中国出发特价机票监控的完整方案——从 OTA 逆向到廉价航司直连

Tech-Experiment
🇨🇳 中文

上一篇文章介绍了 Amadeus GDS API 可以拿到全球真实机票价格，但有读者马上指出了盲区：中国出发的航班怎么办？

这个问题问得很准。中国大陆的 GDS——中航信（TravelSky）——是国家控制的基础设施，普通开发者拿不到授权。Amadeus 的接口里，国内航班数据极度有限，且往往是空的。

但这不意味着没有解。

一、实际上有几种数据来源

情况一：国内航班（如北京→三亚、上海→昆明）

中航信封闭，但中国 OTA 平台（携程、去哪儿、飞猪、同程）本身就是中航信的分销渠道，它们的移动端 H5 接口是可以逆向的。技术上，这相当于通过 OTA 的 App/网页接口间接获取 GDS 数据——绕过了你没有授权直连 TravelSky 的问题。

限制：数据属于各 OTA，用于个人出行参考属于灰色地带，商业用途有法律风险。

情况二：中国出发国际航班（如上海→曼谷、广州→新加坡）

主要国际航司（国航、东航、南航、泰航、新航等）的国际航班走国际 GDS，Amadeus 可以查到。但东南亚的廉价航司（亚航、越捷、宿务太平洋、狮航等）大部分不在 Amadeus 里，需要另外的方案。

情况三：东南亚区域内航班（如曼谷→吉隆坡）

廉价航司主场，Amadeus 覆盖有限，Kiwi Tequila API 是目前覆盖最好的第三方数据源。

二、最实用的开源工具：JiPiao

github.com/yangka1212/JiPiao（2026年7月仍在更新）

这是目前 GitHub 上最完整的中文机票价格监控项目，同时支持：

平台实现方式说明
携程 CtripPlaywright 浏览器自动化拦截 flightListSearchForH5 XHR
去哪儿 QunarPlaywright同上
同程 TongchengPlaywright同上
飞猪 Fliggy（阿里旅行）纯 httpx 逆向阿里 MTOP 网关 + MD5 签名，无需浏览器
途牛 Tuniu纯 httpx 逆向接口较简单

飞猪的逆向方案特别有价值：阿里旅行走 h5api.m.taobao.com/h5/mtop.trip.flight.flightSearch/1.0/ 网关，签名算法是 MD5(cookie中的_m_h5_tk首段 + "&" + timestamp + "&" + appKey + "&" + data)，不需要启动浏览器，响应速度快，反爬压力小。

核心功能

# config.yaml 示例
routes:
  - from: SHA           # 上海
    to: BKK             # 曼谷
    dates:
      - "2026-08-15"
      - "2026-08-22"
    alert_threshold: 1200   # 低于 1200 元触发提醒

platforms: [ctrip, fliggy, qunar, tongcheng]

schedule:
  interval_minutes: 90      # 监控间隔
  jitter_minutes: 30        # 随机扰动（规避机器人特征）

notifier:
  serverchan:
    enabled: true
    send_key: "SCTxxx"      # Server酱推送到微信
  • 多平台自动找最低价
  • 低价阈值 + 涨价提醒（两个方向都有推送）
  • SQLite 历史记录，可画价格走势
  • 内置去抖逻辑，价格小波动不重复推送

安装

git clone https://github.com/yangka1212/JiPiao
cd JiPiao
pip install -r requirements.txt
python -m playwright install chromium   # 携程/去哪儿/同程 需要
cp config.example.yaml config.yaml     # 按需修改
python main.py

三、关键坑：必须用中国 IP

这一点经常被忽略。携程、去哪儿等 OTA 对海外 IP 返回不同（往往更高）的价格，或者直接封掉请求。原因：国内外定价策略不同，且反爬系统会过滤非常见地区的请求。

如果你把监控服务部署到海外云（AWS Singapore、HK 等），你监控到的价格可能不是中国用户实际看到的价格。

解决方案：

  • 把监控服务跑在国内云服务器（阿里云 / 腾讯云 / 华为云，选华东或华南节点）
  • 或者用家里的电脑/NAS（24小时开机，中国宽带 IP）

四、国际航线叠加 Amadeus

对于大型航司的国际航班（国航、东航、南航、国际段），Amadeus 免费 API 是最省事的方案：

# 例：上海 → 曼谷，搜索便宜日期
import requests

token = get_amadeus_token(client_id, client_secret)
resp = requests.get(
    "https://test.api.amadeus.com/v1/shopping/flight-dates",
    params={
        "origin": "SHA",        # 上海（所有上海机场）
        "destination": "BKK",   # 曼谷
        "oneWay": True,
        "duration": "1-7",
    },
    headers={"Authorization": f"Bearer {token}"}
)
# 返回最低价日期列表

Amadeus 的 Flight Cheapest Date Search 可以一次拿到未来一段时间内的最低价日期，非常适合监控”什么时候最便宜”而不是”明天多少钱”。

