------------------

Overview
----

Alibaba Cloud Object Storage Python SDK 2.x. This version is not compatible with the previous version (Version 0.x). The package name is `oss2` to avoid conflict with previous versions.


The SDK of this version is dependent on the third-party HTTP library `requests <https://github.com/kennethreitz/requests>`_ and `crcmod`. Install the SDK following the methods below.

Note:

This version does not contain the `osscmd` command line tool.

Run environment
--------

Python 2.6，2.7，3.3，3.4，3.5

.. note::

Do not use Python 3.3.0 or 3.3.1. Refer to `Python Issue 16658 <https://bugs.python.org/issue16658>`_.

Installation method
--------

Install the official release version through PIP (taking Linux as an example):

.. code-block:: bash

$ pip install oss2

You can also install the unzipped installer package directly:

.. code-block:: bash

$ sudo python setup.py install


Quick use
--------

.. code-block:: python

# -*- coding: utf-8 -*-

import oss2

endpoint = 'http://oss-cn-hangzhou.aliyuncs.com' # Suppose that your bucket is in the Hangzhou region.

auth = oss2.Auth('<Your AccessKeyID>', '<Your AccessKeySecret>')
bucket = oss2.Bucket(auth, endpoint, '<your bucket name>')

# The object key in the bucket is story.txt
key = 'story.txt'

# Upload
bucket.put_object(key, 'Ali Baba is a happy youth.')

# Download
bucket.get_object(key).read()

# Delete
bucket.delete_object(key)

# Traverse all objects in the bucket
for object_info in oss2.ObjectIterator(bucket):
print(object_info.key)

For more examples, refer to the code under the "examples" directory.

Handle errors
--------

The Python SDK interface will throw an exception in case of an error (see oss2.exceptions sub-module) unless otherwise specified. An example is provided below:

.. code-block:: python

try:
result = bucket.get_object(key)
print(result.read())
except oss2.exceptions.NoSuchKey as e:
print('{0} not found: http_status={1}, request_id={2}'.format(key, e.status, e.request_id))

Test
----

First set the required AccessKeyId, AccessKeySecret, endpoint and bucket information for the test through environment variables (**Do not use the bucket for the production environment**).
Take the Linux system for example:

.. code-block:: bash

$ export OSS_TEST_ACCESS_KEY_ID=<AccessKeyId>
$ export OSS_TEST_ACCESS_KEY_SECRET=<AccessKeySecret>
$ export OSS_TEST_ENDPOINT=<endpoint>
$ export OSS_TEST_BUCKET=<bucket>

$ export OSS_TEST_STS_ID=<AccessKeyId for testing STS>
$ export OSS_TEST_STS_KEY=<AccessKeySecret for testing STS>
$ export OSS_TEST_STS_ARN=<Role ARN for testing STS>


Run the test in the following method:

.. code-block:: bash

$ nosetests # First install nose
