我已经在python运行时环境中创建了一个由google cloud pubsub触发的google cloud函数，并且我还添加了需求依赖项，但是当我运行该函数时，它可以正常运行，但是记录了一些导入错误，所以我该如何解决这个问题问题。
python代码：
import base64
import json
from google.oauth2 import service_account
from googleapiclient import discovery
from googleapiclient.errors import HttpError
class IotDevice:
def __init__(self, service_account_json, project_id, cloud_region, registry_id, device_id):
api_scopes = ['https://www.googleapis.com/auth/cloud-platform']
api_version = 'v1'
discovery_api = 'https://cloudiot.googleapis.com/$discovery/rest'
service_name = 'cloudiotcore'
credentials = service_account.Credentials.from_service_account_file(service_account_json)
scoped_credentials = credentials.with_scopes(api_scopes)
discovery_url = '{}?version={}'.format(discovery_api, api_version)
self.client = discovery.build(service_name, api_version, discoveryServiceUrl=discovery_url,
credentials=scoped_credentials)
self.project_id = project_id
self.cloud_region = cloud_region
self.registry_id = registry_id
self.device_id = device_id
def set_config(self, version, config):
device_path = 'projects/{}/locations/{}/registries/{}/devices/{}'.format(
self.project_id, self.cloud_region, self.registry_id, self.device_id)
config_body = {
'versionToUpdate': version,
'binaryData': base64.urlsafe_b64encode(config.encode('utf-8')).decode('ascii')
}
try:
return self.client.projects().locations().registries().devices().modifyCloudToDeviceConfig(
name=device_path, body=config_body).execute()
except HttpError as e:
print(e.content.decode())
def get_config_versions(self):
registry_name = 'projects/{}/locations/{}/registries/{}'.format(
self.project_id, self.cloud_region, self.registry_id)
device_name = '{}/devices/{}'.format(registry_name, self.device_id)
devices = self.client.projects().locations().registries().devices()
configs = devices.configVersions().list(name=device_name).execute().get('deviceConfigs', [])
return configs[0].get('version')
# [END iot_get_device_configs]
def main(data, context):
if data is not None:
payload = base64.b64decode(data['data']).decode('utf-8')
payload = json.loads(payload)
attributes = data['attributes']
project_id = attributes['projectId']
location = attributes['deviceRegistryLocation']
registry_id = attributes['deviceRegistryId']
device_id = attributes['deviceId']
device = IotDevice('./service_account.json', project_id, location, registry_id, device_id)
config_version = device.get_config_versions()
value = payload["value"]
thresold = payload["thresold"]
if value > thresold:

else:

device.set_config(version=config_version, config=config)

答案 0 :(得分：0)
您可以隐藏日志消息：
import logging
logging.getLogger('googleapicliet.discovery_cache').setLevel(logging.ERROR)`
或在使用cache_discovery=False时设置discovery.build()：
self.client = discovery.build(
service_name,
api_version,
discoveryServiceUrl=discovery_url,
credentials=scoped_credentials,
cache_discovery=False,
)
