### JavaScript 集成核心代码
```javascript
// office-preview.js
class OnlyOfficeManager {
constructor(containerId, config = {}) {
this.containerId = containerId;
this.config = {
documentServerUrl: 'https://onlyoffice.yourdomain.com',

}
// 初始化编辑器

if (!container) {
throw new Error(`容器 ${this.containerId} 未找到`);
}
// 生成 JWT token
const token = this.generateJWT(documentConfig);
const editorConfig = {

}
},
documentType: this.getDocumentType(documentConfig.fileType),
editorConfig: {
mode: documentConfig.editable ? 'edit' : 'view',
lang: 'zh-CN',
callbackUrl: documentConfig.callbackUrl,

};
// 创建编辑器实例
this.editor = new DocsAPI.DocEditor(this.containerId, editorConfig);
this.updateStatus('编辑器已初始化');
}
// 生成 JWT token
generateJWT(payload) {
if (!this.config.jwtSecret) return null;
// 简化的 JWT 生成(实际项目中应使用完整的 JWT 库)
const header = {
alg: "HS256",
<"live.gold.mfkzq.cn">
<"sport.gold.mfkzq.cn">
<"football.gold.mfkzq.cn">
typ: "JWT"
};
const encodedHeader = btoa(JSON.stringify(header));
const encodedPayload = btoa(JSON.stringify(payload));
const signature = this.createSignature(encodedHeader, encodedPayload);
return `${encodedHeader}.${encodedPayload}.${signature}`;
}
createSignature(encodedHeader, encodedPayload) {
// 实际项目中应使用 crypto 库生成签名
const crypto = require('crypto');
return crypto
.createHmac('sha256', this.config.jwtSecret)
.update(encodedHeader + '.' + encodedPayload)
.digest('base64');
}
// 根据文件类型确定文档类型
getDocumentType(fileType) {
const documentTypes = {
'docx': 'text',
'doc': 'text',
'odt': 'text',
'txt': 'text',
'xlsx': 'spreadsheet',
'xls': 'spreadsheet',
'ods': 'spreadsheet',
'pptx': 'presentation',
'ppt': 'presentation',
'odp': 'presentation',
'pdf': 'pdf'
};
return documentTypes[fileType.toLowerCase()] || 'text';
}
// 加载文档
loadDocument(documentConfig) {
this.updateStatus('正在加载文档...');
try {
this.initEditor(documentConfig);
this.currentDocument = documentConfig;
// 监听编辑器事件
this.setupEventListeners();
} catch (error) {
console.error('文档加载失败:', error);
this.updateStatus('文档加载失败');
}
}
// 设置事件监听器
setupEventListeners() {
if (window.DocsAPI) {
window.DocsAPI.=> {
this.updateStatus('文档已就绪');
};
window.DocsAPI.=> {
console.error('编辑器错误:', event);
this.updateStatus('发生错误: ' + event.data);
};
window.DocsAPI.=> {
this.handleDocumentChange(event);
};
window.DocsAPI.=> {
this.handleSaveAs(event);
};
}
}
// 处理文档变化
handleDocumentChange(event) {
const { data } = event;
console.log('文档状态变化:', data);
if (data && data.actions) {
this.updateStatus('文档已修改');
}
}
// 处理另存为请求
handleSaveAs(event) {
const { url, title, data } = event;

}
<"basketball.gold.mfkzq.cn">

// 下载文件
downloadFile(url, filename) {
const link = document.createElement('a');
link.href = url;
link.download = filename;
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
}
// 更新状态
updateStatus(message) {
const statusElement = document.getElementById('status');

}
}
// 销毁编辑器
destroy() {
if (this.editor) {
this.editor.destroyEditor();
this.editor = null;
}
this.updateStatus('编辑器已关闭');
}
}
// 使用示例
const officeManager = new OnlyOfficeManager('officeContainer', {

});
// 加载文档函数
function loadDocument() {
const documentConfig = {
title: '示例文档.docx',

// 下载文档函数
function downloadDocument() {
if (officeManager.currentDocument) {
officeManager.downloadFile(
officeManager.currentDocument.url,
officeManager.currentDocument.title
);
}
}
```
## 服务端回调处理
### 回调接口实现
OnlyOffice 在文档保存时会调用配置的回调 URL:
```javascript
// server/callback-handler.js
const express = require('express');
const router = express.Router();
const fs = require('fs');
const path = require('path');
// OnlyOffice 回调处理
router.post('/onlyoffice/callback', async (req, res) => {
try {
const { body } = req;
console.log('收到 OnlyOffice 回调:', JSON.stringify(body, null, 2));
// 验证请求合法性
if (!this.validateCallback(body)) {
return res.status(403).json({ error: '非法请求' });
}
const { status, key, url } = body;
switch (status) {
case 1: // 文档正在编辑
await this.handleEditing(key);
break;
case 2: // 文档已准备保存
await this.handleReadyForSave(key);
break;
case 3: // 文档保存出错
await this.handleSaveError(key);
break;
case 4: // 文档已关闭无变化
await this.handleClosedNoChanges(key);
break;
case 6: // 文档正在保存
await this.handleSaving(key, url);
break;
case 7: // 文档强制保存出错
await this.handleForceSaveError(key);
break;
default:
console.warn('未知状态:', status);
}
res.json({ error: 0 }); // 告诉 OnlyOffice 处理成功
} catch (error) {
console.error('回调处理失败:', error);
res.status(500).json({ error: 1 });
}
});
// 验证回调请求
validateCallback(callbackData) {
// 验证 JWT token(如果启用)
if (this.config.jwtEnabled) {
const token = req.headers['authorization'];
