1 编辑器配置修改1.1 新增上传word json配置1.2 修改编辑器配置文件1.2.1 在工具栏上新增按钮1.2.2 新增语言配置1.2.3 修改过滤配置2 添加相关功能2.1 安装PHPword2.2 自定义文件转换类2.3 编辑器实现导入操作当前功能基于PHP，其它语言流程大抵相同。
大概流程：
1. 将docx文件上传到服务器中
2. 使用PHPoffice/PHPword实现将word转换为HTML
3. 将HTML代码返回并赋值到编辑器中
1 编辑器配置修改
1.1 新增上传word json配置
在ueditor\php\config.json中新增如下配置：
/* 上传word配置 */"wordActionName": "wordupload", /* 执行上传视频的action名称 */"wordFieldName": "upfile", /* 提交的视频表单名称 */"wordPathFormat": "/public/uploads/word/{yyyy}{mm}{dd}/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */"wordMaxSize": 102400000, /* 上传大小限制，单位B，默认100MB */"wordAllowFiles": [".docx"] /* 仅支持docx格式的word */
1.2 修改编辑器配置文件
1.2.1 在工具栏上新增按钮
在ueditor\ueditor.config.js文件中，新增按钮名称"wordupload"，并添加鼠标悬浮提示，如下所示：
//工具栏上的所有的功能按钮和下拉框，可以在new编辑器的实例时选择自己需要的重新定义, toolbars: [['fullscreen', 'source', '|', 'undo', 'redo', '|','bold', 'italic', 'underline', 'fontborder', 'strikethrough', 'superscript', 'subscript', 'removeformat', 'formatmatch', 'autotypeset', 'blockquote', 'pasteplain', '|', 'forecolor', 'backcolor', 'insertorderedlist', 'insertunorderedlist', 'selectall', 'cleardoc', '|','rowspacingtop', 'rowspacingbottom', 'lineheight', '|','customstyle', 'paragraph', 'fontfamily', 'fontsize', '|','directionalityltr', 'directionalityrtl', 'indent', '|','justifyleft', 'justifycenter', 'justifyright', 'justifyjustify', '|', 'touppercase', 'tolowercase', '|','link', 'unlink', 'anchor', '|', 'imagenone', 'imageleft', 'imageright', 'imagecenter', '|','simpleupload', 'insertimage', 'emotion', 'scrawl', 'insertvideo', 'music', 'attachment', 'map', 'gmap', 'insertframe', 'insertcode', 'webapp', 'pagebreak', 'template', 'background', '|','horizontal', 'date', 'time', 'spechars', 'snapscreen', 'wordimage', '|','inserttable', 'deletetable', 'insertparagraphbeforetable', 'insertrow', 'deleterow', 'insertcol', 'deletecol', 'mergecells', 'mergeright', 'mergedown', 'splittocells', 'splittorows', 'splittocols', 'charts', '|','print', 'preview', 'searchreplace', 'drafts', 'help', 'wordupload']]//当鼠标放在工具栏上时显示的tooltip提示,留空支持自动多语言配置，否则以配置值为准,labelMap:{'wordupload': '上传word文件',}
在ueditor\themes\default\images\目录下新增按钮图标"word_upload.png"：
在ueditor\themes\default\css\ueditor.css文件中新增按钮样式：
.edui-for-wordupload .edui-icon {width: 16px;height: 16px;background: url(../images/word_upload.png) no-repeat 2px 2px !important;}
最后在ueditor\ueditor.all.js文件中editorui["simpleupload"] = function (editor){}后面添加如下代码：
/* word上传 */editorui["wordupload"] = function (editor) {var name = 'wordupload',ui = new editorui.Button({className:'edui-for-' + name,title:editor.options.labelMap[name] || editor.getLang("labelMap." + name) || '',onclick:function () {},theme:editor.options.theme,showText:false});editorui.buttons[name] = ui;editor.addListener('ready', function() {var b = ui.getDom('body'),iconSpan = b.children[0];editor.fireEvent('worduploadbtnready', iconSpan);});editor.addListener('selectionchange', function (type, causeByUi, uiReady) {var state = editor.queryCommandState(name);if (state == -1) {ui.setDisabled(true);ui.setChecked(false);} else {if (!uiReady) {ui.setDisabled(false);ui.setChecked(state);}}});return ui;};
