Question

python3 urllib加头信息

import urllib.request
header = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.104 Safari/537.36 Core/1.53.4549.400 QQBrowser/9.7.12900.400'}

res = urllib.request.urlopen(url,headers = header)
以前这样加是成功的，现在python3 好像加不成功了。应该怎么弄

Answer 1

def get(url, headers=None, timeout=2, decode='utf-8'):
    rt = HttpReturn()
    try:
        if headers is None:
            hr = urllib.request.urlopen(url, timeout=timeout)
        else:
            req = urllib.request.Request(url, None, headers)
            hr = urllib.request.urlopen(req, timeout=timeout)
        rt.obj = hr
        rt.text = hr.read().decode(decode)
        rt.status = hr.status
    finally:
        return rt

这是我写的一个函数，你看看应当是这种用法
