"proxy": "http://localhost:3001" 在我的包.json express服务器在这个端口(3001)上运行,但每次我接到react的请求时,它都在运行react应用程序的3000端口上运行

包.json

{
  "name": "client",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "antd": "^3.10.2",
    "axios": "^0.18.0",

  ]
}

const proxy = require('http-proxy-middleware');

module.exports = function(app) {
  app.use(proxy('/api/*', { target: 'http://localhost:3001' }));
};

"proxy": {
"/services": {
  "target": "http://localhost:3001",
  "changeOrigin": true,
  "pathRewrite": {
    "^/services": ""
  }
}

}

npm重新开始

您可以在索引.js

const PORT = 3001;

和使用

"proxy": { "/*": { "target": "http://localhost:3001" } }

在客户端包.json

对于http代理中间件: 安装程序包。创建一个名为设置代理.js

const proxy = require('http-proxy-middleware');

module.exports = function(app) {
  app.use(proxy('/', { target: 'http://localhost:3001' }));
};

记住从客户端删除旧的代理脚本代码包.json.

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

module.exports = function(app) {
  app.use('/console/api', createProxyMiddleware({ 
    target: 'http://localhost:8080/', 
    changeOrigin: true, 
    pathRewrite: {'^/console/api' : ''} 
  }));
};

换句话说, proxy 应替换为 createProxyMiddleware
