nodejs實現請求代理

 

 

一般咱們經常使用的請求方法只有GET、POST、PUT和DELETE，因此在此只介紹這四種和文件上傳的代理方式

在此咱們使用request.js第三方模塊實現

 

GET（DELETE同GET，將request方法改成DELETE便可）

    const request = require('request');
    const url = require('url');

    test: function (req, res, next) {
        let curl = url.parse(req.url);
        let search= curl.search;
        curl = "http:/localhost:8080/api/get"+search;

        try {
            req.pipe(request({
                method: 'GET',
                uri: curl
            })).pipe(res);

        } catch (e) {
            next(e);
        }
    }

　　

POST（PUT同POST，將request方法改成put便可）

    const request = require('request');
    const url = require('url');

    test: function (req, res, next) {
        let curl= url.parse(req.url);
        let search= curl.search;
        curl = "http://localhost:8080/api/post"+search;

        let body = req.body;
        try {
            request.post({
                uri: curl,
                form: body
            }).pipe(res);

        } catch (e) {
            next(e);
        }
    }

　　

代理文件上傳

    const request = require('request');
    const url = require('url');

    upload: function (req, res, next) {
        let curl= url.parse(req.url);
        let search= curl.search;
        curl = "http://localhost:8080/api/upload"+search;

        try {
            req.pipe(request({
                method: 'POST',
                uri: curl
            })).pipe(res);

        } catch (e) {
            next(e);
        }
    }
