ckeditor粘贴word文档图片的方案

张悦如

当前功能基于PHP，其它语言流程大致相同
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 */
2.修改编辑器配置文件，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：


3. 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.',
},
4.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
});
……
5.安装PHPword
composer require phpoffice/phpword
6.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"类内容直接复制到自定义WordToHtmlController.class.php文件中
<?php
class 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/20211029/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, $allImg); // 匹配所有的img
if (!$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;
}
}
7.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"//这个地址依据自己系统而定
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：
