我发现超级药剂真的很有用， 非常简单 例如

const superagent=require('superagent')
superagent
.get('google.com')
.set('Authorization','Authorization object')
.set('Accept','application/json')

我使用节点获取，因为它使用熟悉的(如果你是一个web开发人员)fetch() API。fetch()是从浏览器发出任意HTTP请求的新方法。

是的，我知道这是一个节点js的问题，但我们不希望减少API的开发者必须记住和理解的数量，并提高我们的javascript代码的可重用性吗?Fetch是一个标准，所以我们收敛一下如何?

fetch()的另一个好处是它返回一个javascript Promise，所以你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);});

Axios

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);

确保在你的项目目录中:

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

然后，您可以在http://localhost:5000/search?queryStr=xxxxxxxxx上使用浏览器测试Node.js REST API

类似地，你可以做post，比如:

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

SuperAgent

类似地，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));
});

如果你想做基本的身份验证

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));
});

我发现超级药剂真的很有用， 非常简单 例如

const superagent=require('superagent')
superagent
.get('google.com')
.set('Authorization','Authorization object')
.set('Accept','application/json')

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);
}
