boto - 钥匙到底是什么？
boto - What exactly is a key?
正如标题所说，boto中的key是什么？
- 它封装了什么（字段、数据结构、方法等）？
- 如何使用 key/boto 访问 AWS 存储桶中文件的文件内容？
我无法在他们的官方文档或任何其他第三方网站上找到此信息。有人可以提供此信息吗？
以下是 key object 的一些用法示例：
def download_file(key_name, storage):
key = bucket.get_key(key_name)
try:
storage.append(key.get_contents_as_string())
except:
print "Some error message."
和：
for key in keys_to_process:
pool.spawn_n(download_file, key.key, file_contents)
pool.waitall()
由于您似乎在谈论简单存储服务 (S3)，因此您会在 S3 文档的第 1 页找到该信息。
Each object is stored and retrieved using a unique developer-assigned key.
A key is the unique identifier for an object within a bucket. Every object in a bucket has exactly one key. Because the combination of a bucket, key, and version ID uniquely identify each object, Amazon S3 can be thought of as a basic data map between "bucket + key + version" and the object itself. Every object in Amazon S3 can be uniquely addressed through the combination of the web service endpoint, bucket name, key, and optionally, a version. For example, in the URL http://doc.s3.amazonaws.com/2006-03-01/AmazonS3.wsdl, "doc" is the name of the bucket and "2006-03-01/AmazonS3.wsdl" is the key.

密钥只是一个字符串 -- 存储桶中对象的“路径和文件名”，没有前导 /。
在您的代码示例中 - 键是对存储桶中唯一标识符的对象引用。
将存储桶视为数据库中的 table
将键视为 table 中的行
您引用存储桶中的密钥（更广为人知的对象）。
通常在 boto（不是 boto3）中这样工作
from boto.s3.connection import S3Connection
connection = S3Connection() # assumes you have a .boto or boto.cfg setup
bucket = connection.get_bucket('my_bucket_name_here') # this is like the table name in SQL, select OBJECT form TABLENAME
key = bucket.get_key('my_key_name_here') this is the OBJECT in the above SQL example. key names are a string, and there is a convention that says if you put a '/' in the name, a viewer/tool should treat it like a path/folder for the user, e.g. my/object_name/is_this is really just a key inside the bucket, but most viewers will show a my folder, and an object_name folder, and then what looks like a file called is_this simply by UI convention
