResponseStream()));
if (response.success == true)
{
c.Synced = true;
_customerService.UpdateCustomer(c);
}
}
catch (Exception A)
{
}
}
I believe thats fine, but the other method i always get null in the string i need to receive:
[System.Web.Services.WebMethod]
public ActionResult syncClientFromChild(string Customer)
{
// do something
}
What i am missing ? Thanks in advance !
use a Model to accept Http Post,try to not use string,like
public class ReceiveModel
{
string Customer;
}
public ActionResult syncClientFromChild(ReceiveModel model)

I'm trying to post XML from www.domain1.com a controller in www.domain2.com.
Here is my code:
www.domain2.com
[HttpPost]
public ActionResult FetchProductsXML()
{
Response.ContentType = "text/xml";
StreamReader reader = new StreamReader(Request.InputStream);
String xmlData = reader.ReadToEnd();
var products = _productService.SearchProducts(showHidden: false);
var xml = _exportManager.ExportProductsToXml(products);
return this.Content(xml, "text/xml");
}
Then in www.domain1.com I am posting as follows..
private string getProductLIstXML()
{
ASCIIEncoding encoding = new ASCIIEncoding();
string SampleXml = "<testXml>test</testXml>";
try
{
byte[] data = encoding.GetBytes(SampleXml);
string url = "http://www.domain2.com/products-xml";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
byte[] bytes;
bytes = System.Text.Encoding.ASCII.GetBytes(SampleXml);
request.ContentType = "text/xml; encoding='utf-8'";
request.ContentLength = bytes.Length;
request.Method = "POST";
Stream requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
HttpWebResponse response;
response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
{
Stream responseStream = response.GetResponseStream();
string responseStr = new StreamReader(responseStream).ReadToEnd();
return responseStr;
}
return null;
}
catch (WebException webex)
{
return webex.ToString();
}
}
My Custom Route in RouteProvider class
routes.MapLocalizedRoute("FetchProductsXML",
"products-xml",
new { controller = "Product", action = "FetchProductsXML" },
new[] { "Nop.Web.Controllers" });
The error I get is
System.Net.WebException: The remote server returned an error: (404) Not Found.
at System.Net.HttpWebRequest.GetResponse()
I've followed what the examples from the following SOQ's
How to POST XML into MVC Controller? (instead of key/value)
HTTP post XML data in C#
After a long night, I realized I had the method in the incorrect class :(
All fixed now.
I need to send email thanks to php script. Sript in the server, I did post request to the server, and got answer. If all is good I get 0, if I get 1, all is bad.
This is my code:
public class MessagePost
{
public string to { get; set; }
public string from { get; set; }
public string title { get; set; }
public string message { get; set; }
}
[HttpPost]
public ActionResult SendMessage(FEEDBACK feedbackModel)
{
try
{
string FromEmail = feedbackModel.sEmail;
string toEmail = "zicise#mail.ru";
string title = "Сообщение с сайта народный комунальщик от " + feedbackModel.vFIO;
string message = feedbackModel.vMessage;
MessagePost MP = new MessagePost();
MP.to = toEmail;
MP.from = FromEmail;
MP.title = title;
MP.message = message;
List<MessagePost> dataMessage = new List<MessagePost>();
dataMessage.Add(MP);
JavaScriptSerializer serializer = new JavaScriptSerializer();
string json = serializer.Serialize(dataMessage);
// Create a request using a URL that can receive a post.
WebRequest request = WebRequest.Create("http://projects.pushnovn.com/send_email/");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = json;
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();
string convertResult = System.Text.Encoding.UTF8.GetString(byteArray);
RootObject r = JsonConvert.DeserializeObject<RootObject>(responseFromServer);
if (r.code == 0)
{
ViewBag.RedirectMessage = r.msg;
return View("~/Views/Home/RedirectPage.cshtml");
}
else
{
ViewBag.RedirectMessage = r.msg;
return View("~/Views/Home/RedirectPage.cshtml");
}
}
catch (Exception exc)
{
ViewBag.RedirectMessage = "Невозможно отправить e-mail - error: " + exc.Message;
return View("~/Views/Home/RedirectPage.cshtml");
}
}
But I always get 1, what's wrong?
