我调用一个函数，它从kafka producer发送一些数据，但是在它发送之后，我返回一个不返回的响应。代码在返回时被卡住。有人知道发生了什么吗？
我的代码如下：，

def postEvent(eventData):
    print("The eventData is...",eventData)
    timestamp = datetime.now().__format__("%Y-%m-%d %H:%M:%S")
    try:
        producer = KafkaProducer(bootstrap_servers=["host:port"])
        data = json.dumps(eventData).encode('utf-8')
        try:

            kafkaResponse = producer.send('streamTest', data)

            response ={'time': str(timestamp), 'kafkaResponse':kafkaResponse.get(), 
                       'postResult': 'true'}
            print('kafaka response is...', response)
        except ConnectionAbortedError:
                response ={'time': str(timestamp), 'postResult': 'false'}
        except kafka.errors.KafkaTimeoutError:
                response ={'time': str(timestamp), 'postResult': 'false'}
        print('kafaka response is...', response)
        return response
    except kafka.errors.NoBrokersAvailable:
        response = {'Response':'Kafka Errors... NoBrokersAvailable'}
        print('kafaka response ', response)
        return response
