javascript - front-end cross-domain issues

Question

If the backend interface is set to restrict domain name access, can I request data by pretending to be the other party's domain name or IP through node or ajax?

Answer 1

You can configure a reverse proxy through niginx to solve cross-domain problems

Answer 2

In this case, ajax’s jsonp will not work. You can forward it through node middleware

middleware: [ // 请求代理，按需设置
            proxy('/api', {
                target: 'http://op.juhe.cn', // 目标地址
                changeOrigin: true,
                ws: true, //websocket
                pathRewrite: {
                    '^/api': '' //重写地址
                }
            })
        ]