E.g. data
to: zicise#mail.ru
from: test#mail.ru
title: Test Title
message: Test message
Okay.So, I did it.But not good what I want. This is my code for send post query to the server:
public static HttpWebResponse PostMethod(string postedData, string postUrl)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(postUrl);
request.Method = "POST";
request.Credentials = CredentialCache.DefaultCredentials;
UTF8Encoding encoding = new UTF8Encoding();
var bytes = encoding.GetBytes(postedData);
//request.ContentType = "application/javascript";
request.ContentType = "application/x-www-form-urlencoded";
//request.ContentType = "application/json; charset=utf-8";
//request.ContentType = "application/json";
//request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
request.ContentLength = bytes.Length;
using (var newStream = request.GetRequestStream())
{
newStream.Write(bytes, 0, bytes.Length);
newStream.Close();
}
return (HttpWebResponse)request.GetResponse();
}
And ActionResult:
[HttpPost]
public ActionResult SendMessage(FEEDBACK feedbackModel)
{
MessageData msgData = new MessageData();
msgData.to = "zicise#mail.ru";
msgData.from = feedbackModel.sEmail;
msgData.title = "Сообщение с сайта наркома от пользователя: " + feedbackModel.vFIO;
msgData.message = feedbackModel.vFIO;
var jsonString = JsonConvert.SerializeObject(msgData);
var response = PostMethod("to=zicise#mail.ru&from=narkom#info.by&title=Second method&message=test message", "http://projects.pushnovn.com/send_email/");
//var response = PostMethod("to:zicise#mail.ru,from:narkom#info.by,title:Second method,message:test message", "http://projects.pushnovn.com/send_email/");
//var response = PostMethod("{to:zicise#mail.ru,from:narkom#info.by,title:Second method,message:test message}", "http://projects.pushnovn.com/send_email/");
//var response = PostMethod("[{to:zicise#mail.ru,from:narkom#info.by,title:Second method,message:test message}]", "http://projects.pushnovn.com/send_email/");
//var response = PostMethod(jsonString, "http://projects.pushnovn.com/send_email/");
if (response != null)
{
var strreader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
var responseToString = strreader.ReadToEnd();
RootObject r = JsonConvert.DeserializeObject<RootObject>(responseToString);
ViewBag.RedirectMessage = r.msg;
}
return View("~/Views/Home/RedirectPage.cshtml");
}
But this code worked only when I send data in format: to=zicise#mail.ru&from=narkom#info.by&title=Second method&message=test message
But I need to send data from model and get 0 answer. After that PHP script send me email with data. Anyone know, how to convert object in json format name=value&name=value
I want to convert the Object received in the function and do as needed to convert it to an object ({"some_key": "some_value"}).
Here is my code:
public HttpRequests(string url, string method, Object data)
{
//The following prepares data, according to received parameter
if (data is Array)
{
data = (Array)data;
}
else if (data is Dictionary<Object, Object>)
{
data = ((Dictionary<string, string>)data)["something"] = platform_secret;
data = ((Dictionary<string, string>)data)["something2"] = "1";
}
method = method.ToUpper(); //POST or GET
this.url = just_url + url;
this.data = Newtonsoft.Json.JsonConvert.SerializeObject(data);
this.method = method;
}
public Object performRequest()
{
if (this.data != null && url != null)
{
WebRequest request = HttpWebRequest.Create(url);
byte[] data_bytes = Encoding.ASCII.GetBytes(Convert.ToChar(data)[]);
//^ this does not work. Am I supposed to do this?
// as I said, what I want is to get an object {key: something} that can be read
// by $_POST["key"] in the server
request.Method = method;
request.ContentType = "application/x-www-form-urlencoded"; //TODO: check
//request.ContentLength = ((Dictionary<string, string>) data);
request.ContentLength = data_bytes.Length;
Stream dataStream = request.GetRequestStream(); //TODO: not async at the moment
//{BEGIN DOUBT
dataStream.Write(data_bytes, 0, data_bytes.Length);
dataStream.Close();
//DOUBT: DO THIS ^ or THIS:_ ???