最终样式如下：
1.2.2 新增语言配置
在ueditor\lang\zh-cn\zh-cn.js文件中在"simpleupload"配置下方新增以下配置：
'simpleupload':{'exceedSizeError': '文件大小超出限制','exceedTypeError': '文件格式不允许','jsonEncodeError': '服务器返回格式错误','loading':"正在上传...",'loadError':"上传错误",'errorLoadConfig': '后端配置项没有正常加载，上传插件不能正常使用！'},'wordupload':{'exceedSizeError': '文件大小超出限制','exceedTypeError': '文件格式不允许','jsonEncodeError': '服务器返回格式错误','loading':"正在上传...",'loadError':"上传错误",'errorLoadConfig': '后端配置项没有正常加载，上传插件不能正常使用！'},
在ueditor\lang\zh-cn\en.js文件中在"simpleupload"配置下方新增以下配置：
'simpleupload':{'exceedSizeError': 'File Size Exceed','exceedTypeError': 'File Type Not Allow','jsonEncodeError': 'Server Return Format Error','loading':"loading...",'loadError':"load error",'errorLoadConfig': 'Server config not loaded, upload can not work.',},'wordupload':{'exceedSizeError': 'File Size Exceed','exceedTypeError': 'File Type Not Allow','jsonEncodeError': 'Server Return Format Error','loading':"loading...",'loadError':"load error",'errorLoadConfig': 'Server config not loaded, upload can not work.',},
1.2.3 修改过滤配置
由于导入word时，编辑器会自动过滤掉图片等样式，所以需取消过滤
在ueditor\ueditor.config.js文件中修改如下配置：
// xss 过滤是否开启,inserthtml等操作,xssFilterRules: false//input xss过滤,inputXssFilter: false//output xss过滤,outputXssFilter: false
在ueditor\ueditor.all.js文件中，修改UE.plugins[‘defaultfilter’]，新增return ;如下所示：
// plugins/defaultfilter.js///import core///plugin 编辑器默认的过滤转换机制UE.plugins['defaultfilter'] = function () {return;var me = this;me.setOpt({'allowDivTransToP':true,'disabledTableInTable':true});……
2 添加相关功能
2.1 安装PHPword
composer require phpoffice/phpword
2.2 自定义文件转换类
实现上传文件，并将文件转换为HTML
直接将ueditor自带的上传文件"ueditor\php\Uploader.class.php"类复制到自定义类相同目录下
自定义WordToHtmlController.class.php文件：
<?phpclass WordToHtmlController{public function index(){require 'vendor/autoload.php';$base64 = "upload";$config = array("pathFormat" => '/public/uploads/word/{yyyy}{mm}{dd}/{time}{rand:6}',"maxSize" => 102400000,"allowFiles" => [".docx"]);$fieldName = 'upfile';include 'Uploader.class.php';$up = new Uploader($fieldName, $config, $base64);$path = ltrim($up->getFileInfo()['url'], '/');// $phpWord = \PhpOffice\PhpWord\IOFactory::load('public/uploads/word/1029/test.docx');$phpWord = \PhpOffice\PhpWord\IOFactory::load($path);// 直接输出到页面显示// $phpWord->save('php://output', 'HTML');$xmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'HTML');header("Content-Type:text/html; charset=utf-8");exit($this->replaceImageSrc($xmlWriter->getContent()));// exit($xmlWriter->getContent());}/*** 将HTML代码中的所有图片地址替换* @param $content string 要查找的内容* @return string*/private function replaceImageSrc($content){$preg = '/(\s+src\s?\=)\s?[\'|"]([^\'|"]*)/is'; // 匹配img标签的正则表达式preg_match_all($preg, $content, $allImg); // 匹配所有的imgif (!$allImg)return $content;foreach ($allImg[0] as $k => $v) {$old = ltrim($v, '" src=');preg_match('/^(data:\s*image\/(\w+);base64,)/', $old, $temp);$tempType = $temp[2]; // 获取类型// 判断目录是否存在，不存在时创建$tempFilePath = 'public/uploads/word_images/' . date('Y-m-d', time());if (!file_exists($tempFilePath))mkdir($tempFilePath);// 拼接完整路径$tempFileName = $tempFilePath . '/word_image_' . time() . $k . '.' . $tempType;$base64 = str_replace($temp[1], '', $old);file_put_contents($tempFileName, base64_decode($base64));// 替换路径字符串$content = str_replace($old, $tempFileName, $content);}return $content;}}
