Shouldn’t local requests be localhost? Does Apache's proxy return a 30x jump? If so, the result is still a cross-domain request. If nginx is used to set the proxy, a 30x jump will not be returned.

It is recommended to consider using nginx to set up a proxy. Please refer to:

https://zhuanlan.zhihu.com/p/...

For your reference, the following is a proxy suitable for setting that I developed in dev, based on vue-cli, index.js in the config directory

// see http://vuejs-templates.github.io/webpack for documentation.
var path = require('path')

module.exports = {

    // Gzip off by default as many popular static hosts such as
    // Surge or Netlify already gzip all static assets for you.
    // Before setting to `true`, make sure to:
    // npm install --save-dev compression-webpack-plugin
    productionGzip: false,
    productionGzipExtensions: ['js', 'css']
  },

cors cross-domain, by the way, you need to configure p3p to make IE support cross-domain cookies
