Function

Calling Method

For details, see Calling APIs.

URI

PUT /v2/rabbitmq/{project_id}/instances/{instance_id}/vhosts/{vhost}/queues

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details, see Obtaining a Project ID.
instance_id	Yes	String	Instance ID.
vhost	Yes	String	Virtual host name. If the name contains a slash (/), replace it with __F_SLASH__. Otherwise, the calling fails. For example, if the virtual host name is /test, the input parameter is __F_SLASH__test.

Request Parameters

**Table 2** Request body parameters
Parameter	Mandatory	Type	Description
name	Yes	String	Queue name.
auto_delete	Yes	Boolean	Indicates whether to enable automatic deletion.
durable	No	Boolean	Indicates whether to enable data persistence (The AMQP version does not have this field because data persistence is enabled by default).
dead_letter_exchange	No	String	Name of the dead letter exchange. Rejected and expired messages are re-sent to this exchange.
dead_letter_routing_key	No	String	Routing key of the dead letter exchange. The dead letter exchange sends dead letter messages to the queue with a matching routing key.
message_ttl	No	Long	Indicates for how long a message in this queue can be retained.
lazy_mode	No	String	To make this queue lazy, enter lazy. Lazy queues store more messages on disk and save memory. If this parameter is not set, messages are stored in memory and delivered quickly. (AMQP stores messages to disks by default. This field is not involved.)
