python的服务器、客户端被拒绝访问_无服务器AWS（Python）从S3读取：访问被拒绝...
我有一个问题，从我的lambda函数(FrameWork serverless)到AWS中的S3服务的getObject访问 . 这里是我的代码示例：
import boto3
import csv
def hello(event, context):
s3 = boto3.resource('s3')
bucket = s3.Bucket('myBucket')
obj = bucket.Object(key='MOCK_DATA.csv')
response = obj.get()
lines = response['Body'].read().split()
body = []
for row in csv.DictReader(lines):
body.append(row)
return body
在我的serverless.yml中，我给了我的lambda完全访问存储桶
iamRoleStatements:
- Effect: "Allow"
Action:
- "s3:*"
Resource:
- "arn:aws:s3:::myBucket"
但是当我运行代码时，我收到错误：
START RequestId: a6c006b7-21e5-11e8-8193-c3378825927 Version: $LATEST
An error occurred (AccessDenied) when calling the GetObject operation: Access Denied: ClientError
Traceback (most recent call last):
File "/var/task/handler.py", line 5, in hello
response = obj.get()
File "/var/runtime/boto3/resources/factory.py", line 520, in do_action
response = action(self, *args, **kwargs)
File "/var/runtime/boto3/resources/action.py", line 83, in call
response = getattr(parent.meta.client, operation_name)(**params)
File "/var/runtime/botocore/client.py", line 317, in _api_call
return self._make_api_call(operation_name, kwargs)
File "/var/runtime/botocore/client.py", line 615, in _make_api_call
raise error_class(parsed_response, operation_name)
ClientError: An error occurred (AccessDenied) when calling the GetObject operation: Access Denied
你知道为什么boto3不能获得iam角色的许可吗？因为只有当我使用私钥和访问密钥声明boto3时它才起作用：
s3 = boto3.resource('s3',aws_access_key_id='accesskey',aws_secret_access_key='privateKey')
先感谢您
