您可以通过Mule Client调用HTTP入站，这是一个示例:
You can invoke the HTTP Inbound through Mule Client, here is an example:
MuleClient muleClient = new MuleClient(muleContext);
Map<String, Object> headers = new HashMap<String, Object>(1);
headers.put("key", "456453N123");
MuleMessage result = muleClient.send("http://localhost:8081/prm", PAYLOAD, headers);
HTTP头位于MuleMessage的入站范围属性中.要从流中获取标题，可以使用:
The HTTP headers are in the inbound-scoped properties of the MuleMessage. To get the header from a flow, you can use:
<logger level="INFO" message="Header Content-Type = #[header:key]"/>
