Validator Middleware for Forge Project
This module provides a middleware for Forge to validate request parameters, using schema defined in .proto files.
The middleware validates requests with the schema definitions and validation functions provided by Protovalidate.
Protovalidate requires no validation code generation at build time. The middleware also invokes Validate() error
when a request implements that interface, so hand-written validators and code generated by other tools participate
without any extra dependency.

Variables ¶
var ErrValidation = errors.MustDefine(errors.KindInvalidArgument, errors.Domain, "VALIDATION_FAILED")
ErrValidation identifies a request rejected by a validator.
Functions ¶
func PerMessageProtoValidateStream ¶
func PerMessageProtoValidateStream() middleware.StreamMiddleware
PerMessageProtoValidateStream validates every message received on a stream.
This suits client and bidirectional streaming, where each message is a separate input worth checking. A message that fails validation fails that RecvMsg with a BadRequest error and leaves the stream open, so the handler decides whether to continue or return. The initial request, when a method has one, is validated too.
func ProtoValidate ¶
func ProtoValidate() middleware.UnaryMiddleware
ProtoValidate is a middleware that validates the request message with protovalidate(https://github.com/bufbuild/protovalidate)
func ProtoValidateStream ¶
func ProtoValidateStream() middleware.StreamMiddleware
ProtoValidateStream validates the initial request of a stream, once, before the handler runs.
This suits server-streaming methods, where the client sends one request and then only receives. For client and bidirectional streaming the initial request is nil and nothing is validated — use PerMessageProtoValidateStream there.
