12306 Train Ticket Inquiry Skill

技能概述

Skill Overview

本技能提供标准化的12306火车票查询能力，基于实际验证的操作流程，确保每次查询都能准确获取到火车班次信息。技能封装了完整的查询SOP，包括URL参数直接查询（推荐）和表单交互查询（备选）两种模式。

This skill provides standardized 12306 train ticket inquiry capability, based on verified operation processes to ensure accurate acquisition of train schedule information for each query. The skill encapsulates a complete query SOP, including two modes: Direct URL Parameter Query (Recommended) and Form Interaction Query (Alternative).

使用场景

Usage Scenarios

注意事项

Notes

车站代码系统: 12306内部使用车站代码（如BOP=北京东，BJP=北京），但用户只需输入城市名
历史记录干扰: 表单输入可能受历史记录影响，推荐使用URL参数查询
日期格式: 必须使用"YYYY-MM-DD"格式，如"2026-03-14"
查询限制: 单次查询最多显示15天内的车次信息
余票状态: 准确识别"有"、"无"、"候补"三种状态，部分车次显示具体余票数量

Station Code System: 12306 uses internal station codes (e.g., BOP=Beijing East, BJP=Beijing), but users only need to enter city names
History Record Interference: Form input may be affected by history records, direct URL parameter query is recommended
Date Format: Must use "YYYY-MM-DD" format, e.g., "2026-03-14"
Query Limit: A single query can display train information for up to 15 days in advance
Ticket Availability Status: Accurately identify three states: "Available", "Unavailable", "Waitlist", some trains show specific ticket quantities
