我正在构建一个简单的应用程序，它将 Twilio 凭据存储在 GCP Secret Manager 中，并在需要时将其拉下。但是，我在项目资源上不断收到拒绝权限错误 (403)：
google.api_core.exceptions.PermissionDenied：403 资源项目的权限被拒绝。
我使用的环境变量设置为包含服务帐户凭据的 JSON 文件的路径。
这是我已经尝试过的：
- 确保在 GCP Console 中正确设置权限。服务帐户被设置为项目的所有者、项目级别的秘密访问者以及每个秘密的对象级别的秘密访问者。
- 确保环境变量设置正确 - 我已经验证 ENV 变量设置正确并且可以读取它指向的文件。我可以通过将 ENV 变量作为 JSON 文件打开来打印文件的内容。
- 通过将 JSON 文件的内容与 GCP 控制台中的数据进行比较，确认身份验证信息正确
- 我已使用 gcloud CLI 在服务帐户下登录，然后使用 CLI 命令检索完全相同的机密
- 我可以成功访问数据并将其推送到 GCS 存储桶，这表明凭证已从 ENV 变量正确加载
- 我尝试过多种方式来了解这些秘密。我尝试过其他方法，例如列出项目中的秘密。全部返回权限错误。
作为参考，我一直遵循以下位置的说明https://cloud.google.com/secret-manager/docs/reference/libraries#client-libraries-install-python https://cloud.google.com/secret-manager/docs/reference/libraries#client-libraries-install-python并且还一直在使用官方客户端库文档来探索其他可能出现的问题。这里没有什么能真正帮助我。
我已经阅读了我能找到的所有资源，但没有任何帮助。有什么想法吗？
谢谢你！！！
编辑：添加以下代码：
def access_secret(project_id, secret_id, version):
"""
Access a secret- API token, etc- stored in Secret Manager
Code from https://cloud.google.com/secret-manager/docs/creating-and-accessing-secrets#secretmanager-access-secret-version-python
"""
client = secretmanager.SecretManagerServiceClient()
# Build the resource name of the secret version
name = client.secret_version_path(project_id, secret_id, version)
# Access the secret version
response = client.access_secret_version(name)
# Return the secret payload
payload = response.payload.data.decode('UTF-8')
return payload
EDIT2：这是我在其中运行此代码的 Dockerfile：
FROM python:3.8.2-slim-buster
WORKDIR /build
# Copy in the requirements.txt file and service account credentials
COPY requirements.txt <CREDENTIALS_FILENAME>.json /build/
ENV PYTHONUNBUFFERED=1 \
GOOGLE_APPLICATION_CREDENTIALS=/build/<CREDENTIALS_FILENAME>.json \
VOICEMAIL_TIMEOUT=55 \
MULTIRING_TIMEOUT=15 \
GCS_VM_BUCKET=<MY GCS BUCKET NAME> \
GCP_PROJECT=<MY GCP PROJECT NAME> \
PHONE_NUMBER=<PHONE NUMBER> \
TWILIO_ACCOUNT_SID_VERSION=1 \
TWILIO_AUTH_TOKEN_VERSION=1
# Install packages
RUN pip install -r requirements.txt
# Navigate to the directory containing the Python code
WORKDIR /code/src/
EXPOSE 5000
# Run the actual Python code
CMD ["python", "main.py"]
后来，我有了调用上面函数的Python代码：
GCS_VM_BUCKET = os.environ['GCS_VM_BUCKET']
GCP_PROJECT = os.environ['GCP_PROJECT']
TWILIO_SID = access_secret(GCP_PROJECT, 'TWILIO_ACCOUNT_SID', os.environ['TWILIO_ACCOUNT_SID_VERSION'])
TWILIO_AUTH_TOKEN = access_secret(GCS_PROJECT, 'TWILIO_AUTH_TOKEN', os.environ['TWILIO_AUTH_TOKEN_VERSION'])
其中 TWILIO_ACCOUNT_SID 和 TWILIO_AUTH_TOKEN 是 GCP 中密钥的名称。
完整的错误跟踪：
