FQL v4 will be decommissioned on June 30, 2025. Ensure that you complete your migration from FQL v4 to FQL v10 by that date.

Fauna accounts created after August 21, 2024 must use FQL v10. These accounts will not be able to run FQL v4 queries or access the v4 Dashboard.

For more details, see the v4 EOL announcement and migration guide. Contact support@fauna.com with any questions.

Get a token

Problem

You need to retrieve a token from the current database.

Solution

Use the Get function:

client.query(
  q.Get(q.Ref(q.Tokens(), '1'))
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))

{
  ref: Ref(Tokens(), "1"),
  ts: 1631739421230000,
  instance: Ref(Collection("users"), "1"),
  hashed_secret: '$2a$05$HgbE0YEse2i7.5F4a5MHm.wGDmk4C3kMrP7NJpP40GrO06DgP584q'
}

result = client.query(
  q.get(q.ref(q.tokens(), "1"))
)
print(result)

{'ref': Ref(id=1, collection=Ref(id=tokens)), 'ts': 1631739698710000, 'instance': Ref(id=1, collection=Ref(id=users, collection=Ref(id=collections))), 'hashed_secret': '$2a$05$HExlDNKKmJP69pnpzVmf1.nsTDOJ5FbgfwUv9z1CXg./nQBsT70ny'}

result, err := client.Query(
	f.Get(f.Ref(f.Tokens(), "1")))

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

map[hashed_secret:$2a$05$a77WPbm2U.Ms6GSw6oNp5uOZMefME5e.hLQxIhsgh/h2ceKQpxS8W instance:{1 0xc000180660 0xc000180660 <nil>} ref:{1 0xc0001804b0 0xc0001804b0 <nil>} ts:1631739851370000]

try
{
    Value result = await client.Query(
        Get(Ref(Tokens(), "1"))
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}

ObjectV(ref: RefV(id = "1", collection = RefV(id = "tokens")),ts: LongV(1631740104780000),instance: RefV(id = "1", collection = RefV(id = "users", collection = RefV(id = "collections"))),hashed_secret: StringV($2a$05$ido9qqXfQ.KjpZQLfGqYJup/kilkj9Vqka3Yuzx//oPpjsJw69QHO))

System.out.println(
    client.query(
        Get(Ref(Tokens(), "1"))
    ).get());

{ref: ref(id = "1", collection = ref(id = "tokens")), ts: 1631740269380000, instance: ref(id = "1", collection = ref(id = "users", collection = ref(id = "collections"))), hashed_secret: "$2a$05$iJNG63lEeIwJum933SCCee/lqssvYlETxzVOiUeWK/BiLazjGsbgC"}

Get(Ref(Tokens(), "1"))

{
  ref: Ref(Tokens(), "1"),
  ts: 1631738649530000,
  instance: Ref(Collection("users"), "1"),
  hashed_secret: '$2a$05$jr3cTMQcY.mKNNizVlQIZOpIC3wVjvxuse93/FDw9A9JbX9.9lIoy'

Discussion

Once a key has been created, its secret is only displayed at that time. Afterwards, it is no longer possible to retrieve the key’s secret. If you have lost the secret associated with a key, delete the key and create a new one.
