I am trying to post data from PCL project to remote server. Below is my code:
public async Task<bool> SendToken(string deviceToken, string userId)
{
HttpWebRequest request;
string url = "http://192.168.1.171:91/api/updatePushDeviceToken";
request = (HttpWebRequest)WebRequest.Create(url);
request.ContentType = "application/x-www-form-urlencoded";
request.Accept = "application/json";
request.Method = "POST";
string postData = string.Format("userId={0};token={1}&deviceType={2}", userId, deviceToken, deviceType);
var data = Encoding.UTF8.GetBytes(postData);
try
{
request.BeginGetResponse(new AsyncCallback(FinishRequest), request);
}
catch (Exception e)
{
string m = e.Message;
}
return false;
}
private void FinishRequest(IAsyncResult result)
{
HttpWebResponse response = (result.AsyncState as HttpWebRequest).EndGetResponse(result) as HttpWebResponse;
Stream receiveStream = response.GetResponseStream();
StreamReader readStream = new StreamReader(receiveStream);
var responseString = readStream.ReadToEnd();
}
While running above code, below exception was thrown:
System.Net.WebException: The remote server returned an error: (411)
Length Required.
PCL doesn't contain ContentLength property, hence I added Length as below but now I am getting exception as:
try
{
request.Headers[HttpRequestHeader.ContentLength] = "0";
}
catch (Exception e)
{
}
System.ArgumentException: This header must be modified with the
appropiate property. at
System.Net.WebHeaderCollection.CheckRestrictedHeader (System.String
headerName)
Your request is missing of ContentLength property of your post parameters.
var parameters = Encoding.ASCII.GetBytes(qstring);
var request = (HttpWebRequest)HttpWebRequest.Create(url);
request.AllowAutoRedirect = false;
request.ContentType="application/x-www-form-urlencoded";
request.Method = "POST";
request.ContentLength = parameters.Length;
//Send it
var reqStream = request.GetRequestStream();
reqStream.Write(parameters, 0, parameters.Length);
reqStream.Close();
//read it
var response = (HttpWebResponse)request.GetResponse();
var sr = new StreamReader(response.GetResponseStream());
string responseHtml = sr.ReadToEnd().Trim();
And please use querystring format to post data, for example : "userId={0}&token={1}&..."

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 am getting '(400) Bad Request.' when I try complete authenticate against an ALM REST API, the first part (authentication) is successful) and I get the LWSSO_COOKIE_KEY, but site-session always fails with a 400 error code.
What am I doing wrong please... very confused!
// Authentication XML : 0 = User, 1 = Password
private const string AuthenticationXML = #"<alm-authentication>" +
"<user>{0}</user><password>{1}</password></alm-authentication>";
baseRequestURL = settings.QualityCentreURL + "/qcbin/";
Authentication is done first (and is successful) :
string authRequest = baseRequestURL + "authentication-point/alm-authenticate";
HttpWebRequest myauthrequest = (HttpWebRequest)WebRequest.Create(authRequest);
string xml = String.Format(AuthenticationXML, qcSettings.Username, qcSettings.Password);
byte[] Requestbytes = Encoding.UTF8.GetBytes(xml);
myauthrequest.Method = "POST";
myauthrequest.ContentType = "application/xml";
myauthrequest.ContentLength = Requestbytes.Length;
myauthrequest.Accept = "application/xml";
Stream RequestStr = myauthrequest.GetRequestStream();
RequestStr.Write(Requestbytes, 0, Requestbytes.Length);
RequestStr.Close();
HttpWebResponse myauthres = (HttpWebResponse)myauthrequest.GetResponse();
authenticationCookie = myauthres.Headers.Get("Set-Cookie");
The Site-Session code is :
public void GetSiteSession()
{
// Creat the web request fore site-session.
string request = baseRequestURL + "rest/site-session";
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(request);
string xml = String.Empty;
byte[] requestbytes = Encoding.UTF8.GetBytes(xml);
// Update the attributes before sending.
webRequest.Method = "POST";
webRequest.ContentType = "application/xml";
webRequest.Accept = "application/xml";
webRequest.Headers.Set(HttpRequestHeader.Cookie, authenticationCookie);
try
{
Stream requestStream = webRequest.GetRequestStream();
requestStream.Write(requestbytes, 0, requestbytes.Length);
requestStream.Close();
HttpWebResponse webRequestResponse = (HttpWebResponse)webRequest.GetResponse();
Stream responseStream = webRequestResponse.GetResponseStream();
XDocument doc = XDocument.Load(responseStream);
}
catch (System.Net.WebException except)
{
Console.WriteLine(except.Message);
}
}
I have tried cutting ;Path=/;HTTPOnly from LWSSO_COOKIE_KEY as per this question, but to no avail.
The API reference I found(here) seems to be a big vague or, possibly that I haven't understood it... :P
Apologies, it seems that with 12.53 I should have been using 'api/authentication/sign-in'
string requestURL = baseRequestURL + "api/authentication/sign-in";
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestURL);
var credentials = String.Format("{0}:{1}", qcSettings.Username, qcSettings.Password);
request.CookieContainer = authenticationCookieContainer;
request.Headers.Set(HttpRequestHeader.Authorization, "Basic " + Convert.ToBase64String(Encoding.UTF8.GetBytes(credentials)));
var authResponse = request.GetResponse();
errorString = String.Empty;
}
catch (System.Net.WebException except)
{
errorString = except.Message;
return false;
}
errorString = String.Empty;
return true;
}
public string GetShortURL(string longUrl)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.googleapis.com/urlshortener/v1/url?key=My_API_Key");
request.Method = "POST";
request.ContentType = "application/json";
string requestData = string.Format(#"{{""longUrl"": ""{0}""}}", longUrl);
byte[] requestRawData = Encoding.ASCII.GetBytes(requestData);
request.ContentLength = requestRawData.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(requestRawData, 0, requestRawData.Length);
requestStream.Close();
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader responseReader = new StreamReader(response.GetResponseStream());
string responseData = responseReader.ReadToEnd();
responseReader.Close();

