问题描述

我正在尝试编写登录到网站的特定脚本.这个特定的网站包含一个Javascript形式，因此使用机械化"对我几乎没有运气.

I'm attempting to write a particular script that logs into a website. This specific website contains a Javascript form so I had little to no luck by making use of "mechanize".

谢谢.

推荐答案

我最近一直在使用 PhantomJS 用于此类工作-这是一个命令行工具，可让您在浏览器环境(基于Webkit)中运行Javascript.这使您可以进行需要启用Javascript的界面的抓取和在线交互.这里有一个基于Python的实现，它与C ++版本的API完全兼容，或者您​​可以通过subprocess在Python中运行任一版本.

I've recently been using PhantomJS for this kind of work - it's a command-line tool that allows you to run Javascript in a browser environment (based on Webkit). This allows you to do scraping and online interactions that require Javascript-enabled interfaces. There's a Python-based implementation here that's fully compatible with the API of the C++ version, or you could run either version in Python via subprocess.

根据您要执行的操作，另一个不错的选择可能是使用具有客户端驱动程序的 Selenium 在Python中实现-这是用于集成测试的，但是只要您可以运行基于Java的Selenium Server，并使自动化发生在开放的浏览器中，而不是作为后台进程，就可以执行很多自动化操作.

Depending on what you're trying to do, another good option might be to use Selenium, which has client driver implementation in Python - it's meant for integration testing, but can do a lot of automation as long as you're okay running the Java-based Selenium Server and having the automation happen in an open browser rather than as a background process.
