我正在通過拉拉維爾的郵遞員提交數(shù)據(jù)。如果在提交期間未插入數(shù)據(jù)，我需要顯示空值（在JSON響應(yīng)中）。但它沒有顯示圖像響應(yīng)我需要顯示圖像響應(yīng)也為空我的商店代碼是public function store(Request $request){    $screenshots  = new Screenshots ;    $screenshots->user_id = $request->user_id;    $screenshots->name = $request->name;    $screenshots->size = $request->size;    if($request->hasFile('image')){        $fileNameExt = $request->file('image')->getClientOriginalName();        $fileName = pathinfo($fileNameExt, PATHINFO_FILENAME);        $fileExt = $request->file('image')->getClientOriginalExtension();        $fileNameToStore = $fileName.'.'.$fileExt;        $pathToStore = $request->image->storeAs('public/uploads/screenshots', $request->image->getClientOriginalName());        $screenshots->image = $fileNameToStore;         $screenshots->save();    };    $screenshots->save();    return $this->sendResponse($screenshots->toArray(), 'Command Send Successfully successfully.');}當(dāng)任何字段為空時(shí)，它給出一個(gè)空值，但如果圖像為空，我沒有任何響應(yīng)。更清晰，請(qǐng)參閱隨附的屏幕截圖獲得響應(yīng) 就像{"success":true,"data":{"user_id":"2","name":null,"size":"3.4kb","updated_at":"2020-02-12 07:26:49","created_at":"2020-02-12 07:26:49","id":32},"message":"Command Send Successfully successfully."}如果圖像也是空白的，我需要的響應(yīng){"success":true,"data":{"user_id":"2","name":null,"size":"3.4kb","image":"null","updated_at":"2020-02-12 07:26:49","created_at":"2020-02-12 07:26:49","id":32},"message":"Command Send Successfully successfully."}