I am trying to create short url by passing my original url string but it is giving an exception
I'm trying to use the check_eligibility call from the eBay Post-Order API in C# very unsuccessfully. Every time I get a bad response. Here is one way I've tried:
string url = "https://api.ebay.com/post-order/v2/cancellation/check_eligibility";
HttpWebRequest cancelOrderRequest = (HttpWebRequest)WebRequest.Create(url);
cancelOrderRequest.Headers.Add("Authorization", "TOKEN " + AuthToken);
cancelOrderRequest.ContentType = "application/json";
cancelOrderRequest.Accept = "application/json";
cancelOrderRequest.Headers.Add("X-EBAY-C-MARKETPLACE-ID", "EBAY_US");
cancelOrderRequest.Headers.Add("legacyOrderId", ebayFullOrderId);
cancelOrderRequest.Method = "POST";
HttpWebResponse response = (HttpWebResponse)cancelOrderRequest.GetResponse();
And here is another way I've tried:
string url = "https://api.ebay.com/post-order/v2/cancellation/check_eligibility";
var httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
httpWebRequest.Headers.Add("Authorization", "TOKEN " + AuthToken);
httpWebRequest.Headers.Add("X-EBAY-C-MARKETPLACE-ID", "EBAY_US");
httpWebRequest.Accept = "application/json";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{\"legacyOrderId\":\"###-###\"";
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
var result = streamReader.ReadToEnd();
}
Regardless of which way I try both came back with the same message, "The remote server returned an error: (400) Bad Request." If anyone could point me in the right direction I'd greatly appreciate it. Thanks.
My second code example ended up being the correct way to solve my problem. What I realized was my json was slightly off. I was missing the extra } at the end. The below updated json syntax fixed my problem going with the code from my second example.
var json = "{\"legacyOrderId\":\"" + ebayFullOrderId + "\"}";
Please try this code:
private void MakeRequests()
{
HttpWebResponse response;
if (RequestEbay(out response))
{
response.Close();
}
}
private bool RequestEbay(out HttpWebResponse response)
{
response = null;
try

request.Headers.Add("X-EBAY-API-COMPATIBILITY-LEVEL", #"967");

request.Method = "POST";

byte[] postBytes = System.Text.Encoding.UTF8.GetBytes(body);
request.ContentLength = postBytes.Length;
Stream stream = request.GetRequestStream();
stream.Write(postBytes, 0, postBytes.Length);
stream.Close();
