Run methods: HTTP body

This rule enforces that all Run RPCs use * as the HTTP body, as mandated in AIP-152.

Details

This rule looks at any RPC methods beginning with Run, and complains if the HTTP body field is anything other than *.

Examples

Incorrect code for this rule:

// Incorrect.
rpc RunWriteBookJob(RunWriteBookJobRequest) returns (google.longrunning.Operation) {
  option (google.api.http) = {
    post: "/v1/{name=publishers/*/writeBookJobs/*}:run"
    body: ""  // The http body should be "*".
  };
  option (google.longrunning.operation_info) = {
    response_type: "RunWriteBookJobResponse"
    metadata_type: "RunWriteBookJobMetadata"
  };
}

Correct code for this rule:

// Correct.
rpc RunWriteBookJob(RunWriteBookJobRequest) returns (google.longrunning.Operation) {
  option (google.api.http) = {
    post: "/v1/{name=publishers/*/writeBookJobs/*}:run"
    body: "*"
  };
  option (google.longrunning.operation_info) = {
    response_type: "RunWriteBookJobResponse"
    metadata_type: "RunWriteBookJobMetadata"
  };
}

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::0152::http-body=disabled
//     aip.dev/not-precedent: We need to do this because reasons. --)
rpc RunWriteBookJob(RunWriteBookJobRequest) returns (google.longrunning.Operation) {
  option (google.api.http) = {
    post: "/v1/{name=publishers/*/writeBookJobs/*}:run"
    body: ""
  };
  option (google.longrunning.operation_info) = {
    response_type: "RunWriteBookJobResponse"
    metadata_type: "RunWriteBookJobMetadata"
  };
}

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