Construct GET Request for SslStream

Question

I apologise if this is a bit dim but I want to send something like this over an sslstream to a server that I have acquired a secure socket connection to...

GET /F5Check/qpi/1 HTTP/1.1
Host: *****.com
Connection: keep-alive
Cache-Control: max-age=0
User-Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.52 Safari/536.5
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

I tried using a string builder

var sb = new StringBuilder();
sb.AppendLine("GET /F5Check/qpi/1 HTTP/1.1");
sb.AppendLine(string.Format("Host: {0}", host));
sb.AppendLine("Connection: keep-alive");
sb.AppendLine("User-Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.52 Safari/536.5");
sb.AppendLine("Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
sb.AppendLine("Accept-Encoding: gzip,deflate,sdch");
sb.AppendLine("Accept-Language: en-US,en;q=0.8");
sb.AppendLine("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3");

and then doing this

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

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

where sb is the stringbuilder object!

I am simply not getting any response from the server when I try to read from the stream so clearly the server can't make any sense of my dumbass request!

I know I could use variations of webrequest to do the same thing but there is a specific reason why I am trying to do this...

Basically I need to know what to encode for sending so that I can effect a get request?

Answer 1

A Shot in the dark:

Try setting the request's header Connection to "close".

Answer 2

One thing you seem to be missing is the blank line at the end of the request. The HTTP specification requires a blank line to separate the header fields from the message body, or to signify the end of a GET request.

As it stands, the server doesn't know your request is finished so it would be waiting for the next line. Adding an extra sb.AppendLine() should fix that.

Answer 3

I second the needing an extra line break according to HTTP standards. Simply expanding on what Tim had, here's some source code. I went ahead and used the SslStream class for connecting, I'm assuming that's what you did as well. I tested this against Google's HTTPS site, and got back a response. Hope this is enough to get you back on track.

NOTE : I changed the UA String because our proxy for some reason here hated that one. I don't believe that to be your problem, but it was an issue for me.

static void Main(string[] args)
    {

        string host = "encrypted.google.com";

        // Connect socket
        TcpClient client = new TcpClient(host,443);
        NetworkStream stream = client.GetStream();

        // Wrap in SSL stream
        SslStream sslStream = new SslStream(stream);
        sslStream.AuthenticateAsClient(host);

        //Build request
        var sb = new StringBuilder();

        sb.AppendLine("GET / HTTP/1.1");
        sb.AppendLine(string.Format("Host: {0}", host));
        sb.AppendLine("Connection: keep-alive");
        sb.AppendLine("User-Agent: CSharp");
        sb.AppendLine("Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
        sb.AppendLine("Accept-Encoding: gzip,deflate,sdch");
        sb.AppendLine("Accept-Language: en-US,en;q=0.8");
        sb.AppendLine("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3");
        sb.AppendLine();

        //Go go go!
        byte[] headerBytes = Encoding.UTF8.GetBytes(sb.ToString());
        sslStream.Write(headerBytes, 0, headerBytes.Length);
        sslStream.Flush();


        //Get a place to put it
        byte[] buffer = new byte[2048];
        int bytes;

        //Answer
        do
        {
            bytes = sslStream.Read(buffer, 0, buffer.Length);
            Console.Write(Encoding.UTF8.GetString(buffer, 0, bytes));
        } while (bytes != 0);

        //And done
        client.Close();
        Console.ReadKey();


    }
