import http.client

#简单的GET请求
con = http.client.HTTPConnection('www.baidu.com')
con.request("GET", "/index.html",'',{})
resu = con.getresponse()
print(resu.status,resu.reason,resu.info())  #打印读取到的数据

#打印读取的数据
print (resu.read())

#测试一个无效的请求
inCon = http.client.HTTPConnection('www.baidu.com')
inCon.request('GET', 'None.html')
resu2 = inCon.getresponse()
print('\n')
print(resu2.status,resu2.msg)

二：POST 请求

   

import http.client,urllib.parse

pararms = urllib.parse.urlencode({'@number': 12524, '@type': 'issue', '@action': 'show'})
headers = {"Content-type": "application/x-www-form-urlencoded","Accept": "text/plain"}
conn = http.client.HTTPConnection("bugs.python.org")
conn.request('POST', '', pararms, headers)
response = conn.getresponse()
print(response.status, response.reason)
data = response.read()
print(data)

conn.close()

   打印结果 ：

  

302 Found
b'Redirecting to <a href="http://bugs.python.org/issue12524">http://bugs.python.org/issue12524</a>'

三： head 请求

>>> import http.client
>>> conn = http.client.HTTPConnection("www.python.org")
>>> conn.request("HEAD","/index.html")
>>> res = conn.getresponse()
>>> print(res.status, res.reason)
200 OK
>>> data = res.read()
>>> print(len(data))
0
>>> data == b''
True

四：put 请求

 

>>> # This creates an HTTP message
>>> # with the content of BODY as the enclosed representation
>>> # for the resource http://localhost:8080/file
...
>>> import http.client
>>> BODY = "***filecontents***"
>>> conn = http.client.HTTPConnection("localhost", 8080)
