Ctrip Hotel Price Skill

Storage State

This skill requires a pre-authenticated browser state at ~/.swat/playwright/ctrip-storage-state.json. If missing or expired, fail the operation — debrief will notify the user to re-authenticate.

CLI Scripts

All scripts require NODE_PATH=$(npm root -g) to resolve playwright.

Auth Check

NODE_PATH=$(npm root -g) node scripts/auth.js --check

Always exits 0. Outputs one of:

• OK — storage state exists and login is valid
• EXPIRED — storage state exists but login has expired
• MISSING — no storage state file found

Parse stdout to determine status. If expired or missing, fail the operation — debrief will notify the user to re-authenticate.

Login

NODE_PATH=$(npm root -g) node scripts/auth.js --login --timeout 300

1. Opens Ctrip login page, screenshots QR code
2. Outputs QR_SCREENSHOT=<path> — send this image to the user to scan with Ctrip app
3. Waits for user to scan (up to --timeout seconds)
4. On success: outputs LOGIN_SUCCESS + STATE_SAVED=<path>
5. On timeout: outputs LOGIN_TIMEOUT

Search Hotel Price

NODE_PATH=$(npm root -g) node scripts/search.js \
  --hotel "维也纳国际酒店苏州新区高铁站" \
  --city 苏州 \
  --checkin 2026-04-18 \
  --checkout 2026-04-19

Arguments:

• --hotel (required) — full hotel name as shown on Ctrip (must match search suggestion exactly)
• --city (required) — Chinese city name (see supported cities below)
• --checkin (optional) — check-in date, YYYY-MM-DD format (defaults to today; during 00:00-05:00 CST defaults to yesterday per Ctrip's 凌晨 convention)
• --checkout (optional) — check-out date, YYYY-MM-DD format (defaults to checkin + 1 day)

Flow: Opens m.ctrip.com mobile search → types hotel name → clicks matching suggestion → lands on list page → adjusts URL date params (c-in/c-out) → extracts price + hotel ID from list page → navigates to hotel detail page → extracts promotions + room types.

Output: JSON object:

{
  "status": "success",
  "query": { "hotel": "...", "city": "...", "checkin": "...", "checkout": "..." },
  "date": "2026-04-18",
  "hotel": {
    "name": "维也纳国际酒店(苏州新区高铁站店)",
    "rating": 4.6,
    "price": 299,
    "originalPrice": 458,
    "promotions": [
      "优惠券 | 94 | 折 | 无金额门槛 | 限额50元 | 春日酒店特惠券"
    ],
    "rooms": [
      {
         
         
         
         
         
         
         
         
      
    
  

New in v1.2.0: After finding the hotel on the list page, the script navigates to the hotel detail page to extract:

• promotions — booking coupons from the "订房优惠" popup. Each coupon is a pipe-separated string of its raw fields. null if no promotions available.
• rooms — all available room types with name, bed type, area, price, original price, discount summary, tags (e.g. "十亿豪补", "新客体验钻石"), and sold-out status. null if extraction fails.

Status values: success, not_found, sold_out, error. On error, the message field contains details. The script always outputs valid JSON, even on unexpected failures.

Sold-out output (status: "sold_out"):

When the matched hotel is sold out for the requested dates, the script extracts a reference price from the page's "这些日期还可订" suggestion if available.

{
  "status": "sold_out",
  "query": { "hotel": "...", "city": "...", "checkin": "...", "checkout": "..." },
  "date": "2026-04-18",
  "hotel": {
    "name": "matched hotel name",
    "rating": 4.6,
    "price": null,
    "originalPrice": null,
    "soldOut": true,
    "referencePrice": { "dates":    
  

The referencePrice field is null if no alternative dates are suggested.

Supported cities: 北京, 上海, 广州, 深圳, 杭州, 苏州, 南京, 成都, 武汉, 西安, 重庆, 长沙, 厦门, 青岛, 大连, 天津, 三亚, 珠海, 昆明, 郑州, 合肥, 哈尔滨, 丽江, 桂林, 拉萨, 沈阳, 济南, 福州, 无锡, 宁波, 常州, 温州, 东莞

To add a new city: open m.ctrip.com, search the city, check the list page URL d-city=NNN for its ID, and add it to CITY_MAP in search.js.

Anti-Detection

The scripts include:

• Random delays (1500–3500ms) between actions
• Realistic user agent and mobile viewport (375×812)
• Chinese locale (zh-CN)

Hotel Matching

The search script types the full hotel name into the search box and clicks the matching suggestion from Ctrip's autocomplete. The hotel name must match exactly as shown on Ctrip. On the results list page, the script uses substring matching (first 6 chars) to locate the hotel card and extract pricing.

Notes

• Detail page adds ~10-15s per hotel query (navigation + rendering + promotion popup)
• Ctrip uses Private Use Area Unicode characters (U+E000–U+F8FF) for icon fonts — the script strips these during text extraction
• Storage state expires after days/weeks — fail and debrief if auth errors occur
• Add delays between requests to avoid rate limiting
• All content is Chinese — requires fonts-noto-cjk on the system
• Price extraction looks for ¥NNN patterns: first match = current price, second = original/strikethrough price
• During 凌晨 (00:00-05:00 CST), Ctrip treats the previous calendar day as check-in date — the script handles this automatically
