推荐答案

首先，你需要去$ C C的JSON $的，可能使用的的as3corelib ：

First of all you need to decode the JSON, probably using as3corelib:

var jsonString:String = '{"srcLocation":"pc","filename":"name","fileext":"jpg","url":""}';
var decodedObj:Object = JSON.decode(jsonString);

然后，所有你需要做的是通过对象循环，让所有的名称/值对：

Then all you have to do is loop through the object to get all the name/value pairs:

for(var key:String in decodedObj) {
    trace("Name: " + key + " - Value: " + decodedObj[key];
}

将输出：

Name: srcLocation - Value: pc
Name: filename - Value: name
Name: fileext - Value: jpg
Name: url - Value:
