Description: # ioFog Python SDK
        
        This SDK provides the following modules:
        * microservices: Clients for Microservices to talk to ioFog (e.g. ioMessage and Web Socket clients)
        * rest.controller: Client for Controller REST API
        
        ## Installation
        
        Install python package:
        ```bash
        sudo python3 -m pip install iofog
        ```
        
        ## Microservices
        
        This module lets you easily build an ioElement. It gives you all the functionality to interact with ioFog via Local API. It contains all necessary methods for IoMessage transformation as well.
        
         - send new message to ioFog (post_message)
         - fetch next unread messages from ioFog (get_next_messages)
         - fetch messages for time period and list of accessible publishers (get_next_messages_from_publishers_within_timeframe)
         - get config options (get_config)
         - create IoMessage, encode(decode) to(from) raw bytes, marshall(unmarshall) into(from) JSON object (IoMessage class methods)
         - connect to ioFog Control Channel via WebSocket (establish_control_ws_connection)
         - connect to ioFog Message Channel via WebSocket (establish_message_ws_connection) and publish new message via this channel (post_message_via_socket)
        
        ### Code snippets: 
        
        Import iofog client and additional classes to your project:
        ```python
        from iofog.microservices.client import IoFogClient
        from iofog.microservices.exception import IoFogException
        from iofog.microservices.iomessage import IoMessage
        from iofog.microservices.listener import *
        ```
        
        Create IoFog client with default settings:
        ```python
        try:
            client = IoFogClient()
        except IoFogException as e:
         # client creation failed, e contains description
        ```
        
        Or specify host, port, ssl and container id explicitly:
        ```python
        try:
            client = IoFogClient(id='container_id', host='iofog_host', port=6666)
        except IoFogException as e:
         # client creation failed, e contains description
        ```
        
        ##### REST calls
        
        Get list of next unread IoMessages:
        ```python
        try:
            messages = client.get_next_messages()
        except IoFogException as e:
         # some error occurred, e contains description
        ```
        
        Post new IoMessage to ioFog via REST call:
        ```python
        msg=IoMessage()
        msg.infotype="infotype"
        msg.infoformat="infoformat"
        msg.contentdata="sdkjhwrtiy8wrtgSDFOiuhsrgowh4touwsdhsDFDSKJhsdkljasjklweklfjwhefiauhw98p328946982weiusfhsdkufhaskldjfslkjdhfalsjdf=serg4towhr"
        msg.contextdata=""
        msg.tag="tag"
        msg.groupid="groupid"
        msg.authid="authid"
        msg.authgroup="authgroup"
        msg.hash="hash"
        msg.previoushash="previoushash"
        msg.nonce="nonce"
        
        try:
            receipt = client.post_message(msg)
        except IoFogException, e:
         # some error occurred, e contains description
        ```
        
        Get an array of IoMessages from specified publishers within given timeframe:
        ```python
        query = {
            	'timeframestart': 1234567890123,
            	'timeframeend': 1234567890123,
            	'publishers': ['sefhuiw4984twefsdoiuhsdf', 'd895y459rwdsifuhSDFKukuewf', 'SESD984wtsdidsiusidsufgsdfkh']
        }
        try:
            query_response = client.get_next_messages_from_publishers_within_timeframe(query)
        except IoFogException, e:
         # some error occurred, e contains description
        ```
        
        Get container's config:
        ```python
        try:
            config = client.get_config()
        except IoFogException, ex:
         # some error occurred, ex contains description
        ```
        
        
        ##### WebSocket calls
        
        To use websocket connections you should implement listeners as follows:
        ```python
        class MyControlListener(IoFogControlWsListener):
            def on_control_signal(self):
                # do smth on control signal
        
        
        class MyMessageListener(IoFogMessageWsListener):
            def on_receipt(self, message_id, timestamp):
                # do smth with message receipt
        
            def on_message(self, io_msg):
                # do smth with new message
        
        ```
        
        After that you can establish websocket connections:
        ```python
        client.establish_message_ws_connection(MyMessageListener())
        client.establish_control_ws_connection(MyControlListener())
        ```
        Each of those connections will be managed in a separate thread.
         
         
        After successful connection to message websocket you can send to it:
        ```python
        client.post_message_via_socket(io_msg_instance)
        ```
        
        
        ##### Message utils
        
        Construct IoMessage from JSON(both json string and python dictionary are acceptable):
        ```python
        msg = IoMessage.from_json(json_msg)
         ```
        
        IoMessage to JSON:
        ```python
        json_str = io_msg_instance.to_json()
        ```
        
        Construct IoMessage from raw bytes:
        ```python
        msg = IoMessage.from_bytearray([0, 4, ...])
        ```
        
        Pack IoMessage into bytearray:
        ```python
        msg_bytes = io_msg_instance.to_bytearray()
        ```
        
        #### Logging
        
        ```python
        from iofog.microservices.log import Logger
        
        log = Logger("first")
        log.debug("hello")
        log.info("world")
        log.warn("good")
        log.error("bye")
        ```
         
        #### Disclaimer
        
        These modules are a Work In Progress. It was first written as a set of helper functions used by a python script to deploy a set of microservices configured using yaml files.
        
        Our [golang SDK](https://github.com/eclipse-iofog/iofog-go-sdk) is highly recommended as Controller REST API client.
