如何从Laravel5中的json类型响应中获取值

Question

Here is a function return:

return response()->json(['aa'=>'bbb']);  

and i print the function response ,the result like this:

JsonResponse {#186
 #jsonOptions: 0
 #data: "{"aa":"bbb"}"
 #callback: null
 #encodingOptions: 15
 +headers: ResponseHeaderBag {#187
 #computedCacheControl: array:1 [
  "no-cache" => true
]

i have never seen it before,how can i get the value bbb ? thanks

Answer 1

i have resolved the question,use getData() can read the json.

$a = response()->json(['aa'=>'bbb']);  
$a->getData()->aa;
