基于ServiceBus触发Azure函数并写回不工作(Python)

问题描述

我有一个Python Azure函数，它根据主题的消息触发，它独立工作得很好。然而，如果我随后尝试将消息也写入到不同的ServiceBus队列中，它将不起作用(因为在Azure函数中，如果将新消息发布到主题，甚至不会触发)。当我包含msg_out: func.Out[str]组件时，感觉触发器条件不满足。如有任何帮助，我们将不胜感激！

__init.py

import logging
import azure.functions as func

def main(msg: func.ServiceBusMessage, msg_out: func.Out[str]):
    # Log the Service Bus Message as plaintext

    # logging.info("Python ServiceBus topic trigger processed message.")
    logging.info("Changes are coming through!")
   
    msg_out.set("Send an email")

    {

      "subscriptionName": "validation-sub",
      "connection": "Test_SERVICEBUS"
    },
    {

      "connection": "Test_SERVICEBUS",
      "name": "msg_out",
      "queueName": "email-test"
    }
  ]
}

解决方案

我可以重现您的问题，这似乎是由以下错误引起的：

不允许使用属性essionHandlerOptions。

删除sessionHandlerOptions可以正常触发。
