nodejs本地代理

添加代理文件

// index.js
const port = 9000;
const proxyTable = {
    '/localProxy/url': {
        target: 'http://ip:8081',
        pathRewrite: {
            '^/localProxy/url': '/url',
        },
        'changeOrigin': true,
    },
};

const app = express();

//设置跨域访问
app.all('*', function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "*");
    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();
});

// proxy api requests
Object.keys(proxyTable).forEach(function (context) {
    let options = proxyTable[context];
    if (typeof options === 'string') {
        options = {target: options};
    }
    app.use(proxyMiddleware(options.filter || context, options));
});

app.listen(port);
