py-data-transfer

Try some ways to transfer data in Python

System requirements

• Ubuntu 18.04 or newer
• Python 3.6.5 or newer

Setup

git clone https://github.com/ndaidong/py-data-transfer.git
cd  py-data-transfer
python3 -m venv venv
source venv/bin/activate
(venv) pip install -r requirements.txt

Usage

There are 5 different methods in 5 sub folders:

• autobahn
• pure-python-udp
• pure-python-tcp
• python-socketio
• redis

In each of folder, we have 2 files server.py and client.py. server.py and client.py should be ran at the different machines. However, running them on the same machine is good to start too.

With each of method, please run server.py first, for example in a terminal tab:

cd /path/to/py-data-transfer
source venv/bin/activate
(venv) python python-socketio/server.py

Then, start client.py at another tab:

cd /path/to/py-data-transfer
source venv/bin/activate
(venv) python python-socketio/client.py

Check these 2 tabs to see the result.

We can specify HOST and PORT as regular environment variables:

# server
(venv) PORT=8182 python python-socketio/server.py

# client must connect to the same port
(venv) PORT=8182 python python-socketio/client.py

# if server is running at another IP
(venv) HOST=192.168.1.170 PORT=8182 python python-socketio/client.py

With redis part, we need Redis server runs at specific port.

We recommend to build Redis from source as below:

export VERSION=5.0.4

wget http://download.redis.io/releases/redis-$VERSION.tar.gz
tar xzf redis-$VERSION.tar.gz
cd redis-$VERSION
make

Then start redis-server:

cd /path/to/redis-$VERSION
src/redis-server --port=7642 --protected-mode no