StreamWriter writer = new StreamWriter(dataStream);
writer.Write(this.data);
//End DOUBT}
WebResponse response = request.GetResponse();
Stream dataResponse = response.GetResponseStream();
writer.Close();
response.Close();
dataStream.Close();
return dataResponse.
}
What exactly am I missing here?
As you initially assign this.data = Newtonsoft.Json.JsonConvert.SerializeObject(data);, suppose his.data has type string (you can change if it is otherwise).
Then instead of byte[] data_bytes = Encoding.ASCII.GetBytes(Convert.ToChar(data)[]); you need to write just byte[] data_bytes = Encoding.ASCII.GetBytes(data);
After use this
//{BEGIN DOUBT
dataStream.Write(data_bytes, 0, data_bytes.Length);
dataStream.Close();
It will help to do the call with some data but it does not help to solve your problem. request.ContentType = "application/x-www-form-urlencoded"; does not expect that the data is Newtonsoft.Json.JsonConvert.SerializeObject serialized. It expects a string containing & separated pairs that are urlencoded.
name1=value1&name2=value2&name3=value3
So, you need to use this format instead of JSON.
You need to use the first piece of code. Here is and exmaple.
But the second piece could work too, I guess. You have missed nothing on C# side. A problem could be in the data you are going to transfer, however. If it is not correctly encoded, for example.
You should be doing something closer to the lines of this...
void Main()
{
var formSerializer = new FormEncodedSerializer();
formSerializer.Add("key", "value");
formSerializer.Add("foo", "rnd");
formSerializer.Add("bar", "random");
var uri = #"http://example.com";
var contentType = #"application/x-www-form-urlencoded";
var postData = formSerializer.Serialize();
var http = new Http();
Console.WriteLine (http.Post(uri, postData, contentType));
}
public class Http
{
public string Post(string url, string data, string format)
{
var content = Encoding.UTF8.GetBytes(data);
var contentLength = content.Length;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.ServicePoint.Expect100Continue = false;
request.Method = "POST";
request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
request.ContentType = format;
request.ContentLength = contentLength;
using (Stream requestStream = request.GetRequestStream())
{
requestStream.Write(content, 0, content.Length);
}
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
using (Stream responseStream = response.GetResponseStream())
using (StreamReader reader = new StreamReader(responseStream))
{
return reader.ReadToEnd();
}
}
}`
public class FormEncodedSerializer
{
private Dictionary<string, string> formKeysPairs;
public FormEncodedSerializer(): this(new Dictionary<string, string>())
{
}
public FormEncodedSerializer(Dictionary<string, string> kvp)
{
this.formKeysPairs = kvp;
}
public void Add(string key, string value)
{
formKeysPairs.Add(key, value);
}
public string Serialize()
{
return string.Join("", this.formKeysPairs.Select(f => string.Format("&{0}={1}", f.Key,f.Value))).Substring(1);
}
public void Clear()
{
this.formKeysPairs.Clear();
}
}
I did not really understand what your service expects, in which format you have to send the data.
Anyway, if you set ContentType like "application/x-www-form-urlencoded", you must encode your data with this format. You can simply do it with this code;
var values = ((Dictionary<string, string>)data).Aggregate(
new NameValueCollection(),
(seed, current) =>
{
seed.Add(current.Key, current.Value);
return seed;
});
So, your data is sent like "something=platform_secret&something2=1"
Now, you can send form data simply:
WebClient client = new WebClient();
var result = client.UploadValues(url, values);
I think your first function with signature public HttpRequests(string url, string method, Object data) dosn't seem have any logical error but in your second function with signature public Object performRequest() you have some issue:
if your HTTP method is GET you don't need to write content stream.
if your method is POST and your data are JSON you need setting up HTTP requester like this:
request.ContentType = "application/json";
and finally, flush your stream before you close it, like this request.Flush();
I am verifying my ios in app purchase receipt on my server using C# web service
I got receipt as string by doing below in Xcode:
- (void) completeTransaction: (SKPaymentTransaction *)transaction
{
NSString* receiptString = [[NSString alloc] initWithString:transaction.payment.productIdentifier];
NSLog(#"%#",receiptString);
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
NSString *jsonObjectString = [receipt base64EncodedStringWithOptions:0];
}
and I am sending that string(receipt) to my C# web service as parameter.
