I'm communicating with an API and I can perform a GET command with ease!....
I am having issues getting the POST to go through.......
This is the error I receive:
"{\"error\":\"no data object in post\"}"
I'm not getting the JSON passed to the POST. What am I missing??
Here is how my JSON String should be assembled: This works in Postman.
{
"data": {
"comments": "test comment",
"lng": -96.7922,
"lat": 46.87515
}
}
Here is my code:
WebRequest req = WebRequest.Create(#"https://the url.com/test?apiKey=testkey");
req.ContentType = "application/json";
req.Method = "POST";
req.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("username:password"));
using (var streamWriter = new StreamWriter(req.GetRequestStream()))
{
var jsonstr = new Data
{
Comments = "hello world",
Lng = -86.7922,
Lat = 36.87515
};
string json = new JavaScriptSerializer().Serialize(jsonstr);
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
}
HttpWebResponse resp = req.GetResponse() as HttpWebResponse;
var httpResponse = (HttpWebResponse)req.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
Here is the Data Class:
public partial class Data
{
[JsonProperty("type")]
public string Type { get; set; }
[JsonProperty("features")]
public Feature[] Features { get; set; }
[JsonProperty("lat")]
public double Lat { get; set; }
[JsonProperty("lng")]
public double Lng { get; set; }
[JsonProperty("comments")]
public string Comments { get; set; }
}
Thanks

I think that happens because you're not specifying content length. It also (but unlikely) can be Accept header missing. Here is a snipped from my code for any REST client:
Prepare request (body is a string variable with serialized content):
HttpWebRequest Request = WebRequest.CreateHttp(BaseAddress.Uri);
if (!string.IsNullOrWhiteSpace(method))
Request.Method = method;
else
Request.Method = "GET";
Request.Headers.Add("Authorization", BasicAuthInfo);
Request.Accept = "application/json";
if (!string.IsNullOrWhiteSpace(body))
{
UTF8Encoding encoding = new UTF8Encoding();
byte[] byteBody = encoding.GetBytes(body);
Request.ContentLength = byteBody.Length;
using (Stream dataStream = Request.GetRequestStream())
dataStream.Write(byteBody, 0, byteBody.Length);
if (string.IsNullOrEmpty(Request.ContentType))
Request.ContentType = "application/json";
}
Make a query (where PrepareHttpWebRequest is call to previous snippet):
protected string JSONQuery(string subPath, string query = null, string method = null, NameValueCollection extraHeaders = null, string body = null)
{
HttpWebRequest Request = PrepareHttpWebRequest(AuthenticationMethod.Basic, subPath, query, method, extraHeaders, body);
using (WebResponse Response = Request.GetResponse())
{
using (Stream ResponseStream = Response.GetResponseStream())
{
using (StreamReader Reader = new StreamReader(ResponseStream, Encoding.UTF8))
{
string result = Reader.ReadToEnd();
return result;
}
}
}
}

