'Sec-WebSocket-Accept' header is missing in Chrome 17 - google-chrome

Question

Edit:
I tried this phpwebsocket: http://www.wilky.it/Shared/phpwebsocket.zip and it works in Firefox, but my question still remains: how do I get websockets to work with a php server in Chrome 17?
I'm following the tutorial here: http://net.tutsplus.com/tutorials/javascript-ajax/start-using-html5-websockets-today/
It appears as though the client connects, and then immediately disconnects. I noticed this error in the console:
Error during WebSocket handshake: 'Sec-WebSocket-Accept' header is missing
I'm trying it in Chrome 17.0.963.56 on my WAMP localhost with the php_sockets extension enabled.
I saw mentioned somewhere that Chrome had changed what it supported, but it didn't go in depth on how to fix it. I was hoping someone could step me through it. (I'm brand new to websockets).
Server:
{PATH}>php startDaemon.php

Answer 1

I have the same problem (and I do not seem to be able to post a comment here, so I post a reply).
Actually, I just downloaded and tested phpwebsocket.
On safari 5.1.4, it works just fine.
On Chrome 17, I got the same error in the script log console:
Error during WebSocket handshake: 'Sec-WebSocket-Accept' header is missing
So, in websocket.class.php, I added to the header returned by server:
$accept = base64_encode(SHA1($key."258EAFA5-E914-47DA-95CA-C5AB0DC85B11"));
And I get the error:
Error during WebSocket handshake: Sec-WebSocket-Accept mismatch
Now, the header received by the server is:
GET /websocket/server.php HTTP/1.1
Upgrade: websocket
Connection: Upgrade
Host: localhost:12345
Origin: http://localhost:8888
Sec-WebSocket-Key: OqMJI0t/cOl6d6JNE+Op0g==
Sec-WebSocket-Version: 13
And the header sent back by the server is:
HTTP/1.1 101 WebSocket Protocol Handshake
Upgrade: WebSocket
Connection: Upgrade
Sec-WebSocket-Origin: http://localhost:8888
Sec-WebSocket-Location: ws://localhost:12345/websocket/server.php
Sec-WebSocket-Accept: ZjY5ODliNTViYzJlOTNkMjk4OTg3Y2U2NjQ3MTBlZjZiNzliYzk4Yg==
The Sec-WebSocket-Accept seems good, but still there is a mismatch error. Do you see a mistake somewhere? Maybe the protocol has changed to calculate the Sec-WebSocket-Accept, but I don't find it... Thanks for your help!
Edit: Here seems to be the solution (for me, at least): adding the parameter true to the SHA1 function, as found in files given in this issue thread. So, the Sec-WebSocket-Accept must be found like this:
$accept = base64_encode(SHA1($key."258EAFA5-E914-47DA-95CA-C5AB0DC85B11", true));
And, Sec-WebSocket-Key1 and Sec-WebSocket-Key2 does not seem to be present anymore in the client request, instead, $key must be extracted from the header: "Sec-WebSocket-Key".
New issue: It seems too that even if the web socket connection now works on the handshake, it disconnects when the first message is sent.

I noticed that in the console of Chrome 19:
A server must not mask any frames that it sends to the client.
Maybe this is the problem. It disconnects as soon as a message is sent. It works fine in Firefox.
I fixed this websocket problem and it works in chrome now.
First I used:
Then I used the encode function from:
https://github.com/lemmingzshadow/php-websocket
I fixed the replaced the encode function with the one in the connection.php file in lemmingzshadow’s github and it started working. The function is called: hybi10Encode in the \server\lib\WebSocket\connection.php file.
change this parameter in the function encode: $masked = true to $masked = false

Answer 3

An EASY way to fix is add Sec-WebSocket-Accept information when do_handshake, code as below:
list($resource,$host,$origin,$key) = $this->getheaders($buffer);
$accept = base64_encode(SHA1($key."258EAFA5-E914-47DA-95CA-C5AB0DC85B11", true));
$upgrade = "HTTP/1.1 101 Web Socket Protocol Handshake\r\n" .
"Upgrade: WebSocket\r\n" .
"Connection: Upgrade\r\n" .
"WebSocket-Origin: {$origin}\r\n" .
"WebSocket-Location: ws://{$host}{$resource}\r\n".
"Sec-WebSocket-Accept: " . $accept . "\r\n\r\n";
$this->handshakes[$socket_index] = true;
socket_write($socket,$upgrade,strlen($upgrade));
where,
$accept = base64_encode(SHA1($key."258EAFA5-E914-47DA-95CA-C5AB0DC85B11", true));
$key is Sec-WebSocket-Key got from $buffer, you can print_r($buffer) to have a look.
Hope this can solve your problem..
