JsonResponse {#186
 #jsonOptions: 0
 #data: "{"aa":"bbb"}"
 #callback: null
 #encodingOptions: 15
 +headers: ResponseHeaderBag {#187

  "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;

Answer 2

What you see is the object that response()->json() produces. That's not actually what the client will get. Because Laravel will convert it into a string before sending it back.

On the client you can just use it as JSON. Here's an example with jQuery ajax:

$.ajax({
    url: '/your/route'
}).done(function(data){
    alert(data.aa);  // alerts bbb
});
