用法很的简单,下面是一个程序片段。
@conn_try_again def post_query_bandwidth_for_bandwidth(self, contract_no, data_month, product_code): #根据webluker接口情况获取计费数据 try: post_data = {'contract':contract_no, 'month': data_month, 'code':product_code} params = urllib.urlencode(post_data) response = urllib2.urlopen(WEBLUKER_BANDWITH_API + "?" +params) billdata = {} billdata = response.read() if not billdata: billdata = {} return billdata except Exception, err: err = u'与webluker接口间通信异常' raise Exception(err)
如果try块中有异常,就会自动重试2次。
