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 =" example//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 = "example//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=" + "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;
