The <a href="http://nodejs.org/api/http.html"><code>http</code></a> module that you use to run servers is also used to make remote requests.

Here's the example in their docs:

<pre><code>var http = require("http");

var options = {
 host: 'www.google.com',
 port: 80,
 path: '/upload',
 method: 'POST'
};

var req = http.request(options, function(res) {
 console.log('STATUS: ' + res.statusCode);
 console.log('HEADERS: ' + JSON.stringify(res.headers));
 res.setEncoding('utf8');
 res.on('data', function (chunk) {
 console.log('BODY: ' + chunk);
 });
});

req.on('error', function(e) {
 console.log('problem with request: ' + e.message);
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

blocks|key|829181|text|上面的例子可以工作，但不能真正处理真实世界的例子(例如，当你处理多个块中的数据时。您需要确保的一件事是，您有一个'on+chunk‘处理程序将数据推送到一个数组中(在JS中这是最快的方式)和一个'on+end’处理程序将它们连接在一起，以便您可以返回它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|829182|当您正在处理大请求(5000%2B行)并且服务器向您发送大量数据时，这一点尤其必要。|829183|下面是我的一个程序(Coffeescript)中的一个示例：https://gist.github.com/1105888|offset|length|829184|entityMap|0|LINK|mutability|MUTABLE|url|https://gist.github.com/1105888^0|0|0|U|V|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@$F|S|G|T|1|U]]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

The above examples work but don't go so far as to really deal with a real world example (i.e. when you process data coming in multiple chunks. One thing you need to make sure of is that you have an 'on chunk' handler that push's the data into an array (fastest way to do this in JS) and an 'on end' handler that joins them all together so you can return it.

This is especially necessary when you're working with big requests (5000+ lines) and the server sends a bunch of data at you.

Step 1: <code>$npm i -S curlrequest</code>

Step 2: In your node file

<pre><code>let curl = require('curlrequest')
let options = {} // url, method, data, timeout,data, etc can be passed as options 
curl.request(options,(err,response)=&gt;{
// err is the error returned from the api

I used command prompt to do so.

<pre><code>sudo curl --URL http://&lt;username&gt;.cloudant.com/&lt;database_name&gt; --user &lt;api_key&gt;:&lt;pass_key&gt; -X POST -H "Content-Type:application/json" --data '{"id":"123","type":"987"}'
</code></pre>

Command prompt will show the problems - wrong username/pass; bad request etc.

--URL database/server location (I used simple free Cloudant DB)
--user is the authentication part username:pass I entered through API pass
-X defines what command to call (PUT,GET,POST,DELETE)
-H content type - Cloudant is about document database, where JSON is used
--data content itself sorted as JSON

I'm looking to use information from an HTTP request using Node.js (i.e. call a remote web service and echo the response to the client).

In PHP I would have used cURL to do this. What is the best practice in Node?

cURL equivalent in Node.js?

云数据库

身份验证

数据库

服务器

物联网

Python

JSON

我希望使用来自Node.js的超文本传输协议请求的信息(例如，调用远程web服务并将响应回送到客户端)。在PHP中，我会使用cURL来做这件事。Node中的最佳实践是什么？
