java - 不能使用 enumerateLoadedClasses

问题描述

我成功启动了 frida 服务器（使用 su）并将其附加到进程中而没有错误。Java.Interceptor工作正常，但我无法枚举类，我只是得到Unexpected end of block错误。

Java.perform(() => {
    Java.enumerateLoadedClasses({
        "onMatch": function(name) {
            console.log(name);
        },
        "onComplete": function() {
            console.log('Done!');
        }
    });
});

然后：
