# JWT Authentication Fix for OnlyOffice Docs 7.1+
## Problem
The error you encountered:
```
[ERROR] nodeJS - auth missing required parameter document.key (since 7.1 version)
```
And the Chinese error dialog: "错误 - 文档安全令牌的格式不正确" (Document security token format is incorrect)
## Root Cause
Starting with OnlyOffice Docs version 7.1, when JWT authentication is enabled on the server, the entire configuration object must be signed with a JWT token. Simply passing a pre-generated JWT token as a separate field is not sufficient.
According to the [ONLYOFFICE signature documentation](https://api.onlyoffice.com/docs/docs-api/additional-api/signature/), the token must:
1. Be generated using the JWT secret key configured on the server
2. Include the entire configuration object (including `document.key` and all other parameters)
3. Use the HS256 algorithm
## Changes Made
### 1. Added JWT Package
**File: `pubspec.yaml`**
Added `dart_jsonwebtoken: ^2.14.1` to properly sign JWT tokens.
```yaml
dependencies:
flutter:
sdk: flutter
crypto: ^3.0.7
webview_flutter: ^4.13.0
webview_flutter_android: ^4.10.10
webview_flutter_wkwebview: ^3.0.0
dart_jsonwebtoken: ^2.14.1 # NEW
```
### 2. Updated OnlyOfficeViewer Widget
**File: `lib/onlyoffice_viewer.dart`**
**Changed parameter name:**
- ❌ Old: `final String? token;`
- ✅ New: `final String? jwtSecret;`
**Updated JWT signing logic:**
```dart
// Sign the entire config with JWT if secret is provided
if (widget.jwtSecret != null && widget.jwtSecret!.isNotEmpty) {
final jwt = JWT(config);
final token = jwt.sign(SecretKey(widget.jwtSecret!), algorithm: JWTAlgorithm.HS256);
config['token'] = token;
}
```
The key difference: Instead of just adding a pre-made token to the config, we now:
1. Create a JWT from the **entire config object**
2. Sign it with the **secret key** using HS256 algorithm
3. Add the resulting signed token to the config
### 3. Updated Example App
**File: `example/lib/main.dart`**
```dart
// Old:
static const String jwtToken = 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...';
// New:
static const String jwtSecret = '6Yr6DGoVV3ACS6GtVgdH453mXxLftd6Q';
// Usage:
OnlyOfficeViewer(
onlyOfficeServerUrl: onlyOfficeServerUrl,
fileUrl: currentDoc.url,
jwtSecret: jwtSecret, // Pass the secret, not a pre-made token
)
```
### 4. Updated Tests
**File: `test/onlyoffice_viewer_unit_test.dart`**
- Updated all test cases to use `jwtSecret` instead of `token`
- Added new test to verify JWT token generation and validation
- Updated TestHelper to match the real implementation
## How to Use
### For Your Server Configuration
You need to provide the **JWT secret** that matches your OnlyOffice server configuration. This secret is configured in your OnlyOffice server's `local.json`:
```json
{
"services": {
"CoAuthoring": {
"secret": {
"inbox": {
"string": "YOUR_SECRET_HERE"
},
"outbox": {
"string": "YOUR_SECRET_HERE"
}
},
"token": {
"enable": {
"browser": true,
"request": {
"inbox": true,
"outbox": true
}
}
}
}
}
}
```
### Example Usage
```dart
OnlyOfficeViewer(
onlyOfficeServerUrl: 'https://document.23544.com/',
fileUrl: 'https://example.com/document.pptx',
jwtSecret: '6Yr6DGoVV3ACS6GtVgdH453mXxLftd6Q', // Your server's JWT secret
)
```
## What Gets Signed
The JWT token now contains the entire configuration object:
```dart
{
'document': {
'fileType': 'pptx',
'key': 'sha256_hash_of_url',
'title': 'document.pptx',
'url': 'https://example.com/document.pptx',
},
'documentType': 'slide',
'editorConfig': {
'mode': 'view',
'lang': 'zh-CN'
},
'type': 'mobile',
}
```
This entire object is signed with HS256 algorithm using your secret, and the resulting JWT is added as the `token` field.
