react http-proxy-middleware配置代理(前端代码以及用于自测的服务器代码)

官方文档.
src/setupProxy.js源代码

const {
    
     createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function (app) {
    
    
//http://localhost:4568/ 这是服务器域名
    app.use(
        '/api',
        createProxyMiddleware({
    
    
            target: 'http://localhost:4568/',
            changeOrigin: true,
            pathRewrite: {
    
    
                '^/api': '',
            },
        })
    );
};

请求代码demo

  axios.get('http://localhost:3000/api/v1/device')
            .then(function (response) {
    
    
                console.log(response);
            })
            .catch(function (error) {
    
    
                console.log(error);
            });

服务器代码(只是搭建一个服务器测试我的前端服务器代理配置)

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

app.get("/", (req, res) => {
    
    
    res.send("Hello world");
});
app.all("*", function (req, res, next) {
    
    
    // res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "X-Requested-With");
    res.header("Access-Control-Allow-Methods", "PUT,POST,GET,DELETE,OPTIONS");
    res.header("X-Powered-By", " 3.2.1");
    res.header("Content-Type", "application/json;charset=utf-8");
    next();
});

app.listen(4568, (req, res) => {
    
    
    console.log(res);
    console.log("Server is running at http://localhost:4568");
});
