过去几个月来，我一直在成功查询api，没有出现任何问题。今天，我得到一个错误，尽管代码没有更改。我过去曾在这里问过类似的问题。 ConnectionResetError: [Errno 104] Connection reset by peer python 3推荐的解决方案可以解决问题，直到今晚。我已将代码与错误消息一起分解到最低限度。关于如何解决它的任何建议和/或关于为什么查询并不总是可靠的任何见解将不胜感激。谢谢！
def getOaCandles():
#build the main request
headers = getHeader() #contains user name and token
url = 'https://apifxtrade.oanda.com/v3/instruments/EUR_USD/candles/'
response = requests.get( url=url, headers=headers )
if response.status_code == 200:
candles = response.json().get( 'candles' )
print( candles )
else:
print( '\nOanda response status:{}\n'.format(response.status_code ))
return None
getOaCandles()
通常我会收到json对象的列表。但这是错误：
