向HttpClient添加两个头文件

当它只是授权头文件时，我有此工作。但现在我需要添加一个自定义标题。 tokenResponse中出现错误，标题为“HEADER OUT OF RANGE”。向HttpClient添加两个头文件

这里的端点信息：

URI: https://api.xyzcompany.com/api/v10/proxyUserToken 
METHOD: POST 
Params: email 
Required headers: X-iMem-Date, Authorization

我的代码。

  //get current date and time 
      DateTime dt = DateTime.Now; 
      string date = string.Format("{0:ddd}, {0: dd MMM yyyy HH:mm:ss} GMT", dt); 

      //hash together for header 
      string strToHash = secret + date + "[email protected]"; 
      string hash = SHA.Generate256string(strToHash); 

      //setup the values we need to post 
      var values2 = new Dictionary<string, string>(); 
      values2.Add("email", "[email protected]"); 
      var content2 = new FormUrlEncodedContent(values2); 

      //setup the auth header 
      string auth = string.Format("IMEM {0}:{1}", token, hash); 

      //setup client and add the headers 
      HttpClient client2 = new HttpClient(); 
      client2.BaseAddress = new Uri(postURL); 
      client2.DefaultRequestHeaders.Add("X-iMem-Date", date); 
      client2.DefaultRequestHeaders.Add("Authorization", auth); 

      //post and get responses 
      HttpResponseMessage response2 = await client2.PostAsync(new Uri(postURL), content2); 
      var tokenresponse = await response2.Content.ReadAsStringAsync(); 
      if (response2.IsSuccessStatusCode) 
      { 
       ...do stuff... 
      }

当您使用DefaultRequestHeaders并尝试添加自定义标题，它会尝试验证对众所周知的头，因为你有什么是定制它失败。 VAR请求=新HttpRequestMessage（HttpMethod.Post：
你应该使用HttpRequestMessage
https://msdn.microsoft.com/en-us/library/system.net.http.headers.httprequestheaders(v=vs.118).aspx

var request = new HttpRequestMessage(HttpMethod.Post, new Uri(requestUrl)); 
request.Headers.Add("Your-Custom-Header", "Value"); 
request.Content = "{your request content}"

然后

var response = await httpClient.SendAsync(request);

使这些变化，但仍然获得头超出范围形成Request ，新Uri（postURL））; request.Headers.Add（“X-iMem-Date”，date）; request.Headers.Add（“Authorization”，auth）; request.Content = content; response.Content.ReadAsStringAsync（）; var response = await httpclient.SendAsync（request）; –

是您的日期字符串格式正确，服务器预期的格式？ –

也使用'DateTime.UtcNow'而不是'DateTime.Now' –
