Google URL Shortener官方API

Posted on by

Google终于正式推出自家的URL Shortener http://goo.gl/供用户使用了。那么接口自然会是有的，不再需要像之前一样需要自己hack才能从外部调用goo.gl压缩网址。

API地址 http://goo.gl/api/shorten
参数 security_token 和 url
未登录就将security_token值设置未null

以下是Python代码写的示例

'url':'http://google.com'}
params = urllib.urlencode(form_fields)

conn = httplib.HTTPConnection(url)
conn.request(method='POST',url = '/api/shorten',body=params,headers=headers)
response = conn.getresponse()
print response.status
 
res = response.read()
print res
 
getheaders = response.getheaders()
for head in getheaders:
print head[0],':',head[1]
conn.close()
 
if __name__ == '__main__':
test()

需要注意的是请求header信息里面必须携带Content-Type信息，否则会得到Bad request的400错误信息。
