SP1教育专版浏览器360安全浏览器教育版Chromium 91内核数据库人大金仓V8需兼容PHP的PDO扩展安全要求通过等保2.0三级认证原系统痛点UEditor在信创环境下出现幽灵字符问题粘贴后随机出现乱码图片上传功能在国产防火墙拦截下频繁失败表格样式在WPS与Office间切换时完全错乱二、技术选型在信创生态中寻找平衡点1. 候选方案深度测试方案Word粘贴准确率信创兼容性教育功能扩展开发周期TinyMCE 678%基础样式★★☆☆☆需二次开发4周WangEditor 565%★★★☆☆有限2周改写UEditor72%★★☆☆☆困难3周自主开发核心模块92%★★★★☆高度灵活5周关键发现教育行业特殊需求需支持LaTeX公式粘贴来自MathType批改功能需与现有阅卷系统API对接需实现纯净模式过滤Word中的宏病毒风险信创环境技术壁垒银河麒麟系统缺少libpng12库影响图片处理360教育版浏览器禁用了部分Clipboard API人大金仓数据库对BLOB类型支持有限三、开发实施分阶段攻克核心难题阶段一前端架构重构Vue3实现// EduEditor.vue - 核心组件import{ref,onMounted}fromvueimport{parseWordContent}from./word-parser// 自定义解析器import{uploadToJinKing}from./db-adapter//

word-parser.js - 信创环境专用解析器exportconstparseWordContentasync(html){// 创建隔离解析环境constparserdocument.createElement(div)parser.innerHTMLhtml// 教育行业特殊处理MathType公式constmathTypesparser.querySelectorAll([class*MathType])mathTypes.forEach(el{el.outerHTML${el.textContent}})//

图片提取与Base64转换适配内网constimages[]constimgElementsparser.querySelectorAll(img)for(constimgofimgElements){if(img.src.startsWith(file://)){// 处理本地文件需用户授权images.push({type:local,path:img.src.replace(file://,)})img.src__IMG_PLACEHOLDER_(images.length-1)__}elseif(!img.src.startsWith(data:)){//

db-adapter.php - 人大金仓专用适配器classJinKingDB{private$pdo;publicfunction__construct(){try{$this-pdonewPDO(kingbase:hostlocalhost;port54321;dbnameEDU_SYSTEM,edu_admin,SecurePass123);$this-pdo-setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);}catch(PDOException$e){thrownewException(数据库连接失败:

);$stmt-execute([$filename,$totalChunks]);$attachmentId$this-pdo-lastInsertId();// 存储各分块for($i0;$i$totalChunks;$i){$chunksubstr($data,$i*$chunkSize,$chunkSize);$stmt$this-pdo-prepare( INSERT INTO

.$e-getMessage());returnfalse;}}}四、信创环境专项优化1. 字体兼容方案/* 强制使用教育系统预装字体 */.edu-content{font-family:方正书宋_GBK,汉仪楷体_GBK,思源黑体 CN,sans-serif;}/* 公式特殊处理 */.math-formula{font-family:Latin Modern Math,Cambria Math;background:#f5f5f5;padding:2px 4px;border-radius:3px;}2. 浏览器兼容补丁// 修复360教育版浏览器的Clipboard APIif(navigator.userAgent.includes(360SE-Edu)){constnativePasteHTMLDocument.prototype.paste;HTMLDocument.prototype.pastefunction(e){// 延迟处理以绕过浏览器安全限制setTimeout((){constcustomEventnewCustomEvent(eduPaste,{detail:{html:window.clipboardData.getData(text/html),text:window.clipboardData.getData(text)}});this.dispatchEvent(customEvent);},100);if(nativePaste)nativePaste.apply(this,arguments);};}五、测试与部署1.
