Upper snake case values

This rule enforces that all Get RPCs have a response message of the resource, as mandated in AIP-131.

Details

This rule looks at any message matching beginning with Get, and complains if the name of the corresponding output message does not match the name of the RPC with the prefix Get removed.

Examples

Incorrect code for this rule:

// Incorrect.
rpc GetBook(GetBookRequest) returns (GetBookResponse) {  // Should be `Book`.
  option (google.api.http) = {
    get: "/v1/{name=publishers/*/books/*}"
  };
}

Correct code for this rule:

// Correct.
rpc GetBook(GetBookRequest) returns (Book) {
  option (google.api.http) = {
    get: "/v1/{name=publishers/*/books/*}"
  };
}

Disabling

If you need to violate this rule, use a leading comment above the method. Remember to also include an aip.dev/not-precedent comment explaining why.

// (-- api-linter: core::0131::response-message-name=disabled
//     aip.dev/not-precedent: We need to do this because reasons. --)
rpc GetBook(GetBookRequest) returns (GetBookResponse) {
  option (google.api.http) = {
    get: "/v1/{name=publishers/*/books/*}"
  };
}

If you need to violate this rule for an entire file, place the comment at the top of the file.
