Package any

Overview ▾

Package any is a generated protocol buffer package.

It is generated from these files:

It has these top-level messages:


type Any

`Any` contains an arbitrary serialized protocol buffer message along with a URL that describes the type of the serialized message.

Protobuf library provides support to pack/unpack Any values in the form of utility functions or additional generated methods of the Any type.

Example 1: Pack and unpack a message in C++.

Foo foo = ...;
Any any;
if (any.UnpackTo(&foo)) {

Example 2: Pack and unpack a message in Java.

   Foo foo = ...;
   Any any = Any.pack(foo);
   if ( {
     foo = any.unpack(Foo.class);

Example 3: Pack and unpack a message in Python.

   foo = Foo(...)
   any = Any()
   if any.Is(Foo.DESCRIPTOR):

The pack methods provided by protobuf library will by default use '' as the type URL and the unpack methods only use the fully qualified type name after the last '/' in the type URL, for example "" will yield type name "y.z".

JSON ==== The JSON representation of an `Any` value uses the regular representation of the deserialized, embedded message, with an additional field `@type` which contains the type URL. Example:

package google.profile;
message Person {
  string first_name = 1;
  string last_name = 2;

  "@type": "",
  "firstName": <string>,
  "lastName": <string>

If the embedded message type is well-known and has a custom JSON representation, that representation will be embedded adding a field `value` which holds the custom JSON in addition to the `@type` field. Example (for message [google.protobuf.Duration][]):

  "@type": "",
  "value": "1.212s"
type Any struct {
    // A URL/resource name whose content describes the type of the
    // serialized protocol buffer message.
    // For URLs which use the scheme `http`, `https`, or no scheme, the
    // following restrictions and interpretations apply:
    // * If no scheme is provided, `https` is assumed.
    // * The last segment of the URL's path must represent the fully
    //   qualified name of the type (as in `path/google.protobuf.Duration`).
    //   The name should be in a canonical form (e.g., leading "." is
    //   not accepted).
    // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
    //   value in binary format, or produce an error.
    // * Applications are allowed to cache lookup results based on the
    //   URL, or have them precompiled into a binary to avoid any
    //   lookup. Therefore, binary compatibility needs to be preserved
    //   on changes to types. (Use versioned type names to manage
    //   breaking changes.)
    // Schemes other than `http`, `https` (or the empty scheme) might be
    // used with implementation specific semantics.
    TypeUrl string `protobuf:"bytes,1,opt,name=type_url,json=typeUrl" json:"type_url,omitempty"`
    // Must be a valid serialized protocol buffer of the above specified type.
    Value []byte `protobuf:"bytes,2,opt,name=value,proto3" json:"value,omitempty"`
