I want to call a rest client with basic authorization. I tried this but got a Unauthorized(401) exception in c# :
HttpWebRequest client = (HttpWebRequest)WebRequest.Create("http://someurl.com");
client.Method = "POST";
client.UseDefaultCredentials = true;
var encoding = new UTF8Encoding();
var bytes = Encoding.GetEncoding("iso-8859-1").GetBytes(mailinglist.ToString());
client.ContentLength = bytes.Length;
using (var writeStream = client.GetRequestStream())
{
writeStream.Write(bytes, 0, bytes.Length);
}
client.ContentType = "application/json";
NetworkCredential nc = new NetworkCredential("8ec5f23e-18ba-4154-9962-7ebefeb027c0", "");
//string credentials = String.Format("{0}:{1}", "8ec5f23e-18ba-4154-9962-7ebefeb027c0", "");
//byte[] bts = Encoding.ASCII.GetBytes(credentials);
//string base64 = Convert.ToBase64String(bts);
client.PreAuthenticate = true;
//string authorization = String.Concat("Basic ", base64);
//Utils.WriteLog("Addaudience", authorization);
//client.Headers.Add(HttpRequestHeader.Authorization, authorization);
client.Credentials = nc;
client.Accept = "application/json";
using (var response = (HttpWebResponse)client.GetResponse())
{
var responseValue = string.Empty;
if (response.StatusCode != HttpStatusCode.OK)
{
var message = String.Format("Request failed. Received HTTP {0}", response.StatusCode);
throw new ApplicationException(message);
}
// grab the response
using (var responseStream = response.GetResponseStream())
{
if (responseStream != null)
using (var reader = new StreamReader(responseStream))
{
responseValue = reader.ReadToEnd();
}
}
}
Please help me and tell me what is my mistake? I also tried to put Authorization string in the headers but not working.
Thanks.

