 1 | ## 因调用量过大导致服务器IP被屏蔽，今后不再提供示例站点，请自行搭建相关服务
 2 | # LanzouAPI
 3 | <a href="https://github.com/hanximeng/LanzouAPI/archive/refs/heads/master.zip">下载源码</a>
 4 | ## 说明
 5 | 1. 支持检测文件是否被取消
 6 | 
 7 | 2. 支持带密码的文件分享链接但不支持分享的文件夹
 8 | 
 9 | 3. 支持生成直链或直接下载
10 | 
11 | 4. 增加ios应用在线安装
12 | 
13 | 5. 解析最终直链
14 | 
15 | 6. 自动识别旧版链接替换为新版并解析
16 | 
17 | ## 使用方法
18 | 
19 | url:蓝奏云外链链接
20 | 
21 | type:是否直接下载 值：down
22 | 
23 | pwd:外链密码
24 | 
25 | ### 直接下载：
26 | 
27 | 无密码：?url=https://www.lanzouq.com/iGNHA6th9cd&type=down
28 | 
29 | 有密码：?url=https://www.lanzous.com/i42Xxebssfg&type=down&pwd=1234
30 | 
31 | 
32 | ### 输出直链：
33 | 
34 | 无密码：?url=https://www.lanzouq.com/iGNHA6th9cd
35 | 
36 | 有密码：?url=https://www.lanzous.com/i42Xxebssfg&pwd=1234
