python2 实时获取最新的汇率表

获取汇率

def get_rate(self, time):

    # Where USD is the base currency you want to use
    # 我的需求是获取美元对印尼币的汇率,我存在了自己建立的一张表中,此方法效果是判断我调用的时候传入的时间,如果和表中的
    一致,就直接用数据库表中的,如果不一致就调用api获取最新的汇率,保证一天只请求一次api,因为这个免费的api是需要收费
    的,一个月只能请求1000次,
    url = 'https://v3.exchangerate-api.com/bulk/fa192ccf2d553fe2b4005125/USD'
    # Making our request
    try:
        sql = "SELECT rate, savetime from JD_rate"
        self.cur_test.execute(sql)
        result_a = self.cur_test.fetchone()[0]
        rate = result_a[0]

        savetime = result_a[1].encode("utf-8")[:11]
        if savetime != time:
            response = requests.get(url)
            rate = response.json()['rates']['IDR']
            sql1 = "UPDATE JD_rate set rate='%s', savetime='%s' WHERE id = 1" % (rate, time)
            self.cur_test.execute(sql1)
            self.coon_test.commit()
        return rate
    except Exception, ex:
        traceback.print_exc()
        print ex, "get_rate"
