基于以下内容,我如何设置回调以显示自定义错误消息而不是默认消息？

ko.validation.rules['exampleAsync'] = {
    async: true, // the flag that says "Hey I'm Async!"
    validator: function (val, otherVal, callBack) { // yes, you get a 'callback'

        /* some logic here */

        // hand my result back to the callback
        callback( /* true or false */ );
        // or if you want to specify a specific message
        callback( /* { isValid: true, message: "Lorem Ipsum" } */ );
    },
    message: 'My default invalid message'
};
