将FROM Node的托管路由器发布到远程API(而不是TO节点的托管API)

想要一个将Json POST到某个远程API的节点路由器吗?

今天早上我在这个问题上付出了很多努力,所以我想通过提供一些全面的例子来分享这个问题。

在每个示例中,路由器都有一个GET方法,当被调用时,POSTS返回到同一个路由器。我还非常清楚地展示了如何发送以及如何访问接收的数据。

在Node.js中,在路由器中,您可能有时会从路由器发布到某个远程api。

---使用npm install needle -save ---文件routes/nee.js ---

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

router.get('/', function (req, resp) {
    var dat = { theGreatest: 'ChuckBerry' };
    var lookbackURL = 'http://' + req.headers.host + req.baseUrl;
    needle.post(lookbackURL, dat, { json: true });
    resp.redirect('/');
});


router.post('/', function (req, resp, next) {
    console.log('body.theGreatest', req.body.theGreatest);
    resp.sendStatus(200);
});


module.exports = router;

---使用npm install request -save ---文件routes/req.js ---

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

router.get('/', function (req, resp) {
    var dat = { theGreatest: 'ChuckBerry' };
    var lookbackURL = 'http://' + req.headers.host + req.baseUrl;
    request.post(lookbackURL, { json: dat });
    resp.redirect('/');
});


router.post('/', function (req, resp, next) {
    console.log('body.theGreatest', req.body.theGreatest);
    resp.sendStatus(200);
});


module.exports = router;

---使用Node自己的http.request() - 文件routes/nodehttp.js ---

---当你只想发布一些Json数据时,通过改为content-type=application/json -----

的PUT来简化你的生活
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;

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 requestify = require('requestify');

router.get('/', function (req, resp) {
    var lookbackURL = 'http://' + req.headers.host + req.baseUrl;
    requestify.post(lookbackURL, {
        theGreatest: 'ChuckBerry'
    })
    .then(function (res) {
        //res.getBody(); // JSON parsed or XML object
        //res.body; // or get the raw
        res.redirect('/');
    });
});


router.post('/', function (req, resp, next) {
    console.log('body.theGreatest', req.body.theGreatest);
    resp.sendStatus(200);
});


module.exports = router;

享受&我希望这些更全面的演示能够帮助你。

看起来不错。记录不同的选项需要相当多的努力。
