我想用Dialogflow和Google智能助理以及Google Transactions API创建一个聊天机器人,以便用户订购一些商品。现在我的代理包含以下四个意图:
Default Welcome Intent
(文字回复:你好,你想买一个巧克力盒吗?)Default Fallback Intent
Int3
(培训短语:是的,我想要,履行:启用webhook)Int4
(事件:actions_intent_TRANSACTION_DECISION
,履行:已启用webhook)我使用Dialogflow Json而不是Node.js将我的代理与Transactions API连接起来。我想通过使用Google操作的actions.intent.TRANSACTION_DECISION
操作最终使用用户满足交易要求,为用户构建购物车和订单。出于这个原因,在Google文档之后,当Int3
被触发时,我正在使用webhook连接Google Assistant我的后端发送回以下json(触发actions.intent.TRANSACTION_DECISION
):

请注意,我基本上是从Google文档中复制粘贴jsons。
但是,Int4
未触发,这意味着actions.intent.TRANSACTION_DECISION
也未被触发。
我只接受Google智能助理(当Int3
被触发并且上述json作为我的后端的响应发送时)以下消息/错误:
Sorry, something went wrong. Please try again later.
因此,我无法真正理解我的json有什么问题以及为什么actions.intent.TRANSACTION_DECISION
没有被触发。
为什么actions.intent.TRANSACTION_DECISION
未被触发?上面的json有没有未检测到的问题?
我不知道我的问题是否与此有关:Actions on Google returns in simulator "We're sorry, but something went wrong. Please try again."。但是,我从这个链接测试了所有可能的解决方案,到目前为止我没有任何帮助。
此外,请注意,我已经触发了Google Transactions API(actions.intent.TRANSACTION_REQUIREMENTS_CHECK
,actions.intent.DELIVERY_ADDRESS
,actions.intent.SIGN_IN
)的所有其他内置意图,并且它们都能正常运行我的代理/应用。出于某种原因,只有actions.intent.TRANSACTION_DECISION
会将此错误(Sorry, something went wrong. Please try again later.
)返回给我。
答案 0 :(得分:2)
最后我解决了这个问题。它必须在某种意义上与我上面的帖子中的最后一段有关。通过这个,我的意思是它必须与测试这个应用程序所需的一些配置/权限事件有关,而不是我的json等。
但是,我不确切地知道为什么这只发生在actions.intent.TRANSACTION_DECISION
,而与其他Google Transactions API内置意图(actions.intent.TRANSACTION_REQUIREMENTS_CHECK
,actions.intent.DELIVERY_ADDRESS
完全无关, actions.intent.SIGN_IN
)。
具体来说,在Google操作系统中,在我选择了我的项目并登录了我的Google帐户后,我在以下位置填写了所有必需的详细信息:
left sidebar -> DEPLOY -> Directory information -> (Details, Image, Contact Details, Privacy and consent, Additional Information)
完成并保存后,actions.intent.TRANSACTION_DECISION
被按预期触发,我正在获得预期的&#34;购物车预览&#34;在Google智能助理上(在手机上)。
