You can call this operation to query the consumption status of a message based on a specified message ID.

This operation is implemented based on the internal offset mechanism of Message Queue for Apache RocketMQ. The results are correct in most cases. However, if you have reset the offset or cleared messages, the results may be incorrect.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
