cmf的远程抓取图片是不能用的
所以需要我们自己去改改。
/**
* 获取远程图片
*/
private function _get_remote_image()
{
// $source = $this->request->param()['source'];

$allowedExts = explode(',', $uploadSetting['file_types']["image"]["extensions"]);
$strSavePath = ROOT_PATH . 'public' . DS . "ueditor" . DS . $date . DS;
//远程抓取图片配置
$config = [

];

$list = [];

//后来的修改者:这里默认走if,不存在的时候走下面,其实最好的方法是直接写else里面的,if是原作者的思路,不知道什么意思,else里面的为我的思路

//打开输出缓冲区并获取远程图片

//创建保存位置
if (!file_exists($savePath)) {
mkdir("$savePath", 0777, true);
}
$file_write_result = cmf_file_write($tmpName, $img);

//todo qiniu code
}elseif(config('FILE_UPLOAD_TYPE') == 'Local') {

} else {

array_push($list, $return_img);
}
}
return json_encode([
'state' => count($list) ? 'SUCCESS' : 'ERROR',
'list' => $list
]);
}
另外,这里使用还有两个点需要注意:
如果发现这个方法不存在:cmf_file_write 请自己新建一个方法。
请在配置里面加上
'FILE_UPLOAD_TYPE' => 'Local'
