        "aspect_ratio": "9:16"
    }
}

🏗️ 技术实现

1. BowongAI基础服务类（通用服务）

// src/services/bowongai.service.ts
@Injectable()
export class BowongAIService {
  private readonly webhookUrl = 'https://n8n.bowongai.com/webhook/76f92dbf-785f-4add-96b5-a108174b7c14';
  private readonly environment = 'https://bowongai-test--text-video-agent-fastapi-app.modal.run';

  // 通用图生图接口 - 各模板传入自己的参数
  async imageToImage(options: {
    prompt: string;
    imageUrl: string;
    model?: string;
  }): Promise<ImageToImageResponse>

  // 通用图生视频接口 - 各模板传入自己的参数
  async imageToVideo(options: {
    imagePrompt: string;
    videoPrompt: string;
    imageUrl: string;
    duration?: number;
    aspectRatio?: string;
    imageModel?: string;
    videoModel?: string;
  }): Promise<ImageToVideoResponse>
}

2. 具体模板实现（各自定制）

换装模板（图生图）

@Injectable()
export class OutfitChangeTemplate extends ImageGenerateTemplate {
  readonly metadata = {
    code: 'outfit_change_v1',
    name: '智能换装',
    category: '换装',
    creditCost: 15,
  };

  constructor(private readonly bowongAI: BowongAIService) {}

  async execute(input, context) {
    // 换装模板专用提示词
    const prompt = this.buildOutfitChangePrompt(input);

    return await this.bowongAI.imageToImage({
      prompt,
      imageUrl: input.inputImage,
      model: 'gemini-2.5-flash-image-preview', // 换装专用模型
    });
  }

  private buildOutfitChangePrompt(input) {
    return `Please convert this photo into a highly detailed character model wearing ${input.clothingDescription}. Place in front of the model a delicate, colorful box featuring the printed image of the person from the photo...`;
  }
}

人像增强模板（图生图）

@Injectable()
export class PortraitEnhanceTemplate extends ImageGenerateTemplate {
  readonly metadata = {
    code: 'portrait_enhance_v1',
    name: '人像增强',
    category: '人像处理',
    creditCost: 12,
  };

  constructor(private readonly bowongAI: BowongAIService) {}

  async execute(input, context) {
    // 人像增强专用提示词
    const prompt = this.buildPortraitPrompt(input);

    return await this.bowongAI.imageToImage({
      prompt,
      imageUrl: input.inputImage,
      model: 'gemini-2.5-flash-image-preview',
    });
  }

  private buildPortraitPrompt(input) {
    return `Enhance this portrait photo to professional quality. Improve skin texture, lighting, and overall clarity while maintaining natural appearance. ${input.enhanceLevel === 'subtle' ? 'Apply subtle enhancements' : 'Apply dramatic improvements'}...`;
  }
}

动态视频模板（图生视频）

@Injectable()
export class DynamicVideoTemplate extends VideoGenerateTemplate {
  readonly metadata = {
    code: 'dynamic_video_v1',
    name: '动态视频',
    category: '视频生成',
    creditCost: 45,
  };

  constructor(private readonly bowongAI: BowongAIService) {}

  async execute(input, context) {
    // 动态视频专用提示词
    const imagePrompt = this.buildImagePrompt(input);
    const videoPrompt = this.buildVideoPrompt(input);

    return await this.bowongAI.imageToVideo({
      imagePrompt,
      videoPrompt,
      imageUrl: input.inputImage,
      duration: input.duration || 4,
      aspectRatio: input.aspectRatio || '9:16',
      imageModel: 'gemini-2.5-flash-image-preview',
      videoModel: '302/MiniMax-Hailuo-02',
    });
  }

  private buildImagePrompt(input) {
    return `Convert this image for dynamic video generation with ${input.motionType} motion effects...`;
  }

  private buildVideoPrompt(input) {
    return `Create ${input.motionType} animation with ${input.intensity} intensity. ${input.customPrompt || 'Natural movement'}`;
  }
}

🎨 模板化提示词设计

换装模板提示词

private buildOutfitChangePrompt(input: OutfitChangeInput): string {
  const styleMap = {
    casual: 'casual everyday wear',
    formal: 'formal business attire',
    vintage: 'vintage retro style',
    modern: 'modern contemporary fashion',
    elegant: 'elegant sophisticated style'
  };

  const styleText = styleMap[input.style] || 'casual';

  return `Please convert this photo into a highly detailed character model wearing ${input.clothingDescription}.
Style: ${styleText}.
Place in front of the model a delicate, colorful box featuring the printed image of the person from the photo.
Behind the box, show a computer screen actively displaying the modeling process.
Set the entire scene in a bright, stylish indoor environment.
Ensure the lighting is crisp and luminous, highlighting both the model and its packaging.`;
}

人像增强模板提示词

private buildPortraitPrompt(input: PortraitEnhanceInput): string {
  const enhancementLevels = {
    subtle: 'Apply subtle professional enhancements',
    moderate: 'Apply moderate quality improvements',
    dramatic: 'Apply dramatic professional transformation'
  };

  const enhancement = enhancementLevels[input.enhanceLevel] || 'moderate';

  return `${enhancement} to this portrait photo.
Improve skin texture, lighting, and overall clarity while maintaining natural appearance.
Focus on professional photography quality with ${input.lightingStyle || 'natural'} lighting.
Preserve the person's unique features and expressions.`;
}

动态视频模板提示词

private buildVideoPrompt(input: DynamicVideoInput): string {
  const motionTypes = {
    gentle: 'gentle subtle movements',
    dynamic: 'dynamic energetic motion',
    cinematic: 'cinematic smooth transitions',
    artistic: 'artistic creative effects'
  };

  const motion = motionTypes[input.motionType] || 'gentle';

  return `Create ${motion} with ${input.intensity || 'medium'} intensity.
${input.customPrompt || 'Natural lifelike movement'}.
Maintain character consistency throughout the animation.`;
}

  },
  body: JSON.stringify({
    inputImage: 'https://cdn.roasmax.cn/upload/e9066bf20fb546b09ece65d6fbcf2dd3.png',
    videoPrompt: '让角色动起来',
    duration: 6,
    resolution: '9:16'
  })
});

✅ 基础服务架构优势

🏗️ 分层设计

BowongAI基础服务层: 提供通用的API调用能力
模板业务层: 各模板实现自己的业务逻辑和提示词
参数定制层: 每个模板可以传入不同的参数配置

🎯 模板独立性

✅ 每个模板有独立的提示词逻辑
✅ 每个模板有独立的参数验证
✅ 每个模板有独立的积分消耗
✅ 每个模板可以选择不同的AI模型

📊 当前实现状态

✅ BowongAI基础服务实现
✅ 换装模板（图生图）- 15积分
✅ 图生视频模板 - 50积分
✅ 人像增强模板 - 12积分
✅ 模板工厂和模块配置
✅ 环境配置和前端示例

🚀 扩展新模板步骤

继承对应的抽象类
实现execute方法，调用BowongAI基础服务
定义模板专用的提示词构建逻辑
配置模板特定的参数和积分
在工厂类中注册新模板

示例：添加风格转换模板

@Injectable()
export class StyleTransferTemplate extends ImageGenerateTemplate {
  async execute(input, context) {
    const prompt = this.buildStylePrompt(input); // 风格转换专用提示词

    return await this.bowongAI.imageToImage({
      prompt,
      imageUrl: input.inputImage,
      model: 'gemini-2.5-flash-image-preview',
    });
  }

  private buildStylePrompt(input) {
    return `Transform this image into ${input.targetStyle} style...`;
  }
}

现在BowongAI作为基础服务，支持各种模板的个性化定制！🎉
