【问题描述】：

在nodejs代码中使用alexa技能中的会话属性

但输出未定义。未定义应该是一种时尚。

。

代码请参考图片

    'expenseIntent': function () {
    var updatedIntent=this.event.request.intent;
    var category1 = this.event.request.intent.slots.category.value;
    var expense;
    if(category1=='fashion'){
        expense = '1000';
    }else if(category1=='travel'){

        expense = '2000';
    }else if(category1=='food'){

        expense = '3000';
    }else {

        expense = '4000';
    }
    this.attributes.lastSpeech = this.event.request.intent.slots.category.value;
    console.log(this.attributes);
    if (this.event.request.dialogState === "STARTED") {
    this.emit(":delegate", updatedIntent);
    }else if(this.event.request.dialogState !== "COMPLETED"){
    this.emit(":delegate", updatedIntent);
    }else {
    console.log("this.event.request.intent.slots.category.value"+this.event.request.intent.slots.category.value);
    this.response.speak("Amount spent on "+category1+" is " + expense);
    this.emit(':responseReady'); 
}
},
'intentTwo': function () {
    var a = this.attributes.lastSpeech;

    //var aa = this.event.request.intent.slots.categories.value;
    this.response.speak("you query was about " + a);
    this.emit(':responseReady');
},

【解决方案1】：

试试这个，

为Session添加属性，

Object.assign(this.attributes, {
    "lastSpeech" = this.event.request.intent.slots.category.value;
});

为了从 Session 中检索它，

var a = this.attributes.lastSpeech;

希望这对您有所帮助。一切顺利:)
