简介
一个轻松的配置代理服务器的中间件,让Node.js代理变得简单
url路径
foo://example.com:8042/over/there?name=ferret#nose
\_/ \______________/\_________/ \_________/ \__/
| | | | |
scheme authority path query fragment
基本使用
var express = require('express');
var proxy = require('http-proxy-middleware');
var app = express();
app.use(
'/api',
proxy({ target: 'http://www.example.org', changeOrigin: true })
);
app.listen(3000);
两种形式
var apiProxy = proxy('/api', { target: 'http://www.example.org' });
//同样效果
var apiProxy = proxy('http://www.example.org/api');
配置
var options = {
target: 'http://www.example.org', // 目标
changeOrigin: true, // 虚拟站点必须
ws: true, // 代理websocket
pathRewrite: {
'^/api/old-path': '/api/new-path', // 重写路径
},
router: {
// when request.headers.host == 'dev.localhost:3000',
// override target 'http://www.example.org' to 'http://localhost:8000'
'dev.localhost:3000': 'http://localhost:8000'
}
};
实际使用
const express = require("express");
const next = require("next");
const dev = process.env.NODE_ENV !== "production"; //判断是否是开发环境
const app = next({ dev });
const handle = app.getRequestHandler();
const compression = require("compression");
const port = parseInt(process.env.PORT, 10) || 6776;
const proxy = require("http-proxy-middleware");
const proxyOption = {
target: "http://127.0.0.1:6688",
pathRewrite: {
"^/api/": "/" // 重写请求，api/解析为/
},
changeOrigoin: true
};
app
.prepare()
.then(() => {
const server = express();
if (dev) {
server.use("/api/*", proxy(proxyOption));
}
if (!dev) {
server.use(compression()); //gzip
}
server.get("/", (req, res) => app.render(req, res, "/home"));
server.get("/home", (req, res) => app.render(req, res, "/home"));
server.get("/books", (req, res) => app.render(req, res, "/books"));
server.get("/articles", (req, res) => app.render(req, res, "/articles"));
server.get("/login", (req, res) => app.render(req, res, "/login"));
server.get("/markdown", (req, res) => app.render(req, res, "/markdown"));
server.get("/books", (req, res) => app.render(req, res, "/books"));
server.get("/write", (req, res) => app.render(req, res, "/write"));
server.get("/book/:currentBookId", (req, res) =>
app.render(req, res, "/book/[currentBookId]", { currentBookId: req.params.currentBookId })
);
server.get("/article/:curArticleId", (req, res) =>
app.render(req, res, "/article/[curArticleId]", { curArticleId: req.params.curArticleId })
);
server.all("*", (req, res) => handle(req, res));
server.listen(port, err => {
if (err) throw err;
else console.log(`http start at ===> http://localhost:${port}`);
});
})
.catch(ex => {
console.error(ex.stack);
process.exit(1);
});