if (!this.verifyJWT(token, callbackData)) {
return false;
}
}
// 验证关键字段
if (!callbackData.key || !callbackData.status) {
return false;
}
return true;
}
// 处理文档保存
async handleSaving(documentKey, documentUrl) {
try {
console.log(`文档 ${documentKey} 正在保存`);
// 下载保存的文档
const savedDocument = await this.downloadDocument(documentUrl);
// 更新本地存储
await this.updateDocumentStorage(documentKey, savedDocument);
// 通知相关用户
await this.notifyUsers(documentKey, 'document_saved');
console.log(`文档 ${documentKey} 保存完成`);
} catch (error) {
console.error(`文档 ${documentKey} 保存失败:`, error);
throw error;
}
<"m.CFL.mfkzq.cn">
<"share.CFL.mfkzq.cn">
<"ei.CFL.mfkzq.cn">
}
// 下载文档
async downloadDocument(documentUrl) {
const response = await fetch(documentUrl);
if (!response.ok) {
throw new Error(`下载失败: ${response.statusText}`);
}
return await response.buffer();
}
// 更新文档存储
async updateDocumentStorage(documentKey, documentBuffer) {
const filePath = path.join(this.config.storagePath, `${documentKey}.docx`);
// 确保目录存在
const dir = path.dirname(filePath);
if (!fs.existsSync(dir)) {
fs.mkdirSync(dir, { recursive: true });
}
// 保存文件
fs.writeFileSync(filePath, documentBuffer);
// 更新数据库记录
await this.updateDocumentRecord(documentKey, {
lastModified: new Date(),
fileSize: documentBuffer.length
});
}
module.exports = router;
```
## 高级功能实现
### 权限控制系统
```javascript
// permission-manager.js
class PermissionManager {
constructor() {
this.permissions = new Map();
}
// 设置文档权限
setDocumentPermissions(documentKey, permissions) {
this.permissions.set(documentKey, {
...permissions,
createdAt: new Date(),
updatedAt: new Date()
});
}
// 验证用户权限
validateUserPermission(documentKey, userId, action) {
const docPermissions = this.permissions.get(documentKey);
if (!docPermissions) {
return false;
}
const userPermissions = docPermissions.users[userId];
if (!userPermissions) {
return docPermissions.defaultPermissions.includes(action);
}
return userPermissions.includes(action);
}
// 生成文档配置
generateDocumentConfig(documentKey, userId) {
const permissions = this.permissions.get(documentKey);
if (!permissions) {
throw new Error('文档权限未设置');
}
const userCanEdit = this.validateUserPermission(documentKey, userId, 'edit');
const userCanDownload = this.validateUserPermission(documentKey, userId, 'download');
const userCanPrint = this.validateUserPermission(documentKey, userId, 'print');
return {
document: {
permissions: {
edit: userCanEdit,
download: userCanDownload,
print: userCanPrint,
review: userCanEdit
}
},
editorConfig: {
mode: userCanEdit ? 'edit' : 'view',
user: {
id: userId,
name: this.getUserName(userId)
}
}
};
}
// 获取用户信息
getUserName(userId) {
// 从数据库或用户服务获取用户信息
const users = {
'user1': '张三',
'user2': '李四',
'user3': '王五'
};
return users[userId] || '匿名用户';
}
}
// 使用示例
const permissionManager = new PermissionManager();
// 设置文档权限
permissionManager.setDocumentPermissions('doc-123', {
users: {
'user1': ['view', 'edit', 'download', 'print'],
'user2': ['view', 'download'],
'user3': ['view']
},
defaultPermissions: ['view']
});
<"movie.CFL.mfkzq.cn">
<"live.CFL.mfkzq.cn">
<"sport.CFL.mfkzq.cn">
// 生成带权限的文档配置
const userConfig = permissionManager.generateDocumentConfig('doc-123', 'user2');
```
### 文件格式转换服务
```javascript
// file-converter.js
const fs = require('fs');
const path = require('path');
const { promisify } = require('util');
class FileConverter {
constructor(onlyOfficeService) {
this.>
}
// 转换为 PDF
async convertToPdf(inputPath, outputPath) {
try {
const fileExtension = path.extname(inputPath).toLowerCase();
// 检查文件格式支持
if (!this.isFormatSupported(fileExtension)) {
throw new Error(`不支持的格式: ${fileExtension}`);
}
// 使用 OnlyOffice 进行转换
const pdfBuffer = await this.onlyOfficeService.convertFile(
inputPath,
'pdf'
);
// 保存转换结果
await promisify(fs.writeFile)(outputPath, pdfBuffer);
console.log(`文件已转换为 PDF: ${outputPath}`);
return outputPath;
} catch (error) {
console.error('文件转换失败:', error);
throw error;
}
}
// 检查格式支持
isFormatSupported(extension) {
const supportedFormats = [
'.docx', '.doc', '.odt', '.txt', '.rtf',
'.xlsx', '.xls', '.ods', '.csv',
'.pptx', '.ppt', '.odp'
];
return supportedFormats.includes(extension);
}
// 批量转换
async batchConvert(files, targetFormat) {
const results = [];
for (const file of files) {
try {
const outputPath = await this.convertToPdf(
file.inputPath,
file.outputPath
);
results.push({
file: file.name,
status: 'success',
outputPath: outputPath
});
} catch (error) {
results.push({
file: file.name,
status: 'error',
error: error.message
});
}
}
return results;
}
}
module.exports = FileConverter;
```
