copied!<p>I tested your code on Firefox 4 and got the same error upon hitting send, however before that I got </p> <blockquote> <p>Firefox can't establish a connection to the server at ws://localhost:8888/.</p> </blockquote> <p>which is probably why the WebSocket object was destroyed. I suspect your handshake response is missing something, so Firefox is closing the socket.</p> <p>From the Wikipedia article on Websockets:</p> <blockquote> <p>The Sec-WebSocket-Key1 and Sec-WebSocket-Key2 fields and the eight bytes after the fields are random tokens which the server uses to construct a 16 byte token at the end of its handshake to prove that it has read the client's handshake.</p> </blockquote> <p>Your server's response does not have this special number at the bottom, So I think we need to figure out how to generate it, and include it.</p> <p><strong>EDIT: How to generate that number</strong></p> <p>Lets start with key1, key2, and the 8 bytes at the end of the handshake</p> <pre><code>key1 = "18x 6]8vM;54 *(5: { U1]8 z [ 8" key2 = "1_ tx7X d < nw 334J702) 7]o}` 0" end8 = "Tm[K T2u" </code></pre> <p>We make a number for each key by ignoring every character that is not a digit 0-9. In Python:</p> <pre><code>def numFromKey(key): return int(filter(lambda c: c in map(str,range(10)),key)) </code></pre> <p>next we divide that number by the number of spaces in the original key string, so here is a is a function that counts the spaces in a string.</p> <pre><code>def spacesIn(key): return len(filter(lambda c: c==' ',key)) </code></pre> <p>The two numbers resulting from the keys are:</p> <pre><code>pkey1 = numFromKey(key1)/spacesIn(key1) pkey2 = numFromKey(key2)/spacesIn(key2) </code></pre> <p>Now we need to concatenate the bytes of pkey1, pkey2, and end8. The processed keys need to be represented as 32 bit Big-Endian numbers. </p> <pre><code>from struct import pack catstring = pack('>L',pkey1) + pack('>L',pkey2) + end8 </code></pre> <p>Then we take the md5 hash of those bytes to get the magic number that we tack on the end of the handshake</p> <pre><code>import md5 magic = md5.new(catstring).digest() </code></pre> <p>Thats how I think it works at least</p>