五、东南亚廉价航司：Kiwi Tequila API

AirAsia、VietJet、宿务太平洋、狮子航空这些廉价航司大多不在 Amadeus 里。Kiwi.com（捷克聚合平台）专门做廉价航司覆盖，他们的开发者接口叫 Tequila：

注册：tequila.kiwi.com

import requests

resp = requests.get(
    "https://api.tequila.kiwi.com/v2/search",
    params={
        "fly_from": "SHA",          # 上海
        "fly_to": "BKK",            # 曼谷
        "date_from": "15/08/2026",
        "date_to": "30/08/2026",
        "adults": 1,
        "curr": "CNY",
        "limit": 20,
        "sort": "price",
        "asc_or_desc": "asc",
    },
    headers={"apikey": "YOUR_TEQUILA_KEY"}
)
# 返回按价格排序的航班列表，包含亚航、越捷等廉价航司

Tequila 的免费层每月有调用次数限制，够个人项目用。优点是你不需要处理每个廉价航司的不同接口，Kiwi 统一聚合了。

六、特价票的特殊情况：Flash Sale

“特价机票”分两种：

1. 低价座位（可持续监控） 航司每个航班都有多个座位等级（Y、Q、K、X……），最低价舱位卖完才显示下一档价格。这种可以通过上述方案定时监控，价格一旦出现就提醒。

2. Flash Sale（闪购/促销价） 航司定期推出限时大促，有些价格只在官方 App/小程序里出现几小时。这种很难系统性监控，因为：

  • 不在 OTA 正常搜索结果里
  • 要有该航司账号且已开启推送
  • 有些还要登录状态才能看到

现实的做法：

  • 订阅各航司官方微信公众号（国航、东航、南航、春秋、亚航中国区）
  • 关注飞猪/携程的”特价”频道（有专门的特价 feed）
  • 某些聚合信息源：穷游网特价机票频道、航班管家的降价提醒

七、完整监控架构

针对”中国出发，关注东南亚特价”的场景：

定时任务（每 2 小时，随机扰动）
    ↓
┌─────────────────────────────────────────────┐
│           数据采集层（国内 IP！）             │
├─────────────┬───────────────┬───────────────┤
│  JiPiao     │  Amadeus API  │  Kiwi Tequila │
│ 携程/去哪   │  主要国际航司  │  廉价航司     │
│ 飞猪/同程   │  GDS 价格     │  亚航/越捷等  │
└─────────────┴───────────────┴───────────────┘
    ↓
价格去重 & 合并（同一航班多来源取最低）
    ↓
SQLite 历史数据库
    ↓
低价检测（vs 7日均价，vs 设定阈值）
    ↓
推送告警
  ├── Server酱 → 微信
  ├── Bark → iPhone
  └── Telegram Bot

八、各方案对比

方案适用场景数据质量合规性部署复杂度
JiPiao OTA 逆向国内航班，国际仓★★★★⚠️ 灰色中等
Amadeus 免费 API国际主流航司★★★★★✅ 合规低
Kiwi Tequila国际廉价航司★★★★✅ 合规低
直接刷各航司官网特定航司★★★★★⚠️ 灰色高
订阅官方推送Flash Sale★★★★★✅ 合规零

九、最小可用系统（直接能跑）

如果你只想快速开始，最小的组合是：

  1. JiPiao 监控国内 + 国际仓（关注东南亚主要航线）
  2. Amadeus 补充查国际大航司的便宜日期
  3. Server酱 推送到微信
  4. 部署在国内家用机器或低配国内云服务器（2核2G 够用）

不需要复杂基础设施，SQLite 就能存历史，Python + Playwright 足够跑，每月云服务器成本在 30-50 元人民币。

对于国际廉价航司，用 Kiwi Tequila 补上，加几十行 Python 就能叠加到 JiPiao 的告警管道里。

Complete Flight Price Monitoring for China-Departing Travelers: From OTA Reverse Engineering to LCC Direct Access

The previous article covered Amadeus GDS API for global real airfare data — but readers immediately flagged the blind spot: What about flights departing China?

This is the right question. China’s domestic GDS — TravelSky (中航信) — is government-controlled infrastructure, inaccessible to ordinary developers. Amadeus returns near-empty data for China domestic routes.

But this doesn’t mean there’s no solution.

The Three Data Scenarios

Domestic China flights (e.g., Beijing → Sanya) TravelSky is closed, but Chinese OTAs (Ctrip, Qunar, Fliggy, Tongcheng) are all TravelSky distribution channels. Their mobile H5 APIs can be reverse-engineered — effectively getting GDS data via the OTA layer rather than directly. Gray area legally; fine for personal use.

China-originating international flights (e.g., Shanghai → Bangkok) Major international carriers (Air China, China Eastern, Thai Airways, Singapore Airlines) appear on international GDS. Amadeus free API covers these. But Southeast Asia’s budget carriers (AirAsia, VietJet, Cebu Pacific, Lion Air) are mostly absent from Amadeus — a separate solution is needed.

