文档管理系统包括哪些内容?五分钟带你讲清楚!

// 版本控制核心逻辑示例
public class DocumentVersion
{
    public int VersionId { get; set; }
    public string DocumentId { get; set; }
    public int VersionNumber { get; set; }
    public string FilePath { get; set; }
    public DateTime CreatedDate { get; set; }
    public string CreatedBy { get; set; }
    public string ChangeDescription { get; set; }
    
    public void CreateNewVersion(string documentId, string filePath)
    {
        // 版本创建逻辑
        VersionNumber = GetLatestVersion(documentId) + 1;
        CreatedDate = DateTime.Now;
    }
}

// 审计日志记录功能
class AuditLogger {
    logDocumentAccess(documentId, userId, action) {
        const logEntry = {
            timestamp: new Date().toISOString(),
            documentId: documentId,
            userId: userId,
            action: action,
            ipAddress: this.getClientIP()
        };
        
        // 存储审计日志
        this.saveAuditLog(logEntry);
    }
    
    getAccessHistory(documentId) {
        // 查询文档访问历史
        return this.auditLogs.filter(log => log.documentId === documentId);
    }
}

// 文档协作状态管理
public class CollaborationService
{
    public void LockDocument(string documentId, string userId)
    {
        // 锁定文档防止冲突
        var document = GetDocument(documentId);
        if (!document.IsLocked)
        {
            document.Lock(userId);
            SaveDocumentState(document);
        }
    }
    
    public void ReleaseLock(string documentId, string userId)
    {
        // 释放文档锁
        var document = GetDocument(documentId);
        if (document.LockedBy == userId)
        {
            document.Unlock();
            SaveDocumentState(document);
        }
    }
}

// RESTful API 接口示例
class DocumentAPI {
    // 上传文档
    async uploadDocument(file, metadata) {
        const formData = new FormData();
        formData.append('file', file);
        formData.append('metadata', JSON.stringify(metadata));
        
        const response = await fetch('/api/documents', {
            method: 'POST',
            body: formData
        });
        
        return await response.json();
    }
    
    // 搜索文档
    async searchDocuments(query, filters) {
        const params = new URLSearchParams({
            q: query,
            ...filters
        });
        
        const response = await fetch(`/api/documents/search?${params}`);
        return await response.json();
    }
}
