API 参考文档 ​

概述 ​

耗子面板提供了一套安全的 RESTful 接口，用于与面板系统进行交互。所有 API 请求都需要进行 HMAC-SHA256 签名认证以确保通信的安全性和完整性。

基础信息 ​

  • 基础 URL: http(s)://your-panel-domain/{entry}/api/
  • 内容类型: 所有请求和响应均使用 application/json
  • 字符编码: UTF-8

认证机制 ​

API 使用 HMAC-SHA256 签名算法进行认证。每个请求必须包含以下 HTTP 头：

头部名称描述
Content-Type设置为 application/json
X-Timestamp当前 UNIX 时间戳（秒）
Authorization身份验证信息，格式为 HMAC-SHA256 Credential={id}, Signature={signature}

签名算法 ​

签名过程包含四个主要步骤：

1. 构造规范化请求 ​

规范化请求字符串由以下部分组成，各部分之间使用换行符（\n）分隔：

HTTP方法
规范化路径
规范化查询字符串
请求体的SHA256哈希值

注意：规范化路径应始终使用 /api/ 开头的路径部分，忽略入口前缀。

2. 构造待签名字符串 ​

待签名字符串包含以下部分，各部分使用换行符（\n）分隔：

"HMAC-SHA256"
时间戳
规范化请求的SHA256哈希值

3. 计算签名 ​

使用您的令牌（token）对待签名字符串进行 HMAC-SHA256 计算，然后将结果转换为十六进制字符串。

4. 构造授权头 ​

将计算得到的签名添加到 Authorization 头：

Authorization: HMAC-SHA256 Credential={id}, Signature={signature}

常见响应码 ​

HTTP 状态码描述
200请求成功
401身份验证失败
403权限不足
404资源不存在
422请求参数错误
500服务器内部错误

安全建议 ​

  1. 保护您的 API 令牌：不要在客户端代码中硬编码或公开您的 API 令牌
  2. 定期轮换令牌：定期更改您的 API 令牌以提高安全性
  3. 配置 IP 白名单：在生产环境中使用 IP 白名单限制访问

常见问题解答 ​

签名验证失败 ​

如果遇到签名验证失败，请检查：

  • 确保使用了正确的 API 令牌和 ID
  • 检查客户端与服务器的时间是否准确，时间戳偏差大于 300 秒会导致验证失败
  • 确保请求体在计算签名前后没有被修改
  • 确保 URL 路径处理正确，注意规范化路径时需要移除入口前缀

请求超时 ​

  • 检查网络连接
  • 确认服务器状态
  • 考虑增加客户端的超时设置
