GrantRole()

This method grants a role to a user. In Milvus, you can allocate multiple privileges or privilege groups to a role and grant the role to a user so that the user gains the privileges allocated to the role.

func (c *Client) GrantRole(ctx context.Context, opt GrantRoleOption, callOpts ...grpc.CallOption) error

Request Parameters

Parameter	Description	Type
ctx	Context for the current call to work.	context.Context
opt	Optional parameters of the methods.	GrantRoleOption
callOpts	Optional parameters for calling the methods.	grpc.CallOption

GrantRoleOption

This is an interface type. The grantRoleOption struct type implements this interface type.

You can use the NewGrantRoleOption() function to get the concrete implementation.

NewGrantRoleOption

The signature of the NewGrantRoleOption() is as follows:

func NewGrantRoleOption(userName, roleName string) *grantRoleOption

Parameter	Description	Type
userName	Name of the target user of this operation.	string
roleName	Name of the role to grant.	string

grpc.CallOption

This interface provided by the gRPC Go library allows you to specify additional options or configurations when making requests. For possible implementations of this interface, refer to this file.

Example

import (
   "context"
   "google.golang.org/grpc"
   "github.com/milvus-io/milvus/v2/milvusclient"
)

roleName := "my_role"
userName := "my_user"

opts := client.NewGrantRoleOption(roleName, userName)

onFinish := func(ctx context.Context, err error) {
    if err != nil {
        fmt.Printf("gRPC call finished with error: %v\n", err)
    } else {
        fmt.Printf("gRPC call finished successfully")
    }
}

callOption := grpc.OnFinish(onFinish)

err := mclient.GrantRole(context.Background(), opts, callOpts)