2.3 编辑器实现导入操作
在ueditor\ueditor.all.js文件中UE.plugin.register('simpleupload', function (){})下方新增如下方法：
/*** @description* word上传:点击按钮,直接选择文件上传*/UE.plugin.register('wordupload', function (){var me = this,isLoaded = false,containerBtn;function initUploadBtn(){var w = containerBtn.offsetWidth || 20,h = containerBtn.offsetHeight || 20,btnIframe = document.createElement('iframe'),btnStyle = 'display:block;width:' + w + 'px;height:' + h + 'px;overflow:hidden;border:0;margin:0;padding:0;position:absolute;top:0;left:0;filter:alpha(opacity=0);-moz-opacity:0;-khtml-opacity: 0;opacity: 0;cursor:pointer;';domUtils.on(btnIframe, 'load', function(){var timestrap = (+new Date()).toString(36),wrapper,btnIframeDoc,btnIframeBody;btnIframeDoc = (btnIframe.contentDocument || btnIframe.contentWindow.document);btnIframeBody = btnIframeDoc.body;wrapper = btnIframeDoc.createElement('div');wrapper.innerHTML = '<form id="edui_form_' + timestrap + '" target="edui_iframe_' + timestrap + '" method="POST" enctype="multipart/form-data" action="' + me.getOpt('serverUrl') + '" ' +'style="' + btnStyle + '">' +'<input id="edui_input_' + timestrap + '" type="file" accept="application/msword" name="' + me.options.wordFieldName + '" ' +'style="' + btnStyle + '">' +'</form>' +'<iframe id="edui_iframe_' + timestrap + '" name="edui_iframe_' + timestrap + '" style="display:none;width:0;height:0;border:0;margin:0;padding:0;position:absolute;"></iframe>';wrapper.className = 'edui-' + me.options.theme;wrapper.id = me.ui.id + '_iframeupload';btnIframeBody.style.cssText = btnStyle;btnIframeBody.style.width = w + 'px';btnIframeBody.style.height = h + 'px';btnIframeBody.appendChild(wrapper);if (btnIframeBody.parentNode) {btnIframeBody.parentNode.style.width = w + 'px';btnIframeBody.parentNode.style.height = w + 'px';}var form = btnIframeDoc.getElementById('edui_form_' + timestrap);var input = btnIframeDoc.getElementById('edui_input_' + timestrap);var iframe = btnIframeDoc.getElementById('edui_iframe_' + timestrap);domUtils.on(input, 'change', function(){if(!input.value) return;var loadingId = 'loading_' + (+new Date()).toString(36);var allowFiles = me.getOpt('wordAllowFiles');me.focus();me.execCommand('inserthtml', '<img class="loadingclass" id="' + loadingId + '" src="' + me.options.themePath + me.options.theme +'/images/spacer.gif" title="' + (me.getLang('wordupload.loading') || '') + '" >');function callback(){try{// 获取到内容var body = (iframe.contentDocument || iframe.contentWindow.document).body;// 获取加载中图片并关闭var loader = me.document.getElementById(loadingId);loader.removeAttribute('id');domUtils.removeClasses(loader, 'loadingclass');// 