Here is my web service method:
[WebMethod(Description = "Purchase Item Verify")]
public string PurchaseItem(string receiptData)
{
string returnmessage = "";
try
{
var json = "{ 'receipt-data': '" + receiptData + "'}";
ASCIIEncoding ascii = new ASCIIEncoding();
byte[] postBytes = Encoding.UTF8.GetBytes(json);
HttpWebRequest request;
request = WebRequest.Create("https://sandbox.itunes.apple.com/verifyReceipt") as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = postBytes.Length;
Stream postStream = request.GetRequestStream();
postStream.Write(postBytes, 0, postBytes.Length);
postStream.Close();
var sendresponse = (HttpWebResponse)request.GetResponse();
string sendresponsetext = "";
using (var streamReader = new StreamReader(sendresponse.GetResponseStream()))
{
sendresponsetext = streamReader.ReadToEnd();
}
returnmessage = sendresponsetext;
}
catch (Exception ex)
{
ex.Message.ToString();
}
return returnmessage;
}
It always return {"status":21002}.
I have been searching for two days , but still can't find out the solution. Can someone help me, what am i wrong ?
**I am testing on sandbox that is why i use sandbox URL. I can verify the transaction receipt within my app.
I got solution
The final code that works for me is:
public string PurchaseItem(string receiptData)
{
string returnmessage = "";
try
{
// var json = "{ 'receipt-data': '" + receiptData + "'}";
var json = new JObject(new JProperty("receipt-data", receiptData)).ToString();
ASCIIEncoding ascii = new ASCIIEncoding();
byte[] postBytes = Encoding.UTF8.GetBytes(json);
// HttpWebRequest request;
var request = System.Net.HttpWebRequest.Create("https://sandbox.itunes.apple.com/verifyReceipt");
request.Method = "POST";
request.ContentType = "application/json";
request.ContentLength = postBytes.Length;
//Stream postStream = request.GetRequestStream();
//postStream.Write(postBytes, 0, postBytes.Length);
//postStream.Close();
using (var stream = request.GetRequestStream())
{
stream.Write(postBytes, 0, postBytes.Length);
stream.Flush();
}
// var sendresponse = (HttpWebResponse)request.GetResponse();
var sendresponse = request.GetResponse();
string sendresponsetext = "";
using (var streamReader = new StreamReader(sendresponse.GetResponseStream()))
{
sendresponsetext = streamReader.ReadToEnd().Trim();
}
returnmessage = sendresponsetext;
}
catch (Exception ex)
{
ex.Message.ToString();
}
return returnmessage;
Spending two and half days just to change a method. Thanks GOD.
Here's an alternative asynchronous implementation using HTTPClient:
public static async Task<string> CheckReceiptWithAppStore()
{
string responseStr = null;
string uri = "https://sandbox.itunes.apple.com/verifyReceipt";
string receiptData = // Get your receipt from wherever you store it
var json = new JObject(new JProperty("receipt-data", receiptData),
new JProperty("password", "paste-your-shared-secret-here")).ToString();
using (var httpClient = new HttpClient())
{
if (receiptData != null)
{
HttpContent content = new StringContent(json);
try
{
Task<HttpResponseMessage> getResponse = httpClient.PostAsync(uri, content);
HttpResponseMessage response = await getResponse;
responseStr = await response.Content.ReadAsStringAsync();
}
catch (Exception e)
{
Console.WriteLine("Error verifying receipt: " + e.Message);
}
}
}
return responseStr;
}
The shared secret is not required for non-subscription based purchases.
For managing subscriptions, #Jerry Naing's answer also requires the provision of your shared secret (can be retrieved/generated from iTunes Connect). Easiest way to include this is just to add an additional property in the line defining the json var.
var json = new JObject(new JProperty("receipt-data", receiptData), new JProperty("password", "put_your_shared_secret_here")).ToString();
Failing to provide the shared secret will result in a 21004 status response.
