c#-4.0 - Windows azure - 无法从传输连接读取数据: An existing connection was forcibly closed by the remote host

Question

使用 JsonTextReader 读取数据时出现以下异常

无法从传输连接读取数据:现有连接被远程主机强制关闭。

JsonTextReader jsonReader - 参数

 while (hasRecords(jsonReader, JsonToken.StartObject, null, null)) //Row
        {
            ...

            //it's ok to read this all into memory - it's just one row's worth of data
            JArray values = (JArray)JToken.ReadFrom(jsonReader);

此外，为了更清楚起见，还包括 HttpPost 实现的代码

 HttpClientHandler handler = new HttpClientHandler() { Credentials = taskProfileInfo.Credential };

        HttpClient httpClient = new HttpClient(handler) { Timeout = TimeSpan.FromSeconds(taskProfileInfo.CommandTimeout) };
        httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));


        HttpResponseMessage response;

        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url);
        request.Content = new StringContent(postBody, Encoding.UTF8, "application/json");

        response = await httpClient.SendAsync(request, HttpCompletionOption.ResponseHeadersRead);

        response.EnsureSuccessStatusCode();

        //using (var responseStream = await response.Content.ReadAsStreamAsync())
        //{
        //    using (var reader = new StreamReader(responseStream))
        //    {
        //        responseFromAPI = reader.ReadToEnd();
        //    }
        //}

        return new JsonTextReader(new StreamReader(await response.Content.ReadAsStreamAsync()));

感谢任何人可以帮助我们..

编辑:请注意，我们能够在本地调试它并且工作正常。只有当我们在 Azure 云服务中将其作为辅助角色运行时才会出现问题。

我终于解决了这个问题。只是为了关闭这个(可能对某人有帮助) -

After doing remote debugging我们发现以下内部异常:{“请求已中止:请求已取消。”}

而且，此问题的根本原因是我们将超时设置为小于实际读取 (JsonTextReader) 操作所需的超时时间。下面的代码行设置超时:

 HttpClient httpClient = new HttpClient(handler) { Timeout = TimeSpan.FromSeconds(taskProfileInfo.CommandTimeout) };

因此，修复方法是增加超时值，以便读取数据时请求不会被取消。
