support http rule '/v1/{name=messages/*}'

[kenix]

Most probably via SimpleUrlHandlerMapping, for http.proto:

// Example:
//
//     service Messaging {
//       rpc GetMessage(GetMessageRequest) returns (Message) {
//         option (google.api.http) = {
//             get: "/v1/{name=messages/*}"
//         };
//       }
//     }
//     message GetMessageRequest {
//       string name = 1; // Mapped to URL path.
//     }
//     message Message {
//       string text = 1; // The resource content.
//     }
//
// This enables an HTTP REST to gRPC mapping as below:
//
// HTTP | gRPC
// -----|-----
// `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
