使用node.js发送Content-Type:application/json post

Question

我们如何在NodeJS中发出这样的HTTP请求？示例或模块表示赞赏.

curl https://www.googleapis.com/urlshortener/v1/url \
  -H 'Content-Type: application/json' \
  -d '{"longUrl": "http://www.google.com/"}'

Answer 1

Mikeal的请求模块可以轻松完成:

var request = require('request');

var options = {
  uri: 'https://www.googleapis.com/urlshortener/v1/url',
  method: 'POST',
  json: {
    "longUrl": "http://www.google.com/"
  }
};

request(options, function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body.id) // Print the shortened url.
  }
});

Answer 2

简单的例子

var request = require('request');

//Custom Header pass
var headersOpt = {  
    "content-type": "application/json",
};
request(
        {
        method:'post',
        url:'https://www.googleapis.com/urlshortener/v1/url', 
        form: {name:'hello',age:25}, 
        headers: headersOpt,
        json: true,
    }, function (error, response, body) {  
        //Print the Response
        console.log(body);  
}); 

Answer 3

正如官方文件所说:

body - PATCH,POST和PUT请求的实体主体.必须是Buffer,String或ReadStream.如果json为true,则body必须是JSON可序列化对象.

发送JSON时,您只需将其放在选项的正文中即可.

var options = {
    uri: 'https://myurl.com',
    method: 'POST',
    json: true,
    body: {'my_date' : 'json'}
}
request(options, myCallback)

Answer 4

Axios更少但更好：

const data = JSON.stringify({
  message: 'Hello World!'
})

const url = "https://localhost/WeatherAPI";

axios({
    method: 'POST',
    url, 
    data: JSON.stringify(data), 
    headers:{'Content-Type': 'application/json; charset=utf-8'}
}) 
  .then((res) => {
    console.log(`statusCode: ${res.status}`)
    console.log(res)
  })
  .catch((error) => {
    console.error(error)
  })
