SiteFactory支援pdf一鍵上傳
當前功能基於PHP，其它語言流程大抵相同。
大概流程：
1. 將docx檔案上傳到伺服器中
2. 使用PHPoffice/PHPword實現將word轉換為HTML
3. 將HTML程式碼返回並賦值到編輯器中
1 編輯器配置修改
1.1 新增上傳word json配置
在ueditor\php\config.json中新增如下配置：
/* 上傳word配置 */
"wordActionName": "wordupload", /* 執行上傳視訊的action名稱 */
"wordFieldName": "upfile", /* 提交的視訊表單名稱 */
"wordPathFormat": "/public/uploads/word/{yyyy}{mm}{dd}/{time}{rand:6}", /* 上傳儲存路徑,可以自定義儲存路徑和檔名格式 */
"wordMaxSize": 102400000, /* 上傳大小限制，單位B，預設100MB */
"wordAllowFiles": [".docx"] /* 僅支援docx格式的word */
1.2 修改編輯器配置檔案
1.2.1 在工具欄上新增按鈕
在ueditor\ueditor.config.js檔案中，新增按鈕名稱"wordupload"，並新增滑鼠懸浮提示，如下所示：
//工具欄上的所有的功能按鈕和下拉框，可以在new編輯器的例項時選擇自己需要的重新定義
, 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'
]]
//當滑鼠放在工具欄上時顯示的tooltip提示,留空支援自動多語言配置，否則以配置值為準
,labelMap:{
'wordupload': '上傳word檔案',
}
在ueditor\themes\default\images\目錄下新增按鈕圖示"word_upload.png"：
在ueditor\themes\default\css\ueditor.css檔案中新增按鈕樣式：
.edui-for-wordupload .edui-icon {
width: 16px;
height: 16px;
background: url(../images/word_upload.png) no-repeat 2px 2px !important;
}
最後在ueditor\ueditor.all.js檔案中editorui["simpleupload"] = function (editor){}後面新增如下程式碼：
/* word上傳 */
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;
};
1.2.2 新增語言配置
在ueditor\lang\zh-cn\zh-cn.js檔案中在"simpleupload"配置下方新增以下配置：
'simpleupload':{
'exceedSizeError': '檔案大小超出限制',
'exceedTypeError': '檔案格式不允許',
'jsonEncodeError': '伺服器返回格式錯誤',
'loading':"正在上傳...",
'loadError':"上傳錯誤",
'errorLoadConfig': '後端配置項沒有正常載入，上傳外掛不能正常使用！'
},
'wordupload':{
'exceedSizeError': '檔案大小超出限制',
'exceedTypeError': '檔案格式不允許',
'jsonEncodeError': '伺服器返回格式錯誤',
'loading':"正在上傳...",
'loadError':"上傳錯誤",
'errorLoadConfig': '後端配置項沒有正常載入，上傳外掛不能正常使用！'
},
在ueditor\lang\zh-cn\en.js檔案中在"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 修改過濾配置
由於匯入word時，編輯器會自動過濾掉圖片等樣式，所以需取消過濾
在ueditor\ueditor.config.js檔案中修改如下配置：
// xss 過濾是否開啟,inserthtml等操作
,xssFilterRules: false
//input xss過濾
,inputXssFilter: false
//output xss過濾
,outputXssFilter: false
在ueditor\ueditor.all.js檔案中，修改UE.plugins[‘defaultfilter’]，新增return ;如下所示：
// plugins/defaultfilter.js
///import core
///plugin 編輯器預設的過濾轉換機制
UE.plugins['defaultfilter'] = function () {
return;
var me = this;
me.setOpt({
'allowDivTransToP':true,
'disabledTableInTable':true
});
……
2 新增相關功能
2.1 安裝PHPword
composer require phpoffice/phpword
1
2.2 自定義檔案轉換類
實現上傳檔案，並將檔案轉換為HTML
直接將ueditor自帶的上傳檔案"ueditor\php\Uploader.class.php"類複製到自定義類相同目錄下
自定義WordToHtmlController.class.php檔案：
<?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);
// 直接輸出到頁面顯示
// $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());
}
/**
* 將HTML程式碼中的所有圖片地址替換
* @param $content string 要查詢的內容
* @return string
*/
private function replaceImageSrc($content)
{
$preg = '/(\s+src\s?\=)\s?[\'|"]([^\'|"]*)/is'; // 匹配img標籤的正則表示式
preg_match_all($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]; // 獲取型別
// 判斷目錄是否存在，不存在時建立
$tempFilePath = 'public/uploads/word_images/' . date('Y-m-d', time());
if (!file_exists($tempFilePath))
mkdir($tempFilePath);
// 拼接完整路徑
$tempFileName = $tempFilePath . '/word_image_' . time() . $k . '.' . $tempType;
$base64 = str_replace($temp[1], '', $old);
file_put_contents($tempFileName, base64_decode($base64));
// 替換路徑字串
$content = str_replace($old, $tempFileName, $content);
}
return $content;
}
}
2.3 編輯器實現匯入操作
在ueditor\ueditor.all.js檔案中UE.plugin.register('simpleupload', function (){})下方新增如下方法：
/**
* @description
* word上傳:點選按鈕,直接選擇檔案上傳
*/
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{
// 獲取到內容
var body = (iframe.contentDocument || iframe.contentWindow.document).body;
// 獲取載入中圖片並關閉
var loader = me.document.getElementById(loadingId);
loader.removeAttribute('id');
domUtils.removeClasses(loader, 'loadingclass');
// 向編輯器賦值
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
});
}
}
/* 判斷後端配置是否沒有載入成功 */
if (!me.getOpt('wordActionName')) {
errorHandler(me.getLang('autoupload.errorLoadConfig'));
return;
}
// 判斷檔案格式是否錯誤
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);
// 上傳操作
// form.action = utils.formatUrl(imageActionUrl + (imageActionUrl.indexOf('?') == -1 ? '?':'&') + params);
// 替換請求地址為框架後臺地址
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() {
//設定loading的樣式
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上傳按鈕 */
'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;
}
}
}
}
});
然後在同文件下的btnCmds變數中新增上自定義的按鈕：
//為工具欄新增按鈕，以下都是統一的按鈕觸發命令，所以寫在一起
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，結果示意圖：
