 1 | # LanZou_API
 2 | 
 3 | 一个用于解析蓝奏云分享链接的 API 服务，支持获取文件信息和下载链接。
 4 | 
 5 | ## 功能特性
 6 | 
 7 | - 支持解析蓝奏云分享链接
 8 | - 支持带密码的分享链接
 9 | - 支持获取文件详细信息（文件名、大小、上传时间）
10 | - 支持直接获取下载链接
11 | 
12 | ## 安装说明
13 | 
14 | 1. 克隆项目到本地：
15 | ```bash
16 | git clone https://github.com/5ime/Lanzou_API
17 | ```
18 | 
19 | 2. 确保服务器环境满足以下要求：
20 | - PHP 7.0 或更高版本
21 | - 启用 cURL 扩展
22 | - 支持 HTTPS 请求
23 | 
24 | ## 使用方法
25 | 
26 | ### 基本使用
27 | 
28 | 通过 HTTP GET 请求访问 `public/index.php`，支持以下参数：
29 | 
30 | - `url`：蓝奏云分享链接（必填）
31 | - `pwd`：提取码（如果有密码则必填）
32 | - `type`：值为 "down" 时直接跳转下载，否则返回下载链接
33 | 
34 | ### 示例请求
35 | 
36 | 1. 获取文件信息：
37 | ```
38 | GET /LanZou_API/public/index.php?url=https://www.lanzoui.com/xxxxxx
39 | ```
40 | 
41 | 2. 带密码的分享链接：
42 | ```
43 | GET /LanZou_API/public/index.php?url=https://www.lanzoui.com/xxxxxx&pwd=xxxx
44 | ```
45 | 
46 | 3. 直接下载：
47 | ```
48 | GET /LanZou_API/public/index.php?url=https://www.lanzoui.com/xxxxxx&pwd=xxxx&type=down
49 | ```
50 | 
51 | ### 返回格式
52 | 
53 | 成功响应：
54 | ```json
55 | {
56 |   "code": 200,
57 |   "msg": "解析成功",
58 |   "data": {
59 |     "name": "文件名",
60 |     "size": "文件大小",
61 |     "time": "上传时间",
62 |     "url": "下载链接"
63 |   }
64 | }
65 | ```
66 | 
67 | 错误响应：
68 | ```json
69 | {
70 |   "code": 400,
71 |   "msg": "错误信息",
72 |   "data": null
73 | }
74 | ```
75 | 
76 | ## 注意事项
77 | 
78 | 1. 请确保服务器能够正常访问蓝奏云网站
79 | 2. 建议在服务器端设置适当的请求频率限制
80 | 3. 本API仅供学习交流使用，请勿用于商业用途
81 | 4. 使用过程中如遇到问题，请检查：
82 |    - 分享链接是否有效
83 |    - 提取码是否正确
84 |    - 文件是否被删除
85 |    - 服务器网络连接是否正常
