Question

上运行的node.js上有应用程序构建

以下是允许跨域请求的规则：

    app.use(function (req, res, next) {
        // Website you wish to allow to connect
        res.setHeader('Access-Control-Allow-Origin', 'http://localhost:64263');

        // Request methods you wish to allow
        res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');

        // Request headers you wish to allow
        res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');

        // Set to true if you need the website to include cookies in the requests sent
        // to the API (e.g. in case you use sessions)
        //res.setHeader('Access-Control-Allow-Credentials', true);

        // Pass to next layer of middleware
        next();
  });

我在apache（B）上配置了虚拟主机：

<VirtualHost *:80>
    ServerName  live-chat.dev

    DirectoryIndex index.html 
    DocumentRoot C:\xampp\projects\service

    Header always set Access-Control-Allow-Origin "*"

    ProxyRequests off
    ProxyPreserveHost On

    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    ProxyPass / http://localhost:3000/
    ProxyPassReverse / http://localhost:3000/
</VirtualHost>

我还有另一个使用php开发的Web应用程序（C）。问题是：当我试图直接从A向A发送ajax请求时，它没有任何错误，但是当我向B发送请求时，它返回错误：

XMLHttpRequest cannot load http://live-chat.dev/categories. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:64263' is therefore not allowed access.

Apache proxy node.js No'Access-Control-Allow-Origin'
