Avi*_*Raj 3 node.js google-oauth google-oauth2 actions-on-google dialogflow-es
我正在尝试使用(DialogFlow或API.ai和google操作)开发的我的nodejs Google智能助理应用程序实施oauth2身份验证.
所以我按照这个答案.但我总是得到"看起来你的测试oauth帐户尚未链接."错误.当我尝试打开调试选项卡上显示的URL时,它显示500个损坏的URL错误.

实际上我部署的代码存在于对话框流内联编辑器中.但是不知道如何实现oauth端点,它是应该是一个单独的云功能还是必须包含在存在的功能中.而且我对oauth授权代码流实际如何工作非常困惑.让我们假设我们在Assistant应用程序上,一旦用户说"与foo app交谈",它是否会自动打开web浏览器进行oauth代码交换过程？
您引用的答案在10月25日发布了更新,表明他们已采取措施阻止您作为帐户关联的身份验证提供程序进入google.com端点.他们似乎可能已采取其他措施来阻止以这种方式使用Google的auth服务器.
如果您使用自己的auth服务器,则错误500将指示您的oauth服务器上的错误,您应该检查您的oauth服务器是否有错误.
更新以回答您的其他一些问题.
但是不知道如何实现oauth端点
Google提供有关您需要为最小OAuth服务执行的操作的指导(但不是代码),使用隐式流或授权代码流,以及如何测试它.
它是否应该是一个单独的云功能,或者它必须包含在现有的云功能中
它应该是分开的 - 它甚至可以说它必须是分开的.在隐式流和授权代码流中,您需要提供一个URL端点,用户将被重定向以登录您的服务.对于授权代码流程,您还需要一个辅助用于交换令牌的附加webhook.
这些功能背后的功能需要与您为Dialogflow webhook所做的非常不同.虽然有人可能会创建一个处理所有不同任务的功能 - 但是没有必要.您将单独提供OAuth网址.
但是,您的Dialogflow webhook 确实与您的OAuth服务器有一些关系.特别是,OAuth服务器交给智能助理的令牌将被交还给Dialogflow webhook,因此Dialogflow需要某种方式来获取基于该令牌的用户信息.有很多方法可以做到这一点,但只列出几个:
令牌可以是JWT,并包含用户信息作为正文中的声明.Dialogflow webhook应该使用公钥来验证令牌是否有效,并且需要知道声明的格式.
OAuth服务器和Dialogflow webhook可以使用共享帐户数据库,OAuth服务器将令牌存储为用户帐户的密钥并删除过期的密钥.然后,Dialogflow webhook可以使用它获取的令牌作为查找用户的密钥.
OAuth服务器可能有一个(另一个)webhook,Dialogflow可以在其中请求用户信息,将密钥作为Authorization标头传递并获得回复.(例如,Google就是这样做的.)
确切的解决方案取决于您的需求以及您可以使用的资源.
而且我对oauth授权代码流实际如何工作非常困惑.让我们假设我们在Assistant应用程序上,一旦用户说"与foo app交谈",它是否会自动打开web浏览器进行oauth代码交换过程？
从广义上讲 - 是的.细节有所不同(并且可以改变),但不要过于关注细节.
如果您在扬声器上使用智能助理,系统将提示您打开主应用程序,该应用程序应显示一张卡片,说明行动需要什么权限.单击该卡将打开浏览器或webview到Actions网站以开始流程.
如果您在移动设备上使用智能助理,它会直接提示您,然后打开浏览器或网页浏览到操作网站以开始流程.
认证流程主要涉及:
在幕后,Google会使用此代码,并且由于您使用的是授权代码流,因此需要在令牌交换URL处将其替换为身份验证令牌和刷新令牌.
然后,只要用户使用您的Action,它就会将一个身份验证令牌以及其余请求发送到您的服务器.
Plz建议OAuth2配置的必要包
我不能这样做.对于初学者 - 它完全取决于您的其他资源和要求.(这就是为什么StackOverflow不喜欢人们要求这样的建议.)
有些软件包(您可以搜索它们),可以让您设置OAuth2服务器.我相信那里有人提供OAuth-as-a-service,虽然我不知道任何随便的.最后,如上所述,您可以使用Google的指南编写最小的OAuth2服务器.
试图为Google的OAuth创建一个代理......可能......可能不像最初看起来那么容易 ......可能不像任何人一样安心......并且可能(但不一定是IANAL)a违反了Google的服务条款.
我们不能通过这种方法存储用户的电子邮件地址吗？
那么,您可以在用户的帐户中存储您想要的任何内容.但这是用户对您的操作的帐户.
例如,您可以代表您的用户访问Google API,以获取他们的电子邮件地址或他们授权您与Google合作的其他任何内容.您拥有的用户帐户可能会存储您用于访问Google服务器的OAuth令牌.但是,您应该逻辑地将其视为与Assistant用于访问服务器的代码分开.
