Javascript Heroku-Socket.IO客户端始终连接到本地主机
我正在尝试将Node.js、Express.js、Socket.IO和基于React的应用程序部署到Heroku上 但是在客户端,socket.io-client似乎总是连接到localhost,即使我在连接时从未指定过localhost 我在浏览器控制台中遇到此错误:Javascript Heroku-Socket.IO客户端始终连接到本地主机,javascript,node.js,heroku,socket.io,Javascript,Node.js,Heroku,Socket.io,我正在尝试将Node.js、Express.js、Socket.IO和基于React的应用程序部署到Heroku上 但是在客户端,socket.io-client似乎总是连接到localhost,即使我在连接时从未指定过localhost 我在浏览器控制台中遇到此错误: bundle.js:208 Mixed Content: The page at 'https://test.herokuapp.com/#/test?_k=v7l28t' was loaded over HTTPS, but
bundle.js:208 Mixed Content: The page at 'https://test.herokuapp.com/#/test?_k=v7l28t' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://localhost:3000/socket.io/?EIO=3&transport=polling&t=LLobEYP'. This request has been blocked; the content must be served over HTTPS.
如果我尝试在http上打开它,则会出现连接被拒绝错误:
bundle.js:208 GET http://localhost:3000/socket.io/?EIO=3&transport=polling&t=LLpAsLm net::ERR_CONNECTION_REFUSED
以下是我的服务器套接字的外观:
var express = require('express');
var app = express();
var server = http.createServer(app);
var io = require('socket.io')(server);
server.listen(port);
io.on('connection', function(socket) {
socket.on('news', function(message) {
console.log("Responding with news");
io.sockets.emit('news', 'news');
});
});
以下是客户端代码:
var io = require('socket.io-client');
var socket = io.connect();
socket.on('connect', function() {
console.log('connected to server');
socket.emit('news', 'news');
});

如果我在这里做错了什么,请告诉我。感谢您的帮助:)您的网站在https上运行,但套接字在http上运行。为初始连接使用安全的URL,即使用http://“而不是
”https://“
或者打开您的网站(不带ssl)如果我使用以下客户端,这对我有效:
const socketURL =
process.env.NODE_ENV === 'production'
? window.location.hostname
: 'https://localhost:5000';
const socket = io.connect(socketURL, {secure: true});
你能把你的
包放上去吗?我相信可能有一个脚本调用localhost serversure。添加了相同的。打开站点的http版本,http://test.herokuapp.com
即使套接字尝试连接本地主机,我也会收到一个连接被拒绝的错误:bundle.js:208 get net::ERR\u connection\u refused即使我在http上打开它,它仍然指向localhost:3000,我收到这个错误:net::ERR\u connection\u refused您可能在某个地方得到了硬编码的url,检查项目中是否有任何其他io.connect调用。至少,为了测试目的,要显式地编写url
const socketURL =
process.env.NODE_ENV === 'production'
? window.location.hostname
: 'https://localhost:5000';
const socket = io.connect(socketURL, {secure: true});