This code example was also helpful to me and may help others: For C# developers there is a useful open-source project called APNS-Sharp which includes receipt verification code that works in ASP.NET. In particular, the Receipt.cs and ReceiptVerification.cs files in the Jdsoft.Apple.AppStore directory
Found it from this page about Xamarin: inapp purcasing ios Transactions and Verification
I have a jquery routine that calls an MVC action which will do a PUT/POST to an API url. The call from jQuery is fine and works as well as the call to the API using C#. A response is received from the API in JSON format when checked via Firebug/Fiddler.
How do i get that response to be sent back to the calling jQuery?
My C# code is:
public string callAPIPut(string ApiUrl, string JsonString)
{
WebRequest request = WebRequest.Create(ApiUrl);
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes(JsonString);
request.ContentType = "application/json; charset=utf-8";
request.Method = WebRequestMethods.Http.Put;
request.ContentLength = JsonString.Length;
Stream newStream = request.GetRequestStream();
newStream.Write(data, 0, JsonString.Length);
newStream.Close();
return ""; // How do I return the JSON response from the API?
}
When doing a GET i could use something like the following to get the response back to the calling jQuery:
response = (HttpWebResponse)request.GetResponse();
using (StreamReader sr = new StreamReader(response.GetResponseStream()))
{
serviceResponse = sr.ReadToEnd();
}
return serviceResponse;
I dont know how to return the response when doing a Put/Post?
public ActionResult CallAPIPut(string ApiUrl, string JsonString)
{
using (var client = new WebClient())
{
client.Headers[HttpRequestHeader.ContentType] = "application/json";
byte[] data = Encoding.Default.GetBytes(JsonString);
byte[] result = client.UploadData(ApiUrl, "PUT", data);
return Content(Encoding.Default.GetString(result), "application/json");
}
}
or make it more intelligently, by wrapping in a custom and reusable action result to avoid cluttering your controller with infrastructure plumbing:
public class ApiResult : ActionResult
{
public ApiResult(string apiUrl, string jsonData)
: this(apiUrl, jsonData, "PUT")
{
}
public ApiResult(string apiUrl, string jsonData, string method)
{
ApiUrl = apiUrl;
JsonData = jsonData;
Method = method;
}
public string ApiUrl { get; private set; }
public string JsonData { get; private set; }
public string Method { get; set; }
public override void ExecuteResult(ControllerContext context)
{
var response = context.HttpContext.Response;
var contentType = "application/json";
response.ContentType = contentType;
using (var client = new WebClient())
{
client.Headers[HttpRequestHeader.ContentType] = contentType;
byte[] data = Encoding.Default.GetBytes(JsonData);
byte[] result = client.UploadData(ApiUrl, Method, data);
response.Write(Encoding.Default.GetString(result));
}
}
}
and now your controller action simply becomes:
public ActionResult CallAPIPut(string apiUrl, string jsonString)
{
return new ApiResult(apiUrl, jsonString);
}
Stream newStream = request.GetRequestStream();
newStream.Write(data, 0, JsonString.Length);
newStream.Close();
You're posting JSON to the server. To get JSON you need to post/put and use the ResponseStream to read the data the server returned.
A sample:
using System;
using System.IO;
using System.Net;
using System.Text;
namespace Examples.System.Net
{
public class WebRequestGetExample
{
public static void Main ()
{
// Create a request for the URL.
WebRequest request = WebRequest.Create (
"http://www.contoso.com/default.html");
// If required by the server, set the credentials.
request.Credentials = CredentialCache.DefaultCredentials;
// Get the response.
WebResponse response = request.GetResponse ();
// Display the status.
Console.WriteLine (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
Stream dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Clean up the streams and the response.
reader.Close ();
response.Close ();
}
}
}
Sample from http://msdn.microsoft.com/en-us/library/456dfw4f.aspx
Edit: You would return the responseFromServer and consume that in you're Javascript callback.
