如何使用Boto向端点发送请求

Question

I am trying to list items in a S3 container with the following code.

import boto.s3
from boto.s3.connection import OrdinaryCallingFormat

conn = boto.connect_s3(calling_format=OrdinaryCallingFormat())
mybucket = conn.get_bucket('Container001')

for key in mybucket.list():
    print key.name.encode('utf-8')

Then I get the following error.

Traceback (most recent call last):
  File "test.py", line 5, in <module>
    mybucket = conn.get_bucket('Container001')
  File "/usr/lib/python2.7/dist-packages/boto/s3/connection.py", line 370, in get_bucket
bucket.get_all_keys(headers, maxkeys=0)
File "/usr/lib/python2.7/dist-packages/boto/s3/bucket.py", line 358, in get_all_keys
'', headers, **params)
File "/usr/lib/python2.7/dist-packages/boto/s3/bucket.py", line 325, in _get_all

I tried to search for how to send requests to the specified end point, but couldn't find useful information.

How do I avoid this error?

Answer 1

As @garnaat mentioned and @Rico answered in another question connect_to_region works with OrdinaryCallingFormat :

conn = boto.s3.connect_to_region(
   region_name = '<your region>',
   aws_access_key_id = '<access key>',
   aws_secret_access_key = '<secret key>',
   calling_format = boto.s3.connection.OrdinaryCallingFormat()
   )
bucket = conn.get_bucket('<bucket name>')

Answer 2

in terminal run

nano ~/.boto

if there is some configs try to comment or rename file and connect again. (it helps me)

http://boto.cloudhackers.com/en/latest/boto_config_tut.html

there is boto config file directories. take a look one by one and clean them all, it will work by default configs. also configs may be in .bash_profile, .bash_source... I guess you must allow only KEY-SECRET

also try to use

calling_format = boto.s3.connection.OrdinaryCallingFormat()
