在 H5 营销活动中引入 Stable Diffusion 动态生成 AI辅助前端脚手架工具设计 的落地实践 在 H5 营销活动中引入 Stable Diffusion 动态生成 AI辅助前端脚手架工具设计 的落地实践前言我是大山哥。上周帮客户做一个 H5 营销活动时设计师小美愁眉苦脸地说大山哥这次活动要做 50 张不同风格的海报我一个人根本来不及我笑了笑别急咱们用 AI 来搞定结果呢我们用 Stable Diffusion 自动生成了上百张海报素材前端脚手架自动搭建整个活动页面一天就搞定了兄弟现在做 H5 营销活动不会用 AI 生成内容就落伍了今天我就来分享如何在 H5 营销活动中引入 Stable Diffusion实现 AI 辅助前端脚手架工具设计的落地实践。一、技术架构设计1.1 系统架构图graph TD A[用户请求] -- B[前端脚手架] B -- C[AI 内容生成服务] C -- D[Stable Diffusion API] D -- E[图片生成] E -- F[图片优化] F -- G[CDN 存储] G -- B C -- H[文案生成] H -- B B -- I[页面渲染]1.2 模块职责模块职责技术栈前端脚手架快速生成活动页面模板React ViteAI 内容服务调用 Stable Diffusion 和文案 APINode.js Express图片处理图片压缩、格式转换、水印添加SharpCDN 存储图片静态资源托管阿里云 OSS二、Stable Diffusion 集成方案2.1 API 服务封装import axios from axios; interface ImageGenerationParams { prompt: string; negativePrompt?: string; width?: number; height?: number; steps?: number; seed?: number; model?: string; } interface GenerationResult { success: boolean; imageUrl?: string; error?: string; seed?: number; } class StableDiffusionService { private baseUrl: string; private apiKey: string; constructor(baseUrl: string, apiKey: string) { this.baseUrl baseUrl; this.apiKey apiKey; } async generateImage(params: ImageGenerationParams): PromiseGenerationResult { try { const response await axios.post( ${this.baseUrl}/sdapi/v1/txt2img, { prompt: params.prompt, negative_prompt: params.negativePrompt || blurry, low quality, text, watermark, width: params.width || 1024, height: params.height || 1024, steps: params.steps || 20, seed: params.seed || -1, cfg_scale: 7, sampler_name: Euler a, model: params.model || v1-5-pruned-emaonly.safetensors, }, { headers: { Content-Type: application/json, Authorization: Bearer ${this.apiKey}, }, responseType: json, } ); if (response.data.images response.data.images.length 0) { const base64Image response.data.images[0]; const imageBuffer Buffer.from(base64Image, base64); // 上传到 CDN const cdnUrl await this.uploadToCDN(imageBuffer); return { success: true, imageUrl: cdnUrl, seed: response.data.seed, }; } return { success: false, error: No image generated }; } catch (error) { return { success: false, error: error instanceof Error ?
