python使用httpHandler处理请求案例

#coding=utf-8
#HTTPHandler & opener 
#更高级一些功能，可以高仿模拟浏览器
import urllib.request
import urllib.parse
url = "https://www.baidu.com/";
handler = urllib.request.HTTPHandler();
opener  = urllib.request.build_opener(handler);
headers={
    ‘User-Agent‘: ‘Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36‘
};
request = urllib.request.Request(url =url,headers=headers);
response = opener.open(request);
print(response.read());
