ThinkPHP6.0上传文件，官方说了：内置的上传只是上传到本地服务器，上传到远程或者第三方平台的话需要安装额外的扩展。
本案例是上传到本地服务器，需要远程上传到第三方平台需要安装额外的扩展，以下是控制器中直接对文件处理，使用了Db类库，在数据表中存储了记录，功能待自行扩展，勿怪。
而且测试上传使用的是Kindeditor编辑器上传，可上传图片，视频，flash，文件，简单处理了图片按钮只能上传图片，视频类似，flash类似，文件类似。请参考：https://www.kancloud.cn/manual/thinkphp6_0/1037639

$file = request()->file('imgFile');//根据表单name替换imgFile
try {
$dir_name = request()->param('dir');//kindeditor上传 获取上传类型
//分类定义允许上传的文件
$ext_arr = array(
'image' => array('gif','jpg','jpeg','png','bmp'),

静态模板代码，引入了Kindeditor编辑器js等文件，初始化了编辑器，只要引入文件上面代码可以直接使用。
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<title>Default Examples</title>
<style>
form {
margin: 0;
}
textarea {
display: block;
}
</style>
<link rel="stylesheet" href="__STATIC__/kindeditor/themes/default/default.css" />
<script charset="utf-8" src="__STATIC__/kindeditor/kindeditor-all.js"></script>
<script charset="utf-8" src="__STATIC__/kindeditor/lang/zh-CN.js"></script>
<script>
var editor;
KindEditor.ready(function(K) {
editor = K.create('textarea[name="content"]', {
allowFileUpload : true,
allowFileManager : true,
allowFlashUpload : true,
uploadJson : '{:url('attachment/upload')}',
});
});
</script>
</head>
<body>
<h3>默认模式</h3>
<form>
<textarea name="content" style="width:800px;height:400px;visibility:hidden;">KindEditor</textarea>
</form>
</body>
</html>
注意事项（模板变量配置位置：/vendor/topthink/think-template/src/Template.php中查找变量自行配置），需隐藏入口文件index.php（单模块）：
'tpl_replace_string' => [
'__THEMES__'=>'/static/frontend/theme',
'__STATIC__'=>'/static',
'__JS__' => '/static/javascript',
],
