`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;
any.PackFrom(foo);
...
if (any.UnpackTo(&foo)) {
  ...
}

Example 2: Pack and unpack a message in Java.

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

Example 3: Pack and unpack a message in Python.

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

Example 4: Pack and unpack a message in Go

 foo := &pb.Foo{...}
 any, err := ptypes.MarshalAny(foo)
 ...
 foo := &pb.Foo}
 if err := ptypes.UnmarshalAny(any, foo); err != nil {
   ...
 }

The pack methods provided by protobuf library will by default use
'type.googleapis.com/full.type.name' as the type URL and the unpack
methods only use the fully qualified type name after the last '/'
in the type URL, for example "foo.bar.com/x/y.z" 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": "type.googleapis.com/google.profile.Person",
  "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 &#64;type
field. Example (for message [google.protobuf.Duration][]):

{
  "&#64;type": "type.googleapis.com/google.protobuf.Duration",
  "value": "1.212s"
}

    public Google\Protobuf\Internal\Message::discardUnknownFields()
    public getTypeUrl()
     
    A URL/resource name that uniquely identifies the type of the serialized protocol buffer message. 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).

    In practice, teams usually precompile into the binary all types that they
    expect it to use in the context of Any. However, for URLs which use the
    scheme http, https, or no scheme, one can optionally set up a type
    server that maps type URLs to message definitions as follows:

    • If no scheme is provided, https is assumed.
    • 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.)
      Note: this functionality is not currently available in the official
      protobuf release, and it is not used for type URLs beginning with
      type.googleapis.com.
      Schemes other than http, https (or the empty scheme) might be
      used with implementation specific semantics.
