我用来解析JSON的类不允许你在任何字符串中使用冒号。例如，这会导致解析错误：
{
"Test:": "Just a test"
}
关于如何使这个类的任何想法都忽略字符串中的冒号？这是我正在使用的课程：
class JSON {
static var inst;
var text;
function JSON() {
}
static function getInstance() {
if (inst == null) {
inst = new cinqetdemi.JSON();
}
return (inst);
}
static function stringify(arg) {
var _local3;
var _local2;
var _local6;
var _local1 = "";
var _local4;
switch (typeof (arg)) {
case "object" :
if (arg) {
if (arg instanceof Array) {
_local2 = 0;
while (_local2 < arg.length) {
_local4 = stringify(arg[_local2]);
if (_local1) {
_local1 = _local1 + ",";
}
_local1 = _local1 + _local4;
_local2++;
}
return (("[" + _local1) + "]");
} else if (typeof (arg.toString) != "undefined") {
for (_local2 in arg) {
_local4 = arg[_local2];
if ((typeof (_local4) != "undefined") && (typeof (_local4) != "function")) {
_local4 = stringify(_local4);
if (_local1) {
_local1 = _local1 + ",";
}
_local1 = _local1 + ((stringify(_local2) + ":") + _local4);
}
}
return (("{" + _local1) + "}");
}
}
return ("null");
case "number" :
return ((isFinite(arg) ? (String(arg)) : "null"));
case "string" :
_local6 = arg.length;
_local1 = "\"";
_local2 = 0;
while (_local2 < _local6) {
_local3 = arg.charAt(_local2);
if (_local3 >= " ") {
if ((_local3 == "\\") || (_local3 == "\"")) {

_local1 = _local1 + _local3;

查看my answer of this question并使用我在那里提到的JSON课程，它可以正常使用您的测试内容：
import JSON;
var json = new JSON();
var data:String = '{"Test:": "Just a test"}';
trace(json.parse(data)['Test:']); // gives : Just a test
希望可以提供帮助。
