Customized Access Control
Kitex provides a simple middleware builder that supports self-defined access control logic to reject requests under certain conditions.
Below is a simple example that randomly rejects 1% of all requests through self-defined access control logic:
package myaccesscontrol
import (
"math/rand"
"github.com/cloudwego/kitex/pkg/acl"
)
var errRejected = errors.New("1% rejected")
// Implements a judge function.
func reject1percent(ctx context.Context, request interface{}) (reason error) {
if rand.Intn(100) == 0 {
return errRejected // an error should be returned when a request is rejected
}
return nil
}
var MyMiddleware = acl.NewACLMiddleware(reject1percent) // create the middleware
Then, you can enable this middleware with WithMiddleware(myaccesscontrol.MyMiddleware)
at the creation of a client or a server.
