如何将JSON转换为node.js对象

Question

I have a JSON tree like this that is being posted to my node.js (we'll call it message for the sake of this question):

var message = ["layer1": [
                     "color": "Blue",
                     "size": "small",
                     "layer2": [
                         "item1": "TEST"
                     ]
                  ]
              ]

How can I make it so I can access individual nodes and values in node.js, something like this:

var sample1 = message.layer1
var sample2 = message.layer1.layer2.item1

if I were to console.log(sample1) it would look like this:

["color": "Blue",
 "size": "small",
 "layer2": [
     "item1": "TEST"
     ]
]

and console.log(sample2) would look like this:

"TEST"

Is this possible?

Answer 1

The syntax of your message variable is not Javascript (your message seems to be an array, but have key:value , which is not allowed in Javascript).

You have to replace " [ " by " { " and " ] " by " } " in your message to have a Javascript object. Then your sample1 and sample2 variables should work.
