AI-generated Key Takeaways
-
HttpBody
is a message type used to represent arbitrary HTTP request or response bodies, especially for non-JSON formats like raw binary or HTML. -
It can be used with both streaming and non-streaming API methods, and as a top-level request field for easier parameter extraction.
-
HttpBody
includes fields for content type, raw data (base64-encoded), and application-specific extensions. -
Using
HttpBody
only affects how request/response bodies are handled, leaving other API features unchanged.
Resource: HttpBody
Message that represents an arbitrary HTTP body. It should only be used for payload formats that can't be represented as JSON, such as raw binary or an HTML page.
This message can be used both in streaming and non-streaming API methods in the request as well as the response.
It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body.
Example:
message GetResourceRequest {
// A unique request id.
string requestId = 1;
// The raw HTTP body is bound to this field.
google.api.HttpBody http_body = 2;
}
service ResourceService {
rpc GetResource(GetResourceRequest)
returns (google.api.HttpBody);
rpc UpdateResource(google.api.HttpBody)
returns (google.protobuf.Empty);
}
Example with streaming methods:
service CaldavService {
rpc GetCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);
rpc UpdateCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);
}
Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.
