使用socket.io-client发送cookie [英] Send cookies with socket.io-client

问题描述

我正在尝试连接到网络套接字.我想通过实际的网站登录信息添加cookie，因此服务器(不我的服务器)知道我是谁(事件是特定于帐户的).

I am trying to connect to a websocket. I would like to add cookies from the actual website login, so the server (which is NOT mine), knows who I am (events are account specific).

var opts = {
   extraHeaders: {
        'Cookie': "_ga=GA1.2.17432343994.1475611967; _gat=1; __cfduid=dc232334gwdsd23434542342342342475611928"
    },
}

function socket() {
            var socket = io(websiteURL, opts);
            var patch = require('socketio-wildcard')(io.Manager); patch(socket);

            socket.on('connect', function () {
                console.log(" > [Connected]");

            });
            socket.on('*', function (data) {                
                console.log(" >>> " + data);
            });

            socket.on('disconnect', function () {
                console.log(" > [Disconnected]");
            });

}

由于我正在从网站(而不是按帐户)接收公共事件，因此连接本身可以正常工作.

The connection itself works fine, since I am receiving the public events from the website (not per-account ones).

我尝试使用node-inspector查找问题.

I tried to find the problem using node-inspector.

这是正在执行的第一个请求.似乎请求标头为空，而那里缺少cookie.

This is the first request that is being done. It seems like the request headers are empty and the cookies are missing from there.

节点检查器:

该网站在chrome中的常规用法:

Normal usage of the website in chrome:

(是的，我在节点中发送的cookie较少，只是为了查看它们是否在请求cookie中弹出)

(Yes, I am sending less cookies in node, just to see if they pop up in the request cookies)

我做错什么了吗?我将如何以正确的方式添加Cookie?

Am I doing something wrong? How would I add cookies the right way?

推荐答案

我有一个类似的问题，我认为您的选项必须为轮询"传输方法设置cookie，如下所示:

I had a similar problem, I think your options have to set the cookie for the "polling" transport method, like this:

var opts = {
    transportOptions: {
        polling: {
            extraHeaders: {
                'Cookie': '_ga=GA1.2.17432343994.1475611967; _gat=1; __cfduid=dc232334gwdsd23434542342342342475611928'
            }
        }
    }
}

我将其与以下多合一服务器-客户端示例一起使用:

I got this to work with the following all-in-one server-client example:

const express = require('express');
const http = require('http');

const app = express();
const httpServer = new http.Server(app);
const socketServer = require('socket.io')(httpServer);

const LISTEN_PORT = 4444;

socketServer.on('connection', socket => {
    const cookieString = socket.handshake.headers.cookie;
    console.log('server connection ' + (cookieString || ''));

    setInterval(() => socket.emit('ping', Date.now()), 1000);
});

let socketClient = undefined;
httpServer.listen(LISTEN_PORT, 'localhost', () => {
    console.log('web server started')

    const options = {
        transportOptions: {
            polling: {
                extraHeaders: {
                    'Cookie': 'hello=world'
                }
            }
        }
    }
    socketClient = require('socket.io-client').connect('http://localhost:'+LISTEN_PORT, options);
    socketClient.on('ping', (data) => console.log('ping ' + data));
});
