Passing C# Web service Parameters to PHP Application

I am trying to passing C# Web service Parameters to PHP Application but not getting below is my code. Actually I am passing username and password xml format because no buddy should not see that credential while passing.
Below is my C# Web service using asp.net web form button click to redirect PHP application.
[WebMethod]
public string POSTXml(string username, string password)
{
WebRequest req = null;
WebResponse rsp = null;
try
{
StringBuilder strRequest = new StringBuilder();
string url = "http://xyz.in/getuser.php/";
req = WebRequest.Create(url);
req.Method = "POST";
req.ContentType = "text/xml";
StreamWriter writer = new StreamWriter(req.GetRequestStream());
writer.WriteLine(username,password);
writer.Close();
rsp = req.GetResponse();
var sr = new StreamReader(rsp.GetResponseStream());
string responseText = sr.ReadToEnd();
return responseText;
}
catch (Exception e)
{
throw new Exception("There was a problem sending the message");
}
}
Below is my button click code.
protected void Button2_Click(object sender, EventArgs e)
{
localhost.WebService objserv1 = new localhost.WebService();
Label.Text = objserv1.POSTXml("nagapavani", "tech#1234");
}
Actually when user will button click passing some values to web service and through web service want to pass that value to php application. Is there Other way to achieve that requirement. When I am going to button click not going to redirect and taken this code from google.

You could send the data as following. Convert it to a byte array and write it to the request stream:
[WebMethod]
public string POSTXml(string username, string password)
{
WebRequest req = null;
WebResponse rsp = null;
try
{
string data = "user=" + username + "&password=" + password;
string url = "http://xyz.in/getuser.php/";
byte[] buffer = Encoding.ASCII.GetBytes(data);
HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(url);
WebReq.Method = "POST";
WebReq.ContentType = "application/x-www-form-urlencoded";
WebReq.ContentLength = buffer.Length;
using (Stream PostData = WebReq.GetRequestStream())
{
PostData.Write(buffer, 0, buffer.Length);
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
using (Stream stream = WebResp.GetResponseStream())
{
using (StreamReader strReader = new StreamReader(stream))
{
return strReader.ReadToEnd();
}
}
WebResp.Close();
}
}
catch (Exception e)
{
throw new Exception("There was a problem sending the message");
}
return String.Empty;
}

Set a body for WebClient when making a Post Request

So I have an api that I want to call to. The first call is an ahoy call and in the body of the request I need to send the ship_type, piratename and my piratepass. I then want to read the response which has my treasure booty that i will use for later.
I'm able to do this with web request. but i feel like there is a better way to do it with webclient.
(way I currently do it in webrequest)
//Credentials for the Pirate api
string piratename = "IvanTheTerrible";
string piratepass= "YARRRRRRRR";
string URI = "https://www.PiratesSuperSecretHQ.com/sandyShores/api/respectmyauthority";
WebRequest wr = WebRequest.Create(URI);
wr.Method = "POST";
wr.ContentType = "application/x-www-form-urlencoded";
string bodyData = "ship_type=BattleCruiser&piratename=" + piratename + "&piratepass=" + piratepass;
ASCIIEncoding encoder = new ASCIIEncoding();
byte[] byte1 = encoder.GetBytes(bodyData);
wr.ContentLength = byte1.Length;
//writes the body to the request
Stream newStream = wr.GetRequestStream();
newStream.Write(byte1, 0, byte1.Length);
newStream.Close();
WebResponse wrep = wr.GetResponse();
string result;
using (var reader = new StreamReader(wrep.GetResponseStream()))
{
result = reader.ReadToEnd(); // do something fun...
}
Thanks in advance either way.

You can do with this simple code
Uri uri = new Uri("yourUri");
string data = "yourData";
WebClient client = new WebClient();
var result = client.UploadString(uri, data);
Remember that you can use UploadStringTaskAsync if you want to be async

You can try like below as well:
public String wcPost(){
Map<String, String> bodyMap = new HashMap();
bodyMap.put("key1","value1");
WebClient client = WebClient.builder()
.baseUrl("domainURL")
.build();
String responseSpec = client.post()
.uri("URI")
.headers(h -> h.setBearerAuth("token if any"))
.body(BodyInserters.fromValue(bodyMap))
.exchange()
.flatMap(clientResponse -> {
if (clientResponse.statusCode().is5xxServerError()) {
clientResponse.body((clientHttpResponse, context) -> {
return clientHttpResponse.getBody();
});
return clientResponse.bodyToMono(String.class);
}
else
return clientResponse.bodyToMono(String.class);
})
.block();
return responseSpec;
}

