proxy middleware express webpack

2、针对每个entry进行单独的跨域代理配置，便于维护

安装

npm i --save-dev service-proxy-middleware

yarn add --dev service-proxy-middleware

配置

| 名称 | 类型 | 默认值 | 描述 | | ------------- | -------- | ------------- | ------------------------------------------------------------ | | filename | {String} | proxyRules.js | 代理规则配置文件名称 | | publicPath | {String} | / | webpack.devServer.publicPath 属性 | | webpackConfig | {Object} | 必传参数 | webpack配置 | | server | {Object} | undefined | webpack-dev-server对象，用于操作浏览器刷新，如果不传，代理配置文件发生改变时，不会触发浏览器刷新 | | commonProxys | {Array} | [] | 公共代理配置文件 | | realtimeLog | {Boolean} | false | 实时配置日志输出，默认为false，如果为true，则代理配置文件发生改变时，会实时更新终端输出的代理配置 |

使用

service-proxy-middleware目前支持三种类型的entry，分别是String、Array、Object，我针对这三种类型写了三个example

String类型entry

webpack.config.js

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const serviceProxyMiddleware = require('../../index');
module.exports = {
	mode: "development",
	entry: path.join(process.cwd(), 'example/demo01/src/index.js'),
	output: {
		filename: '[name].[hash].js'
	},
	plugins: [
		new HtmlWebpackPlugin({
			title: 'proxy-index.html',
			filename: 'index.html'
		}),
		new HtmlWebpackPlugin({
			title: 'proxy-app.html',
			filename: 'app.html'
		}),
	],
	devServer: {
		before(app, server) {
			app.use(serviceProxyMiddleware({
				webpackConfig: module.exports,
				server,
				// 公共代理配置文件
				commonProxys: [
					path.resolve(__dirname, '..', 'other', 'proxyRules.js')
				]
			}));
		}
	}
}

跨域代理配置文件：proxyRules.js

⚠️注意：这个跨域代理配置文件，必须放在跟entry文件的同级目录下。

module.exports = [
	{
		enable: true,
		context: [
			'/j/*'
		],
		target: 'https://movie.douban.com'
	},
	{
		enable: true,
		context: [
			'/passport'
		],
		target: 'http://news.baidu.com'
	},
	{
		enable: true,
		context: [
			'/mojiweather/**'
		],
		target: 'http://www.moji.com'
	}
]

entry文件：index.js

import axios from 'axios';
let result;
(async () => {
	try {
		result = await axios.get('/j/search_subjects?type=movie&tag=%E7%83%AD%E9%97%A8&page_limit=50&page_start=0');
		console.log('/j/search_subjects=>', result);
	} catch (e) {
		console.log(e)
	}
	
	try {
		result = await axios.get('/passport');
		console.log('/passport=>', result);
	} catch (e) {
		console.log(e);
	}
	
	try {
		result = await axios.get('/mojiweather/forecast.php');
		console.log('/mojiweather/forecast.php=>', result);
	} catch (e) {
		console.log(e)
	}
	
	try {
		result = await axios.get('/mojiweather/news.php');
		console.log('/mojiweather/news.php=>', result);
	} catch (e) {
		console.log(e)
	}
})();

运行效果：

当webpack-dev-server启动后，当我们修改proxyRules.js文件时，浏览器会实时刷新并读取最新的代理配置，立马就能验证效果，这个在我们开发阶段非常有用，我们可以通过修改target随意切换接口的请求环境（测试、灰度、线上）。

Array类型entry

webpack.config.js

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const serviceProxyMiddleware = require('../../index');
module.exports = {
	mode: "development",
	entry: [
		path.join(process.cwd(), 'example/demo01/src/index.js'),
		path.join(process.cwd(), 'example/other/index.js')
	],
	output: {
		filename: '[name].[hash].js'
	},
	plugins: [
		new HtmlWebpackPlugin({
			title: 'proxy-index.html',
			filename: 'index.html'
		}),
		new HtmlWebpackPlugin({
			title: 'proxy-app.html',
			filename: 'app.html'
		}),
	],
	devServer: {
		before(app, server) {
			app.use(serviceProxyMiddleware({ webpackConfig: module.exports, server }));
		}
	}
}

跨域代理配置文件：proxyRules.js

⚠️注意：这个跨域代理配置文件，必须放在跟entry文件的同级目录下。

module.exports = [
	{
		enable: true,
		context: [
			'/j/*'
		],

	{
		enable: true,

		target: 'http://news.baidu.com'
	},
	{
		enable: true,
		context: [
			'/mojiweather/**'

		target: 'http://www.moji.com'
	}
]

entry文件：index.js

import axios from 'axios';
let result;
(async () => {
	try {
		result = await axios.get('/j/search_subjects?type=movie&tag=%E7%83%AD%E9%97%A8&page_limit=50&page_start=0');
		console.log('/j/search_subjects=>', result);
	} catch (e) {
		console.log(e)
	}
	
	try {
		result = await axios.get('/passport');
		console.log('/passport=>', result);
	} catch (e) {
		console.log(e);
	}
	
	try {
		result = await axios.get('/mojiweather/forecast.php');
		console.log('/mojiweather/forecast.php=>', result);
	} catch (e) {

	}
