RevokeRole()

This method revokes the role of a specific 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) RevokeRole(ctx context.Context, opt RevokeRoleOption, 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.	RevokeRoleOption
callOpts	Optional parameters for calling the methods.	grpc.CallOption

RevokeRoleOption

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

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

Example

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

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

opts := client.NewRevokeRoleOption(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.RevokeRole(context.Background(), opts, callOpts)
