var request = require('request');
var fs = require('fs');
var cheerio = require("cheerio");
var url = 'http://www.fssxhsd.com/category.php?id=332';
request(url,function(err,result){
if(err){
console.log(err);
}
var $ = cheerio.load(result.body);
$('dl img').each(function(index,element){
var img_src = 'www.fssxhsd.com/' + $(this).attr('src');
console.log(img_src)
//采用request模块,向服务器发起一次请求,获取图片资源
request.head(img_src,function(err,res,body){
if(err){
console.log(err);
}
});
request(img_src).pipe(fs.createWriteStream('./image/'+index));
})
})
这是我的代码,但是报错:
