  id: 'tiktok_auth',
  name: 'TikTok Authentication',
  description: 'Handles TikTok OAuth2.0 authentication flow',
  params: {
    code: { type: 'string', required: true, description: 'Authorization code' },
  },
  request: {
    url: () => 'https://open-api.tiktok.com/oauth/access_token/',
    method: 'POST',
    headers: () => ({
      'Content-Type': 'application/x-www-form-urlencoded',
    }),
    body: (params) => ({
      client_key: process.env.TIKTOK_CLIENT_KEY,
      client_secret: process.env.TIKTOK_CLIENT_SECRET,
      code: params.code,
      grant_type: 'authorization_code',
    }),
  },
  transformResponse: async (response) => {
    const data = await response.json();
    return {
      success: true,
      output: {
        access_token: data.access_token,
        refresh_token: data.refresh_token,
        expires_in: data.expires_in,
        open_id: data.open_id,
      },
    };
  },
};

3.2 热点内容追踪系统

构建基于多数据源的热点追踪工作流：

实现代码示例（热点分析工具）：

export const trendAnalysisTool: ToolConfig = {
  id: 'trend_analysis',
  name: 'Hot Trend Analysis',
  description: 'Analyzes trending topics for TikTok content creation',
  params: {
    trends: { type: 'array', required: true, description: 'Array of trending topics' },
    niche: { type: 'string', required: true, description: 'Target content niche' },
  },
  request: {
    // 调用LLM分析热点与 niche 的匹配度
    url: () => 'https://api.openai.com/v1/chat/completions',
    method: 'POST',
    headers: (params) => ({
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${process.env.OPENAI_API_KEY}`,
    }),
    body: (params) => ({
      model: 'gpt-4o',
      messages: [
        {
          role: 'system',
          content: `You are a TikTok trend analyst. Rate each trend (1-100) based on relevance to ${params.niche}. Provide engagement prediction and content angles.`,
        },
        { role: 'user', content: `Analyze these trends: ${JSON.stringify(params.trends)}` },
      ],
      response_format: { type: 'json_object' },
    }),
  },
  // 处理LLM响应，提取结构化数据
  transformResponse: async (response) => ({
    success: true,
    output: await response.json(),
  }),
};

3.3 视频内容自动化生成

3.3.1 多模态内容生成流程

3.3.2 视频脚本生成工具配置

// 在sim工作流中配置LLM视频脚本生成
{
  "id": "video_script_generator",
  "type": "llm_block",
  "name": "Video Script Generator",
  "provider": "openai",
  "model": "gpt-4o",
  "system_prompt": "You are a professional TikTok video scriptwriter. Generate a 60-second video script based on the following structure:\n1. Hook (0-3s): Attention-grabbing opening\n2. Problem (3-10s): Present the problem\n3. Solution (10-45s): Show the solution\n4. CTA (45-60s): Clear call to action\nInclude camera angles, transitions, and text overlays.",
  "inputs": [
    { "name": "trend_topic", "type": "string", "description": "Trending topic to base the video on" },
    { "name": "product_info", "type": "string", "description": "Product/service information" },

    { "name": "music_suggestions", "type": "array", "description": "Recommended music tracks" }
  ]
}

3.4 视频发布与状态追踪

利用sim的HTTP工具实现视频发布功能：

// TikTok视频发布工具实现
export const tiktokVideoUploadTool: ToolConfig = {
  id: 'tiktok_video_upload',
  name: 'TikTok Video Upload',
  description: 'Uploads video to TikTok and schedules publishing',
  params: {
    access_token: { type: 'string', required: true, description: 'TikTok access token' },

    method: 'POST',
    headers: (params) => ({
      'Authorization': `Bearer ${params.access_token}`,
    }),
    formData: (params) => {
      const formData = new FormData();
      formData.append('video', fs.createReadStream(params.video_path));
      formData.append('caption', params.caption);
      if (params.schedule_time) {
        formData.append('publish_time', new Date(params.schedule_time).getTime().toString());
      }
      return formData;
    },
  },
  transformResponse: async (response) => {
    const data = await response.json();
    return {
      success: data.status === 'success',
      output: {
        video_id: data.video_id,
        status: data.status,
        publish_time: data.publish_time,
        analytics_url: `https://analytics.tiktok.com/video/${data.video_id}`,
      },
      error: data.status !== 'success' ? data.message : undefined,
    };
  },
};

