Reference implementation for a LIMS communicating with Aker to exchange product catalogues and work orders.
These scripts run in Python 2. postproducts.py requires the requests module, which you can install using pip install requests; or simply download the requests module so that the script can use it.
This script reads a text file (see examples in repository), constructs a JSON request, and posts it to a specified url as a catalogue.
The current version of the script uses trust_env=False to avoid using an http_proxy environment variable in your shell.
Example:
./postproducts.py -u http://workordersurl:4000/catalogue -f sequencing.txt
Run ./postproducts.py -h to see the usage information.
The catalogue file mostly consists of key:value pairs. At the top are properties of the catalogue:
pipeline: Sequencing
url: http://localhost:3400
lims_id: Sequencing
The url indicates what url the work orders service should post work orders to for this catalogue. You can find the IP address of your Mac using
ipconfig getifaddr en0
Following that in the file there should be zero or more product specifications. Each one begins with the word "product" on a line on its own, and then key-value pairs indicating the properties of that product.
PRODUCT
name: Toast
description: Hot delicious toast
product_version: 4
... more properties
PRODUCT
name: Cake
description: Blurple cake
product_version: 2
(The indentation and blank lines are for readability only; the script will ignore them.) The properties are read and sent off agnostically: you can put whatever properties in here you want, and the script will happily send them, but the work orders service might not happily receive them.
This script listens for posts on a specified port (default 3400). It will carry on listening until it errors (or quit via ctrl c). While it runs, it keeps a list of all posts it has received, and outputs the complete list to stdout each time a new one comes in.
Examples:
./receiveworkorders.py # default port
./receiveworkorders.py -p 8000 # port 8000
Run ./receiveworkorders.py -h to see the usage information.
In Windows, you need to have a Python 2 executable in your PATH and use it explicitly to run the scripts.
Examples:
python receiveworkorders.py
python postproducts.py -u http://workordersurl:4000/catalogue -f sequencing.txt
