Error message

接口错误，错误代码:${responseBody.code},错误原因:${responseBody.msg}

What it means

Thrown when the Nowcoder hot-subject API (type='1', hot discussion topics) returns a response with a non-zero `code` field. RSSHub delegates the upstream API's `code` and `msg` into the thrown Error, so the message contains the original API error. This is a server-side failure from `gw-c.nowcoder.com/api/sparta/subject/hot-subject`, not a client configuration problem.

Solutions

Retry the request after a few minutes — the upstream API may be temporarily overloaded.
Manually open the API URL `https://gw-c.nowcoder.com/api/sparta/subject/hot-subject?limit=20&_=<timestamp>&t=` in a browser to check the live `code`/`msg` values.
If the endpoint was deprecated, check the Nowcoder website for the new API path and update `lib/routes/nowcoder/hots.ts` line 38.
If rate-limited, ensure RSSHub is using `config.trueUA` and consider adding caching via `cache.tryGet`.

Example fix

// before
const responseBody = (await got.get(link)).data;
if (responseBody.code !== 0) {
    throw new Error(`接口错误，错误代码:${responseBody.code},错误原因:${responseBody.msg}`);
}

// after — cache the result to reduce upstream load
const responseBody = await cache.tryGet(link, async () => (await got.get(link)).data);
if (responseBody.code !== 0) {
    throw new Error(`接口错误，错误代码:${responseBody.code},错误原因:${responseBody.msg}`);
}

Defensive patterns

Strategy: retry

Try / catch

// Wrap the upstream API call with retry + cache to absorb transient failures
try {
    const responseBody = await cache.tryGet(link, async () => (await got.get(link)).data);
    if (responseBody.code !== 0) {
        throw new Error(`接口错误，错误代码:${responseBody.code},错误原因:${responseBody.msg}`);
    }
} catch (e) {
    logger.error(`Nowcoder hot-subject API failed: ${e}`);
    throw e;
}

Prevention

Cache upstream API responses with cache.tryGet to reduce repeated calls.
Monitor the nowcoder API endpoint for deprecation notices.
Use config.trueUA for realistic browser headers.

When it happens

Trigger: Calling the nowcoder hots route with type '1' (or default) when the upstream Nowcoder hot-subject API is rate-limiting, temporarily down, or returns a business error (e.g., code 1001, code -1). The API is hit with a cache-busting `_=${Date.now()}` timestamp query parameter.

Common situations: The Nowcoder gateway is under maintenance or behind a WAF that blocks non-browser User-Agents. The endpoint path was renamed or deprecated upstream. Intermittent transient failures during peak traffic on nowcoder.com.
