1. API Description

This API (SetQueueAttributes) is used to modify the attributes of a message queue. Note that you cannot modify the name of a queue.

Domain for public network API

Domain for private network API

  • region should be replaced by specific region: gz (Guangzhou), sh (Shanghai), bj (Beijing). The region value in the common parameter should be kept consistent with the one of the domain. In case of inconsistency, the domain region should prevail. The request should be sent to the region specified by the domain.
  • Requests for accessing via public network domain support both HTTP and HTTPS. Requests for accessing via private network only support HTTP.
  • Some of the input parameters are optional, so the default values are not required.
  • All output parameters will be returned to the user when the request is successful; otherwise, at least code, message, and requestId will be returned.
