与Google Assistant关联的帐户未在请求中获得accessToken

问题描述

我已经在Google操作中实现了帐户关联。我选择了具有隐式链接类型的OAuth。我已链接我的帐户，但在后续通话中没有访问令牌。在google文档中说：“在Google获得您的服务访问令牌后，Google会将该令牌附加到随后对您的Action的调用中，作为AppRequest的一部分。”请求中的用户信息应采用以下格式：

{
user : {
  "idToken": string,"profile": {
    object (UserProfile)
  },"accesstoken": string,"permissions": [
    enum (Permission)
  ],"locale": string,"lastSeen": string,"userStorage": string,"packageEntitlements": [
    {
      object (PackageEntitlement)
    }
  ],"userVerificationStatus": enum (UserVerificationStatus)
}
}

google apprequest格式：https://developers.google.com/assistant/conversational/df-asdk/reference/webhook/rest/Shared.Types/AppRequest#User.FIELDS.access_token

但是我收到的请求不包含任何accesstoken。

{
user:
   { locale: 'en-GB',params: {},accountLinkingStatus: 'LINKED',verificationStatus: 'VERIFIED',packageEntitlements: [],lastSeenTime: '2020-11-09T09:07:54Z' }
}

解决方法

我在应用程序请求的标题中找到了访问令牌

授权：'承载者'

headers:
   { host: '5cf1a2690f0c.ngrok.io','user-agent': 'Google-ActionsOnGoogle/1.0','content-length': '885','accept-encoding': 'gzip,deflate,br',authorization: 'Bearer < accesstoken >','content-type': 'application/json;charset=UTF-8','google-actions-api-version': '3','google-assistant-signature':
      '< google-assistant-signature >','x-forwarded-for': '66.249.84.212','x-forwarded-proto': 'https' }

根据文档，它将以以下格式显示在正文部分，但我在标题中找到了它。

{
user : {
  "idToken": string,"profile": {
    object (UserProfile)
  },"accessToken": string,"permissions": [
    enum (Permission)
  ],"locale": string,"lastSeen": string,"userStorage": string,"packageEntitlements": [
    {
      object (PackageEntitlement)
    }
  ],"userVerificationStatus": enum (UserVerificationStatus)
}
}
