对用户进行身份验证

除此之外，代理通常对他们通信的用户知之甚少根据用户在对话中提供的信息生成。不过，客服人员可以使用 OAuth 对用户进行身份验证以确认用户身份、代表用户执行个性化对话以及执行操作用户。

在此对话流程中，用户选择为账号充值，并且代理提示用户登录以验证用户的身份，并下订单获取用户信息。

用户发起与代理的对话。

用户开始输入回复后，会向代理发送输入事件。

{
  "agent": "brands/1111/agents/2222",
  "conversationId": "3333",
  "customAgentId": "oauth",
  "requestId": "1234567890",
  "userStatus": {
    "isTyping": "true",
    "createTime": "2020-10-02T15:01:23.045123456Z",
  },
  "sendTime": "2020-10-02T15:01:24.045123456Z",
}

用户发送“Hi, I'd like to add 5 credit to my account”消息。

{
  "agent": "brands/1111/agents/2222",
  "conversationId": "3333",
  "customAgentId": "oauth",
  "requestId": "123123123",
  "message": {
    "messageId": "4444",
    "name": "conversations/12345/messages/67890",
    "text": "Hi, I'd like to add 5 credits to my account",
    "createTime": "2020-10-02T15:05:23.045123456Z",
  },
  "context": {
    "entryPoint": "PLACESHEET",
    "userInfo": {
      "displayName": "Michael",
      "userDeviceLocale": "en",
    },
    "resolvedLocale": "en",
  }
  "sendTime": "2020-10-02T15:05:24.045123456Z",
}

客服人员会说：“我可以为您提供帮助。登录您的账号以继续。”以及身份验证请求建议。

clientId 和 scopes 由 OAuth 提供方定义。代理根据 OAuth 提供方的codeChallenge 要求。

curl -X POST "https://businessmessages.googleapis.com/v1/conversations/3333/messages" \
-H "Content-Type: application/json" \
-H "`oauth2l header --json path/to/service/account/key.json businessmessages`" \
-d "{
  'messageId': '5555',
  'text': 'I can help you with that. Sign into your account to continue.',
  'suggestions': [
    {
      'AuthenticationRequest': {
        'clientId': 'oauth_client_id_1234567890',
        'codeChallenge': 'code_challenge',
        'scopes': [
          'account',
          'billing',
        ],
      },
    },
  ],
  'representative': {
    'avatarImage': 'https://oauth.agent/bot-avatar.jpg',
    'displayName': 'OAuth Agent',
    'representativeType': 'BOT'
  }
}"

用户收到该消息，点按身份验证请求建议，并登录其账号。

代理将收到一条消息，其中包含 authenticationResponse.code 字段。

{
  "agent": "brands/1111/agents/2222",
  "conversationId": "3333",
  "customAgentId": "oauth",
  "requestId": "1234567895",
  "authenticationResponse": {

    },
  }
  "sendTime": "2020-10-02T15:01:24.045123456Z",
}

代理与 OAuth 提供方通信，交换授权用于访问令牌的代码并获取用户的账号信息。
