如何在 Node.js 中进行远程 REST 调用？任何卷曲？

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

提问by murvinlai

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

在Node.js 中，除了使用子进程进行CURL调用之外，有没有办法对远程服务器RESTAPI进行 CURL 调用并获取返回数据？

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

我还需要设置远程REST调用的请求标头，以及 GET（或 POST）中的查询字符串。

I find this one: http://blog.nodejitsu.com/jsdom-jquery-in-5-lines-on-nodejs

我找到了这个：http: //blog.nodejitsu.com/jsdom-jquery-in-5-lines-on-nodejs

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

但它没有显示任何方式来发布查询字符串。

Look at http.request

看着 http.request

var options = {
  host: url,
  port: 80,
  path: '/resource?id=foo&bar=baz',
  method: 'POST'
};

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);
  });
}).end();

How about using Request — Simplified HTTP client.

如何使用Request - Simplified HTTP client。

Edit February 2020: Request has been deprecated so you probably shouldn't use it any more.

2020 年 2 月编辑：请求已被弃用，因此您可能不应再使用它。

Here's a GET:

这是一个GET：

var request = require('request');
request('http://www.google.com', function (error, response, body) {
    if (!error && response.statusCode == 200) {
        console.log(body) // Print the google web page.
     }
})

OP also wanted a POST:

OP 还想要一个 POST：

request.post('http://service.com/upload', {form:{key:'value'}})

I use node-fetchbecause it uses the familiar (if you are a web developer) fetch() API. fetch() is the new way to make arbitrary HTTP requests from the browser.

我使用node-fetch是因为它使用了熟悉的（如果您是 Web 开发人员）fetch() API。fetch() 是从浏览器发出任意 HTTP 请求的新方法。

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? Fetch is a standardso how about we converge on that?

是的，我知道这是一个 node js 问题，但我们难道不想减少 API 开发人员必须记住和理解的数量，并提高我们 javascript 代码的可重用性吗？Fetch 是一个标准，那么我们如何收敛呢？

The other nice thing about fetch() is that it returns a javascript Promise, so you can write async code like this:

fetch() 的另一个好处是它返回一个 javascript Promise，因此您可以像这样编写异步代码：

let fetch = require('node-fetch');

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

Fetch supersedes XMLHTTPRequest. Here's some more info.

Fetch 取代XMLHTTPRequest。这里有更多信息。

Axios

阿克西奥斯

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

在 Node.js 中使用 Axios 的示例 (axios_example.js)：

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);

Be sure in your project directory you do:

确保在您的项目目录中执行以下操作：

npm init
npm install express
npm install axios
node axios_example.js

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

然后，您可以使用浏览器在以下位置测试 Node.js REST API： http://localhost:5000/search?queryStr=xxxxxxxxx

Similarly you can do post, such as:

同样，您可以发布帖子，例如：

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

SuperAgent

超级代理

Similarly you can use SuperAgent.

同样，您可以使用 SuperAgent。

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

And if you want to do basic authentication:

如果您想进行基本身份验证：

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

To use latest Async/Await features

使用最新的 Async/Await 功能

https://www.npmjs.com/package/request-promise-native

https://www.npmjs.com/package/request-promise-native

npm install --save request
npm install --save request-promise-native

//code

//代码

async function getData (){

one another example - you need to install request module for that

另一个例子 - 您需要为此安装请求模块

var request = require('request');
function get_trustyou(trust_you_id, callback) {

I didn't find any with cURL so I wrote a wrapper around node-libcurland can be found at https://www.npmjs.com/package/vps-rest-client.

我没有找到任何带有 cURL 的东西，所以我写了一个围绕node-libcurl的包装器，可以在https://www.npmjs.com/package/vps-rest-client找到。

To make a POST is like so:

做一个 POST 就像这样：

var host = 'https://api.budgetvm.com/v2/dns/record';
var key = 'some___key';
var domain_id = 'some___id';

var rest = require('vps-rest-client');
var client = rest.createClient(key, {
  verbose: false
});

var post = {
  domain: domain_id,
  record: 'test.example.net',
  type: 'A',
  content: '111.111.111.111'
};

client.post(host, post).then(function(resp) {
  console.info(resp);

  if (resp.success === true) {
    // some action
  }
  client.close();
}).catch((err) => console.info(err));
