python获取网页源代码

最简单的网页取源（不用模拟浏览器的情况）

 1 import requests
 2 def getHTML(url):
 3     try:
 4         r = requests.get(url,timeout=30)
 5         r.raise_for_status()
 6         r.encoding = 'utf-8'
 7         return r.text
 8     except:
 9         return ""
10 url = "http://baidu.com"
11 print(getHTML(url))
