无法读取实例数据，从而放弃python boto中的错误 [英] Unable to read instance data, giving up error in python boto

问题描述

我正在尝试使用Boto库访问Amazon s3，以访问亚马逊"aws-publicdatasets"中可用的常见爬网数据.

I am trying to access amazon s3 using boto library to access common crawl data availble in amazon 'aws-publicdatasets'.

我在〜/.boto中创建了访问配置文件

i created access config file in ~/.boto

[Credentials]
aws_access_key_id = "my key"
aws_secret_access_key = "my_secret"

并在与Amazon S3建立连接时，我在日志中看到以下错误.

and while creating connection with amazon s3 i see below error in logs.

2014-01-23 16:28:16,318 boto [DEBUG]:Retrieving credentials from metadata server.
2014-01-23 16:28:17,321 boto [ERROR]:Caught exception reading instance data

    raise URLError(err)

2014-01-23 16:28:17,323 boto [ERROR]:Unable to read instance data, giving up

另一种方式是我尝试在创建连接对象时提供凭据，如下所示

In other way I tried to give credentials while creating connection object also as shown below

from boto.s3.connection import S3Connection
from boto.s3.bucket import Bucket
boto.set_stream_logger('boto')
connection = S3Connection('______','__________')    
bucket = Bucket(connection.get_bucket('aws-publicdatasets'))

仍然在日志中看到相同的错误

Still i am seeing the same error in logs

推荐答案

在与脚本相同的文件夹中使用.boto文件时，我遇到了相同的错误.它必须位于主文件夹的基础上.

I had the same error when using a .boto file in the same folder as the script. It has to be on the base of the home folder.
