javascript - Rhino JSON.stringify 未定义

Question

我正在尝试使用来自 maven 的 Rhino 1.7.7.1 从我的 javascript 打印一个简单的 JSON。

public static void main(String[] args) throws JsonProcessingException {
    Context context = Context.enter();
    try {
        ScriptableObject scope = context.initStandardObjects();
        System.out.println(context.evaluateString(scope, "JSON.stringify({a:1})", null, 1, null));
    } finally {
        Context.exit();
    }
}

但是我有:

Exception in thread "main" org.mozilla.javascript.EcmaError: ReferenceError: "JSON" is not defined. (unnamed script#1)
    at org.mozilla.javascript.ScriptRuntime.constructError(ScriptRuntime.java:3654)

JSON.stringify 未在 Rhino 1.7 引擎中实现。查看Rhino compatibility table .
