Description

The HasCurrentIdentity function returns true if the current client authentication credentials have an associated identity, and false if they don’t.

When authentication is performed by an identity provider, HasCurrentIdentity returns true if the associated JWT has a sub field.

Parameters

None.

Returns

A boolean indicating whether the current client credentials are associated with an identity/JWT.

Examples

The following query is run in the context of a logged-in Fauna user:

client.query(
  q.HasCurrentIdentity()
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
false
result = client.query(
  q.has_current_identity()
)
print(result)
False
result, err := client.Query(
	f.HasCurrentIdentity())

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
false
try
{
    Value result = await client.Query(
        HasCurrentIdentity()
    );

    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
BooleanV(False)
System.out.println(
    client.query(
        HasCurrentIdentity()
    ).get());
