Google对话框流程PERMISSION_DENIED异常 [英] Google dialogflow PERMISSION_DENIED Exception

问题描述

我正在尝试从Windows Java应用程序访问Google DialogFlow.我已经正确设置了环境变量 GOOGLE_APPLICATION_CREDENTIALS ，并且我可以调用其他Google API.但是，当我打电话时:

I am trying to access a Google DialogFlow from a Windows Java application. I have the environment variable, GOOGLE_APPLICATION_CREDENTIALS, properly set and I can call other Google APIs. However, when I call:

DetectIntentResponse响应= sessionClient.detectIntent(session，queryInput);

我收到一个grpc异常:

I receive a grpc exception:

PERMISSION_DENIED:拒绝了'projects/newagent-a0ef5/agent'上的IAM权限'dialogflow.sessions.detectIntent'.会话路径:projects/NewAgent/agent/sessions/xxxx

PERMISSION_DENIED: IAM permission 'dialogflow.sessions.detectIntent' on 'projects/newagent-a0ef5/agent' denied.Session Path: projects/NewAgent/agent/sessions/xxxx

"newagent-a0ef5"；是我流程的项目ID."xxxx"只是一个随机的会话ID令牌.

"newagent-a0ef5" is the project ID of my flow. "xxxx" is just a random Session ID token.

我了解我必须启用 dialogflow.sessions.detectIntent 访问权限，但是我无法确定在哪里.我使用该值创建了一个自定义角色，并将其添加到与流程相关联的三个IAM帐户中.我还启用了DialogFlow API.

I understand that I have to enable dialogflow.sessions.detectIntent access, but I cannot figure out where. I created a custom role with that value and added it to the three IAM accounts associated with my flow. I have also enabled the DialogFlow API.

有人知道我在哪里添加此丢失的权限吗?

Does anyone know where I add this missing permission?

推荐答案

我正确执行了所有IAM步骤，但是我将错误的Project ID传递给detectIntent.所以我猜有几件事要检查...

I did all the IAM steps properly, but I was passing the wrong Project ID to detectIntent. So I guess a couple things to check...

• 确保项目ID是正确的.您的会话路径应为项目/<项目ID>/agent/sessions/<会话ID>".
• 确保您使用的服务帐户具有Dialogflow API客户端角色.
• 尝试使其在 API资源管理器
