I heard that Python is very convenient to do web crawler, just this few days units also have such needs, the need to visit XX website to download some documents, so that their own personal test, the effect is good. In this example, a website that is logged in needs to provide a username, password, and verification code that uses Python's urllib2 to log in direct

The simple introduction to urllib2 is mentioned earlier. The following describes how to use urllib2. 1. Proxy Settings By default, urllib2 uses the environment variable http_proxy to set HTTP proxy. If you want to explicitly control the proxy in the program without being affected by environment variables, you can use the proxy. Create test14 to implement a simple proxy Demo: import urllib2enable_proxy = Trueproxy_handler = urllib2.ProxyHandler({"http" : 'http://some-proxy.com:8080'})null_proxy

When you use Python to collect data from some websites, you often encounter situations where you need to log in. In these cases, when using a browser such as Firefox to log in, the debugger (shortcut key F12) can see the log in when the Web page to the server to submit information, this part of the information can be extracted from the Python urllib2 library with a cookie to simulate login and then collect

Cookies, which are data stored on the user's local terminal (usually encrypted) by certain websites in order to identify users and perform session tracking.For example, some sites need to log in to access a page, before you log in, you want to crawl a page content is not allowed. Then we can use the URLLIB2 library to save our registered cookies, and then crawl the other pages to achieve the goal.[Email protected]~]# cat cscook.py#!/usr/bin/python#-*-
