MessageEnd.tail

Description

Protocol-dependent message footer.

For each protocol

The content of tail can vary depending on the protocol used by the message.

HTTP

A chunked HTTP message has an optional trailer where extra header fields can be transferred at the end of the message. These header fields, if any, can be accessed via headers property of the tail object.

MQTT

A MQTT packet has no meta-info in its tail, therefore the property is always null.

Thrift

A Thrift message can have the decoded struct in the payload property of the tail object if decodeThrift() has its paylaod option set to true.

Dubbo

A Dubbo message has no meta-info in its tail, therefore the property is always null.

Syntax

messageEnd.tail
