Error message

got the page failed: %s

What it means

During lrts chapter enumeration the extractor POSTs to http://www.lrts.me/ajax/book/<book>/<page>/<pageSize> and expects JSON with status 'success'. Any other status (failure, auth, rate-limit) triggers AssertionError("got the page failed: %s") with the failing page URL — the chapter list for that page cannot be trusted, so the run aborts.

Solutions

1. Retry after a short delay — transient rate-limit responses commonly clear
2. Check the raw POST response (curl -X POST the page_url) to see the actual status/message returned
3. Ensure --first/--last/--page_size values stay within the book's page count derived from totalCount
4. If the endpoint moved or requires headers, update post_content call (URL/headers) in src/you_get/extractors/lrts.py:47

Example fix

# before
response_content = json.loads(post_content(page_url, headers))
if response_content['status'] != 'success':
    raise AssertionError("got the page failed: %s" % (page_url))

# after (break instead of aborting when an out-of-range page comes back empty/failed)
response_content = json.loads(post_content(page_url, headers))
if response_content['status'] != 'success':
    if page > 0:
        break  # past the last page
    raise AssertionError("got the page failed: %s" % (page_url))

import json

def lrts_page_ok(post_fn, page_url, headers):
    return json.loads(post_fn(page_url, headers)).get('status') == 'success'

for attempt in range(3):
    try:
        lrts_download(url, ...)
        break
    except AssertionError as e:
        if 'got the page failed' in str(e) and attempt < 2:
            time.sleep(2 ** attempt)
            continue
        raise

When it happens

Trigger: Requesting a page index beyond the book's real range (custom --last too large), the server rate-limiting burst POSTs, session/cookie requirements, or the AJAX endpoint schema changing so status is no longer the literal 'success'.

Common situations: User-supplied page_size mismatching the site's expected 10 causing out-of-range pages; hammering pagination in a loop; site adding CSRF/auth to ajax routes.
