Problem in saving the image saving from url in nodejs

问题

I'm trying to scrap data from website while scrapping it i'm getting error like file "An error ocured while loading image" while opening image from my server directory.image is stored with extension but the image is not opening properly

var request = require('request');  
var cheerio = require('cheerio');

const fs = require("fs");


function hello (){
    url = '';
    request(url, function(error, response, html){


        if(!error){
            var $ = cheerio.load(html);
             var img = $('img.control-label');
             var img_url = $('img.control-label').attr('src')
             console.log(img);
             console.log(url+img_url);

            request({url: url+img_url, headers: {Cookie: response.headers,encoding:null  }}, function(error1, response1, body){
                if(!error){ 
                    path1 = './image/new.jpeg';
                    data = "data:" + response.headers["content-type"] + ";base64," + new Buffer(body).toString('base64');
                    console.log(data); 
                    fs.writeFile(path1, body, {encoding: 'base64'}, function(err){
                      });

                }
            })
        }
    })
}
hello();

回答1:

This is a deprecation warning (I don't think it's an error yet, but it will be soon).

You just need to change the way you call Buffer. Instead of instantiating it directly use the static from method.

new Buffer(body)  // Old
Buffer.from(body) // New

回答2:

Replace

fs.writeFile(path1, body, {encoding: 'base64'}, function(err){
                  });

With

fs.writeFile(path1, 'data:image/jpeg;base64,' + new Buffer(body).toString('base64'), {encoding: 'base64'}, function(err){
                  });
