+# kkFileView 安全配置指南
+
+## ⚠️ 重要安全更新
+
+从 4.4.0 之后版本开始，kkFileView 增强了安全性，默认拒绝所有未配置的外部文件预览请求，以防止 SSRF（服务器端请求伪造）攻击。
+
+## 🔒 安全配置说明
+
+### 1. 信任主机白名单配置（推荐）
+
+在 `application.properties` 中配置允许预览的域名：
+
+```properties
+# 方式1：通过配置文件
+trust.host = kkview.cn,yourdomain.com,cdn.example.com
+
+# 方式2：通过环境变量
+KK_TRUST_HOST=kkview.cn,yourdomain.com,cdn.example.com
+```
+
+**示例场景**：
+- 只允许预览来自 `oss.aliyuncs.com` 和 `cdn.example.com` 的文件
+```properties
+trust.host = oss.aliyuncs.com,cdn.example.com
+```
+
+### 2. 允许所有主机（不推荐，仅测试环境）
+
+```properties
+trust.host = *
+```
+
+⚠️ **警告**：此配置会允许访问任意外部地址，存在安全风险，仅应在测试环境使用！
+
+### 3. 黑名单配置（高级）
+
+禁止特定域名或内网地址：
+
+```properties
+# 禁止访问内网地址（强烈推荐）
+not.trust.host = localhost,127.0.0.1,192.168.*,10.*,172.16.*,169.254.*
+
+# 禁止特定恶意域名
+not.trust.host = malicious-site.com,spam-domain.net
+```
+
+**优先级**：黑名单 > 白名单
+
+### 4. Docker 环境配置
+
+```bash
+docker run -d \
+  -e KK_TRUST_HOST=yourdomain.com,cdn.example.com \
+  -e KK_NOT_TRUST_HOST=localhost,127.0.0.1 \
+  -p 8012:8012 \
+  keking/kkfileview:4.4.0
+```
+
+## 🛡️ 安全最佳实践
+
+### ✅ 推荐配置
+
+```properties
+# 1. 明确配置信任主机白名单
+trust.host = your-cdn.com,your-storage.com
+
+# 2. 配置黑名单防止内网访问
+not.trust.host = localhost,127.0.0.1,192.168.*,10.*,172.16.*
+
+# 3. 禁用文件上传（生产环境）
+file.upload.disable = true
+
+# 4. 配置基础URL（使用反向代理时）
+base.url = https://preview.yourdomain.com
+```
+
+### ❌ 不推荐配置
+
+```properties
+# 危险：允许所有主机访问
+trust.host = *
+
+# 危险：启用文件上传（生产环境）
+file.upload.disable = false
+```
+
+## 🔍 配置验证
+
+### 测试白名单是否生效
+
+1. 配置白名单：
+```properties
+trust.host = kkview.cn
+```
+
+2. 尝试预览白名单内的文件：
+```
+http://localhost:8012/onlinePreview?url=https://kkview.cn/test.pdf
+✅ 应该可以正常预览
+```
+
+3. 尝试预览白名单外的文件：
+```
+http://localhost:8012/onlinePreview?url=https://other-domain.com/test.pdf
+❌ 应该被拒绝，显示"不信任的文件源"
+```
+
+### 测试黑名单是否生效
+
+1. 配置黑名单：
+```properties
+not.trust.host = localhost,127.0.0.1
+```
+
+2. 尝试访问本地文件：
+```
+http://localhost:8012/getCorsFile?urlPath=http://127.0.0.1:8080/admin
+❌ 应该被拒绝
+```
+
+## 📋 常见问题
+
+### Q1: 升级后无法预览文件了？
+
+**原因**：新版本默认拒绝未配置的主机。
+
+**解决**：在配置文件中添加信任主机列表：
+```properties
+trust.host = your-file-server.com
+```
+
+### Q2: 如何临时恢复旧版本行为？
+
+**不推荐**，但如果确实需要：
+```properties
+trust.host = *
+```
+
+### Q3: 配置了白名单但还是无法访问？
+
+检查以下几点：
+1. 域名是否完全匹配（区分大小写）
+2. 是否配置了黑名单，黑名单优先级更高
+3. 查看日志中的 WARNING 信息
+4. 确认环境变量是否正确设置
+
+### Q4: 如何允许子域名？
+
+已支持通配符域名匹配，可使用 `*.example.com`：
+```properties
+trust.host = *.example.com
+```
+
+说明：
+- `*.example.com` 会匹配 `cdn.example.com`、`api.internal.example.com`，但不匹配根域 `example.com`
+- 对于 IP 风格通配（如 `192.168.*`、`10.*`），仅匹配字面量 IPv4 地址，不匹配域名
+
+## 🚨 安全事件响应
+
+如果发现可疑的预览请求：
+
+1. 检查日志文件，搜索 "拒绝访问主机" 关键字
+2. 确认 `trust.host` 配置是否合理
+3. 检查是否有异常的网络请求
+4. 如发现攻击行为，及时更新黑名单配置

+# 构建说明
+
+由于 kkfileview 的基础运行环境很少变动且制作耗时较久，而 kkfileview 本身代码开发会频繁改动，因此把制作其 Docker 镜像的步骤拆分为两次：
+
+首先制作 kkfileview 的基础镜像（kkfileview-base）。
+
+然后使用 kkfileview-base 作为基础镜像进行构建，加快 kkfileview docker 镜像构建与发布。
+
+执行如下命令即可构建基础镜像：
+> 这里镜像 tag 以 4.4.0 为例，本项目所维护的 Dockerfile 文件考虑了跨平台兼容性。 如果你需要用到 arm64 架构镜像, 则在arm64 架构机器上同样执行下面的构建命令即可
+
+```shell
+docker build --tag keking/kkfileview-base:4.4.0 .
