Laravel中使用wangEditor

wangEditor是一个优秀的国产的轻量级富文本编辑器(虽然本人还是喜欢MarkDown，但是不是任何人都喜欢MarkDown这样的编写方式的)，wangEditor和百度的UEditor相比，确实是要轻量很多，UEditor太过于臃肿而且编辑用起来很难做到格式的一个统一性。
本人现在在使用laravel-admin这个后台的框架，感觉用起来还比较轻量级，中文文档充足。

创建一个Field的扩展
<?php
namespace App\Admin\Extensions;
use Encore\Admin\Form\Field;
class WangEditor extends Field
{
protected $view = 'admin.wangeditor';
protected static $css = [
'/packages/admin/wangEditor/dist/css/wangEditor.min.css',
];
protected static $js = [
'/packages/admin/wangEditor/dist/js/wangEditor.js',
];
public function render()
{
$editor_id = $this->id;
$z_index = 999999;
$printLog = config('wang-editor.printLog', 'true');
$uploadImgUrl = config('wang-editor.uploadImgUrl', '/admin/upload/uploadImg');
$mapAk = config('wang-editor.mapAk', 'TVhjYjq1ICT2qqL5LdS8mwas');
$pasteFilter = config('wang-editor.pasteFilter', 'false');
$pasteText = 'true';
if ($pasteFilter == 'true') {
$pasteText = config('wang-editor.pasteText', 'true');
}
$token = csrf_token();
$this->script = <<<EOT
var menus = [
'source',
'|',
'bold',
'underline',
'italic',
'strikethrough',
'eraser',
'forecolor',
'bgcolor',
'|',
'quote',
'fontfamily',
'fontsize',
'head',
'unorderlist',
'orderlist',
'alignleft',
'aligncenter',
'alignright',
'|',
'link',
'unlink',
'table',
'emotion',
'|',
'img',
'video',
// 'location',
'insertcode',
'|',
'undo',
'redo',
'fullscreen'
];
wangEditor.config.printLog = {$printLog};
var _{$editor_id} = new wangEditor('{$editor_id}');
_{$editor_id}.config.uploadImgUrl = "{$uploadImgUrl}";
_{$editor_id}.config.uploadParams = {
token : '{$token}'
};
_{$editor_id}.config.mapAk = '{$mapAk}';
_{$editor_id}.config.zindex = {$z_index};
var _pasteFilter = {$pasteFilter};
_{$editor_id}.config.pasteFilter = _pasteFilter;
if (_pasteFilter == true) {
_{$editor_id}.config.pasteText = {$pasteText};
}
_{$editor_id}.config.uploadImgFileName = 'wang-editor-image-file';
_{$editor_id}.create();
EOT;
return parent::render();
}
}
创建对应的blade view
<div class="form-group {!! !$errors->has($errorKey) ?: 'has-error' !!}">
<label for="{{$id}}" class="col-sm-2 control-label">{{$label}}</label>
<div class="col-sm-6">
@include('admin::form.error')
<textarea style="height:400px;max-height:500px;display: none" cols="5" class="form-control" id="{{$id}}" name="{{$name}}" placeholder="{{ $placeholder }}" {!! $attributes !!} >{{ old($column, $value) }}</textarea>
@include('admin::form.help-block')
</div>
</div>
bootstrap.php中注册扩展
Form::extend('wangeditor', WangEditor::class);
调用这个wangeditor扩展

这个时候基本你就可以使用wangeditor编辑器，但是无法上传图片
public function postUploadPicture(Request $request)
{
if ($request->hasFile('wang-editor-image-file')) {
//
$file = $request->file('wang-editor-image-file');
$data = $request->all();
$rules = [
'wang-editor-image-file' => 'max:5120',
];
$messages = [
'wang-editor-image-file.max' => '文件过大,文件大小不得超出5MB',
];
$validator = Validator($data, $rules, $messages);
// $validator = $this->validate($data, $rules, $messages);
$res = 'error|失败原因为：非法传参';
if ($validator->passes()) {
$realPath = $file->getRealPath();
$destPath = 'uploads/content/';
$savePath = $destPath.''.date('Ymd', time());
is_dir($savePath) || mkdir($savePath); //如果不存在则创建目录
$name = $file->getClientOriginalName();
$ext = $file->getClientOriginalExtension();
$check_ext = in_array($ext, ['gif', 'jpg', 'jpeg', 'png'], true);
if ($check_ext) {
$uniqid = uniqid().'_'.date('s');
$oFile = $uniqid.'o.'.$ext;
$fullfilename = '/'.$savePath.'/'.$oFile; //原始完整路径
if ($file->isValid()) {
$uploadSuccess = $file->move($savePath, $oFile); //移动文件
$oFilePath = $savePath.'/'.$oFile;
$res = $fullfilename;
} else {
$res = 'error|失败原因为：文件校验失败';
}
} else {
$res = 'error|失败原因为：文件类型不允许,请上传常规的图片(gif、jpg、jpeg与png)文件';
}
} else {
$res = 'error|'.$validator->messages()->first();
}
}
return $res;
}
路由注册一下和扩展中配置的路径统一就可以使用上传图片了，不使用Laravel-admin框架的可以直接使用wangEditor：直接看这里

后续使用后的更新
使用上面的上传图片感觉非常的不爽，图片处理太弱了，都无法压缩、水印、调整大小等等
推荐使用image.intervention处理图片
