<code>CurrentToken</code>

Description

The CurrentToken function returns information about the active authentication:

When a token is used, a Reference to the token document is returned.
When a key is used, and the key exists in the current database (and not in a parent database), a Reference to the key document is returned.
When authentication is performed by an identity provider, an object containing the active JWT’s claims is returned.

For all other cases, CurrentToken emits an error. These cases include:

Authentication uses the "root" Fauna secret.
Authentication uses a key that has the database field set.
Authentication uses a key that exists in a parent database, for example, when using a scoped key.

Parameters

None.

Returns

For tokens, and keys defined in the current database, a Reference to the associated token/key.

For JWTs, an object containing the claims from the active JWT.

For connections using the "root" Fauna key, or a key that has the database field defined, an error is returned.

Examples

The following query runs in the context of a Fauna token:

try
{
    Value result = await client.Query(
        CurrentToken()
    );

    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}

RefV(id = "1", collection = RefV(id = "tokens"))

result, err := client.Query(
	f.CurrentToken())

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}

{1 0xc000200210 0xc000200210 <nil>}

System.out.println(
    client.query(
        CurrentToken()
    ).get());

ref(id = "1", collection = ref(id = "tokens"))

client.query(
  q.CurrentToken()
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
