Introduction

http-proxy-404mock 是一个基于http-proxy-middleware 开发的node代理服务器

Http-proxy-404 is a node proxy server based on http-proxy-middleware

你可以用它做什么呢?

What can you do with it?

你可以配置一堆不同环境的接口服务地址

You can configure a bunch of interface service addresses for different environments.

它会自动嗅探接口在当前配置的服务器地址中 请求的response的状态是否为404,如果请求的状态是404,它会往下一个地址中继续请求,直至成功

It will automatically sniff the interface to request the response status in the currently configured server address is 404,If the status of the request is 404, it will continue the request to the next address until it succeeds

Install

$ npm install http-proxy-404 --save-dev

or

$ yarn add http-proxy-404 -D

Usage

step1: create serve.js

const Proxy404 = require('http-proxy-404')

new Proxy404({
  port: 8081,
  apiReg: '/api*',
  targetList: [
    'target host1',
    'target host2',
    'target host3'
  ],
  '404func': function(res) {
    if(!res.response) {
      return true
    }
  }
})

step2: Configuring webpack

proxy: {
    '/': {
      target: "http://x.x.x.x:port", // Please fill in the proxy service address output by http-proxy-404
      ws: false,
      changeOrigin: true,
    }
  }
