Question

您好我尝试请求一些json，一切正常，但有时请求出错，可能是网站堆栈或关闭连接对我来说，因为我每隔15分钟请求json。

代码在这里：

def request_coins(config):
    coins = None
    print(str(datetime.now()) + ' - REQUESTING Coins')
    while coins is None:
        try:
            coins = (requests.get(url=str(config['UrlPath']['url']) + str(config['UrlPath']['userrates'])))
        except:
            print(str(datetime.now()) + " - Site didn't respond. Reconnecting in 10 sec")
        time.sleep(10)
     if coins is not None:
        coins = coins.json()['coins']
        print(str(datetime.now()) + ' - Coins received correctly')
return coins

问题是try-catch在我的情况下不起作用。在print(str(datetime.now()) + ' - REQUESTING Coins')中请求堆栈，我没有收到任何异常和消息给cmd

print(str(datetime.now()) + " - Site didn't respond. Reconnecting in 10 sec")

我理解try: coins = (requests.get(url=str(config['UrlPath']['url']) + str(config['UrlPath']['userrates'])))

处的代码堆栈

并且不要去except：

知道如何解决？

只需添加timeout即可获得请求

Python请求堆栈
