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.	No
ULBId	string	Traditional Load Balancer Instance ID	Yes
VServerName	string	VServer instance name, default is 'VServer'.	No
ListenType	string	Listener type, enumeration value, RequestProxy, request proxy; PacketsTransmit, packet forwarding. The default is RequestProxy.	No
Protocol	string	The protocol of the VServer instance, under the request proxy mode there are HTTP, HTTPS, TCP, under the message forwarding mode there are TCP, UDP. The default is 'HTTP'.	No
FrontendPort	int	VServer backend port, value range [1-65535]; default value is 80	No
Method	string	VServer load balancing mode, enumeration values: Roundrobin -> Round Robin; Source -> Source Address; ConsistentHash -> Consistent Hashing; SourcePort -> Source Address (Calculate Port); ConsistentHashPort -> Consistent Hashing (Calculate Port); WeightRoundrobin -> Weighted Round Robin; Leastconn -> Least Connections; Backup -> Master-Slave Mode. ConsistentHash, SourcePort, ConsistentHashPort are only used in packet forwarding; Leastconn is only used in request proxy; Roundrobin, Source, and WeightRoundrobin, Backup are used in both request proxy and packet forwarding. The default is: "Roundrobin".	No
PersistenceType	string	VServer session persistence mode, session persistence is turned off by default. Enumerated values: None -> Off; ServerInsert -> Automatically generate KEY; UserDefined -> User-defined KEY.	No
PersistenceInfo	string	Confirm according to PersistenceType; None and ServerInsert: This field is meaningless; UserDefined: This field passes in a custom session hold String	No
ClientTimeout	int	When ListenType is RequestProxy, it represents the recovery time of idle connections, unit: seconds, value range: time (0, 86400], default value is 60; When ListenType is PacketsTransmit, it represents the connection holding time, unit: seconds, value range: [60, 900], 0 means disabling connection holding.	No
MonitorType	string	Health check type, enumeration values: Port -> Port check; Path -> Path check; Ping -> Ping detection; Customize -> UDP check The default value for request proxy type is Port, where TCP protocol only supports Port, other protocols support Port and Path; For message forwarding type, TCP protocol only supports Port, UDP protocol supports Ping, Port and Customize, the default value is Ping.	No
Domain	string	Confirm according to MonitorType; When MonitorType is Path, this field is meaningful, representing HTTP check domain.	No
Path	string	Confirm according to MonitorType; When MonitorType is Path, this field is meaningful, representing the HTTP check path.	No
RequestMsg	string	Confirm according to MonitorType; When MonitorType is Customize, this field is meaningful, representing the request message sent by UDP check.	No
ResponseMsg	string	Confirm according to MonitorType; When MonitorType is Customize, this field is meaningful, representing the response message that the UDP check request should receive.	No
SecurityPolicyId	string	Security policy group ID, default value 'Default'	No
EnableCompression	int	0: Off 1: On, used for data compression function	No
ForwardPort	int	Redirect port, value range [0-65535]; the default value is 0, representing closure; only the HTTP protocol supports the opening of the redirect function.	No
EnableHTTP2	int	0: Off 1: On, used to enable the http2 feature; the default value is 0	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
VServerId	string	Id of the VServer instance	No
