Python 爬虫常见的坑和解决方法

1.请求时出现HTTP Error 403: Forbidden

headers = {‘User-Agent‘:‘Mozilla/5.0 (Windows NT 6.1; WOW64; rv:23.0) Gecko/20100101 Firefox/23.0‘}  

req = urllib.request.Request(url=url, headers=headers)  

urllib.request.urlopen(req).read()

2.保存html内容时出现Python UnicodeEncodeError: ‘gbk‘ codec can‘t encode character

将

f = open("out.html","w")

换成

f = open("out.html","w",encoding=‘utf-8‘)
