Description

The HasCurrentToken function returns true if the CurrentToken function would return a value (the reference to an active token or key, or an object representing the claims in an active JWT), or false if CurrentToken would result in an error (when using the "root" Fauna key, or a key that has its database field set).

Parameters

None.

Returns

true when CurrentToken would return a value. false otherwise.

Examples

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

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

    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
BooleanV(True)
result, err := client.Query(
	f.HasCurrentToken())

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
true
System.out.println(
    client.query(
        HasCurrentToken()
    ).get());
true
client.query(
  q.HasCurrentToken()
)
.then((ret) => console.log(ret))
.catch((err) => console.error('Error: %s', err))
true
result = client.query(
  q.has_current_token()
)
print(result)
True
try {
  println(Await.result(
    client.query(
      HasCurrentToken()
    ),
    5.seconds
  ))
} catch {
  case unknown: Throwable => println("Error: " + unknown.getMessage())
}
