rpc-operation-request-body

Full name

@azure-tools/typespec-azure-core/rpc-operation-request-body

Validates that RpcOperation request bodies are used correctly. Operations using HTTP verbs that do not support a body (like GET or DELETE) should not define one.

Note

This rule only applies to @get and @delete operations. Other HTTP verbs like @post, @put, and @patch can have request bodies.

❌ Incorrect

GET operation with a request body:

@get
op getWidget is RpcOperation<
  {
    @body body: Widget;
  },
  Widget
>;

DELETE operation with a request body:

@delete
op deleteWidget is RpcOperation<
  {
    @body body: Widget;
  },
  Widget
>;

✅ Correct

GET operation with no body:

@get
op getWidget is RpcOperation<{}, Widget>;

DELETE operation with no body:

@delete
op deleteWidget is RpcOperation<{}, Widget>;

GET/DELETE with query parameters using @bodyIgnore:

@get
op get is RpcOperation<
  {
    @bodyIgnore options: {
      @query foo: string;
    };
  },
  {}
>;

POST operation with a body:

@post
op createWidget is RpcOperation<
  {
    @body body: Widget;
  },
  Widget
>;
