Question

我正在从教程中为node.js编写基本代码，它应该从url位置：https://jsonplaceholder.typicode.com/posts上的文件中获取json数据。并将其保存在使用相同代码创建的新文件中。我的代码在下面

const https=require('https');
const fs=require('fs');
const url='https://jsonplaceholder.typicode.com/posts';
https.get('url', res => {

    res.setEncoding('utf8');

    let body='';

    res.on('data', data => {
       body += data;

    });
   res.on('end', ()=>{
  fs.writeFile('data.json', body, 'utf8', (err)=>{
      if(err) return err;
      consle.log('data was saved');
  });
   });
});

It give me this error

https.js：235 引发新错误.Error（'ERR_INVALID_DOMAIN_NAME'）; ^

Error [ERR_INVALID_DOMAIN_NAME]: Unable to determine the domain name

谁能告诉我我错了

Answer 1

https.get(url, res => {

代替

https.get('url', res => {

无法使用Node JS从URL接收Jason数据
