I'm trying to execute phantomjs using node-lambda and bits and pieces I found on the web mainly https://github.com/justengland/phantom-lambda-template I had some problems deploying node-lambda with node43 but manually installing the latest source seems to have helped in that regard. but now I'm having trouble running the lambda functions.

CasperJS File Download Times Out After 30 Seconds

问题 I'm using CasperJS to download a 15 MB file. In the browser, the download takes about 3 minutes to complete. With Casper, the .download function for the same url returns after exactly 30 seconds, and the file written to disk is 0 bytes. I've tried setting longer timeouts like this: var casper = require("casper").create({ pageSettings: { webSecurityEnabled: false }, waitTimeout: 500000, stepTimeout: 500000 }); But they have no effect. Here's my download function: casper.on('resource.received',

问题 I am currently writing a web-application that involves some web-scraping. To help with this, I am employing the help of phantomjs. However, certain (but not all) web pages are returning a status="fail". Here is the code (note: This is actually written in nodejs using the node-phantom library found here: https://github.com/alexscheelmeyer/node-phantom. While the syntax may be different, the library actually works directly with phantomjs so it shouldn't be doing anything different: phantom

Paginating HTML document for printing with WebKit-based browsers

问题 Internet Explorer has Print Template engine , where I can use DEVICERECT element to represent a physical page, then use LAYOUTRECT element as a rectangular view to flow the HTML document through into the page and drive the pagination. That prevents lines from being cut-off in the middle between adjacent pages. This mechanism is described in details here. Does WebKit provide a similar feature? Specifically, does PhantomJS do? I'm looking for anything that would allow to paginate an existing

grunt-contrib-jasmine and PhantomJS security

由 孤街浪徒 提交于 2019-11-30 14:16:01
问题 I'm getting an error XMLHttpRequest cannot load https://my-api.domain.com. Origin file:// is not allowed by Access-Control-Allow-Origin. when I try to run some async unit tests that query an API through grunt-contrib-jasmine, which in turn using PhantomJS. I see that the command line version of PhantomJS does have a 'web-security' options. Can I control how grunt-contrib-jasmine uses PhantomJS to include this option and disable the cross-domain security? 回答1: You can pass options to phantomjs
