About OSS SDK for Python V2
--------
OSS SDK for Python V2 `alibabacloud-oss-python-sdk-v2 <https://github.com/aliyun/alibabacloud-oss-python-sdk-v2>`_ beta version has been released, it is a major rewrite of OSS SDK for Python V1 (aliyun-oss-python-sdk).

V2 simplifies underlying operations such as identification authentication, automatic retry of failed requests, and error handling. It provides flexible parameter configuration methods and rich advanced operations, such as paginator, transmission managers, and File-like operations. This comprehensively improves development efficiency and experience.


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. 

Running environment
-------------------

Python 2.6(not recommended)，2.7，3.3(not recommended)，3.4，3.5，3.6


Note:
    Python 2.6 is not recommended because it is no longer supported by the Python core team. 
    Do not use Python 3.3.0 or 3.3.1. Refer to `Python Issue 16658 <https://bugs.python.org/issue16658>`_.

Installing
----------

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


Getting started
---------------

.. 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. 

Handling 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))

Setup Logging
---------------

The following code can set the logging level of 'oss2'.
 .. code-block:: python

    import logging
    logging.getLogger('oss2').setLevel(logging.WARNING)

Testing
-------

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


You can set environment variable to test auth v2:

.. code-block:: bash

    $ export OSS_TEST_AUTH_VERSION=v2
