使用最新的Async/Await特性

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

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

/ /代码

async function getData (){
    try{
          var rp = require ('request-promise-native');
          var options = {
          uri:'https://reqres.in/api/users/2',
          json:true
        };

        var response = await rp(options);
        return response;
    }catch(error){
        throw error;
    }        
}

try{
    console.log(getData());
}catch(error){
    console.log(error);
}

您可以使用curlrequest轻松设置请求的时间…你甚至可以在选项中设置头信息来“伪造”浏览器调用。

警告:截至2020年2月11日，请求已完全弃用。

如果你使用form-data实现，更多信息请访问https://tanaikech.github.io/2017/07/27/multipart-post-request-using-node.js):

var fs = require('fs');
var request = require('request');
request.post({
  url: 'https://slack.com/api/files.upload',
  formData: {
    file: fs.createReadStream('sample.zip'),
    token: '### access token ###',
    filetype: 'zip',
    filename: 'samplefilename',
    channels: 'sample',
    title: 'sampletitle',
  },
}, function (error, response, body) {
  console.log(body);
});

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

POST是这样的:

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));

2022年更新:

从node.js v18版本开始，你可以使用全局可用的获取API(参见https://nodejs.org/en/blog/announcements/v18-release-announce/)

在他们的公告页面上还有一个用法示例:

const res = await fetch('https://nodejs.org/api/documentation.json');
if (res.ok) {
  const data = await res.json();
  console.log(data);
}
