Question

我正在使用socket.io 1.4.8和firefox 48.我有一个在chrome中工作正常的示例代码：

// Server
var express = require('express');
var app = express(); var fs = require('fs');
var option = {
    key: fs.readFileSync('key.pem'),
    cert: fs.readFileSync('cert.pem')
};
var https = require('https').createServer(options, app).listen(process.env.PORT || 3000);
var io = require('socket.io')(https);

io.on('connection', function(socket) {
    socket.on('login', function(username) {
        console.log('[login]', username);
    };
}

// Client
var socket = io('https://127.0.0.1:3000');
var username = 'test';
socket.emit('login', username);

但是当我在firefox中运行时，我得到了一个Error: xhr poll error.这是来自客户端的日志：

socket.io-client:url "parse https://127.0.0.1:3000" +0ms
socket.io-client "new io instance for https://127.0.0.1:3000" +3ms

我该如何解决此错误？感谢。

对我来说，原因是网站的自签名证书不受Firefox的信任。转到套接字URL，您应该看到一个对话框，将不受信任的站点添加到例外。

无法在FireFox中与socket.io建立连接（xhr轮询错误）
