}五、JavaScript应用逻辑实现
5.1 核心API调用模块
实现与ModelScope API交互的核心功能处理异步任务和错误处理
// 配置常量
const MODEL_SCOPE_BASE_URL https://api-inference.modelscope.cn/;
const API_KEY your_modelscope_api_key_here; // 实际应用中应从安全来源获取// 通用请求头
const commonHeaders {Authorization: Bearer ${API_KEY},Content-Type: application/json,
};// API调用函数
class ModelScopeAPI {/*** 提交图像生成任务* param {Object} params - 生成参数* returns {Promisestring} 任务ID*/static async submitImageGenerationTask(params) {try {const response await axios.post(${MODEL_SCOPE_BASE_URL}v1/images/generations,{model: params.model,prompt: params.prompt,negative_prompt: params.negativePrompt || undefined,size: params.size,seed: params.seed || undefined,steps: params.steps,guidance: params.guidance},{headers: {...commonHeaders,X-ModelScope-Async-Mode: true}});if (response.data response.data.task_id) {return response.data.task_id;} else {throw new Error(Invalid response format: missing task_id);}} catch (error) {console.error(Error submitting generation task:, error);throw new Error(Failed to submit task: ${error.response?.data?.message || error.message});}}/*** 检查任务状态* param {string} taskId - 任务ID* returns {PromiseObject} 任务状态和结果*/static async checkTaskStatus(taskId) {try {const response await axios.get(${MODEL_SCOPE_BASE_URL}v1/tasks/${taskId},{headers: {...commonHeaders,X-ModelScope-Task-Type: image_generation}});return response.data;} catch (error) {console.error(Error checking task status:, error);throw new Error(Failed to check task status: ${error.response?.data?.message || error.message});}}/*** 轮询任务结果* param {string} taskId - 任务ID* param {number} interval - 轮询间隔(毫秒)* param {number} timeout - 超时时间(毫秒)* returns {Promisestring} 生成的图像URL*/static async pollTaskResult(taskId, interval 5000, timeout 120000) {const startTime Date.now();return new Promise((resolve, reject) {const poll async () {// 检查超时if (Date.now() - startTime timeout) {reject(new Error(Task polling timeout));return;}try {const taskStatus await this.checkTaskStatus(taskId);switch (taskStatus.task_status) {case SUCCEED:if (taskStatus.output_images taskStatus.output_images.length 0) {resolve(taskStatus.output_images[0]);} else {reject(new Error(Task succeeded but no image URL returned));}break;case FAILED:reject(new Error(Task failed: ${taskStatus.message || Unknown error}));break;case PENDING:case RUNNING:// 继续轮询setTimeout(poll, interval);break;default:reject(new Error(Unknown task status: ${taskStatus.task_status}));}} catch (error) {reject(error);}};// 开始轮询poll();});}
}5.2 用户界面交互逻辑
实现表单处理、状态管理和用户交互功能
// 应用状态管理
class AppState {constructor() {this.currentTaskId null;this.generationHistory JSON.parse(localStorage.getItem(imageGenerationHistory)) || [];this.isGenerating false;}addToHistory(entry) {// 保留最近20条记录this.generationHistory.unshift(entry);if (this.generationHistory.length 20) {this.generationHistory this.generationHistory.slice(0, 20);}// 保存到本地存储localStorage.setItem(imageGenerationHistory, JSON.stringify(this.generationHistory));// 更新UIthis.renderHistory();}clearHistory() {this.generationHistory [];localStorage.removeItem(imageGenerationHistory);this.renderHistory();}renderHistory() {const historyList document.getElementById(historyList);if (!historyList) return;historyList.innerHTML ;if (this.generationHistory.length 0) {historyList.innerHTML div classtext-center text-muted py-3i classbi bi-clock-history d-block fs-1/ip classmt-2暂无生成历史/p/div;return;}this.generationHistory.forEach((item, index) {const historyItem document.createElement(a);historyItem.href #;historyItem.className list-group-item list-group-item-action history-item;historyItem.innerHTML