I创建了一个顶点AI生成工作室AI提示。 我可以使用卷曲发布并得到回应。 但是,当我尝试创建云功能时,我无法获得授权。 似乎有指示...

DEFVERTEX_AI_REQUEST(请求): #定义常数 api_endpoint =“ us-central1-aiplatform.googleapis.com” project_id =“ xxxx” model_id =“ text-bison@001” url = f“ https:// {api_endpoint}/v1/projects/{project_id}/locuations/us-central1/us-central1/publishers/google/models/{model_id}:预测“

# Load the service account credentials credentials = service_account.Credentials.from_service_account_file( 'service-account-file.json' ) auth_req = requests.Request() token = credentials.refresh(auth_req).token # Define the headers headers = { "Authorization": f"Bearer {token}", "Content-Type": "application/json" } # Define the payload payload = { "instances": [ { "content": "Your content here ..." } ], "parameters": { "candidateCount": 1, "maxOutputTokens": 317, "temperature": 0.2, "topP": 0.8, "topK": 40 } } # Send the POST request response = req.post(URL, headers=headers, json=payload) # Print the response to the logs print(response.json()) return 'Request completed', 200

DEFVERTEX_AI_REQUEST(请求): #从环境中获取默认凭据 凭据,project_id = default()

# Define constants API_ENDPOINT = "us-central1-aiplatform.googleapis.com" MODEL_ID = "text-bison@001" # Or your deployed prompt endpoint URL = f"https://{API_ENDPOINT}/v1/projects/{project_id}/locations/us-central1/publishers/google/models/{MODEL_ID}:predict" # Get the access token auth_req = requests.Request() token = credentials.refresh(auth_req).token # Define the headers headers = { "Authorization": f"Bearer {token}", "Content-Type": "application/json" } # Define the payload payload = { "instances": [ { "content": "Your content here ..." } ], "parameters": { "candidateCount": 1, "maxOutputTokens": 317, "temperature": 0.2, "topP": 0.8, "topK": 40 } } # Send the POST request response = requests.post(URL, headers=headers, json=payload) # Print the response to the logs print(response.json()) return 'Request completed', 200

步骤部署和配置:

grant权限:
在Google Cloud Console中访问IAM页面。
查找云功能服务帐户(看起来像[Project_ID]

[电子邮件保护]

)。 授予它“顶点AI用户”角色。 部署云功能:

部署您的云功能。 如果您使用的是服务帐户文件,请确保将其删除,并删除加载文件的行。 测试:

触发云功能。 检查云功能日志以查看Vertex AI的响应。 如果您使用已部署的提示:

获取端点: 在Dertex AI提示工程UI中,部署提示后,您会找到端点URL。 更新Model_ID变量: 将“ text-bison@001”替换为已部署提示的端点。 更新有效载荷: 部署提示的有效负载结构可能与基本模型不同。查看已部署的提示的文档,并相应地更新有效载荷。
