Overview ¶
Package jsonpb provides marshaling and unmarshaling between protocol buffers and JSON. It follows the specification at https://developers.google.com/protocol-buffers/docs/proto3#json.
This package produces a different output than the standard "encoding/json" package, which does not operate correctly on protocol buffers.

Functions ¶
func Unmarshal ¶
Unmarshal unmarshals a JSON object stream into a protocol buffer. This function is lenient and will decode any options permutations of the related Marshaler.
func UnmarshalNext ¶
UnmarshalNext unmarshals the next protocol buffer from a JSON object stream. This function is lenient and will decode any options permutations of the related Marshaler.
Types ¶
type AnyResolver ¶
AnyResolver takes a type URL, present in an Any message, and resolves it into an instance of the associated message.
type JSONPBmarshaler ¶
JSONPBmarshaler is implemented by protobuf messages that customize the way they are marshaled to JSON. Messages that implement this should also implement JSONPBUnmarshaler so that the custom format can be parsed.
The JSON marshaling must follow the proto to JSON specification:
https://developers.google.com/protocol-buffers/docs/proto3#json
type JSONPBunmarshaler ¶
type JSONPBunmarshaler interface {
UnmarshalJSONPB(*Unmarshaler, []byte) error
}
JSONPBunmarshaler is implemented by protobuf messages that customize the way they are unmarshaled from JSON. Messages that implement this should also implement JSONPBMarshaler so that the custom format can be produced.
The JSON unmarshaling must follow the JSON to proto specification:
https://developers.google.com/protocol-buffers/docs/proto3#json
type Marshaler ¶
type Marshaler struct {
// Whether to render enum values as integers, as opposed to string values.
EnumsAsInts bool
// Whether to render fields with zero values.
EmitDefaults bool
//Enable utf8 bytes to string
EnableUTF8BytesToString bool
// A string to indent each level by. The presence of this field will
// also cause a space to appear between the field separator and
// value, and for newlines to be appear between fields and array
// elements.
Indent string
// Whether to use the original (.proto) name for fields.
OrigName bool
// A custom URL resolver to use when marshaling Any messages to JSON.
// If unset, the default resolution strategy is to extract the
// fully-qualified type name from the type URL and pass that to
// proto.MessageType(string).
AnyResolver AnyResolver
}
Marshaler is a configurable object for converting between protocol buffer objects and a JSON representation for them.
type Unmarshaler ¶
type Unmarshaler struct {
// Whether to allow messages to contain unknown fields, as opposed to
// failing to unmarshal.
AllowUnknownFields bool
//Enable utf8 bytes to string
EnableUTF8BytesToString bool
// A custom URL resolver to use when unmarshaling Any messages from JSON.
// If unset, the default resolution strategy is to extract the
// fully-qualified type name from the type URL and pass that to
// proto.MessageType(string).
AnyResolver AnyResolver
}
Unmarshaler is a configurable object for converting from a JSON representation to a protocol buffer object.
func (*Unmarshaler) Unmarshal ¶
Unmarshal unmarshals a JSON object stream into a protocol buffer. This function is lenient and will decode any options permutations of the related Marshaler.
func (*Unmarshaler) UnmarshalNext ¶
UnmarshalNext unmarshals the next protocol buffer from a JSON object stream. This function is lenient and will decode any options permutations of the related Marshaler.