## Security Note
⚠️ **Never commit your JWT secret to version control!**
Store it securely:
- Use environment variables
- Use secure configuration management
- Use encrypted secret storage

# 高级功能开发总结
## 概述
基于对 ONLYOFFICE 官方 Android 和 iOS 项目的深入研究,我创建了一个**高级功能分支**,提供了完整的编辑器控制能力。
## 官方项目研究成果
### 从官方 Android 项目学到的关键实现
1. **WebView 桥接模式**
- 使用 `addJavascriptInterface` 在原生代码和 JavaScript 之间通信
- 实现双向通信Flutter ↔ JavaScript ↔ DocsAPI
2. **图片插入流程**
```
用户点击插入图片
→ 编辑器触发 onRequestInsertImage 事件
→ Flutter 打开图片选择器
→ 上传图片到服务器
→ 调用 docEditor.insertImage() 方法
```
3. **文件下载处理**
- 拦截下载 URL
- 使用原生下载管理器
- 保存到本地存储
### 从官方 iOS 项目学到的关键实现
1. **WKWebView 消息处理**
- 使用 `WKScriptMessageHandler` 接收消息
- 实现 `evaluateJavaScript` 调用编辑器方法
2. **生命周期管理**
- `onAppReady`: 编辑器应用加载完成
- `onDocumentReady`: 文档加载完成,可以调用方法
- `onDocumentStateChange`: 跟踪文档修改状态
3. **权限和安全**
- 相机/相册权限请求
- 文件访问权限
- JWT 签名验证
## 实现的高级功能
### 1. YxOnlyOfficeAdvancedViewer
完整的高级查看器,提供:
```dart
class YxOnlyOfficeAdvancedViewer extends StatefulWidget {
// WebViewController 访问
final Function(WebViewController controller)? onControllerReady;
// 生命周期事件
final Function()? onDocumentReady;
final Function()? onAppReady;
// 图片插入
final Future<String?> Function()? onRequestImageFromGallery;
final Future<String?> Function()? onRequestImageFromCamera;
// 文件下载
final Future<void> Function(String url, String filename)? onDownloadFile;
// 其他配置...
}
```
### 2. 编辑器方法调用
直接调用 DocsAPI 方法:
```dart
// 插入图片
await viewerState.insertImage('https://example.com/image.jpg');
// 下载文档
await viewerState.downloadAs('pdf');
// 设置审阅模式
await viewerState.setReviewerMode(true);
// 显示修订
await viewerState.showReviewChanges(true);
// 销毁编辑器
await viewerState.destroyEditor();
// 执行自定义 JavaScript
await viewerState.executeJavaScript('window.docEditor.getDocumentName()');
```
### 3. EditorMethodResult
统一的方法调用结果:
```dart
class EditorMethodResult {
final bool success;
final dynamic data;
final String? error;
}
```
### 4. 图片插入完整流程
```dart
// 1. 用户触发插入
onRequestInsertImage: (data) async {
// 2. 选择图片来源
final source = await showDialog(...);
// 3. 打开图片选择器
final image = await ImagePicker().pickImage(source: source);
// 4. 上传到服务器
final imageUrl = await uploadImage(image);
// 5. 插入到文档
await viewerState.insertImage(imageUrl);
}
```
### 5. 文件下载处理
```dart
onDownloadFile: (url, filename) async {
// 1. 下载文件
final response = await http.get(Uri.parse(url));
// 2. 保存到本地
final directory = await getApplicationDocumentsDirectory();
final file = File('${directory.path}/$filename');
await file.writeAsBytes(response.bodyBytes);
// 3. 通知用户
print('文件已保存: ${file.path}');
}
```

bool _isDocumentReady = false;
YxOnlyOfficeAdvancedViewer(
onDocumentReady: () {
setState(() => _isDocumentReady = true);
},
)
// 只在文档准备好后调用方法
if (_isDocumentReady) {
await viewerKey.currentState!.insertImage(url);
}
```
### 2. 错误处理
```dart
final result = await viewerKey.currentState!.downloadAs('pdf');
if (result.success) {
print('成功');
} else {
print('失败: ${result.error}');
// 显示错误提示给用户
}
```
### 3. 内存管理
```dart
@override
void dispose() {
// 在页面销毁时销毁编辑器
viewerKey.currentState?.destroyEditor();
super.dispose();
}
```
## 常见问题
### Q: 如何判断编辑器是否准备好?
A: 监听 `onDocumentReady` 回调:
```dart
bool _isReady = false;
onDocumentReady: () {
setState(() => _isReady = true);
}
```
### Q: 图片插入失败怎么办?
A: 检查:
1. 文档是否已准备好(`onDocumentReady` 已触发)
2. 图片 URL 是否可访问
3. 是否有编辑权限(`mode: 'edit'`
### Q: 如何获取编辑器的当前状态?
A: 使用 `executeJavaScript`
```dart
final result = await viewerKey.currentState!.executeJavaScript('''
if (window.docEditor) {
return {
name: window.docEditor.getDocumentName(),
// 其他信息...