Southeast Asia regional flights (e.g., Bangkok → Kuala Lumpur) Budget carrier territory. Kiwi’s Tequila API has the best third-party coverage here.

The Key Open Source Tool: JiPiao

github.com/yangka1212/JiPiao (still updated as of July 2026)

The most comprehensive Chinese flight monitoring project on GitHub. Covers five platforms simultaneously:

PlatformImplementationNotes
Ctrip 携程Playwright browser automationIntercepts flightListSearchForH5 XHR
Qunar 去哪儿PlaywrightSame approach
Tongcheng 同程PlaywrightSame approach
Fliggy 飞猪 (Alibaba Travel)Pure httpx reverseAlibaba MTOP gateway + MD5 sign — no browser needed
Tuniu 途牛Pure httpxSimpler API

Fliggy’s reverse engineering is particularly valuable: Alibaba routes through h5api.m.taobao.com/h5/mtop.trip.flight.flightSearch/1.0/ with MD5(token + "&" + timestamp + "&" + appKey + "&" + data) signing. No Playwright needed, faster, less anti-bot pressure.

# config.yaml
routes:
  - from: SHA
    to: BKK
    dates:
      - "2026-08-15"
      - "2026-08-22"
    alert_threshold: 1200  # alert if price drops below 1200 CNY

platforms: [ctrip, fliggy, qunar, tongcheng]

notifier:
  serverchan:
    enabled: true
    send_key: "SCTxxx"  # pushes WeChat notifications via Server酱

Critical Trap: You Need a China IP

This is consistently overlooked. Chinese OTAs return different (usually higher) prices to overseas IPs, or block the requests outright. Domestic vs. international pricing differs; anti-bot systems filter unusual geographic sources.

If you deploy to a non-China server (AWS Singapore, Alibaba HK), you may monitor prices that Chinese users never actually see.

Fix: run on a mainland China cloud server (Aliyun / Tencent Cloud, East China or South China regions), or a home machine on Chinese residential broadband.

Layer 2: Amadeus for Major International Carriers

For Air China, China Eastern, China Southern international routes — and all major global carriers — Amadeus free API is the cleanest option:

# Find cheapest date to fly SHA → BKK
resp = requests.get(
    "https://test.api.amadeus.com/v1/shopping/flight-dates",
    params={"origin": "SHA", "destination": "BKK", "oneWay": True},
    headers={"Authorization": f"Bearer {token}"}
)

Flight Cheapest Date Search returns the lowest-price day across a date range in one call — ideal for “when is the cheapest time to fly” rather than checking a single date repeatedly.

Layer 3: Kiwi Tequila for Budget Carriers

AirAsia, VietJet, Cebu Pacific, Lion Air are mostly absent from Amadeus. Kiwi.com specializes in aggregating budget carriers; their developer API is called Tequila (tequila.kiwi.com):

resp = requests.get(
    "https://api.tequila.kiwi.com/v2/search",
    params={
        "fly_from": "SHA", "fly_to": "BKK",
        "date_from": "15/08/2026", "date_to": "30/08/2026",
        "curr": "CNY", "sort": "price", "asc_or_desc": "asc",
        "limit": 20,
    },
    headers={"apikey": "YOUR_KEY"}
)
# Returns flights including AirAsia, VietJet, sorted by price

Tequila’s free tier fits personal projects. You don’t need to handle each LCC’s separate API — Kiwi aggregates them.

The Flash Sale Problem

“Cheap tickets” in Chinese travel context means two different things:

1. Low fare buckets (systematically monitorable): Every flight has multiple booking classes; the cheapest seats show up in normal OTA search until sold out. JiPiao + Amadeus + Kiwi covers this.

2. Flash Sales (promotional prices): Airlines run periodic limited-time promotions that appear only in official apps for a few hours. Hard to monitor because: they’re outside normal OTA search results, require logged-in airline accounts, and sometimes only visible with push notifications enabled.

Practical approach for flash sales:

  • Follow official WeChat accounts: 国航、东航、南航、春秋、AirAsia China
  • Subscribe to Fliggy/Ctrip “special price” channels (they have dedicated flash sale feeds)
  • 穷游 (Qyer) special ticket channel, 飞常准 (VariFlight) price drop alerts

Minimum Viable Setup

If you just want to start quickly — the smallest practical combination:

  1. JiPiao watching 3-5 routes across Ctrip + Fliggy (covers domestic + international on Chinese OTAs)
  2. Amadeus to check cheapest dates on major international carriers
  3. Kiwi Tequila to fill in LCC pricing
  4. Server酱 for WeChat alerts
  5. Cheap mainland China VPS (2 core / 2GB RAM, ~30-50 CNY/month)

A hundred lines of Python to glue the data into a single SQLite database, one cron job, and you have a functional multi-source price monitor that covers what Chinese travelers actually need.
