List of Transport Layer Applications

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • For mandatory resource types, indicate with a prefix of * .
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Applicationsarray<object>

List of transport layer applications.

itemobject

Details of the transport layer application.

Rulesarray<object>

List of forwarding rules.

item1object

Details of the forwarding rule.

Protocolstring

Forwarding rule protocol, with values:

  • TCP: TCP protocol.
  • UDP: UDP protocol.
TCP
EdgePortstring

Edge port. Supports:

  • A single port, e.g., 80.
  • Port range, e.g., 81-85, representing ports 81, 82, 83, 84, 85.
  • Combination of ports and port ranges, separated by commas, e.g., 80,81-85,90, representing ports 80, 81, 82, 83, 84, 85, 90.
80
SourcePortstring

Source port. Supports:

  • A single port, when the source port is a single port, any valid combination of edge ports is supported.
  • Port range, only when the edge port is a port range, the source port can be set to a port range, and the range size must be consistent with the edge port. For example, if the edge port is 90-93, the source port cannot be set to 81-85 because the source port range is 5 and the edge port range is 3, which are inconsistent.
80
Sourcestring

Specific value of the source, which needs to match the source type.