div classd-flex w-100 justify-content-betweenh6 classmb-1${item.prompt.substring(0, 60)}${item.prompt.length 60 ? ... : }/h6small${new Date(item.timestamp).toLocaleTimeString()}/small/divp classmb-1模型: ${item.model} | 尺寸: ${item.size}/psmall classtext-muted点击查看详情/small;historyItem.addEventListener(click, (e) {e.preventDefault();this.showHistoryItem(item);});historyList.appendChild(historyItem);});}showHistoryItem(item) {// 填充表单document.getElementById(promptInput).value item.prompt;document.getElementById(negativePrompt).value item.negativePrompt || ;document.getElementById(modelSelect).value item.model;document.getElementById(sizeSelect).value item.size;document.getElementById(stepsInput).value item.steps;document.getElementById(guidanceInput).value item.guidance;if (item.seed) {document.getElementById(seedInput).value item.seed;}// 显示图像this.displayGeneratedImage(item.imageUrl, item.prompt);}
}// 初始化应用
const appState new AppState();// 页面加载完成后初始化
document.addEventListener(DOMContentLoaded, function() {// 渲染历史记录appState.renderHistory();// 表单提交处理document.getElementById(imageForm).addEventListener(submit, handleFormSubmit);// 清除历史按钮document.getElementById(clearHistory).addEventListener(click, () {if (confirm(确定要清除所有生成历史吗此操作不可撤销。)) {appState.clearHistory();}});// 重新生成按钮document.getElementById(regenerateBtn).addEventListener(click, () {document.getElementById(imageForm).dispatchEvent(new Event(submit));});
});/*** 处理表单提交* param {Event} e - 表单提交事件*/
async function handleFormSubmit(e) {e.preventDefault();if (appState.isGenerating) {alert(当前已有任务正在处理中请稍候...);return;}// 获取表单数据const formData {prompt: document.getElementById(promptInput).value.trim(),negativePrompt: document.getElementById(negativePrompt).value.trim(),model: document.getElementById(modelSelect).value,size: document.getElementById(sizeSelect).value,steps: parseInt(document.getElementById(stepsInput).value),guidance: parseFloat(document.getElementById(guidanceInput).value),seed: document.getElementById(seedInput).value ? parseInt(document.getElementById(seedInput).value) : undefined};// 验证输入if (!formData.prompt) {alert(请输入提示词);return;}if (formData.prompt.length 2000) {alert(提示词长度不能超过2000个字符);return;}// 更新UI状态setGeneratingState(true);try {// 提交生成任务const taskId await ModelScopeAPI.submitImageGenerationTask(formData);appState.currentTaskId taskId;// 轮询获取结果const imageUrl await ModelScopeAPI.pollTaskResult(taskId);// 显示生成的图像displayGeneratedImage(imageUrl, formData.prompt);// 保存到历史记录appState.addToHistory({...formData,imageUrl,timestamp: new Date().toISOString(),taskId});} catch (error) {console.error(Generation error:, error);alert(生成失败: ${error.message});} finally {// 恢复UI状态setGeneratingState(false);}
}/*** 显示生成的图像* param {string} imageUrl - 图像URL* param {string} prompt - 提示词*/
function displayGeneratedImage(imageUrl, prompt) {const placeholder document.getElementById(placeholder);const resultContainer document.getElementById(resultContainer);const generatedImage document.getElementById(generatedImage);const downloadBtn document.getElementById(downloadBtn);// 隐藏占位符显示结果区域placeholder.classList.add(d-none);resultContainer.classList.remove(d-none);// 设置图像和下载链接generatedImage.src imageUrl;generatedImage.alt prompt;downloadBtn.href imageUrl;downloadBtn.download generated-${Date.now()}.jpg;
}/*** 设置生成状态UI* param {boolean} isGenerating - 是否正在生成*/
function setGeneratingState(isGenerating) {appState.isGenerating isGenerating;const generateBtn document.getElementById(generateBtn);const loadingSpinner document.getElementById(loadingSpinner);if (isGenerating) {generateBtn.disabled true;loadingSpinner.classList.remove(d-none);generateBtn.innerHTML 生成中...;} else {generateBtn.disabled false;loadingSpinner.classList.add(d-none);generateBtn.innerHTML 生成图像;}
