Mengkueri semua paket yang disimpan dalam topik tertentu dalam rentang pengatur waktu tertentu per halaman.
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 you do not know the ID or key of a message that you want to query, you can call this operation to query all messages that are stored in the topic within a specified time range. The results are displayed by page.
-
We recommend that you specify a short time range to query messages. If you specify a long time range, a large number of messages are returned. In this case, you cannot find the message that you want to query in an efficient manner. You can perform the following steps to query messages:
Perform a paged query by specifying the topic, start time, end time, and number of entries to return on each page. If the topic contains messages, the information about the messages on the first page, total number of pages, and task ID are returned by default.
Specify the task ID and a page number to call this operation again to query the messages on the specified page. The BeginTime, EndTime, and PageSize parameters do not take effect. By default, the system uses the values of these parameters that you specified in the request when you created the specified query task.
