我遇到此错误:
线程StompReceiverThread-1中的异常(最有可能在 解释器关闭):
那根本不是追溯。 通常,一切正常,但很少发生,然后动作无法结束。
有什么提示吗? 我的代码:
class Listener(stomp.ConnectionListener):
def __init__(self, conn, request):
self.conn = conn
self.request = request
def on_error(self, headers, message):
global WAITING_RESPONSE
print('received an error: ' + message)
WAITING_RESPONSE = False
def on_message(self, headers, message):
global WAITING_RESPONSE
try:
msg = json.loads(message)
if str(msg.get('transaction_id','')) == str(CURRENT_ID):
printDebugLine('Queue response:'+str(message))
manageQueueResponse(message,self.request)
WAITING_RESPONSE = False
self.conn.ack(headers['message-id'], '11')
except stomp.exception.ConnectFailedException:
print('Stomp error on message')
sys.exit(3)
except Exception as e:
print('ERROR: %s' % str(e))
sys.exit(3)
class Queue(object):
def __init__(self):
self.host = xx
self.port = xx
self.login = xx
self.passwd = xx
self.request = {}
self.start()
def start(self):
try:
self.conn = stomp.Connection(host_and_ports=[(self.host, self.port)])
self.conn.start()
self.conn.connect(self.login, self.passwd, wait=True)
self.conn.set_listener('xx', Listener(self.conn, self.request))
self.conn.subscribe(destination='xx', id='xx', ack='xx')
except stomp.exception.ConnectFailedException:
print('ERROR: unable to connect')
sys.exit(3)
except Exception as e:
print('ERROR: %s' % str(e))
sys.exit(3)
def send(self, data):
global CURRENT_ID
while WAITING_RESPONSE:
time.time(0.1)
try:
CURRENT_ID = str(uuid.uuid4())
data.update({'transaction_id': CURRENT_ID})
b = json.dumps(data)
self.request.update(data)
printDebugLine('Queue request:'+str(data))
self.conn.send(body=b, destination='xx')
timeout(data,self.request,29)
except stomp.exception.ConnectFailedException:
print('ERROR: unable to connect')
except Exception as e:
print('ERROR: %s' % str(e))
答案 0 :(得分:0)
看起来您的主程序正在退出,解释器正在清理内容,但是stomp接收器线程并未首先关闭。接收器线程可以做一些事情,但是基本模块不再可用,因此它会发出异常消息,但是由于由于程序退出而无法再使用该功能,因此无法打印回溯。
看看为什么要退出主程序。
