【Pyton】访问Java提供的Rest接口示例

代码：

# coding=utf-8
import urllib.request

url="http://localhost:8080/mediacool/probeUser"

param_dict={'name':'何杨','pswd':'1'}
param_str=urllib.parse.urlencode(param_dict)
params_bytes=param_str.encode()

req=urllib.request.Request(url,data=params_bytes)
with urllib.request.urlopen(req) as rsps:
    data=rsps.read()
    json_data=data.decode();
    print(json_data)

输出：

C:\hy\py>python postMediaCoolUser.py
{"Interface ID":"8973","startTime":"2021-10-31 12:08:33.793817800","visitorIp":"0:0:0:0:0:0:0:1","code":"303","msg":"确 认用户名和密码无误","userInfo":{"id":1,"name":"何杨","email":"1@2.3"},"endTime":"2021-10-31 12:08:33.799822200"}
