标签的意思是，您在那里输入的任何内容都将被输入到您的http:inbound endpoint
响应中。由于smtp是异步的，它将在响应阶段被忽略，并且块将返回它从自定义转换器获得的任何内容
解决方案是将
块中的内容移动到
块中，这样您的自定义转换器就不会干扰http响应。在
块中，您只需要一个
就可以将http:outbound端点
转换为字符串
编辑：
将
移动到http:outbound端点之后，并将转换器更改为获取字符串，而不是输入流。否则，一旦两个读卡器中的任何一个读取了输入流，输入流就会关闭。在此之后，您将不需要
。您的需求正是mule请求者模块所基于的：
示例项目：
此模块允许您异步执行两件事情
希望这有帮助感谢您的快速响应，我根据您的建议更改了我的流，并从HTTP获得JSON响应，但smtp我收到一封空电子邮件，看起来自定义转换器可以读取输入流，该输入流在转换之前关闭。对象：org.mule.transport.HTTP。ReleasingInputStream@684be8b8 org.mule.api.transformer.TransformerException:无法读取InputStream。在org.mule.transformer.simple.ObjectToString.createStringFromInputStream（ObjectToString.java:87）在org.mule.transformer.simple.ObjectToString.doTransform（ObjectToString.java:58）对不起，我的错。同一个流不能读取两次。更新了答案。感谢圣战者。我们的要求是http出站（请求/响应）是实时的SMTP是异步的。这个合适吗。我确信这一要求相当普遍。这种情况非常类似于通过web下订单。请求者立即看到http响应（请求/响应），并且响应以电子邮件的形式发送（异步）。虽然我没有尝试使用http端点，但听起来是可能的。我做了一些类似的事情，只是用jms和异步读取sftp位置的一种方法。
