在C#中通过SSLStream发送GET命令？

Question

我正在编写一个http自动化框架,我的问题是与经过身份验证的http 安全连接进行通信.在做了一些研究之后,我发现了C#中的SslStream对象,它可以很容易地与我现有的客户端架构集成.问题是; 尽管能够验证我与给定Web服务器的连接,但任何"GET [website] HTTP/1.1"命令似乎只返回标题而不是实际的网页.

我有一种感觉,我没有正确地形成我的网络请求,但我真的不知道.我整个上午一直在做研究,在这个特定的问题上找不到很多资源.这是我项目的代码示例:

    private IAsyncResult Request(HttpRequestToken token, ReceiveEvent callback) 
    {
        if (token == null)
            throw new Exception("Error. No request information provided. Aborting operation.");

        //Setup the TCP Information. (_port is set to 443 for SSL purposes)
        var client = new TcpClient(token.Host, _port);

        //Get a handle to a networkstream for writing data.
        var requestStream = new SslStream(client.GetStream(), false, null);

        //Authenticate the request
        requestStream.AuthenticateAsClient(token.Host);

        //Translate the data.
        byte[] sendBuffer = UTF8Encoding.UTF8.GetBytes(token.ToString());

        //NOTE: The results of the above command will look like this:
        //GET [website] HTTP/1.1
        //Host: [host]
        //passive: true
        //Accepts: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
        //User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1 Fennec/2.0.1

        //Send the data.
        requestStream.Write(sendBuffer);

        //Get the string value with a function that just iterates over the stream.
        string val = readStream(requestStream);

        //Breakpoint here, this code is not complete but "functions".
        return null;
    }

从本质上讲,我的代码的结果只会返回带有一些标题信息的"HTTP/1.1 200 OK".标题之外不会返回HTML或任何其他内容.

正如所要求的,这里有更多信息:

    private string readStream(Stream stream)
    {
        byte[] resultBuffer = new byte[2048];
        string value = "";
        //requestStream.BeginRead(resultBuffer, 0, resultBuffer.Length, new AsyncCallback(ReadAsyncCallback), new result() { buffer = resultBuffer, stream = requestStream, handler = callback, asyncResult = null });
        do
        {
            try
            {
                int read = stream.Read(resultBuffer, 0, resultBuffer.Length);
                value += UTF8Encoding.UTF8.GetString(resultBuffer, 0, read);

                if (read < resultBuffer.Length)
                    break;
            }
            catch { break; }
        } while (true);
        return value;
    }

出于测试目的,我试图访问谷歌Android开发人员门户网站(因为它使用SSL).这只是加载登录页面,除了页面加载请求之外,此时甚至不传输任何信息.这是我的确切要求.

GET https://accounts.google.com/ServiceLogin HTTP/1.1
Host: accounts.google.com
passive: true
nui: 1
continue: https://market.android.com/publish
followup: https://market.android.com/publish
Accepts: text/html,application/xhtml+xml,application/xml;q=0.9,
User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1 Fennec/2.0.1

这是服务器响应:

感谢您抽出宝贵时间来查看我的问题,我很感激!如果您想了解我的更多信息,我很乐意给予.因为我认为我的错误可能是一个愚蠢的格式问题,所以我认为不需要更多的信息.

再次,谢谢!

该readStream函数在读取少于完整缓冲区时终止.

但是,这只是意味着现在没有更多数据可用; 未来可能会有更多可用的东西.

在stream.Read返回零字节之前不要停止读取.
