Use Library as client

This snippet shows how to use the WASDI Lib as client, to run applications and get results.

Prerequisites

To run this code you need:

  • A running Python 3.x Environment

  • A valid WASDI Account

  • A valid Config file

If this is not clear, you probably need to take a look to the Python Tutorial before.

Recipe

We are going to init the WASDI Lib, call an application and get back the result

Note

Often WASDI is used to deploy application, but in the same lib can be used also as a Client of WASDI.

Note

In this sample we use hellowasdiworld application that DOES NOT produce any file, so this snippet as it is will not dowload locally any file. In the real life you will probably use an app that will add some file in the workspace.

# Initialize the lib: you must set the right path to your config file
wasdi.init('myconfig.json')

# Create a workspace where we will run our application
wasdi.createWorkspace('NAME')

# Create the dictionary with the params to pass to the application
aoParams = {}
aoParams['NAME'] = “Test”

# Run the application: Applications are ALWAYS executed in asynchronous way
sProcessId = wasdi.executeProcessor("hellowasdiworld", aoParams)

# Here you are free to do what you want
wasdi.wasdiLog("I started an app and I can do what I want")

# Call this when you need to wait for it to finish
wasdi.waitProcess(sProcessId)

# Get the List of Files in Workspace
asFilesProduced = wasdi.getFileByActiveWorkspace()

# For all the files produced
for sFile in asFilesProduced
   # Since you are running out of wasdi, this will take the produced files locally for you
   wasdi.getPath(file)

What it does:

  • Initializes the lib

  • Creates a workspace

  • Creates the parameters for the app

  • Starts the app

  • Waits for it

  • Get the files in the workspace

  • Get a local copy of all the produced files