}5.3 高级功能实现
实现图像放大、批量生成和高级参数控制等扩展功能
// 高级功能类
class AdvancedFeatures {/*** 使用Real-ESRGAN放大图像* param {string} imageUrl - 原始图像URL* param {number} scale - 放大倍数(2, 4)* returns {Promisestring} 放大后的图像URL*/static async upscaleImage(imageUrl, scale 2) {// 这里需要实现图像放大逻辑// 可以使用其他ModelScope模型或第三方APIconsole.log(Upscaling image from ${imageUrl} with scale ${scale});// 模拟实现 - 实际应用中应调用相应的放大APIreturn new Promise((resolve) {setTimeout(() {resolve(imageUrl); // 实际应用中应返回放大后的URL}, 2000);});}/*** 批量生成图像* param {Object} baseParams - 基础参数* param {number} count - 生成数量* param {Arraynumber} seeds - 种子数组(可选)* returns {PromiseArraystring} 生成的图像URL数组*/static async batchGenerate(baseParams, count, seeds []) {const results [];for (let i 0; i count; i) {try {const params {...baseParams};// 使用指定种子或随机生成if (seeds[i] ! undefined) {params.seed seeds[i];} else {params.seed Math.floor(Math.random() * 1000000);}const taskId await ModelScopeAPI.submitImageGenerationTask(params);const imageUrl await ModelScopeAPI.pollTaskResult(taskId);results.push({url: imageUrl,seed: params.seed,index: i});// 更新进度if (typeof this.onBatchProgress function) {this.onBatchProgress(i 1, count);}} catch (error) {console.error(Batch generation failed for item ${i}:, error);results.push({error: error.message,index: i});}}return results;}/*** 生成图像变体* param {string} imageUrl - 原始图像URL* param {string} prompt - 提示词* param {number} similarity - 与原始图像的相似度(0-1)* returns {Promisestring} 变体图像URL*/static async generateVariant(imageUrl, prompt, similarity 0.7) {// 这里需要实现图像变体生成逻辑// 可以使用img2img功能的ModelScope模型console.log(Generating variant for ${imageUrl} with similarity ${similarity});// 模拟实现 - 实际应用中应调用相应的img2img APIreturn new Promise((resolve) {setTimeout(() {resolve(imageUrl); // 实际应用中应返回变体图像的URL}, 2000);});}
}// 扩展UI功能
function initAdvancedFeatures() {// 添加放大按钮const buttonGroup document.createElement(div);buttonGroup.className btn-group mt-2;buttonGroup.innerHTML button typebutton classbtn btn-sm btn-outline-secondary idupscale2x放大2x/buttonbutton typebutton classbtn btn-sm btn-outline-secondary idupscale4x放大4x/buttonbutton typebutton classbtn btn-sm btn-outline-info idgenerateVariant生成变体/button;document.querySelector(#resultContainer .d-grid).appendChild(buttonGroup);// 添加批量生成UIconst batchSection document.createElement(div);batchSection.className mt-4;batchSection.innerHTML h6批量生成/h6div classinput-group mb-2input typenumber classform-control idbatchCount placeholder生成数量 value4 min1 max10button classbtn btn-outline-primary typebutton idstartBatch开始批量生成/button/divdiv classprogress d-none idbatchProgressdiv classprogress-bar roleprogressbar stylewidth: 0%/div/divdiv classmt-2 row g-2 idbatchResults/div;document.getElementById(resultContainer).appendChild(batchSection);// 事件监听document.getElementById(upscale2x).addEventListener(click, () handleUpscale(2));document.getElementById(upscale4x).addEventListener(click, () handleUpscale(4));document.getElementById(generateVariant).addEventListener(click, handleGenerateVariant);document.getElementById(startBatch).addEventListener(click, handleBatchGenerate);
}// 处理图像放大
async function handleUpscale(scale) {const imageUrl document.getElementById(generatedImage).src;try {setGeneratingState(true);const upscaledUrl await AdvancedFeatures.upscaleImage(imageUrl, scale);// 创建新标签页显示放大后的图像window.open(upscaledUrl, _blank);} catch (error) {alert(放大失败: ${error.message});} finally {setGeneratingState(false);}
