Pushes a message to a specified consumer.

Usage notes

This operation is used to verify the message consumption status. This operation obtains the message body based on the input MsgId parameter, re-encapsulates the message body, and then pushes the message body to the consumer. The resent message has the same content as the original message. However, the two messages are not the same. The values of the MsgId parameter for the two messages are different.
