Question

要实时制作laravel应用程序，我想使用socket-io。

客户端是由离子框架编写的移动应用程序，在192.168.1.7:8100运行。

配置并运行我安装的[laravel-echo-server][1]插件io服务器。

这是运行socket io服务器的larvel echo服务器配置文件：

{
    "authHost": "http://api.pars-app.dev",
    "authEndpoint": "/broadcasting/auth",
    "clients": [
        {
            "appId": "1924bf1d59b3759d",
            "key": "keykeykey"
        }
    ],
    "database": "redis",
    "databaseConfig": {
        "redis": {},
        "sqlite": {
            "databasePath": "/database/laravel-echo-server.sqlite"
        }
    },
    "devMode": true,
    "host": null,
    "port": "3000",
    "protocol": "http",
    "socketio": {},
    "sslCertPath": "",
    "sslKeyPath": ""
}

首先，我使用此命令运行redis服务器：

redis-server --port 3001

然后使用此命令运行soketio服务器：

laravel-echo-server start

结果是这样的：

L A R A V E L  E C H O  S E R V E R

version 1.2.7

⚠ Starting server in DEV mode...

✔  Running at localhost on port 3000
✔  Channels are ready.
✔  Listening for http events...
✔  Listening for redis events...

Server ready!

这是Echo laravel js：

window.echo = new Echo({
    broadcaster: 'socket.io',
    host: 'http://192.168.1.7:3000',
    auth: {
        headers: {
            Authorization: 'bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjUsImlzcyI6Imh0dHA6XC9cL2FwaS5wYXJzLWFwcC5kZXZcL3YxXC9hdXRoXC9zaWduSW4iLCJpYXQiOjE0OTI2NzU3OTgsImV4cCI6MTQ5NTI2Nzc5OCwibmJmIjoxNDkyNjc1Nzk4LCJqdGkiOiI5OTE3YTA4OWY0MDI4NjMwOTU5NWZmYjZmODQ2MTk5ZSJ9.oOFRmxQoiLS8BJksPkf6CQSVOcDR7rPApS71S6nZO5c'
        }
    }
});

但是当我在 Chrome 浏览器中运行主应用程序时，控制台出现以下错误：

XMLHttpRequest cannot load http://192.168.1.7:3000/socket.io/?EIO=3&transport=polling&t=LkQ5Rnb. The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://192.168.1.7:8100' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

我尝试了很多解决方案来解决这个问题，例如This Answer，但问题仍在继续。

您是否尝试使用虚拟主机替换IP地址？

并像这样配置

ServerName your-domain.dev

DocumentRoot /var/www/html/your_project/public

<Directory "/var/www/html/your_project/public">
       AllowOverride all
       Header set Access-Control-Allow-Origin "*"
       Header set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT, PATCH"
       Header set Access-Control-Max-Age "1000"
       Header set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept"
</Directory>

运行SocketIO会收听并呼叫您的域名。

希望这有帮助。我已经在我的项目中使用了SocketIO。

我使用PM2运行SocketIO。
