Mengkueri informasi tentang Paket dengan menentukan ID Paket dan mengetahui apakah Paket telah dikonsumsi.
Deskripsi operasi
API operations provided by Alibaba Cloud are used to manage and query resources of Alibaba Cloud services. We recommend that you integrate these API operations only in management systems. Do not use these API operations in the core system of messaging services. Otherwise, system risks may occur.
If a message is not consumed as expected, you can call this operation to query the information about the message for troubleshooting.
This operation uses the exact match method to query a message based on the message ID. You can obtain the message ID from the SendResult parameter that is returned after the message is sent. You must store the returned information after each message is sent. The queried information about a message includes the point in time when the message was sent, the broker on which the message is stored, and the attributes of the message such as the message key and tag.
