# 使用 Apache 部署

使用 Apache HTTP Server 架設 BentoPDF。

## 事前準備

- Apache 2.4+
- 已啟用 mod_rewrite
- SSL 憑證（建議）

## 步驟 1：建置專案

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

若要自訂品牌，請在建置前設定環境變數：

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

## 步驟 2：複製檔案

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

## 步驟 3：Apache 設定

建立 `/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>
```

## 步驟 4：用於路由的 .htaccess

建立 `/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
```

## 步驟 5：啟用必要模組

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

## 步驟 6：啟用網站

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

## 子目錄部署

若要架設在 `/pdf/`：

1. 以 base URL 建置：

```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
```

## 疑難排解

### WASM 404 錯誤

請確認已設定 MIME 類型：

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

### 簽署 PDF 或表單填寫工具顯示空白檢視器（`.mjs` MIME 錯誤）

如果瀏覽器主控台顯示：

```
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.
```

…且失敗的請求以 `.mjs` 結尾，表示您的 Apache 設定缺少 `.mjs → application/javascript` 對應。內建的 PDF 檢視器以 `.mjs` 副檔名提供 ES module 檔案，而 Apache 內建的 `mime.types` 預設並未包含它。

加入您的 VirtualHost 或 `.htaccess`：

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

然後重新載入 Apache：

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

確認方式：在瀏覽器 DevTools → Network 分頁中，找到失敗的 `.mjs` 請求並檢查 `Content-Type` 回應標頭。現在應為 `application/javascript`，而不是 `application/octet-stream`。

### Rewrite 無法運作

確認已啟用 mod_rewrite：

```bash
sudo a2enmod rewrite
```

### Word/ODT/Excel 轉 PDF 無法運作

LibreOffice WASM 需要 `SharedArrayBuffer`，而它需要以下標頭：

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

它也需要安全環境（secure context）。`http://localhost` 可用於本機測試，但 `http://192.168.x.x` 或其他區域網路 IP 通常需要 HTTPS。如果標頭已存在但 `window.crossOriginIsolated` 仍為 `false`，請檢查頁面是否透過一般 HTTP 在非迴路位址的來源上開啟。

預先壓縮的 `.wasm.gz` 與 `.data.gz` 檔案也需要正確的 `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>
```

請確認已啟用 `mod_headers`：`sudo a2enmod headers`

### 權限遭拒

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