python3 http.client 網(wǎng)絡請求

一、get 請求

'''

import http.client
#簡單的GET請求
con = http.client.HTTPConnection('www.baidu.com')
con.request("GET", "/index.html",'',{})
resu = con.getresponse()
print(resu.status,resu.reason,resu.info())  #打印讀取到的數(shù)據(jù)
#打印讀取的數(shù)據(jù)
print (resu.read())
#測試一個無效的請求
inCon = http.client.HTTPConnection('www.baidu.com')
inCon.request('GET', 'None.html')
resu2 = inCon.getresponse()
print('\n')
print(resu2.status,resu2.msg)

二、POST 請求

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()

打印結(jié)果：

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

三、head 請求

>>> 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 請求

>>> # 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)
>>> conn.request("PUT", "/file", BODY)
>>> response = conn.getresponse()
>>> print(response.status, response.reason)
200, OK
