刮谷歌新聞

Question

I M試圖湊谷歌新聞，但出了故障代碼I M使用：

var express = require('express'); 
var request = require('request'); 
var cheerio = require('cheerio'); 
var path = require('path'); 
var fs =require('fs'); 
var app = express(); 
var port = 8080; 


// Define the requests url 

var url = "https://news.google.com/news"; 

request(url,function(err,res,body){ 

var news=[]; 
var $page = cheerio.load(body); 

var $url=$page('table[class="esc-layout-table"]').find('tbody > tr > td > div > h2 > a').each(function (index, element) { 
    news.push($page(element).attr('href')); 
}); 
news={ 
//desc:$desc, 
    url:$url, 
// img:$img, 
}; 



console.log ('success ....'news); 



}); 

我想有鏈接的文章和標題，以及縮略圖。我將存儲在一個火力點數據庫 但不幸的是我得到了休息失去了我的控制檯登錄 我不能得到的結果，我期望相反，我得到這個在控制檯：

success .... { '0':

注：這只是少數結果如果你運行代碼，你會清楚地看到我的意思 感謝您的建議傢伙。

Answer 1

不知道這是你想要的，但試試這個我得到了所有的URL像你想

var express = require('express'); 
var request = require('request'); 
var cheerio = require('cheerio'); 
var path = require('path'); 
var fs =require('fs'); 
var app = express(); 
var port = 8080; 


// Define the requests url 

var url = "https://news.google.com/news"; 

request(url,function(err,res,body){ 

var news=[]; 

var $= cheerio.load(body); 

$('table[class="esc-layout-table"]').each(function() { 
    var image = $(this).find('tbody > tr > .esc-layout-thumbnail-cell > .esc-thumbnail-wrapper > .esc-thumbnail-state > .esc-thumbnail > a > .esc-thumbnail-image-wrapper > img').attr('src'); 
    var title = $(this).find('tbody > tr > .esc-layout-article-cell > .esc-lead-article-title-wrapper > .esc-lead-article-title > a > span').text(); 
    var url = $(this).find('tbody > tr > .esc-layout-article-cell > .esc-lead-article-title-wrapper > .esc-lead-article-title > a').attr('href'); 
    news.push({ url, title, image }); 
}); 


console.log ('success ....', news); 



}); 

結果

success .... [ { url: 'http://www.cbc.ca/news/canada/saskatchewan/prisoner-killed-sask-penitentiary-1.3898175', 
    title: '1 dead, at least 8 injured in Saskatchewan prison riot',
