对Python实现简单的API接口实例讲解

# coding:utf-8
 
import json
from urlparse import parse_qs
from wsgiref.simple_server import make_server
 
 
# 定义函数，参数是函数的两个参数，都是python本身定义的，默认就行了。
def application(environ, start_response):
 # 定义文件请求的类型和当前请求成功的code
 start_response(\'200 OK\', [(\'Content-Type\', \'text/html\')])
 # environ是当前请求的所有数据，包括Header和URL，body，这里只涉及到get
 # 获取当前get请求的所有数据，返回是string类型
 params = parse_qs(environ[\'QUERY_STRING\'])
 # 获取get中key为name的值
 name = params.get(\'name\', [\'\'])[0]
 no = params.get(\'no\', [\'\'])[0]
 
 # 组成一个数组，数组中只有一个字典
 dic = {\'name\': name, \'no\': no}
 
 return [json.dumps(dic)]
 
 
if __name__ == \"__main__\":
 port = 5088
 httpd = make_server(\"0.0.0.0\", port, application)
 print \"serving http on port {0}...\".format(str(port))
 httpd.serve_forever()
