# 使用 Apache 部署

使用 Apache HTTP Server 托管 BentoPDF。

## 前置条件

- Apache 2.4+
- 已启用 mod_rewrite
- SSL 证书（推荐）

## 第 1 步：构建项目

```bash
git clone https://github.com/alam00000/bentopdf.git
cd bentopdf
npm install
npm run build
```

如需自定义品牌，请在构建前设置环境变量：

```bash
VITE_BRAND_NAME="AcmePDF" VITE_BRAND_LOGO="images/acme-logo.svg" npm run build
```

## 第 2 步：复制文件

```bash
sudo mkdir -p /var/www/bentopdf
sudo cp -r dist/* /var/www/bentopdf/
sudo chown -R www-data:www-data /var/www/bentopdf
```

## 第 3 步：Apache 配置

创建 `/etc/apache2/sites-available/bentopdf.conf`：

```apache
<VirtualHost *:80>
    ServerName your-domain.com
    Redirect permanent / https://your-domain.com/
</VirtualHost>

<VirtualHost *:443>
    ServerName your-domain.com
    DocumentRoot /var/www/bentopdf

    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/your-domain.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/your-domain.com/privkey.pem

    <Directory /var/www/bentopdf>
        Options -Indexes +FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    # WASM MIME type
    AddType application/wasm .wasm

    # Prevent double-compression of pre-compressed files
    SetEnvIfNoCase Request_URI "\.gz$" no-gzip

    # Compression
    <IfModule mod_deflate.c>
        AddOutputFilterByType DEFLATE text/html text/plain text/css application/javascript application/json application/wasm
    </IfModule>

    # Cache headers
    <IfModule mod_expires.c>
        ExpiresActive On
        ExpiresByType application/javascript "access plus 1 year"
        ExpiresByType text/css "access plus 1 year"
        ExpiresByType application/wasm "access plus 1 year"
        ExpiresByType image/png "access plus 1 year"
        ExpiresByType image/svg+xml "access plus 1 year"
    </IfModule>

    # Required headers for SharedArrayBuffer (LibreOffice WASM)
    Header always set Cross-Origin-Embedder-Policy "require-corp"
    Header always set Cross-Origin-Opener-Policy "same-origin"
    Header always set Cross-Origin-Resource-Policy "cross-origin"

    # Security headers
    Header always set X-Frame-Options "SAMEORIGIN"
    Header always set X-Content-Type-Options "nosniff"

    # Pre-compressed LibreOffice WASM files
    <FilesMatch "soffice\.wasm\.gz$">
        ForceType application/wasm
        Header set Content-Encoding "gzip"
    </FilesMatch>
    <FilesMatch "soffice\.data\.gz$">
        ForceType application/octet-stream
        Header set Content-Encoding "gzip"
    </FilesMatch>
</VirtualHost>
```

## 第 4 步：用于路由的 .htaccess

创建 `/var/www/bentopdf/.htaccess`：

```apache
RewriteEngine On
RewriteBase /

# Existing files/dirs - serve directly
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]

# ============================================
# LANGUAGE ROUTES
# ============================================
# Supported languages: de, es, zh, zh-TW, vi, it, id, tr, fr, pt
# English has no prefix - served from root

# English prefix redirects to root
RewriteRule ^en/?$ / [R=301,L]
RewriteRule ^en/(.+)$ /$1 [R=301,L]

# Language prefix root (e.g., /de/ -> /de/index.html)
RewriteCond %{DOCUMENT_ROOT}/$1/index.html -f
RewriteRule ^(de|es|zh|zh-TW|vi|it|id|tr|fr|pt)/?$ /$1/index.html [L]

# Language prefix with path (e.g., /de/merge-pdf -> /de/merge-pdf.html)
RewriteCond %{DOCUMENT_ROOT}/$1/$2.html -f
RewriteRule ^(de|es|zh|zh-TW|vi|it|id|tr|fr|pt)/([^/]+)/?$ /$1/$2.html [L]

# ============================================
# ADD .HTML EXTENSION (ROOT LEVEL)
# ============================================
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^([^/]+)$ $1.html [L]

ErrorDocument 404 /404.html
```