verifying iOS in app purchase receipt with C#

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

Posting image from .NET to Facebook wall using the Graph API

I'm using the Facebooks Javascript API to develop an application that will need to be able to post an image to a users wall.
That part of the app needs to be server-side as far as I can tell, since it needs to post the image data as "multipart/form-data".
Note: It's not the simple version using "post", but the real "photos" method.
http://graph.facebook.com/me/photos
I think I'm facing two problems, a .NET and a Facebook problem:
Facebook problem: I'm not quite sure if all parameters should be send as multipart/form-data (including the access_token and message). The only code example there is uses the cUrl util/application.
.NET problem: I have never issued multipart/form-data requests from .NET , and I'm not sure if .NET automatically creates the mime-parts, or if I have to encode the parameters in some special way.
It's a bit hard to debug, since the only error response I get from the Graph API is "400 - bad request".
Below is the code as it looked when I decided to write this question (yes, it's a bit verbose :-)
The ultimate answer would of course be a sample snippet posting an image from .NET, but I can settle for less.
string username = null;
string password = null;
int timeout = 5000;
string requestCharset = "UTF-8";
string responseCharset = "UTF-8";
string parameters = "";
string responseContent = "";
string finishedUrl = "https://graph.facebook.com/me/photos";
parameters = "access_token=" + facebookAccessToken + "&message=This+is+an+image";
HttpWebRequest request = null;
request = (HttpWebRequest)WebRequest.Create(finishedUrl);
request.Method = "POST";
request.KeepAlive = false;
//application/x-www-form-urlencoded | multipart/form-data
request.ContentType = "multipart/form-data";
request.Timeout = timeout;
request.AllowAutoRedirect = false;
if (username != null && username != "" && password != null && password != "")
{
request.PreAuthenticate = true;
request.Credentials = new NetworkCredential(username, password).GetCredential(new Uri(finishedUrl), "Basic");
}
//write parameters to request body
Stream requestBodyStream = request.GetRequestStream();
Encoding requestParameterEncoding = Encoding.GetEncoding(requestCharset);
byte[] parametersForBody = requestParameterEncoding.GetBytes(parameters);
requestBodyStream.Write(parametersForBody, 0, parametersForBody.Length);
/*
This wont work
byte[] startParm = requestParameterEncoding.GetBytes("&source=");
requestBodyStream.Write(startParm, 0, startParm.Length);
byte[] fileBytes = File.ReadAllBytes(Server.MapPath("images/sample.jpg"));
requestBodyStream.Write( fileBytes, 0, fileBytes.Length );
*/
requestBodyStream.Close();
HttpWebResponse response = null;
Stream receiveStream = null;
StreamReader readStream = null;
Encoding responseEncoding = System.Text.Encoding.GetEncoding(responseCharset);
try
{
response = (HttpWebResponse) request.GetResponse();
receiveStream = response.GetResponseStream();
readStream = new StreamReader( receiveStream, responseEncoding );
responseContent = readStream.ReadToEnd();
}
finally
{
if (receiveStream != null)
{
receiveStream.Close();
}
if (readStream != null)
{
readStream.Close();
}
if (response != null)
{
response.Close();
}
}

Here is a sample of how to upload binary data. But an uploading to /me/photos won't publish the image into wall :( The image saving into your app's album. I'm stuck on how to announce it in the feed. Yet another way is to post an image into "Wall Album", by URL=="graph.facebook.com/%wall-album-id%/photos". But didn't found any way to create sucha album (user creates it when uploading an image via the site).
{
string boundary = "---------------------------" + DateTime.Now.Ticks.ToString("x");

string formdataTemplate = "--{0}\r\nContent-Disposition: form-data; name=\"{1}\"\r\n\r\n{2}\r\n";
sb.AppendFormat(formdataTemplate, boundary, "access_token", PercentEncode(facebookAccessToken));

gui.OnUploadProgress(this, (int)(bytesTotal * 100 / imageLength));
}
strm_out.Write(trailingBytes, 0, trailingBytes.Length);
strm_out.Close();
HttpWebResponse wresp = uploadRequest.GetResponse() as HttpWebResponse;
}

Cleaned up class method using #fitz's code. Pass in a byte array or a file path for the image. Pass in an album id if uploading to an existing album.

You have to construct the multipart/form-data yourself using byte arrays.
Anyway I've already done this. You can check out the Facebook Graph Toolkit at http://computerbeacon.net/ . I'll update the toolkit to version 0.8 in a few days, which will include this "post photo to facebook wall" function as well as other new features and updates.

I was able to post pictures using RestSharp:
// url example: https://graph.facebook.com/you/photos?access_token=YOUR_TOKEN
request.AddFile("source", imageAsByteArray, openFileDialog1.SafeFileName, getMimeType(Path.GetExtension(openFileDialog1.FileName)));
request.addParameter("message", "your photos text here");

How to convert Image to Byte Array
Note: I was passing an empty string as the mime type and facebook was smart enough to figure it out.

Maybe useful

problem in uploading data with HttpWebRequest

Request you to please help me to solve my problem. I am new to web-services and HTTP.
I wrote following code to update data to website. Code run; but I am not able to see my data if uploaded. Here we have facility to see what data is getting uploaded but I am not able to see my data.
// Above URL is not real as I do not want to disclose real URL as of Now
Uri targetUrl = new Uri("http://www.x86map.com/post-embed/ewspost");

You may find it helps to include
requestStream.Flush();
before .Closeing it.
Stream.Flush

I do not see the code that actually gets the response. Is this want is missing?
using (var r = new StreamReader(request.GetResponse().GetResponseStream(), Encoding.UTF8))
result = r.ReadToEnd();
