如何应对JSONP中的无效标签错误？

Question

我的json网址是：http://app.websitename.in/getToken。

上面的网址返回我以下JSON：

 { "token": "2cd3e37b-5d61-4070-96d5-3dfce0d0acd9%a00a5e34-b017-4899-8171-299781c48c72" }

调用以下代码时，我（仍然）收到无效标签错误。

我的代码是：

 $.getJSON("http://app.websitename.in/getToken?callback=?", 
function(data) {
alert("success");
    alert("Symbol: " + data.token);
});

请帮帮我，多谢！

Property names must be in double quotes to be valid JSON, e.g.:

{ token: "2cd3e37b-5d61-4070-96d5-3dfce0d0acd9%a00a5e34-b017-4899-8171-299781c48c72" }

must be

{ "token": "2cd3e37b-5d61-4070-96d5-3dfce0d0acd9%a00a5e34-b017-4899-8171-299781c48c72" }

(Note that "token" is now in double quotes.)

Details on the JSON site. JSONlint is also helpful.

Some JSON parsers are lax and let you get away with not putting double quotes around property names (particularly ones that are really JavaScript parsers in disguise), but technically, it's required.
