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();
}

我尝试过使用HttpWebRequest以及httpClient。我在这里看了十几个问题，但没有人帮助过这种情况。

我可以使用PHP和Curl来获得我想要的结果。 PHP中返回的数据是JSON链接列表。看起来像这样..

API I am trying to utilize。它成功登录但我无法获得登录调用的数据。

我认为curl调用和httpclient调用存在差异，但我不确定。

任何帮助表示赞赏。我已将代码编辑为以下内容，但响应字符串仍为空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();
    }

这是有效的卷曲调用

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.

使用：

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

结果将在responseString。

还有一个问题：

您将BaseAddress设置为CloudApi，因此当您致电requestUri时，PostAsync应为空白。像这样：

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

也帮自己一个忙，并使用C＃提供的using关键字。

所以这就是你的完整方法应该是什么样的：

    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();

C＃httpClient不返回内容
