python学习之 urllib的post与get

 当urlopen中data为None或不写时，此时为GET；

当data不为None时，此时为POST

from urllib import request,parse
import json

url = 'http://192.168.10.1/api.php'
req = request.Request(url)
data = parse.urlencode({'c':'get_equipment_list',
                        'token':'9b90b4accacfe148d820f242ce19b294'})
res = request.urlopen(req, data=data.encode('utf-8'))
data = res.read()
out = json.loads(data)

urlopen中传递data值时，此时为post，通过wireshark捕获如下：

from urllib import request,parse
import json

url = 'http://192.168.10.1/api.php'
req = request.Request(url)

res = request.urlopen(req, data=None)
data = res.read()
out = json.loads(data)