};
}
return null;
''');
```
### Q: 支持哪些下载格式?
A: 支持的格式取决于文档类型:
- **Word**: docx, pdf, txt, rtf, odt, html, epub
- **Excel**: xlsx, pdf, csv, ods
- **PowerPoint**: pptx, pdf, odp

# 权限和网络安全配置指南
## 问题描述
如果遇到 "DocsAPI 未加载成功" 错误,即使服务器可以访问,通常是因为 Android/iOS 的网络安全策略阻止了 WebView 加载外部资源。
## Android 配置
### 1. AndroidManifest.xml
确保在 `android/app/src/main/AndroidManifest.xml` 中添加了以下配置:
```xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<!-- 网络权限 -->
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:usesCleartextTraffic="true"
android:networkSecurityConfig="@xml/network_security_config"
...>
...
</application>
</manifest>
```
### 2. network_security_config.xml
创建文件 `android/app/src/main/res/xml/network_security_config.xml`
```xml
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<!-- 允许所有 HTTPS 连接 -->
<base-config cleartextTrafficPermitted="true">
<trust-anchors>
<certificates src="system" />
<certificates src="user" />
</trust-anchors>
</base-config>
<!-- 允许特定域名的 HTTP 连接(如果需要) -->
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">localhost</domain>
<domain includeSubdomains="true">10.0.2.2</domain>
</domain-config>
</network-security-config>
```
### 3. 目录结构
确保目录结构正确:
```
android/app/src/main/res/
└── xml/
└── network_security_config.xml
```
## iOS 配置
### Info.plist
`ios/Runner/Info.plist` 中添加:
```xml
<key>NSAppTransportSecurity</key>
<dict>
<!-- 允许所有 HTTPS 连接 -->
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
```
或者只允许特定域名(更安全):
```xml
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>document.23544.com</key>
<dict>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<false/>
</dict>
</dict>
</dict>
```
## 验证配置
### 1. 检查文件是否存在
**Android**:
```bash
ls -la example/android/app/src/main/res/xml/network_security_config.xml
```
**iOS**:
```bash
grep -A 5 "NSAppTransportSecurity" example/ios/Runner/Info.plist
```
### 2. 重新构建应用
配置更改后,需要完全重新构建应用:
```bash
# 清理构建缓存
flutter clean
# 重新获取依赖
flutter pub get
# 重新构建
flutter run
```
### 3. 检查日志
运行应用后,查看日志中是否有:
- ✅ `页面加载完成`
- ✅ `DocsAPI loaded successfully`
- ❌ 如果有错误,查看具体的错误信息
## 常见问题
### Q: 配置后仍然无法加载?
**A**: 尝试以下步骤:
1. **完全清理并重建**:
```bash
flutter clean
cd android && ./gradlew clean && cd ..
flutter pub get
flutter run
```
2. **检查网络权限**:
- 确保 AndroidManifest.xml 中有 `INTERNET` 权限
- 确保应用有网络访问权限(在设备设置中检查)
3. **检查服务器证书**:
- 如果使用自签名证书,需要在 `network_security_config.xml` 中添加证书配置
4. **查看详细日志**:
- 运行应用时查看控制台输出
- 查看是否有 JavaScript 错误
### Q: 生产环境是否安全?
**A**: 当前配置允许所有 HTTPS 连接,适合开发环境。生产环境建议:
1. **Android**: 只允许特定域名
```xml
<domain-config cleartextTrafficPermitted="false">
<domain includeSubdomains="true">your-server.com</domain>
</domain-config>
```
2. **iOS**: 只允许特定域名(见上方 iOS 配置示例)
### Q: 是否需要其他权限?
**A**: 对于基础功能,只需要:
- `INTERNET` - 网络访问
- `ACCESS_NETWORK_STATE` - 检查网络状态
如果使用图片插入功能,还需要:
- `CAMERA` - 相机权限
- `READ_EXTERNAL_STORAGE` - 读取存储权限Android
- `WRITE_EXTERNAL_STORAGE` - 写入存储权限Android
## 测试清单
- [ ] AndroidManifest.xml 包含 INTERNET 权限
- [ ] AndroidManifest.xml 引用了 network_security_config
- [ ] network_security_config.xml 文件存在且配置正确
- [ ] iOS Info.plist 包含 NSAppTransportSecurity 配置
- [ ] 执行了 `flutter clean` 和重新构建
- [ ] 在浏览器中可以访问 API 脚本 URL

# DocsAPI 加载错误故障排除指南
## 错误信息
```
📡 事件: onError, 数据: DocsAPI is not loaded. Check server URL.
