如何在 Laravel 中解码 JSON 对象

Question

I want to decode gallery array JSON objects in Laravel 5.1. my JSON is:

{
  "title": "aaaaaaaaaaaaaaaa",
  "category_id": "1",
  "user_id": "1",
  "gallery": "[{name: \"XCB808tvXNpqXKqekA2HlkJ8H.jpg\",size:5112},{name: \"s6kA6B0e5m1sdSAjPXqNwtiy4.jpg\", size: 13135}]"
}

When I use this code, return me null :

public function store(Request $request)
    {
         $json = json_decode($request['gallery'],true);
         return $json;
    }
}

and this is dd($request['gallery']) result

[{'name': "XCB808tvXNpqXKqekA2HlkJ8H.jpg",'size':5112},{'name': "s6kA6B0e5m1sdSAjPXqNwtiy4.jpg", 'size': 13135}]

Answer 1

The decoding process is right. I think your problem is you could have a malformed JSON string.

Replace the single quotes around property names with double quotes:

[{"name": "XCB808tvXNpqXKqekA2HlkJ8H.jpg","size":5112},{"name": "s6kA6B0e5m1sdSAjPXqNwtiy4.jpg", "size": 13135}]

I am not pretty sure about your program flow but as you are injecting Request dependency to the store function, I assume the JSON object is a part of your request. In that case, you can try,

$input   = $request->json()->all();

Just print_r($input) and see what you are getting.

If JSON object is not a part of your request, you missed passing $json to your function. This is a wild guess, though!

你可以使用 Response::json($value);

Just dropping by for having the same issue of trying to get the json formatted response (Laravel 8.8.0). The way I was able to get it working was using:

$jsonFormattedResult = json_decode ($response->content(), true);

Hope it helps someone out. ( '-')/