## 第 5 步：启用所需模块

```bash
sudo a2enmod rewrite
sudo a2enmod ssl
sudo a2enmod headers
sudo a2enmod expires
sudo a2enmod deflate
```

## 第 6 步：启用站点

```bash
sudo a2ensite bentopdf.conf
sudo apache2ctl configtest
sudo systemctl reload apache2
```

## 子目录部署

要部署在 `/pdf/` 下：

1. 使用基础 URL 构建：

```bash
BASE_URL=/pdf/ npm run build
```

2. 更新 `.htaccess`：

```apache
RewriteEngine On
RewriteBase /pdf/

# Existing files/dirs - serve directly
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]

# Language routes
RewriteRule ^en/?$ /pdf/ [R=301,L]
RewriteRule ^en/(.+)$ /pdf/$1 [R=301,L]

RewriteCond %{DOCUMENT_ROOT}/pdf/$1/index.html -f
RewriteRule ^(de|es|zh|zh-TW|vi|it|id|tr|fr|pt)/?$ /pdf/$1/index.html [L]

RewriteCond %{DOCUMENT_ROOT}/pdf/$1/$2.html -f
RewriteRule ^(de|es|zh|zh-TW|vi|it|id|tr|fr|pt)/([^/]+)/?$ /pdf/$1/$2.html [L]

# Root level .html extension
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^([^/]+)$ $1.html [L]

ErrorDocument 404 /pdf/404.html
```

## 故障排查

### WASM 404 错误

请确认已配置 MIME 类型：

```apache
AddType application/wasm .wasm
```

### 签名 PDF 或表单填写器显示空白查看器（`.mjs` MIME 错误）

如果浏览器控制台显示：

```
Failed to load module script: The server responded with a non-JavaScript
MIME type of "application/octet-stream". Strict MIME type checking is
enforced for module scripts per HTML spec.
```

……并且失败的请求以 `.mjs` 结尾，说明您的 Apache 配置缺少 `.mjs → application/javascript` 的映射。内置的 PDF 查看器使用扩展名为 `.mjs` 的 ES 模块文件，而 Apache 自带的 `mime.types` 默认不包含它们。

将以下内容添加到您的 VirtualHost 或 `.htaccess`：

```apache
AddType application/javascript .mjs
```

然后重新加载 Apache：

```bash
sudo apache2ctl configtest && sudo systemctl reload apache2
```

验证方法：在浏览器 DevTools 的 Network 标签页中找到失败的 `.mjs` 请求，检查 `Content-Type` 响应头。现在它应为 `application/javascript`，而不是 `application/octet-stream`。

### Rewrite 不生效

请检查 mod_rewrite 是否已启用：

```bash
sudo a2enmod rewrite
```

### Word/ODT/Excel 转 PDF 无法使用

LibreOffice WASM 需要 `SharedArrayBuffer`，这需要以下响应头：

```apache
Header always set Cross-Origin-Embedder-Policy "require-corp"
Header always set Cross-Origin-Opener-Policy "same-origin"
```

它还需要安全上下文。`http://localhost` 可用于本地测试，但 `http://192.168.x.x` 等局域网 IP 通常需要 HTTPS。如果响应头已存在，但 `window.crossOriginIsolated` 仍为 `false`，请检查页面是否在非环回来源上通过普通 HTTP 打开。

预压缩的 `.wasm.gz` 和 `.data.gz` 文件还需要正确的 `Content-Encoding`：

```apache
<FilesMatch "soffice\.wasm\.gz$">
    ForceType application/wasm
    Header set Content-Encoding "gzip"
</FilesMatch>
<FilesMatch "soffice\.data\.gz$">
    ForceType application/octet-stream
    Header set Content-Encoding "gzip"
</FilesMatch>
```

请确保已启用 `mod_headers`：`sudo a2enmod headers`

### 权限被拒绝

```bash
sudo chown -R www-data:www-data /var/www/bentopdf
sudo chmod -R 755 /var/www/bentopdf
```
