我们同时上传的还有昵称，图片是保存在resource表里面，，

对应在userProfile有关联id;利用laravel自带上传很方便，，

但是不能直接访问，，所以需要建立软链接：

PHP artisan storage:link

执行该条命令会在public里面生成存储图片的文件夹，就可以通过地址访问了

public function uploadAvatar(Request $request)
{
 $validator = Validator::make($request->all(), [
  'nickname' => 'required|string|max:8',
  'avatar' => 'required',
 ]);
 if ($validator->fails()) {
  return $this->responseForJson(ERR_ACCESS_DENID, $validator->errors());
 }
 $user_id=Auth::id();
 $avatar = $request->file('avatar')->store('/public/'.date('Y-m-d').'/avatars');
 $avatar = Storage::url($avatar);
 
 $resource=Resource::insertGetId(['type'=>1,'resource'=>$avatar]);
 $Data=['user_id'=>$user_id,'avatar'=>$resource,'nickname'=>$request->nickname];
 try {
  $edit = UserProfile::where('user_id',$user_id)->update($Data);
  if ($edit) {
   return $this->responseForJson(ERR_OK, 'upload success');
  }
  return $this->responseForJson(ERR_CREATE, 'upload fail');
 }catch (\Exception $exception) {
  return $this->responseForJson(ERR_ACCESS_DENID, $exception->getMessage());
 }
}
