Question

当其他快速通话正常工作时，我无法从dialogflow获取响应。

我知道这是代理商的问题，但是我不确定这个问题是什么或如何解决，这就是为什么我要在这里询问。

要注意的重点。

此代码已添加到现有的经过测试的Express应用程序中
使用postman
对话框流填充模板Webhook可以找到here
控制台成功输出We got hours!，然后不再继续
如果您注释行57 through 62 (the if section)和取消注释行56的代码会按预期方式响应
该问题应该在agents.hours函数之内
也尝试过this.currentlyOpen() === true

非常感谢。

编辑：更新了代码以匹配注释。在出现问题的地方添加注释。

问题在于，this不是您想像的（或想要的），这是由于hours()的调用方式以及this的含义不同所致叫做。 This page详细介绍了详细内容，但总之（适用于您）：

被调用的函数已将this应用于全局对象，而不是应用于this的词法绑定版本（即-this的值在班级内
要获取this的词法绑定版本，您需要使用bind()将值绑定到函数，或使用箭头函数进行调用。

在您的情况下，这意味着您应该使用类似的方法注册Intent处理程序

intentMap.set('Hours', agent => this.hours(agent));
