Javascript 从节点发布'；s托管路由器到远程API（不到节点&x27；s托管API）

想要一个将Json发布到某个远程API的节点路由器吗？

今天早上我在这个问题上花了很多精力，所以我想通过提供一些全面的例子来分享这一点，以供大家参考

在每个示例中，路由器都有一个GET方法，当调用该方法时，会将其发回同一路由器。我还非常清楚地展示了如何发送和访问接收到的数据

在Node.js中，在路由器中，有时您可能需要从路由器向某个远程api发布什么

---使用

npm安装needle-save

——文件

routes/nee.js

---

var express = require('express');
var router = express.Router();
var http = require('http');

router.get('/', function (req, resp) {

    var hst = req.headers.host.split(':');
    var dat = { theGreatest: 'ChuckBerry' };
    var bdy = JSON.stringify(dat);  // you have to take care of this for yourself
    var options = { host: hst[0], port: hst[1], path: req.baseUrl, method: 'PUT'  //PUT!
        , headers: { 'Content-Type': 'application/json' }
    };

    var r = http.request(options);
    r.write(bdy);
    r.end();
    resp.sendStatus(200);
});


router.put('/', function (req, resp) { // PUT. it's a PUT not a POST
    console.log('body[\'theGreatest\']', req.body['theGreatest']); // But here you DON'T have to parse it for yourself.
                 // ^ I'm happy for that even if I am feeling the loss of symmetry.
                 // ^^ At the same this is why your life is easier in a PUT instead of a POST.
    resp.sendStatus(200);
});


module.exports = router;

---使用

npm安装请求-save

——文件

routes/req.js

---

var express = require('express');
var router = express.Router();
var http = require('http');

router.get('/', function (req, resp) {

    var hst = req.headers.host.split(':');
    var dat = { theGreatest: 'ChuckBerry' };
    var bdy = JSON.stringify(dat);  // you have to take care of this for yourself
    var options = { host: hst[0], port: hst[1], path: req.baseUrl, method: 'PUT'  //PUT!
        , headers: { 'Content-Type': 'application/json' }
    };

    var r = http.request(options);
    r.write(bdy);
    r.end();
    resp.sendStatus(200);
});


router.put('/', function (req, resp) { // PUT. it's a PUT not a POST
    console.log('body[\'theGreatest\']', req.body['theGreatest']); // But here you DON'T have to parse it for yourself.
                 // ^ I'm happy for that even if I am feeling the loss of symmetry.
                 // ^^ At the same this is why your life is easier in a PUT instead of a POST.
    resp.sendStatus(200);
});


module.exports = router;

---使用节点自己的

http.request（）

——文件

路由/nodehttp.js

---

var express = require('express');
var router = express.Router();
var http = require('http');

router.get('/', function (req, resp) {

    var hst = req.headers.host.split(':');
    var dat = { theGreatest: 'ChuckBerry' };
    var bdy = JSON.stringify(dat);  // you have to take care of this for yourself
    var options = { host: hst[0], port: hst[1], path: req.baseUrl, method: 'PUT'  //PUT!
        , headers: { 'Content-Type': 'application/json' }
    };

    var r = http.request(options);
    r.write(bdy);
    r.end();
    resp.sendStatus(200);
});


router.put('/', function (req, resp) { // PUT. it's a PUT not a POST
    console.log('body[\'theGreatest\']', req.body['theGreatest']); // But here you DON'T have to parse it for yourself.
                 // ^ I'm happy for that even if I am feeling the loss of symmetry.
                 // ^^ At the same this is why your life is easier in a PUT instead of a POST.
    resp.sendStatus(200);
});


module.exports = router;

---当您只想发布一些Json数据时，通过执行

content-type=application/Json

-----

也许是最简单的

---使用

npm install requestify-save

——文件

routes/rify.js

---

var express = require('express');
var router = express.Router();
var http = require('http');

router.get('/', function (req, resp) {

    var hst = req.headers.host.split(':');
    var dat = { theGreatest: 'ChuckBerry' };
    var bdy = JSON.stringify(dat);  // you have to take care of this for yourself
    var options = { host: hst[0], port: hst[1], path: req.baseUrl, method: 'PUT'  //PUT!
        , headers: { 'Content-Type': 'application/json' }
    };

    var r = http.request(options);
    r.write(bdy);
    r.end();
    resp.sendStatus(200);
});


router.put('/', function (req, resp) { // PUT. it's a PUT not a POST
    console.log('body[\'theGreatest\']', req.body['theGreatest']); // But here you DON'T have to parse it for yourself.
                 // ^ I'm happy for that even if I am feeling the loss of symmetry.
                 // ^^ At the same this is why your life is easier in a PUT instead of a POST.
    resp.sendStatus(200);
});


module.exports = router;

享受吧&我希望这些更全面的演示也能帮助您。

看起来不错。相当多的工作记录了不同的选项
