Question

我正在写一个本地C＃WCF服务。我有它工作正常，除了它需要与https api进行交互的地方。每当我尝试获取/发布到https时，我都会得到一个socketexception（16010）（与http调用一起工作正常）

示例：

    private async void test()
    {
        var client = new System.Net.Http.HttpClient();

        //The next line works just fine, I get a response back
        var r = await client.GetAsync("http://www.google.com/appsstatus/rss/en");
        HttpContent responseContent = r.Content;

        //SOCKETEXCEPTION 16010 at next line
        var r2 = await client.GetAsync("https://www.google.com/appsstatus/rss/en");           
        HttpContent responseContent2 = r2.Content;
    }

当我通过visual studio调试器（iis express）运行我的服务时，以及当我在我的凭据上运行应用程序池的本地完整IIS服务器上托管它时，就会发生这种情况。

我不确定如何开始追逐这个。任何指针都将非常感激。

异常详细信息：

System.Net.Sockets.SocketException occurred
Message: A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.dll
Additional information: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

使用ServiceStack

             var a = "https://www.google.com/appsstatus/rss/en".GetXmlFromUrl();

我得到以下内容：

System.Net.Sockets.SocketException occurred
  _HResult=-2147467259
  _message=A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

  NativeErrorCode=10060

您确定第一次调用不是处置或更改client对象的状态吗？你试过这个吗？

var client = new System.Net.Http.HttpClient();

    //The next line works just fine, I get a response back
    var r = await client.GetAsync("http://www.google.com/appsstatus/rss/en");
    HttpContent responseContent = r.Content;

    //SOCKETEXCEPTION 16010 at next line
    client = new System.Net.Http.HttpClient();
    var r2 = await client.GetAsync("https://www.google.com/appsstatus/rss/en");           
    HttpContent responseContent2 = r2.Content;

从本地WCF服务的GET / POST到https的SocketException 16010
