当通过WebSockets连接到socket.io时如何发送cookie？ [英] How to send cookies when connecting to socket.io via WebSockets?

问题描述

有没有办法轻松传递验证cookie当握手WebSocket连接到socket.io？我现在必须单独做，像这样：

Is there a way to easily pass an authentication cookie when handshaking a WebSocket connection to socket.io? I currently have to do it separately, like so:

socket = new io.Socket(document.location.hostname);
socket.addEvent("connect", function()
{
    // Send PHP session ID, which will be used to authenticate
    var sessid = readCookie("PHPSESSID");
    this.send("{'action':'authenticate','sessionid':'"+sessid+"'}");
});

推荐答案

WebSockets支持Cookie，因为它们基于HTTP，但是通过Socket.IO的源代码的快速浏览显示不支持这个内置。

WebSockets do have support for cookies since they are based on HTTP, but a quick browse through the source of Socket.IO revealed that there is no support for this built in.

所以直接使用cookies不是一个可行的解决方案case，同样，因为你使用Socket.IO，它不能保证用户实际上通过WebSocket连接。

So using cookies directly is not a feasible solution in this case, also, since you're using Socket.IO, it's not guaranteed that users will actually connect via a WebSocket.

如果连接使用闪存插槽，它真的很难使Flash发送浏览器的cookie而不是自己的设置，所以即使你会直接发送一个cookie，它不会设置在浏览器中的情况下，一个烧瓶插座连接。

In the case that a connection uses a flash socket, it's really hard to make Flash send the Browser's cookies instead of it's own set, so even if you would send a cookie directly, it wouldn't get set in the Browser in case of a flask socket connection.

目前不支持Socket.IO内置的内存，所以f​​lash套接字只会失败。

Currently there's no support for this built into Socket.IO, so flash sockets will just fail.

你可以在< a href =https://github.com/LearnBoost/Socket.IO-node/issues#issue/101>此问题，这里有一个关于 Flash Cookie问题。

You can read about that in this issue, and here's a question about the flash cookie problem.

最佳解决方案仍然是您自己协议的一部分。

Best solution is still to make it part of your own protocol.
