部署时发生云函数抛出错误

Question

在部署云功能时，我收到了下面提到的错误

我正在requirements.txt中使用云存储的最新版本此外，我正在使用存储客户端的list_blob功能，从那时起，我在部署功能时面临以下错误

ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Function failed on loading user code.

Answer 1

我测试了您的代码，当它被包装在正确的HTTP函数格式中时，它可以完美地工作

#Your function
def list_blobs(bucket_name):
from google.cloud import storage
storage_client = storage.Client()
blobs = storage_client.list_blobs(bucket_name)
fileList = []
for blob in blobs:
fileList.append(blob.name)
return fileList
#function wrapper
def test_list_blob(request):
ret = list_blobs('temp-veolia-export')
return str(ret),200

并部署

gcloud functions deploy --trigger-http --entry-point=test_list_blob --runtime=python37 
--region=us-central1 --allow-unauthenticated python-test-storage
