(Mono C#) Demonstrates KeepSessionLog and SessionLogThe Chilkat Socket component provides properties for keeping a session log making it possible to see the exact bytes received and sent on a TCP/IP or SSL/TLS connection. To enable session logging, set the KeepSessionLog property = true. The SessionLogEncoding property controls how binary, non-printable bytes are represented in the log. There are two possible settings: Possible values are "esc" and "hex". The default value is "esc". When set to "hex", the bytes are encoded as a hexidecimalized string. The "esc" encoding is a C-string like encoding, and is more compact than hex if most of the data to be logged is text. Printable us-ascii chars are unmodified. Common "C" control chars are represented as "\r", "\n", "\t", etc. Non-printable and byte values greater than 0x80 are escaped using a backslash and hex encoding: \xHH. Certain printable chars are backslashed: SPACE, double-quote, single-quote, etc.
// This example assumes the Chilkat Socket API to have been previously unlocked. // See Socket Unlock Sample for sample code. Chilkat.Socket socket = new Chilkat.Socket(); // Enable session logging: socket.KeepSessionLog = true; socket.SessionLogEncoding = "esc"; bool tls = true; int maxWaitMillisec = 20000; bool success = socket.Connect("www.chilkatsoft.com",443,tls,maxWaitMillisec); if (success != true) { Debug.WriteLine(socket.LastErrorText); return; } // Send a GET start line to the web server.. success = socket.SendString("GET /abc123.abc123 HTTP/1.1\r\n"); if (success != true) { Debug.WriteLine(socket.LastErrorText); return; } // Send some bytes that will cause an error... Chilkat.BinData binData = new Chilkat.BinData(); binData.AppendEncoded("01020304","hex"); success = socket.SendBd(binData); // Read the response up to the first double CRLF: string httpHeader = socket.ReceiveUntilMatch("\r\n\r\n"); if (socket.LastMethodSuccess != true) { Debug.WriteLine(socket.LastErrorText); return; } // Close the connection with the server // Wait a max of 20 seconds (20000 millsec) socket.Close(20000); // Display the session log: Debug.WriteLine(socket.SessionLog); // The Session log will show the exact bytes sent and received. // In this case, the session log shows: // SendString: GET\x20/abc123.abc123\x20HTTP/1.1\r\n // // SendBytes: \x01\x02\x03\x04 // ReceiveUntilMatch: HTTP/1.1\x20400\x20Bad\x20Request\r\n // Content-Type:\x20text/html;\x20charset=us-ascii\r\n // Server:\x20Microsoft-HTTPAPI/2.0\r\n // Date:\x20Thu,\x2027\x20Oct\x202016\x2013:16:02\x20GMT\r\n // Connection:\x20close\r\n // Content-Length:\x20339\r\n // \r\n // <!DOCTYPE\x20HTML\x20PUBLIC\x20\"-//W3C//DTD\x20HTML\x204.01//EN\"\"http://www.w // 3.org/TR/html4/strict.dtd\">\r\n // <HTML><HEAD><TITLE>Bad\x20Request</TITLE>\r\n // <META\x20HTTP-EQUIV=\"Content-Type\"\x20Content=\"text/html;\x20charset=us-ascii // \"></HEAD>\r\n // <BODY><h2>Bad\x20Request\x20-\x20Invalid\x20Header</h2>\r\n // <hr><p>HTTP\x20Error\x20400.\x20The\x20request\x20has\x20an\x20invalid\x20header // \x20name.</p>\r\n // </BODY></HTML>\r\n // |
