+# OpenInstall API 测试结果
+
+## 测试总结
+
+✅ **成功连接到 OpenInstall API**
+
+- API 基础 URL: `https://data.openinstall.com`
+- 测试的接口端点工作正常
+- HTTP 状态码: 200 
+
+## 当前问题
+
+❌ **ApiKey 配置错误**
+
+API 返回错误: `code=3, error="apiKey错误"`
+
+## 问题分析
+
+当前配置中:
+- `AppKey: alf57p` - 这是应用的标识符(AppKey),用于 SDK 集成
+- 但数据接口需要的是单独的 `apiKey`,这两者不同
+
+## 解决方案
+
+### 步骤 1: 在 OpenInstall 后台配置数据接口
+
+1. 登录 OpenInstall 后台: https://www.openinstall.com
+2. 找到 **【数据接口】-【接口配置】** 菜单
+3. **开启数据接口开关**
+4. 获取 `apiKey` (这是专门用于数据接口的密钥,不同于 AppKey)
+
+### 步骤 2: 更新配置文件
+
+在 `ppanel-server/etc/ppanel.yaml` 中添加 `ApiKey`:
+
+```yaml
+OpenInstall:
+  Enable: true
+  AppKey: "alf57p"      # SDK 集成使用
+  ApiKey: "your_api_key_from_backend"  # 数据接口使用
+```
+
+### 步骤 3: 重新测试
+
+获取到正确的 apiKey 后,运行测试程序:
+
+```bash
+cd cmd/test_openinstall
+go run main.go
+```
+
+## 测试接口说明
+
+测试程序当前测试了以下接口:
+
+### 1. 新增安装数据 (Growth Data)
+- 端点: `/data/event/growth`
+- 功能: 获取指定时间范围内的访问量、点击量、安装量、注册量及留存数据
+- 参数:
+  - `apiKey`: 数据接口密钥
+  - `startDate`: 开始日期 (格式: 2006-01-02)
+  - `endDate`: 结束日期
+  - `statType`: 统计类型 (daily=按天, hourly=按小时, total=合计)
+
+返回数据包括:
+- `visit`: 访问量
+- `click`: 点击量
+- `install`: 安装量
+- `register`: 注册量
+- `survive_d1`: 1日留存
+- `survive_d7`: 7日留存
+- `survive_d30`: 30日留存
+
+### 2. 渠道列表 (Channel List)
+- 端点: `/data/channel/list`
+- 功能: 获取 H5 渠道列表
+- 参数:
+  - `apiKey`: 数据接口密钥
+  - `pageNum`: 页码
+  - `pageSize`: 每页数量
+
+## 更多可用接口
+
+OpenInstall 数据接口还提供以下功能:
+
+- 渠道分组管理 (创建、修改、删除)
+- 渠道管理 (创建、修改、删除、查询)
+- 子渠道管理
+- 存量设备数据
+- 活跃数据统计
+- 效果点数据
+- 设备分布统计
+
+详细文档: https://www.openinstall.com/doc/data.html
+
+## 下一步建议
+
+1. **配置 ApiKey**: 按照上述步骤在 OpenInstall 后台获取并配置 apiKey
+2. **更新配置**: 将 apiKey 添加到 `ppanel.yaml` 配置文件
+3. **更新代码**: 修改 `pkg/openinstall/openinstall.go` 实现真实的 API 调用
+4. **测试验证**: 重新运行测试程序验证数据获取

+# Nginx 下载日志解密工具
+
+## 简介
+
+此工具用于解密 Nginx 访问日志中 `/v1/common/client/download` 接口的加密 `data` 参数。
+
+通讯密钥：`c0qhq99a-nq8h-ropg-wrlc-ezj4dlkxqpzx`
+
+## 解密结果示例
+
+从 Nginx 日志解密后，可以获得下载请求的详细信息，例如：
+
+```json
+{"platform":"windows"}
+{"platform":"mac"}
+{"platform":"android"}
+{"platform":"ios"}
+```
+
+还可能包含邀请码信息：
+```json
+{"platform":"windows","invite_code":"ABC123"}
+```
+
+## 使用方法
+
+### 方法 1: 使用 Shell 脚本（推荐）
+
+```bash
+# 解密单条日志

+```
+
+### 方法 2: 直接运行 Go 程序
+
+```bash
+go run cmd/decrypt_download_data/main.go
+```
+
+默认会解密内置的示例日志。
+
+### 方法 3: 从 Nginx 日志文件批量解密
+
+```bash
+# 提取所有 download 请求并解密
+grep "/v1/common/client/download" /var/log/nginx/access.log | \
+  while read line; do
+    ./decrypt_download.sh "$line"
+  done
+```
+
+## 从 Nginx 服务器上使用
+
+如果您在 Nginx 服务器上（root@localhost7701），可以这样操作：
+
+1. **查找所有 download 请求**：
+```bash
+grep "/v1/common/client/download" /var/log/nginx/access.log
+```
+
+2. **统计各平台下载量**：
+先解密所有日志，然后统计：
+```bash
+# 需要将此工具复制到服务器，或在本地解密后统计
+```
+
+3. **实时监控**：
+```bash
+tail -f /var/log/nginx/access.log | grep "/v1/common/client/download"
+```
+
+## 技术细节
+
+### 加密方式
+- **算法**：AES-CBC with PKCS7 padding
+- **密钥长度**：256 位（通过 SHA256 哈希生成）
+- **IV 生成**：基于时间戳的 MD5 哈希
+
+### 参数说明
+- `data`: URL 编码的 Base64 加密数据
+- `time`: 用于生成 IV 的时间戳字符串
+
+### 解密流程
+1. URL 解码 `data` 参数
+2. Base64 解码得到密文
+3. 使用通讯密钥和 `time` 生成解密密钥和 IV
+4. 使用 AES-CBC 解密得到原始 JSON 数据
+
+## 相关文件
+
+- `cmd/decrypt_download_data/main.go` - 解密工具主程序
+- `decrypt_download.sh` - Shell 脚本快捷方式
+- `pkg/aes/aes.go` - AES 加密解密库
+
+## 注意事项
+
+⚠️ **安全提示**：通讯密钥应妥善保管，不要泄露给未授权人员。
