无法连接到 cpanel https 上的套接字 io 服务器

Question

我在服务器上安装了 whm 并创建了 2 个主机

1。 app.example.com 2. socket.example.com

我在 app.example.com 上收到了我的 laravel 申请我正在尝试在 socket.example.com

上创建套接字服务器

套接字服务器托管于 socket.example.com

const app = require("express")();

const fs = require("fs")
const https = require("https")
const https_server = https.createServer({
    key: fs.readFileSync('./server.key'),
    cert: fs.readFileSync('./server.cert')
},app);


const options = {
    cors : {
        origin : "*"
    }
};
const io = require("socket.io")(https_server, options);

io.on("connection", socket => { /* ... */ });

https_server.listen(8001);

客户端托管于 app.example.com

<script>
const socket = io("https://socket.example.com:8001",{
        secure: true ,
    }) ;

    socket.on("connect",() => {
        console.log("connected")
    })

    socket.on("message",( e ) => {
        console.log( e )
    })
</script>

apache 配置对于反向代理

ProxyPreserveHost On
RewriteEngine On

# Everything else forwards as HTTP to the node app.
ProxyPass / https://127.0.0.1:8001/
ProxyPassReverse / https://127.0.0.1:8001/

我可以从本地主机连接到 socket.example.com:8001，但我无法从 app.example.com

连接

错误

Access to XMLHttpRequest at 'https://socket.example.com:8001/socket.io/?EIO=3&transport=polling&t=NcjrB8N' from origin 'https://app.example.com' has been blocked by CORS policy: 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'. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.

Answer 1

这是因为 socket.example.com 和 app.example.com 共享同一个域，并且 socket.example.com 不允许跨源请求，所以当您尝试从本地主机连接时抛出错误。尝试在 socket.example.com's 虚拟主机中将本地主机列入白名单或尝试以下解决方案。

试试这个。

在您的虚拟主机文件中，将 ServerName 从 localhost 更改为 test.example.com，或者如果名称 test.example.com.

不存在，则创建如下所示的虚拟主机文件

NameVirtualHost *:80
<VirtualHost *:80>
    ServerName test.example.com
    DocumentRoot /path/to/project/doc/root
    ErrorLog "var/log/error_log"
    CustomLog "var/log/access_log" common
</VirtualHost>

并在文件底部添加下行 /etc/hosts

127.0.0.1 test.example.com

然后尝试从浏览器使用 test.example.com 访问您的本地应用程序。它应该有效。