四、高级功能开发

4.1 多账号矩阵管理系统

// 账号轮换与负载均衡逻辑
export class TikTokAccountManager {
  private accounts: TikTokAccount[];
  private accountUsage: Map<string, number>;
  
  constructor(accounts: TikTokAccount[]) {
    this.accounts = accounts;
    this.accountUsage = new Map(accounts.map(acc => [acc.id, 0]));
  }
  
  // 基于多种因素选择最佳账号
  selectOptimalAccount(criteria: AccountSelectionCriteria): TikTokAccount {
    // 1. 过滤不符合条件的账号
    let candidates = this.accounts.filter(acc => 
      acc.niche.includes(criteria.niche) && 
      acc.status === 'active' &&
      this.isAccountWithinRateLimits(acc)
    );
    
    // 2. 应用权重算法选择账号
    return this.applySelectionAlgorithm(candidates, criteria);
  }
  
  // 实现权重选择算法
  private applySelectionAlgorithm(
    candidates: TikTokAccount[], 
    criteria: AccountSelectionCriteria
  ): TikTokAccount {
    // 基于历史表现、发布频率、粉丝匹配度等计算得分
    const scoredCandidates = candidates.map(acc => ({
      account: acc,
      score: this.calculateAccountScore(acc, criteria)
    }));
    
    // 选择得分最高的账号
    return scoredCandidates.sort((a, b) => b.score - a.score)[0].account;
  }
  
  // 检查账号是否在API速率限制内
  private isAccountWithinRateLimits(account: TikTokAccount): boolean {
    const usage = this.accountUsage.get(account.id) || 0;
    const hourlyLimit = account.plan === 'business' ? 100 : 50;
    
    // 简单的速率限制检查
    return usage < hourlyLimit;
  }
  
  // 计算账号匹配度得分
  private calculateAccountScore(
    account: TikTokAccount, 
    criteria: AccountSelectionCriteria
  ): number {
    let score = 0;
    
    // 粉丝匹配度 (30%)
    score += this.calculateAudienceMatchScore(account, criteria.targetAudience) * 0.3;
    
    // 历史表现 (30%)
    score += this.calculatePerformanceScore(account) * 0.3;
    
    // 发布频率均衡 (20%)
    score += (1 / (this.accountUsage.get(account.id) || 1)) * 0.2;
    
    // 内容新鲜度 (20%)
    score += this.calculateContentFreshnessScore(account, criteria.contentType) * 0.2;
    
    return score;
  }
  
  // 其他辅助方法...
}

4.2 数据驱动的内容优化

4.3 异常处理与系统监控

// 构建健壮的错误处理机制
export class TikTokIntegrationErrorHandler {
  private errorRecoveryStrategies: Record<string, ErrorRecoveryStrategy> = {
    // API速率限制错误处理
    'rate_limit_exceeded': {
      retry: true,
      retryDelay: (attempt) => Math.pow(2, attempt) * 1000, // 指数退避
      maxRetries: 5,
      fallback: 'switch_account',
    },
    
    // 认证错误处理
    'authentication_failed': {
      retry: true,
      retryDelay: 1000,
      maxRetries: 2,
      fallback: 'refresh_token',
    },
    
    // 视频处理失败
    'video_processing_failed': {
      retry: true,
      retryDelay: 5000,
      maxRetries: 3,
      fallback: 'transcode_alternative_format',
    },
    
    // 网络错误处理
    'network_error': {
      retry: true,
      retryDelay: (attempt) => (attempt * 1000) + Math.random() * 500, // 抖动退避
      maxRetries: 4,
      fallback: 'switch_endpoint',
    },
  };
  
  // 执行错误恢复流程
  async handleError(
    error: TikTokApiError,
    context: ErrorContext
  ): Promise<ErrorRecoveryResult> {
    const strategy = this.errorRecoveryStrategies[error.code] || this.defaultStrategy;
    
    // 记录错误详情
    this.logError(error, context);
    
    // 尝试重试
    if (strategy.retry && context.attempt < strategy.maxRetries) {
      return this.attemptRetry(error, context, strategy);
    }
    
    // 执行降级策略
    if (strategy.fallback) {
      return this.executeFallbackStrategy(strategy.fallback, error, context);
    }
    
    // 所有策略失败，返回错误
    return {
      success: false,
      error,
      strategy: 'fail_fast',
    };
  }
  
  // 其他实现方法...
}