```
## 常见原因和解决方案
### 1. 服务器 URL 不正确 ⚠️
**问题**: 您使用的是示例 URL `https://doc.example.com/`,这不是一个真实的服务器。
**解决方案**:
- 使用您自己的 ONLYOFFICE Document Server 地址
- 确保服务器地址格式正确(不要有多余的斜杠)
```bash
# ❌ 错误 - 示例 URL
--dart-define ONLYOFFICE_SERVER_URL=https://doc.example.com/
# ✅ 正确 - 您的实际服务器
--dart-define ONLYOFFICE_SERVER_URL=https://your-real-server.com
```
### 2. 服务器无法访问 🌐
**检查步骤**:
1. **在浏览器中测试 API 脚本 URL**:
```
https://your-server.com/web-apps/apps/api/documents/api.js
```
如果无法打开,说明服务器不可访问。
2. **检查网络连接**:
```bash
# 测试服务器是否可达
ping your-server.com
# 或使用 curl
curl -I https://your-server.com/web-apps/apps/api/documents/api.js
```
3. **检查防火墙和代理设置**
### 3. CORS 问题 🔒
**问题**: 服务器可能没有启用 CORS导致 WebView 无法加载脚本。
**解决方案**:
- 在 ONLYOFFICE Document Server 配置中启用 CORS
- 检查服务器的 CORS 响应头
### 4. 脚本路径错误 📁
**检查**: 确保 API 脚本路径正确:
```
https://your-server.com/web-apps/apps/api/documents/api.js
```
**常见错误**:
- ❌ `https://your-server.com/api.js` (缺少路径)
- ❌ `https://your-server.com/web-apps/api.js` (路径不完整)
- ✅ `https://your-server.com/web-apps/apps/api/documents/api.js` (正确)
### 5. 服务器配置问题 ⚙️
**检查 ONLYOFFICE Document Server 配置**:
1. 确保 Document Server 正在运行
2. 检查服务器日志
3. 验证 API 端点是否正常
## 调试步骤
### 步骤 1: 验证服务器 URL
在代码中添加调试输出:
```dart
void main() {
print('=== 服务器配置检查 ===');
print('Server URL: $_serverUrl');
print('File URL: $_fileUrl');
print('Expected API URL: $_serverUrl/web-apps/apps/api/documents/api.js');
print('====================');
runApp(const AdvancedDemoApp());
}
```
### 步骤 2: 在浏览器中测试
1. 打开浏览器
2. 访问 API 脚本 URL:
```
https://your-server.com/web-apps/apps/api/documents/api.js
```
3. 如果能看到 JavaScript 代码,说明服务器正常
4. 如果看到 404 或连接错误,说明服务器配置有问题
### 步骤 3: 检查 WebView 控制台
在应用运行时,查看 WebView 的 JavaScript 控制台输出:
- Android: 使用 `adb logcat` 查看日志
- iOS: 使用 Xcode 控制台查看日志
### 步骤 4: 测试网络连接
```dart
// 在应用启动时测试连接
Future<void> testServerConnection() async {
try {
final url = Uri.parse('$_serverUrl/web-apps/apps/api/documents/api.js');
final response = await http.head(url);
if (response.statusCode == 200) {
print('✅ 服务器连接正常');
} else {
print('❌ 服务器返回错误: ${response.statusCode}');
}
} catch (e) {
print('❌ 无法连接到服务器: $e');
}
}
```
## 快速检查清单
- [ ] 服务器 URL 是真实的,不是示例 URL
- [ ] 服务器 URL 格式正确(没有多余的斜杠)
- [ ] 可以在浏览器中访问 API 脚本 URL
- [ ] 网络连接正常
- [ ] 服务器已启用 CORS
- [ ] Document Server 正在运行
- [ ] 防火墙没有阻止连接
## 常见服务器 URL 格式
### 标准安装
```
https://documentserver.example.com
```
### 子路径安装
```
https://example.com/documentserver
```
### 本地开发
```
http://localhost:8080
```
**注意**: 本地开发时Android 模拟器使用 `10.0.2.2` 而不是 `localhost`:
```
http://10.0.2.2:8080
```
## 获取帮助
如果以上步骤都无法解决问题:
1. **检查服务器日志**: 查看 ONLYOFFICE Document Server 的日志文件
2. **查看浏览器控制台**: 在浏览器中打开编辑器,查看是否有错误
3. **测试官方示例**: 在浏览器中测试 ONLYOFFICE 官方示例是否正常工作
4. **联系服务器管理员**: 确认服务器配置是否正确
## 改进的错误信息
新版本的插件会提供更详细的错误信息,包括:
- 完整的脚本 URL
- 检查清单
- 建议的解决方案
请确保使用最新版本的代码。
