    FastAdmin 的上传代码在哪里?

    FastAdmin 默认是通过 Ajax 上传到本地。

    使用 admin/ajax/upload 方式返回 url。

    代码文件地址在 applicationadmincontrollerAjax.php 中。

        public function upload()
        {
            Config::set('default_return_type', 'json');
            $file = $this->request->file('file');
            if (empty($file)) {
                $this->error(__('No file upload or server upload limit exceeded'));
            }
    
            //判断是否已经存在附件
            $sha1 = $file->hash();
    
            $upload = Config::get('upload');
    
            preg_match('/(d+)(w+)/', $upload['maxsize'], $matches);
            $type = strtolower($matches[2]);
            $typeDict = ['b' => 0, 'k' => 1, 'kb' => 1, 'm' => 2, 'mb' => 2, 'gb' => 3, 'g' => 3];
            $size = (int)$upload['maxsize'] * pow(1024, isset($typeDict[$type]) ? $typeDict[$type] : 0);
            $fileInfo = $file->getInfo();
            $suffix = strtolower(pathinfo($fileInfo['name'], PATHINFO_EXTENSION));
            $suffix = $suffix ? $suffix : 'file';
    
            $mimetypeArr = explode(',', strtolower($upload['mimetype']));
