If you have Node.js 4.4+, take a look at <a href="https://github.com/mrsarm/reqclient" rel="nofollow">reqclient</a>, it allows you to make calls and log the requests in cURL style, so you can easily check and reproduce the calls outside the application.

Returns <a href="http://www.html5rocks.com/en/tutorials/es6/promises/" rel="nofollow">Promise</a> objects instead of pass simple callbacks, so you can handle the result in a more "fashion" way, <a href="http://odetocode.com/blogs/scott/archive/2015/09/28/chaining-promises-in-javascript.aspx" rel="nofollow">chain</a> the result easily, and handle errors in a standard way. Also removes a lot of boilerplate configurations on each request: base URL, time out, content type format, default headers, parameters and query binding in the URL, and basic cache features.

This is an example of how to initialize it, make a call and log the operation with curl style:

<pre class="lang-js prettyprint-override"><code>var RequestClient = require("reqclient").RequestClient;
var client = new RequestClient({
 baseUrl:"http://baseurl.com/api/", debugRequest:true, debugResponse:true});
client.post("client/orders", {"client": 1234, "ref_id": "A987"},{"x-token": "AFF01XX"});
</code></pre>

This will log in the console...

<pre><code>[Requesting client/orders]-&gt; -X POST http://baseurl.com/api/client/orders -d '{"client": 1234, "ref_id": "A987"}' -H '{"x-token": "AFF01XX"}' -H Content-Type:application/json
</code></pre>

And when the response is returned ...

<pre><code>[Response client/orders]&lt;- Status 200 - {"orderId": 1320934}
</code></pre>

This is an example of how to handle the response with the promise object:

<pre class="lang-js prettyprint-override"><code>client.get("reports/clients")
 .then(function(response) {
 // Do something with the result
 }).catch(console.error); // In case of error ...
</code></pre>

Of course, it can be installed with: <code>npm install reqclient</code>.

I use <a href="https://www.npmjs.com/package/node-fetch" rel="noreferrer">node-fetch</a> because it uses the familiar (if you are a web developer) <a href="https://developer.mozilla.org/en/docs/Web/API/Fetch_API" rel="noreferrer">fetch() API</a>. fetch() is the new way to make arbitrary HTTP requests from the browser.
Yes I know this is a node js question, but don't we want to reduce the number of API's developers have to memorize and understand, and improve re-useability of our javascript code? <a href="https://fetch.spec.whatwg.org/" rel="noreferrer">Fetch is a standard</a> so how about we converge on that?
The other nice thing about <code>fetch()</code> is that it returns a javascript <a href="https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Promise" rel="noreferrer">Promise</a>, so you can write async code like this:
<pre><code>let fetch = require('node-fetch');

fetch('http://localhost', {
 method: 'POST',
 headers: {'Content-Type': 'application/json'},
 body: '{}'
}).then(response =&gt; {
 return response.json();
}).catch(err =&gt; {console.log(err);});

<h3>Axios</h3>

An example (axios_example.js) using Axios in Node.js:

<pre><code>const axios = require('axios');
const express = require('express');
const app = express();
const port = process.env.PORT || 5000;

app.get('/search', function(req, res) {
 let query = req.query.queryStr;
 let url = `https://your.service.org?query=${query}`;

 axios({
 method:'get',
 url,
 auth: {
 username: 'the_username',
 password: 'the_password'
 }
 })
 .then(function (response) {
 res.send(JSON.stringify(response.data));
 })
 .catch(function (error) {
 console.log(error);
 });
});

var server = app.listen(port);
</code></pre>

Be sure in your project directory you do:

<pre><code>npm init
npm install express
npm install axios
node axios_example.js
</code></pre>

You can then test the Node.js REST API using your browser at: <code>http://localhost:5000/search?queryStr=xxxxxxxxx</code>

Similarly you can do post, such as:

<pre><code>axios({
 method: 'post',
 url: 'https://your.service.org/user/12345',
 data: {
 firstName: 'Fred',
 lastName: 'Flintstone'
 }
});
</code></pre>

<h3>SuperAgent</h3>

Similarly you can use SuperAgent.

<pre><code>superagent.get('https://your.service.org?query=xxxx')
.end((err, response) =&gt; {
 if (err) { return console.log(err); }
 res.send(JSON.stringify(response.body));
});
</code></pre>

And if you want to do basic authentication:

<pre><code>superagent.get('https://your.service.org?query=xxxx')
.auth('the_username', 'the_password')
.end((err, response) =&gt; {
 if (err) { return console.log(err); }
 res.send(JSON.stringify(response.body));
});
</code></pre>

In Node.js, other than using child process to make CURL call, is there a way to make CURL call to remote server REST API and get the return data?

I also need to set up the request header to the remote REST call, and also query string as well in GET (or POST). 

I find this one: <a href="http://blog.nodejitsu.com/jsdom-jquery-in-5-lines-on-nodejs" rel="noreferrer">http://blog.nodejitsu.com/jsdom-jquery-in-5-lines-on-nodejs</a>

but it doesn't show any way to POST query string.

How to make remote REST call inside Node.js? any CURL?

身份验证

服务器

JSON

在Node.js中，除了使用子进程进行 CURL 调用之外，还有什么方法可以对远程服务器REST API进行CURL调用并获取返回数据？我还需要设置远程REST调用的请求头，以及GET (或POST)中的查询字符串。我找到了这个：但是它没有显示任何POST查询字符串的方法。
