使用方式

  1. 实际操作中请将 https://example.ml 换成你自己的域名！
  2. 接口请求方式一律为 GET

安装

接口参数

  • action - 定值，填 install

示例调用

curl https://example.ml/index.php?action=install

返回内容

{
  "code": 200,
  "msg": "秘钥仅显示一次！请自行保存！",
  "data": "bd17cf2d3f14ae53bcd5c21a24cc5454f0f52d5a9591d2e0275debd8641765e3"
}

更新IP

接口参数

  • action - 定值，填 update
  • token - 填写 安装 中获取到的令牌

示例调用

curl https://example.ml/index.php?action=update&token=bd17cf2d3f14ae53bcd5c21a24cc5454f0f52d5a9591d2e0275debd8641765e3

返回预览

{
  "code": "IP地址信息已更新！",
  "msg": {
    "ip": "60.168.244.239",
    "update_time": 1650553426,
    "format_update_time": "2022年04月21日 23:03:46"
  }
}

获取地址

如需获取地址，则无需传入任何参数，直接访问脚本即可

示例调用

curl https://example.ml/index.php

返回预览

{
  "code": 200,
  "msg": "获取IP信息成功",
  "data": {
    "ip": "60.168.244.239",
    "update_time": 1650553426,
    "format_update_time": "2022年04月21日 23:03:46"
  }
}
