C＃httpClient不返回內容

Question

public const string CloudApi = "https://www.idxhome.com/restServices/cloud-idx/login"; 
public const string password = "cloudidx"; 
public const string clientId = "65912"; 
public async Task<ActionResult> Index() 
{ 
    HttpClient client = new HttpClient(); 
    client.BaseAddress = new Uri(CloudApi); 
    client.DefaultRequestHeaders.Accept.Clear(); 

    var values = new Dictionary<string, string> 
    { 
     { "clientId", "cloudidx" }, 
     { "password", "65912" } 
    }; 

    var content = new FormUrlEncodedContent(values); 
    HttpResponseMessage response = await client.PostAsync(CloudApi,content); 

    if (response.IsSuccessStatusCode) 
    { 
     var responseString = response.Content.ReadAsStringAsync().Result; 

     response.Content.ToString(); 
    } 

    client.Dispose(); 

    return View(); 
} 

我試過使用HttpWebRequest以及httpClient。 我在這裏看了大約十幾個問題，他們都沒有幫助過這種情況。

我可以使用PHP和Curl並獲得我期待的結果。 PHP中返回的數據是JSON鏈接列表。看起來像這樣..

API I am trying to utilize。它以成功登錄，但我無法獲取登錄呼叫所傳遞的數據。

我相信curl調用和httpclient調用有所不同，但我不確定。

任何幫助表示讚賞。 我已編輯的代碼以下，但響應字符串仍然是空Copy of debug view

 public async Task<ActionResult> Index() 
    { 
     using (var client = new HttpClient()) { 
     client.BaseAddress = new Uri(CloudApi); 
     client.DefaultRequestHeaders.Accept.Clear(); 
     //client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 
     var values = new Dictionary<string, string> 
     { 
      { "clientId", "65912" }, 
      { "password", "cloudidx" } 

     }; 
     var content = new FormUrlEncodedContent(values); 
     HttpResponseMessage response = await client.PostAsync("login", content); 
      string responseString = String.Empty; 
      if (response.IsSuccessStatusCode) 
     { 
      responseString = await response.Content.ReadAsStringAsync(); 

     } 
    } 
     return View(); 
    } 

這裏是捲曲呼叫工作

function cloudIDXCall($url, $method, $data = array()) { 

$curl = curl_init(); 
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // return response as a string 
curl_setopt($curl, CURLOPT_SSLVERSION, 3); // force default SSL version to 3  
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // turn off verification of the remote server's certificate - helps with Windows 

$queryString = http_build_query($data); // pack parameters into a URL query string 

if ($method == 'get') { 
    // GET is the default request method for cURL 
    if (strlen($queryString) > 0) $url = $url . '?' . $queryString; // append parameters for GET 
} elseif ($method == 'post') { 
    curl_setopt($curl, CURLOPT_POST, 1); 
    curl_setopt($curl, CURLOPT_POSTFIELDS, $queryString); // set parameters for POST 
} else { 
    return array('failure' => 'Invalid method'); 
} 

curl_setopt($curl, CURLOPT_URL, $url); 
$response = curl_exec($curl); 

if (!$response) { 
    $errMsg = "Error: " . curl_error($curl) . " - Code: " . curl_errno($curl); 
    curl_close($curl); 
    return array('failure' => $errMsg); 
} 

$responseArray = json_decode ($response, $assoc = true); // decode JSON into assoc array 
curl_close($curl); 
return $responseArray; 

}

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3; solved the issue... Not sure why it made a difference but it did.

用途：

var responseString = await response.Content.ReadAsStringAsync(); 

結果將在responseString。

而且更一個問題：

您設定BaseAddress爲CloudApi，所以現在當你調用PostAsync應該是空白requestUri。像這樣：

var response = await client.PostAsync(String.Empty, content); 

也請你幫個忙，並使用C＃提供的using關鍵字。

因此，這裏是你的完整的方法應該是什麼樣子：

using(var client = new HttpClient()) 
    { 
     client.BaseAddress = "http://baseApiAddress.com"; 

     var values = new Dictionary<string, string> 
     { 
      { "clientId", "cloudidx" }, 
      { "password", "65912" } 
     }; 

     var content = new FormUrlEncodedContent(values); 
     var response = await client.PostAsync("apiMethod", content); 
     string responseString = String.Empty; 

     if(response.IsSuccessStatusCode) 
     { 
      responseString = await response.Content.ReadAsStringAsync(); 
     } 
    } 

    return View();