I am tring to pull categories from my store on BigCommerce via API.
When I try my credentials at API Console;
https://developer.bigcommerce.com/console
it is working fine, but I when send credentials via C# post request it does not work.
I am receiving [{"status":401,"message":"No credentials were supplied in the request."}]
My code is like;
List<PostCredential> postCredentials = new List<PostCredential>();
postCredentials.Add(new PostCredential { name = "store_url", value = ApiPath });
postCredentials.Add(new PostCredential { name = "username", value = Username });
postCredentials.Add(new PostCredential { name = "api_key", value = ApiToken });
JavaScriptSerializer serializer = new JavaScriptSerializer();
string serialize = serializer.Serialize(postCredentials);
const string requestUrl = "https://myteststore1234.mybigcommerce.com/api/v2/categories.json";
StringBuilder postData = new StringBuilder();
postData.Append(serialize);
string postRequest = PostRequest(requestUrl, postData.ToString());
public static string PostRequest(string url, string postData)
{
HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create(url);
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] data = encoding.GetBytes(postData);
httpWReq.Method = "POST";
httpWReq.ContentType = "application/x-www-form-urlencoded";
httpWReq.ContentLength = data.Length;
using (Stream stream = httpWReq.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();
Stream responseStream = response.GetResponseStream();
if (responseStream != null)
{
string responseString = new StreamReader(responseStream).ReadToEnd();
return responseString;
}
return null;
}
is there any workaround for this?
WebHeaderCollection wHeader = new WebHeaderCollection();
wHeader.Clear();
//wHeader.Add("username:test");
//wHeader.Add("password:4afe2a8a38fbd29c32e8fcd26dc51f6d9b5ab99b");
//wHeader.Add("u","test:4afe2a8a38fbd29c32e8fcd26dc51f6d9b5ab99b");
string Username = "test";
string ApiToken = "4afe2a8a38fbd29c32e8fcd26dc51f6d9b5ab99b";
string sUrl = "https://store-bwvr466.mybigcommerce.com/api/v2/brands.json"; //txtstoreurl.Text.ToString() + "/api/v2/products.json";
HttpWebRequest wRequest = (HttpWebRequest)System.Net.HttpWebRequest.Create(sUrl);
wRequest.Credentials = new NetworkCredential(Username, ApiToken);
wRequest.ContentType = "application/json"; //' I don't know what your content type is
//wRequest.Headers = wHeader;
wRequest.Method = "GET";
HttpWebResponse wResponse = (HttpWebResponse)wRequest.GetResponse();
string sResponse = "";
using (StreamReader srRead = new StreamReader(wResponse.GetResponseStream()))
{
sResponse = srRead.ReadToEnd();
MessageBox.Show(sResponse);
}
After some research I found out I need to pass parameters like this;
httpWReq.Method = "GET";
httpWReq.ContentType = "application/json";
httpWReq.ContentLength = data.Length;
httpWReq.Credentials = new NetworkCredential(Username, ApiToken);
I am encountering a problem getting the access_token in client application using oauth.
The returned response has empty body though in API I can see the response is not empty.
tokenresponse = {
"access_token":"[ACCESSTOKENVALUE]",
"token_type":"bearer",
"expires_in":"1200",
"refresh_token":"[REFRESHTOKENVALUE]",
"scope":"[SCOPEVALUE]"
}
The method from API that returns the token http://api.sample.com/OAuth/Token:
public ActionResult Token()
{
OutgoingWebResponse response =
this.AuthorizationServer.HandleTokenRequest(this.Request);
string tokenresponse = string.Format("Token({0})", response!=null?response.Body:""));
return response.AsActionResult();
}
The client method that requests the token is:
public string GetAuthorizationToken(string code)
{
string Url = ServerPath + "OAuth/Token";
string redirect_uri_encode = UrlEncode(ClientPath);
string param = string.Format("code={0}&client_id={1}&client_secret={2}&redirect_uri={3}&grant_type=authorization_code",code, ClientId, ClientSecret, redirect_uri_encode);
HttpWebRequest request = HttpWebRequest.Create(Url) as HttpWebRequest;
string result = null;
request.Method = "POST";
request.KeepAlive = true;
request.ContentType = "application/x-www-form-urlencoded";
request.Timeout = 10000;
request.Headers.Remove(HttpRequestHeader.Cookie);
var bs = Encoding.UTF8.GetBytes(param);
using (Stream reqStream = request.GetRequestStream())
{
reqStream.Write(bs, 0, bs.Length);
}
using (WebResponse response = request.GetResponse())
{
var sr = new StreamReader(response.GetResponseStream());
result = sr.ReadToEnd();
sr.Close();
}
if (!string.IsNullOrEmpty(result))
{
TokenData tokendata = JsonConvert.DeserializeObject<TokenData>(result);
return UpdateAuthorizotionFromToken(tokendata);
}
return null;
}
The result variable is empty.
Please let me know if you have any idea what could cause this. Initially I assumed is because of the cookies so I tried to remove them from request.
Thanks in advance.
Dear just create webclient using following code and you will get json info in tokeninfo.I used it and simply its working perfect.
WebClient client = new WebClient();
string postData = "client_id=" + ""
+ "&client_secret=" + ""
+ "&grant_type=password&username=" + "" //your username
+ "&password=" + "";//your password :)
string soundCloudTokenRes = "https://api.soundcloud.com/oauth2/token";
string tokenInfo = client.UploadString(soundCloudTokenRes, postData);
You can then use substring that contains only token from tokeninfo.
To upload tracks on sound cloud.
private void TestSoundCloudupload()
{
System.Net.ServicePointManager.Expect100Continue = false;
var request = WebRequest.Create("https://api.soundcloud.com/tracks") as HttpWebRequest;
//some default headers
request.Accept = "*/*";
request.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.3");
request.Headers.Add("Accept-Encoding", "gzip,deflate,sdch");
request.Headers.Add("Accept-Language", "en-US,en;q=0.8,ru;q=0.6");
//file array
var files = new UploadFile[] { new UploadFile(Server.MapPath("Downloads//0.mp3"), "track[asset_data]", "application/octet-stream") };
//other form data
var form = new NameValueCollection();
form.Add("track[title]", "Some title");
form.Add("track[sharing]", "public");
form.Add("oauth_token", "");
form.Add("format", "json");
form.Add("Filename", "0.mp3");
form.Add("Upload", "Submit Query");
try
{
using (var response = HttpUploadHelper.Upload(request, files, form))
{
using (var reader = new StreamReader(response.GetResponseStream()))
{
Response.Write(reader.ReadToEnd());
}
}
}
catch (Exception ex)
{
Response.Write(ex.ToString());
}
}
The gitWebRequest.GetResponse() line is returning a 403 error from the server and I can't seem to figure out why. Any help appreciated.
var address = new Uri(verifyUrl + _apiKey);
HttpRequest request = HttpContext.Current.Request;
var gitWebRequest = WebRequest.Create(address) as HttpWebRequest;
gitWebRequest.Method = "POST";
gitWebRequest.ContentType = "application/json";
var requestReader = new StreamReader(request.InputStream);
var requestBody = requestReader.ReadToEnd();
var myRequestUri = string.Format("{0}://{1}{2}",request.Url.Scheme,request.Url.Authority.TrimEnd('/'), request.RawUrl);
var verifyRequestData = new { requestUri = myRequestUri, postBody = requestBody };
var gitRequestData = Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(verifyRequestData));
using (var stream = gitWebRequest.GetRequestStream())
{
stream.Write(gitRequestData, 0, gitRequestData.Length);
}
using (var response = gitWebRequest.GetResponse() as HttpWebResponse)
{
// Get the response stream
if (response != null)
{
var responseReader = new StreamReader(response.GetResponseStream());
result = responseReader.ReadToEnd();
}
}
It was using http instead of https, which is what goole requires.
Thanks for making me look at the url.
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");
HttpWebRequest request = null;
StringBuilder sb = new StringBuilder();
Stream requestStream = null;
try
{
request = (HttpWebRequest)WebRequest.Create(targetUrl);
using (StreamReader inputReader = new StreamReader("C:\\SupportXml.xml"))
{
sb.Append(inputReader.ReadToEnd());
}
String postData = sb.ToString();
byte[] postDataBytes = Encoding.UTF8.GetBytes(postData);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = postDataBytes.Length;
request.KeepAlive = true;
request.Accept = "*/*";
request.Headers.Add("Cache-Control", "no-cache");

