get请求：

import requests
#r=requests.get("http://www.cnblogs.com/yoyoketang")
par={"keywords":"yoyoketang"}
s=requests.get("http://zzk.cnblogs.com/s/blogpost",params=par,verify=False)
b=requests.get("https://www.baidu.com/",verify=False)
print(b.url)         #获取URL
print(b.status_code)      #响应状态码
print(b.encoding)   #编码格式
print(b.content)     #字节方式的响应体，会自动解码
print(b.headers)   #以map方式存响应头
print(b.cookies)   #获取cookies
print(b.json)     #json解码器
print(b.raw)    #返回原始响应体
###
#print(r.status_code)
print(s.status_code)
#print(r.text)
print(s.text)      #字符串方式的响应体
print(s.raise_for_status())   #请示失败抛出异常
