Error message

Fanfou RSS is disabled due to the lack of <a href="https://docs.rsshub.app/deploy/config#route-specific-configurations">relevant config</a>

What it means

Thrown by the fanfou public-timeline route when any of config.fanfou.consumer_key, consumer_secret, username, or password is missing. The public search endpoint still requires authenticated OAuth credentials in fanfou's model.

FANFOU_CONSUMER_SECRET=...
FANFOU_USERNAME=...
FANFOU_PASSWORD=...

Defensive patterns

Strategy: validation

Validate before calling

const f = config.fanfou;
const ok = f && f.consumer_key && f.consumer_secret && f.username && f.password;
if (!ok) throw new Error('Fanfou RSS is disabled ...');

Type guard

const isFanfouConfigured = (c: any): boolean =>
  !!c?.fanfou?.consumer_key && !!c?.fanfou?.consumer_secret &&
  !!c?.fanfou?.username && !!c?.fanfou?.password;

Prevention

Set all four FANFOU_* vars together.
Keep fanfou routes behind the same config guard used by the other fanfou routes.

When it happens

Trigger: Any of the four FANFOU_* env vars is unset when /fanfou/public-timeline/:keyword is requested.

Common situations: Optional fanfou config omitted, partial, or renamed.
