Python语言,用GET方法从Restful API获取信息和用POST方法向Restful API发生数据
使用Python调Restful API
本文给出用GET方法从Restful API获取信息和用POST方法向Restful API发生消息。主要使用的包是urllib和json,其中urllib用来发送http请求,json包用来解析和构造json数据。具体例子如下:
通过GET方法获取信息
import json
from urllib import request
query_url_addr='' #the Restful api url
query_headers={'cookie':'the cooke'} #the request headers
req = request.Request(query_url_addr, headers=query_headers)
resp = request.urlopen(req)
result = resp.read().decode()
result_json = json.loads(result)#the json object of response data
用POST方法向Restful API发生消息
import json
import time
from urllib import request
from urllib import error
try:
create_url=''#the create request url
create_headers={'cookie':'the cooke'} #the request headers
body_data_str='{"body":"bodytext"}'
body_data = bytes(body_data_str, 'utf8')
req = request.Request(create_url, headers=create_headers, data=body_data, method='POST')
resp = request.urlopen(req)
result = resp.read().decode()
result_json = json.loads(result)
return result_json
except error.HTTPError as err:
error_body = err.file.read().decode()
return json.loads(result)