+```
+
+
+
+## 跨平台构建
+
+`docker buildx` 支持在一台机器上构建出多种平台架构的镜像。推荐使用该能力进行跨平台的镜像构建。
+例如，执行 `docker buildx build` 命令时加上 `--platform=linux/arm64` 参数即可构建出 arm64 架构镜像。这极大方便了那些没有arm64 架构机器却想构建 arm64 架构镜像的用户。
+
+> 当前本项目仅支持构建 linux/amd64 和 linux/arm64 两种平台架构的镜像
+> buildx 的 builder driver 可以使用默认的 `docker` 类型, 若使用 `docker-container` 类型可以支持并行构建多种架构, 本文不再赘述, 有兴趣可以自行了解。参考 [Docker Buildx | Docker Documentation](https://docs.docker.com/buildx/working-with-buildx/#build-multi-platform-images)
+
+**前提要求**
+
+以当前机器为 amd64 (x86_64)架构为例。需要开启 docker 的 buildx 特性，以及开启 Linux 的 QEMU 用户模式：
+
+> 使用 WSL2 的 Windows 用户如果安装了最新的 DockerDesktop, 则这些前提要求已满足, 无需额外下述设置。 
+
+1. 安装 docker buildx 客户端插件：
+   > docker 版本要求 >=19.03
+   
+   若已安装, 则跳过。详情参考 https://github.com/docker/buildx
+
+2. 开启 QEMU 的用户模式功能, 并安装其它平台的模拟器:
+   > Linux 内核要求 >=4.8
+
+   使用 `tonistiigi/binfmt` 镜像可快速开启并安装模拟器，执行下面命令:
+
+   ```shell
+   docker run --privileged --rm tonistiigi/binfmt --install all
+   ```
+
+现在就可以愉快地开始构建了，构建命令示例:
+
+```shell
+docker buildx build --platform=linux/amd64,linux/arm64 -t keking/kkfileview-base:4.4.0 --push .
+```

+# Build Instructions
+
+Since the base runtime environment for kkfileview rarely changes and takes a long time to build, while the kkfileview code itself is frequently updated, the process of building its Docker image is split into two steps:
+
+First, create the base image for kkfileview (kkfileview-base).
+
+Then, use kkfileview-base as the base image to build and speed up the kkfileview Docker image build and release process.
+
+To build the base image, run the following command:
+
+> In this example, the image tag is 4.4.0. The Dockerfile maintained in this project considers cross-platform compatibility. If you need an arm64 architecture image, run the same build command on an arm64 architecture machine.
+
+```shell
+docker build --tag keking/kkfileview-base:4.4.0 .
+```
+
+
+
+## Cross-Platform Build
+
+`docker buildx` supports building images for multiple platform architectures on a single machine. It is recommended to use this capability for cross-platform image builds.
+For example, adding the `--platform=linux/arm64` parameter when executing the `docker buildx build` command will allow you to build an arm64 architecture image. This is particularly convenient for users who want to build arm64 images but don't have an arm64 machine.
+
+> Currently, this project only supports building images for the linux/amd64 and linux/arm64 architectures.
+> The buildx builder driver can use the default `docker` type, but if you use the `docker-container` type, you can build multiple architectures in parallel. This README will not cover that in detail, you can learn more on your own. Refer to [Docker Buildx | Docker Documentation](https://docs.docker.com/buildx/working-with-buildx/#build-multi-platform-images)
+
+**Prerequisites**
+
+Assuming the current machine is amd64 (x86_64) architecture, you'll need to enable the docker buildx feature and enable Linux QEMU user mode:
+
+> Windows users with WSL2 who have installed a recent version of Docker Desktop will already meet these prerequisites, so no additional setup is required.
+
+1. Install the docker buildx client plugin:
+
+   > Docker version >=19.03 is required.
+
+   If it's already installed, you can skip this step. For more details, refer to https://github.com/docker/buildx.
+
+2. Enable QEMU user mode and install emulators for other platforms:
+
+   > Linux kernel version >=4.8 is required.
+
+   You can quickly enable and install emulators using the tonistiigi/binfmt image by running the following command:
+
+   ```shell
+   docker run --privileged --rm tonistiigi/binfmt --install all
+   ```
+
+Now you can enjoy the building. Here’s an example build command:
+
+```shell
+docker buildx build --platform=linux/amd64,linux/arm64 -t keking/kkfileview-base:4.4.0 --push .
+```
