Invalid uid

Error message

Invalid uid

What it means

Thrown by the ZCOOL user route when the `:uid` path parameter is non-numeric (so it is treated as a personal-domain subdomain prefix) but fails `isValidHost`. The route accepts either a numeric user ID (`/zcool/user/568339`) or a subdomain-style alias (`/zcool/user/baiyong`); a value that is neither a number nor a valid host label is rejected.

Solutions

1. Use only the bare alias or numeric ID: `/zcool/user/baiyong` or `/zcool/user/568339`.
2. If you have a full profile URL, extract the subdomain prefix (`baiyong` from `baiyong.zcool.com.cn`) or the numeric segment before calling the route.
3. Strip any leading/trailing slashes or protocol before passing the value as `uid`.

Example fix

// before — caller passes a full URL segment
// GET /zcool/user/https://baiyong.zcool.com.cn  -> Invalid uid
// after — pass the bare alias or numeric id
// GET /zcool/user/baiyong
// GET /zcool/user/568339

function normalizeZcoolUid(raw) {
    // numeric id
    if (/^\d+$/.test(raw)) return raw;
    // subdomain alias extracted from a full URL
    const m = raw.match(/^(?:https?:\/\/)?([a-z0-9-]+)\.zcool\.com\.cn/i);
    if (m) return m[1];
    // bare alias
    if (/^[a-z0-9-]+$/i.test(raw)) return raw;
    throw new Error(`Invalid zcool uid: ${raw}`);
}

function isValidZcoolUid(uid: string): boolean {
    return /^\d+$/.test(uid) || /^[a-z0-9-]+$/i.test(uid);
}

When it happens

Trigger: The caller supplies a `uid` that is not all-digits and is not a valid DNS host label — e.g. contains slashes, spaces, dots, or special characters; or a copy-paste of a full URL instead of the bare alias.

Common situations: User pastes `https://baiyong.zcool.com.cn` or `www.zcool.com.cn/u/568339` into the path instead of just `baiyong` / `568339`; a malformed client request injects unexpected characters into the param.
