Delete methods: No HTTP body

This rule enforces that all Delete RPCs omit the HTTP body, as mandated in AIP-135.

Details

This rule looks at any message matching beginning with Delete, and complains if the HTTP body field is set.

Examples

Incorrect code for this rule:

// Incorrect.
rpc DeleteBook(DeleteBookRequest) returns (google.protobuf.Empty) {
  option (google.api.http) = {
    delete: "/v1/{name=publishers/*/books/*}"
    body: "*"  // This should be absent.
  };
}

Correct code for this rule:

// Correct.
rpc DeleteBook(DeleteBookRequest) returns (google.protobuf.Empty) {
  option (google.api.http) = {
    delete: "/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::0135::http-body=disabled
//     aip.dev/not-precedent: We need to do this because reasons. --)
rpc DeleteBook(DeleteBookRequest) returns (google.protobuf.Empty) {
  option (google.api.http) = {
    delete: "/v1/{name=publishers/*/books/*}"
    body: "*"
  };
}

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