The custom pattern is used for specifying an HTTP method that is not included in the pattern field, such as HEAD, or “*“ to leave the HTTP method unspecified for this rule. The wild-card rule is useful for services that provide content to Web (HTML) clients.
body
string
The name of the request field whose value is mapped to the HTTP request body, or * for mapping all request fields not captured by the path pattern to the HTTP body, or omitted for not having any HTTP request body. NOTE: the referred field must be present at the top-level of the request message type.
response_body
string
Optional. The name of the response field whose value is mapped to the HTTP response body. When omitted, the entire response message will be used as the HTTP response body. NOTE: The referred field must be present at the top-level of the response message type.
Additional HTTP bindings for the selector. Nested bindings must not contain an additional_bindings field themselves (that is, the nesting may only be one level deep).