}// 处理批量生成

}// 页面加载完成后初始化高级功能
document.addEventListener(DOMContentLoaded, initAdvancedFeatures);六、性能优化与最佳实践
6.1 前端性能优化策略
实现前端性能优化提升用户体验
// 图像懒加载和缓存管理
class ImageCacheManager {constructor(maxSize 50) {this.cache new Map();this.maxSize maxSize;}set(key, imageData) {if (this.cache.size this.maxSize) {// 移除最旧的项const oldestKey this.cache.keys().next().value;this.cache.delete(oldestKey);}this.cache.set(key, {data: imageData,timestamp: Date.now()});}get(key) {const item this.cache.get(key);if (item) {// 更新访问时间item.timestamp Date.now();return item.data;}return null;}clear() {this.cache.clear();}
}// 初始化缓存
const imageCache new ImageCacheManager();// 优化图像加载
function loadImageWithCache(url, prompt) {return new Promise((resolve, reject) {// 检查缓存const cached imageCache.get(url);if (cached) {resolve(cached);return;}const img new Image();img.onload () {// 缓存图像imageCache.set(url, img);resolve(img);};img.onerror () {reject(new Error(Failed to load image: ${url}));};img.src url;img.alt prompt;});
}// 替换原有的图像显示逻辑
async function displayGeneratedImageOptimized(imageUrl, prompt) {const placeholder document.getElementById(placeholder);const resultContainer document.getElementById(resultContainer);const generatedImage document.getElementById(generatedImage);placeholder.classList.add(d-none);resultContainer.classList.remove(d-none);// 显示加载中状态generatedImage.src assets/loading-spinner.gif;generatedImage.alt 加载中...;try {const img await loadImageWithCache(imageUrl, prompt);generatedImage.src img.src;generatedImage.alt prompt;// 更新下载链接const downloadBtn document.getElementById(downloadBtn);downloadBtn.href imageUrl;downloadBtn.download generated-${Date.now()}.jpg;} catch (error) {console.error(Error loading image:, error);generatedImage.src assets/error-placeholder.png;generatedImage.alt 图像加载失败;}
}6.2 API调用优化与错误处理
增强API调用的健壮性和错误处理能力
// 增强的API调用类

}七、部署与安全考虑
7.1 后端代理实现
为了保护API密钥并处理跨域问题实现一个简单的Node.js代理服务器
// server.js - Express代理服务器
const express require(express);
const axios require(axios);
const cors require(cors);
require(dotenv).config();const app express();
const port process.env.PORT || 3000;// 中间件
app.use(cors());
app.use(express.json());// ModelScope API配置
const MODEL_SCOPE_BASE_URL https://api-inference.modelscope.cn/;
const API_KEY process.env.MODELSCOPE_API_KEY;// 通用请求头
const commonHeaders {Authorization: Bearer ${API_KEY},Content-Type: application/json
};// 代理图像生成请求
app.post(/api/generate, async (req, res) {try {const response await axios.post(${MODEL_SCOPE_BASE_URL}v1/images/generations,req.body,{headers: {...commonHeaders,X-ModelScope-Async-Mode: true}});res.json(response.data);} catch (error) {console.error(Proxy error:, error.response?.data || error.message);res.status(error.response?.status || 500).json({error: error.response?.data?.message || error.message});}
});// 代理任务状态检查
app.get(/api/tasks/:taskId, async (req, res) {try {const response await axios.get(${MODEL_SCOPE_BASE_URL}v1/tasks/${req.params.taskId},{headers: {...commonHeaders,X-ModelScope-Task-Type: image_generation}});res.json(response.data);} catch (error) {console.error(Proxy error:, error.response?.data || error.message);res.status(error.response?.status || 500).json({error: error.response?.data?.message || error.message});}
});// 启动服务器
app.listen(port, () {console.log(Proxy server running on port ${port});
});7.2 环境配置与安全实践
创建环境配置文件和安全最佳实践
// 前端配置
const CONFIG {API_BASE_URL: window.location.hostname localhost ? http://localhost:3000/api : /api,MAX_HISTORY_ITEMS: 20,DEFAULT_PARAMS: {model: black-forest-labs/FLUX.1-Krea-dev,size: 1024x1024,steps: 30,guidance: 7.5},// 其他配置项...