requestStream = request.GetRequestStream();
requestStream.Write(postDataBytes, 0, postDataBytes.Length);
}
catch (Exception ex)
{
Console.Write(ex.ToString());
}
finally
{
if (null != requestStream)
requestStream.Close();
}
URL I mentioned in Code is not real. Please let me know what is the problem in my code.
Following is the Java code working perfect. I want to convert same code in C#.
// Above URL is not real as I do not want to disclose real URL as of Now

while ((line = input.readLine()) != null)
{
s.append(line);
s.append(System.getProperty("line.separator"));
}
String xmlDataString = s.toString();
int length = xmlDataString.length();
System.out.println("length " + length);
URL url = new URL(urlString);
System.out.println(url.toString());
HttpURLConnection connection = (HttpURLConnection)url.openConnection();

BufferedOutputStream bos = new BufferedOutputStream(connection.getOutputStream());
BufferedReader reader = new BufferedReader(new StringReader(xmlDataString));
System.out.println("Proxy Used :" + connection.usingProxy());
int dataRead;
bos.write("XML_string=".getBytes());
while ((dataRead = reader.read()) != -1)
{
bos.write(dataRead);
}
bos.flush();
bos.close();
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String res = null;
while ((res = br.readLine()) != null)
{
}
br.close();
}
catch (IOException e)
{
e.printStackTrace();
}
Please help me to resolve this issue.
Thanks and Regards,

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();
