1 react porxy 只代理一个
修改package.json文件 新增
"proxy":"http://172.19.5.35:9536",
"name": "wangguan",
"version": "0.1.0",
"private": true,
"proxy":"http://172.19.5.35:9536",
2 react porxy 代理多个
"name": "wangguan",
"version": "0.1.0",
"private": true,
"proxy":{
"/api": {
"target": "http://172.19.5.35:9536",
"ws": true
},
"/apc": {
"target": "http://179.19.5.35:9536",
"ws": true
}
},
报错:提示只支持string类型,不支持object "proxy" in package.json must be a string.
解决方案 新版react16.6中 create-react-app升级版(webpack4.0) 配置http请求跨域问题 但在最新的create-react-app v2升级版(webpack4.0)中，如果proxy不是字符串，并不能这么在 package.json直接配置，会报错！ 通过查阅create-react-app的官方文档https://facebook.github.io/create-react-app/docs/getting-started，找到了如下的解决方案。
1）：安装http-proxy-middleware管理包，cnpm http-proxy-middleware --save
2）：在项目目录src/下新建setupProxy.js文件，然后写入如下代码:
const proxy = require(‘http-proxy-middleware‘);
module.exports = function(app) {
app.use(proxy(‘/api‘, {
target: ‘http://192.168.1.144:8181‘ ,
secure: false,
changeOrigin: true,
pathRewrite: {
"^/api": "/"
},
// cookieDomainRewrite: "http://localhost:3000"
}));
};

Note: this feature is available with [email protected] and higher.
If the proxy option is not flexible enough for you, you can get direct access to the Express app instance and hook up your own proxy middleware.
You can use this feature in conjunction with the proxy property in package.json, but it is recommended you consolidate all of your logic into src/setupProxy.js.
First, install http-proxy-middleware using npm or Yarn:
$ npm install http-proxy-middleware --save
$ # or
$ yarn add http-proxy-middleware
Next, create src/setupProxy.js and place the following contents in it:
const proxy = require('http-proxy-middleware');
module.exports = function(app) {
// ...
};
You can now register proxies as you wish! Here's an example using the above http-proxy-middleware:
const proxy = require('http-proxy-middleware');
module.exports = function(app) {
app.use(proxy('/api', { target: 'http://localhost:5000/' }));
};
我的src/setupProxy.js
const proxy = require('http-proxy-middleware');
module.exports = function(app) {
// ...You can now register proxies as you wish!
app.use(proxy('/api', {
target: 'http://172.19.5.35:9536',
secure: false,
changeOrigin: true,
pathRewrite: {
"^/api": "/"
},
}));
app.use(proxy('/apc', {
target: 'http://172.19.5.34:9531',
secure: false,
changeOrigin: true,
pathRewrite: {
"^/apc": "/"
},
}));
//app.use(proxy('/apc', { target: 'http://172.19.5.34:9531' }));
};
相关代码 axios拦截设置 request.js文件
import axios from 'axios'
import {Toast} from 'antd-mobile';
//创建axios实例
const service = axios.create({
baseURL: process.env.BASE_API, // api的base_url
timeout: 200000, // 请求超时时间
withCredentials: true // 选项表明了是否是跨域请求
})
service.interceptors.request.use(config => {
Toast.loading('加载中',1) // loading组件，显示文字加载中，自动关闭延时1s
console.log('request go');
return config;
}, err => {
console.log('请求失败')
return Promise.reject(err)
})
//拦截响应
service.interceptors.response.use(config => {
Toast.hide() // 销毁Toast组件
console.log('response get')
return config;
}, err => {
console.log('响应失败')
return Promise.reject(err)
})
// respone拦截器
service.interceptors.response.use(
response => {
/**
* code为非000000是抛错 可结合自己业务进行修改
*/
const res = response.data
if (res.code !== '000000') {
console.log("response",res)
res.code = res.data.code
res.message = res.response.data.msg
Toast.info(res.code+res.message, 2);
return Promise.reject('error')

页面调用
import React, { Component } from 'react';

// using ES6 modules
import { BrowserRouter, Route, Link } from 'react-router-dom'

// 第二个接口
let ownerId =data.ownerId

本地mock数据
- .json文件放在
- ajax请求
axios.get('/mock/list.json').then((res)=>{
const data = res.data;
console.log(data);
})