I'm trying to make web requests programmatically in ASP.NET, using the POST method.
I'd like to send POST parameters with the web request as well. Something like this:
LoginData obj = new LoginData();
obj.OSVersion = deviceInformation.OperatingSystem;
obj.DeviceModel = deviceInformation.FriendlyName;
string URI = "https://XXXXXXXXX.azure-mobile.net/user/logsuserin";
HttpWebRequest GETRequest = (HttpWebRequest)HttpWebRequest.Create(new Uri(URI, UriKind.RelativeOrAbsolute));
GETRequest.Method = "POST";
GETRequest.ContentType = "application/x-www-form-urlencoded";
GETRequest.Headers["applicationKey"] = "UFakeKkrayuAeVnoVAcjY54545455544";
//GETRequest.Parameters.add(obj);
Obviously, the commented line does not work. How do I achieve this?
How to get a response by sending my obj as params?
Thanks in advance,
Hemanth.
You need to use theGetRequestStream() method belonging to the HttpWebRequest
void Main()
{
LoginData obj = new LoginData
{
Username = "foo",
Password = "Bar"
};
byte[] objBytes = Encoding.UTF8.GetBytes(obj.ToString());
// obj.OSVersion = deviceInformation.OperatingSystem;
// obj.DeviceModel = deviceInformation.FriendlyName;
string URI = "https://XXXXXXXXX.azure-mobile.net/user/logsuserin";
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(URI, UriKind.RelativeOrAbsolute));
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.Headers["applicationKey"] = "UFakeKkrayuAeVnoVAcjY54545455544";
request.ContentLength = objBytes.Length;
using (Stream stream = request.GetRequestStream())
{
stream.Write(objBytes, 0, objBytes.Length);
}
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
using (Stream stream = response.GetResponseStream())
using (StreamReader reader = new StreamReader(stream))
{
Console.WriteLine(reader.ReadToEnd());
}
}
public class LoginData
{
public string Username { get; set; }
public string Password { get; set; }
public string OSVersion { get; set; }
public string DeviceModel { get; set; }
public override string ToString()
{
var temp = this.GetType()
.GetProperties()
.Select(p => $"{p.Name}={HttpUtility.UrlEncode(p.GetValue(this).ToString())}");
return string.Join("&", temp);
}
}
If you want to use HttpClient:
using (var client = new HttpClient())
{
var request = new HttpRequestMessage(HttpMethod.Post, "https://XXXXXXXXX.azure-mobile.net/user/logsuserin");
request.Headers.Add("applikationKey", "UFakeKkrayuAeVnoVAcjY54545455544");
request.Content = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("OSVersion", deviceInformation.OperatingSystem),
new KeyValuePair<string, string>("DeviceModel", deviceInformation.FriendlyName),
});
var response = client.SendAsync(request).GetAwaiter().GetResult();
}
You can dynamically generate a FORM with "NameValueCollection". Using "NameValueCollection" you can add number of objects to be posted as -
NameValueCollection FormFields = new NameValueCollection();
FormFields.Add("abc", obj1);
FormFields.Add("xyz", obj2);
Response.Clear();
Response.Write("<html><head>");
Response.Write(string.Format("</head><body onload=\"document.{0}.submit()\">", FormName));
Response.Write(string.Format("<form name=\"{0}\" method=\"{1}\" action=\"{2}\" >", FormName, Method, Url));
for (int i = 0; i < FormFields.Keys.Count; i++)
{
Response.Write(string.Format("<input name=\"{0}\" type=\"hidden\" value=\"{1}\">", FormFields.Keys[i], FormFields[FormFields.Keys[i]]));
}
Response.Write("</form>");
Response.Write("</body></html>");
Response.End();
OnLoad() of this form you can POST to desired URL.
I'm trying to log in into iCloud using a Json Post request in C#. Before trying to implement the code I was studying a little bit the iCloud requests using Chrome Console and using an Ad-on to replicate the requests in order to obtain the same result of the website.
First of All I checked the request directly from iCloud website:
And this is the response:
{
"serviceErrors" : [ {
"code" : "-20101",
"message" : "Il tuo ID Apple o la password non sono corretti."
} ]
}
Using "Advance REST Client" ad Chrome plugin to replicate the request I ve tried the same Json request to the same Url. But I get Empty response:
I Also tried to copy and paste the whole Header (All the settings) and than send the request but the response is the same:
Anyone has an Advice?
UPDATE: I tried to implement A Json request through c# program:
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://idmsa.apple.com/appleauth/auth/signin");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{accountName: \"briesanji #gmail.com\", password: \"testPassword\", rememberMe: false, trustTokens: []}";
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
The problem is that Execution breaks when the
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
is hit and it gives me this error: System.Net.WebException: 'Error Remote Server: (400) Request not valid.'
UPDATE: I solved in this way:
void POST(string url, string jsonContent)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
Byte[] byteArray = encoding.GetBytes(jsonContent);
request.ContentLength = byteArray.Length;
request.ContentType = #"application/json";
using (Stream dataStream = request.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
}
long length = 0;
try
{
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
length = response.ContentLength;
}
}
catch (WebException ex)
{
// Log exception and throw as for GET example above
}
}
string GET(string url)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
try
{
WebResponse response = request.GetResponse();
using (Stream responseStream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
return reader.ReadToEnd();
}
}
catch (WebException ex)
{
WebResponse errorResponse = ex.Response;
using (Stream responseStream = errorResponse.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
String errorText = reader.ReadToEnd();
// log errorText
}
throw;
}
}
Anyways I tested also the Answer and it was good to.. So I check it as valid thanks.
With this i dont get any error and the response content of the second request just tells me that there were too many failed logins for the test account...

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'm trying to connect Django API with c # but when I connect I face a problem in C#.
Django here I use as a server API and C# as a client.

Do you accept POST requests in your Django view? If yes, you should use #csrf_exempt decorator for the view that handles POST requests. The other option is to provide CSRF token from C# side.
Guyz facing problems with creating a push notification service (for android) using Google C2DM which uses OAuth 2.0 . I am sort of newbie dev , and the deadline is on the head ! Please help !
