python之接口请求

#coding=utf-8
import httplib,urllib
import json

httpClient=None
try:
   httpClient=httplib.HTTPConnection('test.web.com',80,timeout=30)#注意，此处域名不要带http://
   headers={'Accept':'application/json','cookie':'PHPSESSID=xxxxx'}#如果有headers的话就带上。没有则不用
   httpClient.request(method='GET',url='/main/?r=get/student',headers=headers)
   response=httpClient.getresponse()
   data=json.load(response,encoding='utf-8')#将获取到的内容转换为json类型数据
except Exception,e:
    raise e
finally:
   if httpClient:
   	   httpClient.close()

2、httplib模块之post请求，直接上代码


#coding=utf-8
import httplib,urllib
import json

httpClient=None
try:
   httpClient=httplib.HTTPConnection('test.web.com',80,timeout=30)#注意，此处域名不要带http://
   headers={'Content-type':'application/x-www-form-urlcoded','Accept':'text/plain','cookie':'PHPSESSID=xxxxx'}#post请求头需要有content-type，否则失败
   #尝试过，不知道为啥。。
   params=urllib.urlencode({"ID:292})#post的参数，这里需要是一个对象的形式
   httpClient.request('POST','/main/?r=get/student',params,headers)#这里可以不带key，直接用value
   response=httpClient.getresponse()
   data=json.load(response,encoding='utf-8')#将获取到的内容转换为json类型数据
   print "name=%s"%(data['name'])#直接读取
except Exception,e:
   raise e
finally:
   if httpClient:
      httpClient.close()

3、python另有一种请求接口的方法，就是用urllib的urlopen方法直接请求，用法如下


response=urllib.urlopen('http://test.web.com/main/?r=get/student&ID=%s'%(stu_id))#id自己定义
