不同流中的HTTP请求响应

Question

目前我正在与Mule合作并需要做类似的事情：

- 流程更新 -

http端点是请求 - 响应（不是单向）。我的意思是，我想在RequestFlow中查询我的http请求，并从ServiceResponse中的http获取响应。

怎么做？谢谢你的帮助。

- 添加了XML配置（请求 - 更新标记已更新）

- 错误更新 -

在我更改流程并使用回复响应路由消息后，我尝试调试流程。我发现了一些奇怪的东西。当调试器到达

时

  

请求 - 应答

组件，它会自动返回

  

表达

组件（循环）。我该如何解决？

要实现目标，您需要：

• 将RequestFlow中的HTTP端点设为request-response，
• 使用request-reply routing message processor对WMQ执行异步操作，同时屏蔽RequestFlow，直到响应来自ZKSEAP OUT。
