Public Parameters

Parameter Name	Type	Description Information	Required
Action	string	Corresponding API command name, the current API is `AddTargets`.	Yes
PublicKey	string	The user’s public key can be obtained from Console	Yes
Signature	string	User signature generated based on public key and API command, see Signature Algorithm	Yes

Request Parameters

Parameter Name	Type	Description Information	Required
Region	string	Region. See List of Regions and Availability Zones	Yes
ProjectId	string	Project ID. If not filled in, the default project is used, sub-accounts must be filled in. Please refer to the GetProjectList interface.	Yes
LoadBalancerId	string	ID of the Load Balancing Instance	Yes
ListenerId	string	Listener’s ID	Yes
Targets.N.ResourceType	string	Type of service node. Limited enumeration values: “UHost” / “UNI”/“UPM”/“IP”, default value: “UHost”; For non-IP types, if the resource has multiple IPs, only the main IP can be added; For non-IP types, related resource information will be displayed when shown, while IP types only display IP information. When the related resource is deleted, non-IP types will remove the related resource from the load balancer, but this logic is not guaranteed for IP types.	No
Targets.N.ResourceId	string	Resource ID of the service node. Must be passed when not of IP type.	No
Targets.N.VPCId	string	The VPC resource ID of the service node. It is required when the IP type is passed.	No
Targets.N.SubnetId	string	The subnet resource ID of the service node. Must be passed when the IP type is used.	No
Targets.N.ResourceIP	string	IP of the service node. Must be provided when the IP type is set.	No
Targets.N.Port	int	Port of the service node. Limited value range: [1-65535], default value is 80	No
Targets.N.Weight	int	The weight of the service node. Limited value range: [1-100], default value is 1; only effective in weighted round-robin algorithm.	No
Targets.N.Enabled	boolean	Is the service node enabled? The default value is true.	No
Targets.N.IsBackup	boolean	Is the service node a backup node? The default value is false.	No

Response Field

Field Name	Type	Description Information	Required
RetCode	int	Return status code. If it is 0, it means successful return. If it is not 0, it means failure.	Yes
Action	string	Operation command name.	Yes
Message	string	Returns an error message, providing detailed description when `RetCode` is non-zero.	No
Targets	array[TargetSet]	Service Node Information	No

Data Model

TargetSet

Field Name	Type	Description Information	Required
ResourceType	string	Type of service node. Limited enumeration values: UHost -> Cloud Host, UNI -> Virtual Network Interface, UPM -> Physical Cloud Host, IP -> IP type; Default value: “UHost”; For non-IP types, if the resource has multiple IPs, only the main IP can be added; For non-IP types, related resource information will be displayed during the presentation, while IP type only displays IP information. When the related resource is deleted, the non-IP type will remove the related resources from the lb, but the IP type does not guarantee this logic.	No
ResourceId	string	Resource ID of the service node. Must be passed when not of IP type.	No
VPCId	string	The VPC resource ID of the service node. It is required when the IP type is passed.	No
SubnetId	string	The subnet resource ID of the service node. Must be passed when the IP type is used.	No
ResourceIP	string	IP of the service node. Must be provided when the IP type is set.	No
Port	int	Port of the service node. Limited value range: [1-65535]; Default value: 80	No
Weight	int	The weight of the service node. Limited value range: [1-100]; Only effective when using the weighted round-robin algorithm; Default value: 1.	No
Enabled	boolean	Is the service node enabled? Default value: true	No
IsBackup	boolean	Is the service node a backup node. Default value: false	No
Id	string	Identification ID of the service node.	No
State	string	Health check status of the service node. Limited enumeration values: Healthy -> Healthy, Unhealthy -> Unhealthy.	No
