Question

我的双手在空中 - 我哭了，叔叔。帮助我理解：

我给客户写了一个简单的HttpWebRequest帖子＆＃39; https://website。它具有特定的头要求和JSON请求体。收到GetResponse StatusCode.OK后，GetResponseStream是由其服务器提供的错误。他们检查了他们的日志，并在标题出现时说，请求Body是＆＃34;。

这是我的代码：

    public const string API_URILogin = "https://dev.clientURL.com/test/api/login";
    private void RequestTest()
    {
        LoginAPIStruct loginInfo = new LoginAPIStruct();

        loginInfo.loginId = TestId;
        loginInfo.password = TestPw;
        loginInfo.vehicleType = "E";
        loginInfo.deviceId = "ABCDEF";
        loginInfo.clientId = "123456";
        loginInfo.appVersion = string.Empty;
        loginInfo.osType = string.Empty;
        loginInfo.osVersion = string.Empty;

        // Call LoginAPI
        string loginStatus = LoginAPI(loginInfo);
        //Display Results
        lblResults.Text = loginStatus;
    }


    // Public Variables
    public static string errorMessage;

    // ** Client Login **
    public static string LoginAPI(LoginAPIStruct loginInfo)
    {
        // Post Login to Client.  Get response with Vehicle structure.  
        string loginInfoSerialized = string.Empty;
        string returnString = string.Empty;

        loginInfoSerialized = new JavaScriptSerializer().Serialize(loginInfo);

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(API_URILogin);
        request.Method = "POST";
        request.ContentType = "application/json";
        request.Headers.Add("From", "CC");
        request.Headers.Add("Language", "0");
        request.Headers.Add("Offset", "-8");
        request.Headers.Add("To", "CCM");

        // Post Request
        using (StreamWriter streamPost = new StreamWriter(request.GetRequestStream()))
        {
            streamPost.Write(loginInfoSerialized);
        }

        // Get Response
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

        if (response.StatusCode == HttpStatusCode.OK)
        {
            // Status Okay.
            //string responseStatusDescription = response.StatusDescription;

            using (var streamReader = new StreamReader(response.GetResponseStream()))
            {
                try
                {
                    var result = streamReader.ReadToEnd();

                    returnString = result;
                }
                catch (Exception ex)
                {
                    returnString = ex.Message;
                }

            }
        }
        else
        {
            returnString = response.StatusCode.ToString();
        }

        return returnString;
    }   // end LoginAPI

我的JSON字符串似乎有效 - 我将其粘贴到Fiddler中，同时设置标题，Fiddler返回成功登录。

从ASP.Net，它返回所记录的错误，即需要电子邮件地址（loginId）。我的C＃代码中没有看到任何不正确的内容。还有什么想法可以看吗？客户端是否可以在其托管网站上阻止或过滤掉某个请求？我被卡住了。

所以，对于任何想要知道的人......你必须＆＃34;关闭＆＃34;执行.Write（payload）命令后的StreamWriter，否则它实际上并不发送数据。

    // Post Request
        StreamWriter streamPost = new StreamWriter(request.GetRequestStream());
        streamPost.Write(loginInfoSerialized);
        streamPost.Close();    //Don't forget to Close() or no data sent!!

我希望这可以帮助别人，因为我花了两周的时间来解决这个问题。侨

我会像这样发帖：

<script src="myscripts.js"></script>

ASP.Net httpwebrequest没有发布请求正文
