问题描述
我有一个授权代码，我需要在调用api时使用一些标头值传入正文。当从邮递员那里尝试同样的工作时它的工作正常，但C＃Webclient抛出403错误。
I have a Authorization code which i need to pass in body with some header value when calling a api. when trying the same from postman its working fine but C# Webclient throwing 403 error.
以下代码： -
public string GetResponse（string AuthCode）
      {
public string GetResponse(string AuthCode)
{
  string url =" https://example.com//openam/oauth2/access_token？grant_type = authorization_code& realm = / cbpgatqa" ;;
          Uri uri = new Uri（string.Format（url））;
          ASCIIEncoding encoding = new ASCIIEncoding（）;
          string postData =" code =" + AuthCode +"& redirect_uri =" +" http：// localhost：8080";
          byte [] data = Encoding.GetEncoding（" UTF-8"）。GetBytes（postData）;
          //创建请求
          var httpWebRequest =（HttpWebRequest）WebRequest.Create（uri）;
          httpWebRequest.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
          httpWebRequest.Headers.Add（HttpRequestHeader.Authorization，" Basic" + AuthCode）;
          httpWebRequest.ContentType =" application / json";
          httpWebRequest.Method =" POST";
          httpWebRequest.ContentLength = data.Length;
          httpWebRequest.UserAgent = @" Mozilla / 5.0（Windows NT 10.0; Win64; x64）AppleWebKit / 537.36（KHTML，与Gecko一样）Chrome / 51.0.2704.106 Safari / 537.36" ;;
          Stream stream = httpWebRequest.GetRequestStream（）;
          stream.Write（data，0，data.Length）;
          stream.Close（）;
          //获取回复
          HttpWebResponse httpResponse = null;
         试试
          {
              httpResponse =（HttpWebResponse）httpWebRequest.GetResponse（）;
          }¥b $ b           catch（例外情况）
          {
              Console.WriteLine（"获取资源时的异常"+"ex.Message"）;
             返回null;
          }
          string result = null;
         使用（var streamReader = new StreamReader（httpResponse.GetResponseStream（））））
          {
              result = streamReader.ReadToEnd（）;
          }
         返回结果;
string url = "https://example.com//openam/oauth2/access_token?grant_type=authorization_code&realm=/cbpgatqa";
Uri uri = new Uri(string.Format(url));
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "code=" + AuthCode + "&redirect_uri=" + "http://localhost:8080";
byte[] data = Encoding.GetEncoding("UTF-8").GetBytes(postData);
// Create the request
var httpWebRequest = (HttpWebRequest)WebRequest.Create(uri);
httpWebRequest.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
httpWebRequest.Headers.Add(HttpRequestHeader.Authorization, "Basic " + AuthCode);
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
httpWebRequest.ContentLength = data.Length;
httpWebRequest.UserAgent = @"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.106 Safari/537.36";
Stream stream = httpWebRequest.GetRequestStream();
stream.Write(data, 0, data.Length);
stream.Close();
// Get the response
HttpWebResponse httpResponse = null;
try
{
httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
}
catch (Exception ex)
{
Console.WriteLine("Exception while getting resource " + ex.Message);
return null;
}
string result = null;
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
return result;
}
