[英]Why does my console display a stack trace from a Thrift exception raised within a try block?
我的節儉客戶端當前未連接,因此對self.transport.open()
的調用應超時,並且我的程序應繼續執行。 但是我想知道為什么超時會引發異常,為什么堆棧跟蹤會打印到控制台,以及這是否表明存在問題。
編碼:
def connect(self, url=None):
"""Attempt to connect to supervisor Thrift server"""
if conf.TESTING:
return
try:
self.url = url if url is not None else self.url
self.socket = TSocket.TSocket(self.url, constants.kSupervisorPort)
self.socket.setTimeout(1000)
self.transport = TTransport.TBufferedTransport(self.socket)
self.protocol = TBinaryProtocol.TBinaryProtocol(self.transport)
self.client = Supervisor.Client(self.protocol)
log.warning("...Im about to raise an exception from inside a try block!")
self.transport.open()
self.connected = True
log.info('[TaskStateClient] Connected at url: ' + self.url)
except Exception:
log.warning("...and now Im handling the raised exception...")
和堆棧跟蹤:
-> Running
python app.py
werkzeug : INFO * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
root : WARNING ...Im about to raise an exception from inside a try block!
thrift.transport.TSocket: INFO Could not connect to ('192.168.1.219', 9002)
Traceback (most recent call last):

您使用以下命令打印活動記錄器
import logging
for key in logging.Logger.manager.loggerDict:
print(key)
然后,對於與TSocket相關的記錄器,可以將調試級別設置為critical
logging.getLogger('thrift.transport.TSocket').setLevel(logging.CRITICAL)
要么
logging.getLogger('thrift.transport.TSocket').setLevel(logging.NOTSET)
