CNKI Paper Download (文献下载)

Prerequisites

User must be logged in to CNKI with download permissions.

Arguments

$ARGUMENTS is optionally a paper detail URL. If blank, uses current page.

Steps

1. Navigate (if URL provided)

If URL provided: use navigate_page to go to the URL directly (no wait_for needed — Step 2 handles waiting).

Important: Always use navigate_page instead of clicking links on the search results page. Clicking opens a new tab and wastes 3 extra tool calls (list_pages + select_page + take_snapshot).

2. Check status and download (single async evaluate_script)

Replace FORMAT with "pdf" or "caj":

async () 

3. Report

Based on JS result:

• status: downloading → "PDF 下载已触发：{title}。请在 Chrome 下载管理器中查看。"
• error: not_logged_in → tell user to log in
• error: captcha → tell user to solve captcha

Tool calls: 1–2 (navigate_page if URL + evaluate_script)

Verified selectors

Captcha detection

Check #tcaptcha_transform_dy element's getBoundingClientRect().top >= 0. Only active when top >= 0 (visible). Pre-loaded SDK sits at top: -1000000px.
