如何在 laravel 中將名稱設(shè)置為 JSON 對(duì)象，因?yàn)槲蚁朐?Vue js 中為圖片庫(kù)顯示插件。每當(dāng)我傳遞數(shù)據(jù)時(shí)，我都會(huì)收到此錯(cuò)誤：預(yù)期對(duì)象，得到數(shù)組。{ "normal_size": [ { "id": 1, "image": "MICMIMC30651-6.jpg", "url": "http://localhost:8000/images/product/preview/MICMIMC30651-6.jpg" }, { "id": 2, "image": "MICMIMC30651-61.jpg", "url": "http://localhost:8000/images/product/preview/MICMIMC30651-61.jpg" }, { "id": 3, "image": "MICMIMC30651-62.jpg", "url": "http://localhost:8000/images/product/preview/MICMIMC30651-62.jpg" }, { "id": 4, "image": "MICMIMC30651-63.jpg", "url": "http://localhost:8000/images/product/preview/MICMIMC30651-63.jpg" } ]}我想要的輸出： image : { "normal_size": [ { "id": 1, "image": "MICMIMC30651-6.jpg", "url": "http://localhost:8000/images/product/preview/MICMIMC30651-6.jpg" }, { "id": 2, "image": "MICMIMC30651-61.jpg", "url": "http://localhost:8000/images/product/preview/MICMIMC30651-61.jpg" }, { "id": 3, "image": "MICMIMC30651-62.jpg", "url": "http://localhost:8000/images/product/preview/MICMIMC30651-62.jpg" }, { "id": 4, "image": "MICMIMC30651-63.jpg", "url": "http://localhost:8000/images/product/preview/MICMIMC30651-63.jpg" } ]}`Laravel 產(chǎn)品控制器代碼將數(shù)據(jù)傳遞給 vue 組件 $normal_size = DB::table('products_images')->where([['products_id', '=', $product]]) ->select('products_images.id','products_images.image') ->get()->ToArray();foreach($normal_size as $value) { $value->url = 'http://localhost:8000/images/product/preview/'.$value->image; }$output = (array('normal_size' => $normal_size));return response()->json(($output));

解決方案：
只需在發(fā)送前調(diào)整輸出格式。
$output= ['image' => json_decode($data)];
或者
$output= array("image" => json_decode($data));
函數(shù)式編程

解碼您的 JSON 以轉(zhuǎn)換數(shù)組。格式化所需的數(shù)組結(jié)構(gòu)并將數(shù)組編碼為 JSON。
$data = '{
"normal_size": [
{
"id": 1,
"image": "MICMIMC30651-6.jpg",
"url": "http://localhost:8000/images/product/preview/MICMIMC30651-6.jpg"
},
{
"id": 2,
"image": "MICMIMC30651-61.jpg",
"url": "http://localhost:8000/images/product/preview/MICMIMC30651-61.jpg"
},
{
"id": 3,
"image": "MICMIMC30651-62.jpg",
"url": "http://localhost:8000/images/product/preview/MICMIMC30651-62.jpg"
},
{
"id": 4,
"image": "MICMIMC30651-63.jpg",
"url": "http://localhost:8000/images/product/preview/MICMIMC30651-63.jpg"
}
]
}';
$output = json_encode(['image' => json_decode($data, true)]);
echo $output;
工作演示。