向编辑器赋值me.setContent(body.innerHTML, false);// me.execCommand('insertHtml', body.innerHTML);}catch(er){showErrorLoader && showErrorLoader(me.getLang('wordupload.loadError'));}form.reset();domUtils.un(iframe, 'load', callback);}function showErrorLoader(title){if(loadingId) {var loader = me.document.getElementById(loadingId);loader && domUtils.remove(loader);me.fireEvent('showmessage', {'id': loadingId,'content': title,'type': 'error','timeout': 4000});}}/* 判断后端配置是否没有加载成功 */if (!me.getOpt('wordActionName')) {errorHandler(me.getLang('autoupload.errorLoadConfig'));return;}// 判断文件格式是否错误var filename = input.value,fileext = filename ? filename.substr(filename.lastIndexOf('.')):'';if (!fileext || (allowFiles && (allowFiles.join('') + '.').indexOf(fileext.toLowerCase() + '.') == -1)) {showErrorLoader(me.getLang('wordupload.exceedTypeError'));return;}domUtils.on(iframe, 'load', callback);// 上传操作// form.action = utils.formatUrl(imageActionUrl + (imageActionUrl.indexOf('?') == -1 ? '?':'&') + params);// 替换请求地址为框架后台地址form.action = "/admin.php?m=fwordToHtml&a=index"form.method = "post"form.submit();});var stateTimer;me.addListener('selectionchange', function () {clearTimeout(stateTimer);stateTimer = setTimeout(function() {var state = me.queryCommandState('wordupload');if (state == -1) {input.disabled = 'disabled';} else {input.disabled = false;}}, 400);});isLoaded = true;});btnIframe.style.cssText = btnStyle;containerBtn.appendChild(btnIframe);}return {bindEvents:{'ready': function() {//设置loading的样式utils.cssRule('loading','.loadingclass{display:inline-block;cursor:default;background: url(\''+ this.options.themePath+ this.options.theme +'/images/loading.gif\') no-repeat center center transparent;border:1px solid #cccccc;margin-right:1px;height: 22px;width: 22px;}\n' +'.loaderrorclass{display:inline-block;cursor:default;background: url(\''+ this.options.themePath+ this.options.theme +'/images/loaderror.png\') no-repeat center center transparent;border:1px solid #cccccc;margin-right:1px;height: 22px;width: 22px;' +'}',this.document);},/* 初始化word上传按钮 */'worduploadbtnready': function(type, container) {containerBtn = container;me.afterConfigReady(initUploadBtn);}},outputRule: function(root){utils.each(root.getNodesByTagName('img'),function(n){if (/\b(loaderrorclass)|(bloaderrorclass)\b/.test(n.getAttr('class'))) {n.parentNode.removeChild(n);}});},commands: {'wordupload': {queryCommandState: function () {return isLoaded ? 0:-1;}}}}});
然后在同文件下的btnCmds变量中添加上自定义的按钮：
//为工具栏添加按钮，以下都是统一的按钮触发命令，所以写在一起var btnCmds = ['undo', 'redo', 'formatmatch','bold', 'italic', 'underline', 'fontborder', 'touppercase', 'tolowercase','strikethrough', 'subscript', 'superscript', 'source', 'indent', 'outdent','blockquote', 'pasteplain', 'pagebreak','selectall', 'print','horizontal', 'removeformat', 'time', 'date', 'unlink','insertparagraphbeforetable', 'insertrow', 'insertcol', 'mergeright', 'mergedown', 'deleterow','deletecol', 'splittorows', 'splittocols', 'splittocells', 'mergecells', 'deletetable', 'drafts', 'wordupload'];
至此，配置完成，结果示意图：
