示例1: while

  let nextUrl = meta.nextUrl

  // Check if nextUrl is taken
  let exists = (await db.collection('links').doc(nextUrl).get()).exists;
  while (exists) {
    // Incremement nextUrl until we find an open link
    nextUrl = base62Encode(base62Decode(nextUrl) + 1);
    exists = (await db.collection('links').doc(nextUrl).get()).exists;
  }

  // Update db with new nextUrl
  await db.doc('meta/meta').update({nextUrl: nextUrl});
}

export const onLinkCreateIncrementNextUrl =
    functions.firestore.document('links/{linkId}')
        .onCreate(async (_snapshot, _context) => {
          await updateNextUrl();
        });

export const callableIncrementNextUrl =
    functions.https.onCall(async (_data, _context) => {
      await updateNextUrl();
    })

// Increment the hit count for the given short link. If the hits field does not
// exist on the link, it is created. If a v1Hits field exists on the link
// (legacy hit count), then its value is added to the hits field and the v1Hits
// field is deleted.
// This function is NOT idempotent.
