要使此Bike Shop示例的修改版本（或相应的原始版本）起作用，我遇到了一些严重困难。
我试图复制基本功能，但将名称，电话号码，电子邮件等字段添加到日历事件中。
也许是因为这是我第一次使用Node.js，但是事实证明，这不如在热水泥中沐浴。
我将快速总结一下我遇到的主要问题：
获取要在日历中填充的事件
因此，感谢@Prisoner，我几乎可以解决所有问题。我的主要问题是我的上下文是大写的，因此未被认可。将大多数意图转换为顶层也有帮助。现在，我可以始终如一地得到履行答复，并给我我的第一条确认消息，但是我总是得到我的第二次“错误”答复，并且日历中没有任何事件。
未显示在日历上 如何更新googleapis库？只需将package.json中的^ 27更改为^ 30？
上下文
.getContext()是否已过时？这就是它在这里（https://dialogflow.com/docs/contexts/contexts-fulfillment）所说的，这就是我昨天尝试时出现的错误。
带有连字符的实体
我更改了名称（我不知道名称不只是一个标签），但是为了将来参考和清楚起见，是.parameters，.properties还是.params？
仅供参考，这是我的Intent流程： Scheduleappointment>
FirstLast（获取名字和姓氏，分配给系统实体）>
ServiceNeeded（获取所需的服务，分配给开发者实体）>
Date Time MeetingPlace电子邮件电话N（获取日期，时间，电话号码和电子邮件：分配给系统实体；获取位置：分配给开发者实体）

答案 0 :(得分：1)
很多问题，让我们来看看我们可以解决的问题。
无法读取属性“拆分”
第192行是
return new Date(Date.parse(date.split('T')[0] + 'T' + time.split('T')[1].split('-')[0] + '-' + time.split('T')[1].split('-')[1]));
，它有许多对split()的调用，因此尚不清楚是哪个引起了问题，但这是因为date或time（或两者）都没有尚未定义。
包含两个行的convertTimestampToDate()函数是从两个不同的地方调用的。您的makeAppointment()和checkAppointment()函数似乎都在同一行
const dateTimeStart = convertTimestampToDate(agent.parameters.date, agent.parameters.time);
您自己没有显示Schedule appointment - Date Time meetingPlace或Schedule appointment - Date Time meetingPlace - yes Intent配置，但听起来其中一个实际上没有date或time参数。
对实现的回应
您对于未生成响应的状态有点不确定，但是对于具有处理程序的两个Intent，响应似乎已正确设置。
在以下任何情况下，都将使用UI中的内容：
每封邮件最多只能有640个字符，但我认为您的答复没有达到这个限制，我想在某些情况下可能会做到这一点。
动态参数未定义
我不确定您所说的“动态”是什么意思，但这听起来像是date和time未定义的问题。再次，我将检查以确保在您认为是的Intent中发送了这些参数。
从Intent的“流”（我将在下面讨论），听起来像您期望参数从Intent到Intent一样不断填充。通常，参数是从 current Intent提供的。
如果设置了“输出上下文”，则还可以在上下文中设置参数，这些参数将继承到将来的Intent。因此，您可能希望从上下文而不是参数中获取它们。
根据以下sid的注释进行更新：如果您想要希望当前Intent参数中的过去参数，则需要使用一些内容从上下文中显式设置Intent中的值类似于Intent参数部分的#output-context.param。
未显示在日历上
您使用的是googleapis库的相当老的版本，这可能是问题也可能不是问题。但是，较新的版本本身支持Promises，这肯定会使您的代码更易于使用。
我不是很确定，但是您要指定一个名为resource的属性，该属性包含事件资源（根据specification），并且应位于请求的正文中。我不知道您正在使用的库是否对此进行了更改，但是在current library中，此字段应称为requestBody。
上下文
处理上下文的最佳方法是使用直接访问器方法，例如agent.getContext()，agent.setContext()和agent.clearContext()。
您可能已经在Google上看到了一些有关Actions的较旧的文档，其中涉及conv.contexts，但在这种情况下不适用。
带有连字符的实体
最简单的方法是将Intent UI中的参数名称更改为不带连字符的名称。您可以随心所欲地调用它们-无需在实体类型之后命名它们。
如果您确实想保留连字符，请针对agent.properties对象对它们进行索引（这似乎是您这样做的方式）。所以
agent.properties['what-ever']
意图流
您没有显示Intent配置，但这听起来像是一系列后续意图中的这些问题。
这...并不总是一个好主意。对话并不总是线性的，用户可能会尝试在对话中向后（或向前）前进，而“后续意图”则无法很好地处理。
一个更好的解决方案是将大多数这些Intent作为顶层，所有这些都使用实现。 Intent负责将参数传递给实现，将其存储起来，然后确定仍然缺少的值并要求一个。如果您认为需要缩小对用户的期望，可以考虑使用Context，但这并不是您想的那样必要。 （有关此问题的讨论，请参见Thinking for Voice: Design Conversations not Logic。）
