用python发送GET和POST请求

from urllib import parse,request
textmod={'user':'admin','password':'admin'}
textmod = parse.urlencode(textmod)
print(textmod)
#输出内容:user=admin&password=admin
header_dict = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko'}
url='http://192.168.199.1:8000/mainsugar/loginGET/'
req = request.Request(url='%s%s%s' % (url,'?',textmod),headers=header_dict)
res = request.urlopen(req)
res = res.read()
print(res)
#输出内容(python3默认获取到的是16进制'bytes'类型数据 Unicode编码，如果如需可读输出则需decode解码成对应编码):b'\xe7\x99\xbb\xe5\xbd\x95\xe6\x88\x90\xe5\x8a\x9f'
print(res.decode(encoding='utf-8'))
#输出内容:登录成功

from urllib import parse,request

import json

textmod={"jsonrpc": "2.0","method":"user.login","params":{"user":"admin","password":"zabbix"},"auth": None,"id":1}

#json串数据使用

textmod = json.dumps(textmod).encode(encoding='utf-8')

#普通数据使用

textmod = parse.urlencode(textmod).encode(encoding='utf-8')

print(textmod)

#输出内容:b'{"params": {"user": "admin", "password": "zabbix"}, "auth": null, "method": "user.login", "jsonrpc": "2.0", "id": 1}'

header_dict = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko',"Content-Type": "application/json"}

url='http://192.168.199.10/api_jsonrpc.php'

req = request.Request(url=url,data=textmod,headers=header_dict)

res = request.urlopen(req)

res = res.read()

print(res)

#输出内容:b'{"jsonrpc":"2.0","result":"37d991fd583e91a0cfae6142d8d59d7e","id":1}'

print(res.decode(encoding='utf-8'))

#输出内容:{"jsonrpc":"2.0","result":"37d991fd583e91a0cfae6142d8d59d7e","id":1}

cookie的使用（python3.5）：

from urllib import request,parse

from http import cookiejar

#创建cookie处理器

cj = http.cookiejar.CookieJar()

opener = request.build_opener(request.HTTPCookieProcessor(cj), request.HTTPHandler)

request.install_opener(opener)

#下面进行正常请求
