add_header Method

Adds a custom header to send with outgoing messages.

Syntax

def add_header(key: str, value: str) -> None: ...

Remarks

This method is used to add user-defined headers to the list of headers held by the Header* properties.

When send_message or send_data is called, all headers in the Header* properties are added to the outgoing message.

Note that the STOMP specification defines a number of standard headers necessary for implementing the STOMP protocol. When constructing an outgoing message, the class silently ignores any user-defined headers that are already set by the class.
