Overview
--------
The SDK of this version is dependent on the third-party HTTP library `requests <https://github.com/kennethreitz/requests>`_.
Running environment
-------------------
Python 2.7, Python 3.6
Notice
-------------------
fc and fc2 are not compatible, now master repo is fc2, if you still use fc, 1.x branch is what you need.
We suggest using fc2, The main difference between fc and fc2 is:
1, all http request fuction can set headers
.. code-block:: python
def invoke_function(self, serviceName, functionName, payload=None,
headers = {'x-fc-invocation-type': 'Sync', 'x-fc-log-type' : 'None'}):
...
Attention: abandon async_invoke_function, there is only one function interface invoke_function, distinguish between synchronous and asynchronous by x-fc-invocation-type parameters(Sync or Async).
.. code-block:: python
# sync invoke
client.invoke_function('service_name', 'function_name')
# async invoke
client.invoke_function('service_name', 'function_name', headers = {'x-fc-invocation-type': 'Async'})
2, The all http response returned by the user is the following object
.. code-block:: python
class FcHttpResponse(object):
def __init__(self, headers, data):
self._headers = headers
self._data = data
@property
def headers(self):
return self._headers
@property
def data(self):
return self._data
Note: for invoke function, data is bytes, for other apis, data is dict
Installation
-------------------
Install the official release version through PIP (taking Linux as an example):
.. code-block:: bash
$ pip install aliyun-fc2
You can also install the unzipped installer package directly:
.. code-block:: bash
$ sudo python setup.py install
if you still use fc, you can install the official fc1 release version through PIP (taking Linux as an example):
.. code-block:: bash
$ pip install aliyun-fc
Getting started
-------------------
.. code-block:: python

Testing
-------
To run the tests, please set the access key id/secret, endpoint as environment variables.
Take the Linux system for example:
.. code-block:: bash
$ export ENDPOINT=<endpoint>
$ export ACCESS_KEY_ID=<AccessKeyId>
$ export ACCESS_KEY_SECRET=<AccessKeySecret>
$ export STS_TOKEN=<roleARN>
Run the test in the following method:
.. code-block:: bash
$ nosetests # First install nose
