使用Javascript获取最终HTML将Java呈现为字符串 [英] Getting Final HTML with Javascript rendered Java as String

问题描述

我想从HTML页面获取数据（刮掉它）。但它包含javascript的评论。在普通的java url fetch中，我只获取了没有执行Javascript的HTML（实际的）。我想要执行Javascript的最终页面。

I want to fetch data from an HTML page(scrape it). But it contains reviews in javascript. In normal java url fetch I am only getting the HTML(actual one) without Javascript executed. I want the final page with Javascript executed.

示例： - http://www.glamsham.com/movies/reviews/rowdy-rathore-movie-review-cheers-for-rowdy- akki-051207.asp

此页面的评论为facebook插件，以Javascript格式提取。

This page has comments as a facebook plugin which are fetched as Javascript.

即便如此。
http://www.imdb.com/title/tt0848228/reviews

我该怎么办？

推荐答案

使用 phantomjs ： http://phantomjs.org

var page = require('webpage').create();
page.open("http://www.glamsham.com/movies/reviews/rowdy-rathore-movie-review-cheers-for-rowdy-akki-051207.asp")
setTimeout(function(){
    // Where you want to save it    
    page.render("screenshoot.png")  
    // You can access its content using jQuery
    var fbcomments = page.evaluate(function(){
        return $(".fb-comments iframe").contents().find(".postContainer") 
    }) 
},10000)

你必须在幻影中使用该选项 - web-security = no 允许跨域交互（即对于facebook iframe）

You have to use the option in phantom --web-security=no to allow cross-domain interaction (ie for facebook iframe)

要与phantomjs中的其他应用程序通信，您可以使用Web服务器或进行POST要求： https://github.com/ariya/phantomjs/blob/master /examples/post.js

To communicate with other applications from phantomjs you can use a web server or make a POST request: https://github.com/ariya/phantomjs/blob/master/examples/post.js