};// 更新API调用以使用代理
class SecureModelScopeAPI {static async submitImageGenerationTask(params) {const response await axios.post(${CONFIG.API_BASE_URL}/generate,params);if (response.data response.data.task_id) {return response.data.task_id;} else {throw new Error(Invalid response format from proxy);}}static async checkTaskStatus(taskId) {const response await axios.get(${CONFIG.API_BASE_URL}/tasks/${taskId});return response.data;}
}创建环境变量文件(.env)

NODE_ENVproduction八、未来功能扩展方向
8.1 模型管理与比较
实现多模型支持与结果比较功能
// 模型管理类
class ModelManager {constructor() {this.availableModels [{id: black-forest-labs/FLUX.1-Krea-dev,name: FLUX.1,description: 高质量的图像生成模型,supportedSizes: [512x512, 768x768, 1024x1024],maxSteps: 100,defaultSteps: 30},{id: MAILAND/majicflus_v1,name: MajicFLUS v1,description: 适用于动漫风格的图像生成,supportedSizes: [512x512, 768x768],maxSteps: 50,defaultSteps: 25},{id: qwen-qwen1.5-72b-image,name: Qwen-Image 72B,description: 支持多模态输入的大型模型,supportedSizes: [512x512, 768x768, 1024x1024, 1664x1664],maxSteps: 100,defaultSteps: 40}];}getModelById(id) {return this.availableModels.find(model model.id id);}updateFormForModel(modelId) {const model this.getModelById(modelId);if (!model) return;// 更新尺寸选项const sizeSelect document.getElementById(sizeSelect);sizeSelect.innerHTML ;model.supportedSizes.forEach(size {const option document.createElement(option);option.value size;option.textContent size;if (size 1024x1024) option.selected true;sizeSelect.appendChild(option);});// 更新步数限制const stepsInput document.getElementById(stepsInput);stepsInput.max model.maxSteps;if (parseInt(stepsInput.value) model.maxSteps) {stepsInput.value model.defaultSteps;}// 显示模型信息this.showModelInfo(model);}showModelInfo(model) {// 创建或更新模型信息面板let infoPanel document.getElementById(modelInfoPanel);if (!infoPanel) {infoPanel document.createElement(div);infoPanel.id modelInfoPanel;infoPanel.className alert alert-info mt-3;document.getElementById(imageForm).appendChild(infoPanel);}infoPanel.innerHTML strong${model.name}/strong: ${model.description}brsmall支持尺寸: ${model.supportedSizes.join(, )} | 最大步数: ${model.maxSteps}/small;}
}// 初始化模型管理
const modelManager new ModelManager();// 模型选择变化时更新表单
document.getElementById(modelSelect).addEventListener(change, (e) {modelManager.updateFormForModel(e.target.value);
});// 页面加载时初始化
document.addEventListener(DOMContentLoaded, () {modelManager.updateFormForModel(document.getElementById(modelSelect).value);
});8.2 高级提示词工具
实现提示词建议、模板和效果预览功能
// 提示词工具类
class PromptTools {constructor() {this.templates [{name: 肖像,prompt: portrait of a {subject}, detailed face, professional photography, sharp focus, studio lighting,negativePrompt: blurry, low quality, distorted, watermark},{name: 风景,prompt: landscape of {subject}, majestic, beautiful lighting, hyperdetailed, photorealistic,negativePrompt: blurry, people, buildings, low resolution},{name: 动漫,prompt: anime style {subject}, vibrant colors, clean lines, detailed background, official art,negativePrompt: realistic, photorealistic, 3d render, low quality}];this.suggestions [masterpiece, best quality, 4k, 8k, ultra detailed,sharp focus, studio lighting, dramatic lighting, professional photography];}applyTemplate(templateName, subject) {const template this.templates.find(t t.name templateName);if (!template) return null;return {prompt: template.prompt.replace({subject}, subject),negativePrompt: template.negativePrompt};}enhancePrompt(basePrompt) {// 添加一些通用质量提示词如果尚未包含const enhanced basePrompt.split(,);this.suggestions.forEach(suggestion {if (!basePrompt.toLowerCase().includes(suggestion)) {enhanced.push(suggestion);}});return enhanced.join(, );}
}// 初始化提示词工具
const promptTools new PromptTools();// 添加快捷模板按钮
function initPromptTemplates() {const templateGroup document.createElement(div);templateGroup.className btn-group w-100 my-2;templateGroup.innerHTML button typebutton classbtn btn-sm btn-outline-secondary prompt-template data-template肖像肖像/buttonbutton typebutton classbtn btn-sm btn-outline-secondary prompt-template data-template风景风景/buttonbutton typebutton classbtn btn-sm btn-outline-secondary prompt-template data-template动漫动漫/buttonbutton typebutton classbtn btn-sm btn-outline-info idenhancePrompt增强提示词/button;document.getElementById(promptInput).parentNode.appendChild(templateGroup);// 模板按钮事件document.querySelectorAll(.prompt-template).forEach(button {button.addEventListener(click, (e) {const templateName e.target.dataset.template;const subject prompt(请输入${templateName}的主题:, a beautiful woman);if (subject) {const result promptTools.applyTemplate(templateName, subject);if (result) {document.getElementById(promptInput).value result.prompt;document.getElementById(negativePrompt).value result.negativePrompt;}}});});// 增强提示词按钮document.getElementById(enhancePrompt).addEventListener(click, () {const currentPrompt document.getElementById(promptInput).value;if (currentPrompt) {document.getElementById(promptInput).value promptTools.enhancePrompt(currentPrompt);}});
}// 页面加载时初始化提示词工具
document.addEventListener(DOMContentLoaded, initPromptTemplates);九、结论与展望
