Phantom.js / Casper.js with rotating proxy?

由 断了今生、忘了曾经 提交于 2020-01-01 09:25:10
问题 I have a simple goal: load webpages with either phantom.js (out of the box) or casper.js (nice and easier) but using proxy and rotate it from a list if current one is bad (i.e. webpage loads fail or something like that). I know casper.js has --proxy param but it dictates the user to specify only ONE proxy and use it during runtime. Question #1 is: how to rotate proxy on the fly programmatically? I did some research and found this node-requester but it's not integrated with casper.js . I tried

How to for loop in casperjs

问题 I am trying to click a 'next' button N number of times and grab the page source each time. I understand that I can run an arbitrary function on the remote website, so instead of click() I just use the remote function nextPage() How do I run the following, an arbitrary number of times: var casper = require('casper').create(); casper.start('http://www.example.com', function() { this.echo(this.getHTML()); this.echo('-------------------------'); var numTimes = 4, count = 2; casper.repeat(numTimes

CasperJS can not trigger twitter infinite scroll

由 天大地大妈咪最大 提交于 2020-01-01 05:12:11
问题 I am trying to get some information from twitter using CasperJS . And I'm stuck with infinite scroll. The thing is that even using jquery to scroll the page down nothings seems to work. Neither scrolling, neither triggering the exact event on window (smth like uiNearTheBottom) doesn't seem to help. Interesting thing - all of these attempts work when injecting JS code via js console in FF & Chrome. Here's the example code : casper.thenEvaluate(function(){ $(window).trigger('uiNearTheBottom');

问题 I am using casperjs for some webscraping and am having a strange problem. I want to be able to construct a CSS path from strings and get an array using 'querySelectorAll' like below: var tier = '-ou-'; var index = 'div.list > div > a[href*="' + tier + '"]'; var battles = document.querySelectorAll(index); However, this does not work, and battles returns null. This version works: var links = document.querySelectorAll('div.list > div > a[href*="-ou-"]'); But none other does. I also tried: var

问题 Going through the casperjs documentation I couldn't find where I could see the console.log from client-side javascript. Is this possible? 回答1: I'm not really sure to fully understand your question, but you can do something like the following: var casper = require('casper').create({ logLevel: "debug" }); casper.on('remote.message', function(message) { this.echo(message); }); casper.start('http://google.com/', function() { this.evaluate(function sendLog(log) { // you can access the log from

问题 I've downloaded the latest version of casperjs (1.03) and phantomjs (1.9.2). So I took this little simple script from the casper page: var casper = require('casper').create({ verbose: true, logLevel: "debug" }); var casper = new require('casper').Casper(); and when I try to run it I get the following error: noname:phantomjs-1.9.2 Tom$ casperjs/bin/casperjs tipico2.js Fatal: [Errno 2] No such file or directory; did you install phantomjs? So, this is my directory structure: phantomjs-1.9.2/ <--

How to tell CasperJS to loop through a series of pages

由 不问归期 提交于 2019-12-30 00:36:08
问题 I try to make CasperJS achieve the following: Go through a series of pages that are named sequentially by date. On each page, locate a PDF link. Download the PDF. I got some working code, but I don't understand how CasperJS is going through the sequence of events. For instance, in the code sample below, CasperJS tries to process step 2, and throws a "ReferenceError: Can't find variable: formDate", while step 1 isn't executed at all for some reason. What's wrong with my reasoning? It seems to
