我想在 Laravel 5.1 中解码画廊数组 JSON 对象。我的 JSON 是：
{
"title": "aaaaaaaaaaaaaaaa",
"category_id": "1",
"user_id": "1",
"gallery": "[{name: \"XCB808tvXNpqXKqekA2HlkJ8H.jpg\",size:5112},{name: \"s6kA6B0e5m1sdSAjPXqNwtiy4.jpg\", size: 13135}]"

当我使用此代码时，请返回null：
public function store(Request $request)
{
$json = json_decode($request['gallery'],true);
return $json;
}
}
and this is dd($request['gallery'])result
这是dd($request['gallery'])结果
[{'name': "XCB808tvXNpqXKqekA2HlkJ8H.jpg",'size':5112},{'name': "s6kA6B0e5m1sdSAjPXqNwtiy4.jpg", 'size': 13135}]

The decoding process is right. I think your problem is you could have a malformed JSON string.
解码过程是正确的。我认为你的问题是你可能有一个格式错误的 JSON 字符串。
Replace the single quotes around property names with double quotes:
用双引号替换属性名称周围的单引号：
[{"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,
我不太确定您的程序流程，但是当您将请求依赖项注入到 store 函数时，我假设 JSON 对象是您请求的一部分。在这种情况下，你可以尝试，
$input = $request->json()->all();
Just print_r($input) and see what you are getting.
只需 print_r($input) 看看你得到了什么。
If JSON object is not a part of your request, you missed passing $json to your function. This is a wild guess, though!
如果 JSON 对象不是您的请求的一部分，您就没有将 $json 传递给您的函数。不过，这是一个疯狂的猜测！
