phantomjs

I am using Selenium Webdriver in Node JS to do a Google search. When I set the browser as Firefox on my local machine, the Google results page renders as expected; it's the same as I see when I do the Google search as a human. Now, I'm trying to do the same on my Heroku server. I can't seem to get Firefox on the server, so I'm using PhantomJS. It successfully does the Google search, but some data is missing from the page (I presume it is added later by Javascript). How can I make the PhantomJS results page look the same as Firefox? Can I make PhantomJS appear to be Firefox? var driver = new

selenium介绍： selenium最初是一个自动化测试工具,而爬虫中使用它主要是为了解决requests无法直接执行JavaScript代码的问题 selenium本质是通过驱动浏览器，完全模拟浏览器的操作，比如跳转、输入、点击、下拉等，来拿到网页渲染之后的结果，可支持多种常见的浏览器 from selenium import webdriver browser=webdriver.Chrome() browser=webdriver.Firefox() browser=webdriver.PhantomJS() browser=webdriver.Safari() browser=webdriver.Edge() 官网：http://selenium-python.readthedocs.io 环境搭建 1.在python中使用selenium需要先安装对应的模块 pip install selenium 2.selenium的原理是操作驱动浏览器来完成对目标页面的请求与渲染，所以需要下载对应的浏览器驱动程序，推荐使用chrome 镜像地址：https://npm.taobao.org/mirrors/chromedriver/ 需要注意的是，驱动程序版本需要与浏览器版本对应，你可以打开chrome的关于浏览器查看到具体版本。 驱动与浏览器的版本对应关系

I'm using Phantom Node to interface node with PhantomJS. I'm trying to open pages in parallel, but the issue is that page.open callback function does not pass back the reference to the page, so I don't have a way to know which page has completed. Relevant Code self.queue[j].page.open.call( self.queue[j].page, rows[i].url, function( status ) { console.log( this ) // <-- returns undefined // So how do I keep track of which pages have finished loading? // The only variable I have available here is `status` }); Full Function Code: SnapEngine.prototype.processSnaps = function( rows, type ) { var

I have a module called util with the methods getMutedColor and some others. getMutedColor relies on another called rand in the same module. page.includeJs('https://cdnjs.cloudflare.com/ajax/libs/d3/3.4.10/d3.min.js', function() { var util = require('./util'); var svg = page.evaluate(pageContext.pageExec, data, meta, util); /** ... **/ } I can call util.getMutedColor() just fine within this scope but in my pageContext.pageExec function, util.getMutedColor no longer exists. The util parameter is still an object, but I cannot call any of the exported methods: TypeError: 'undefined' is not a
