How do I integrate with Python Scripts?

1. Use the following code in your Viabl.ai Platform knowledge-base

let result = xpertrule.onceAsync(function(completeCB) {
    //
    let script = "../../_scripts/test.py";
    let inputObject = {
        name: "Mr Magoo",
        age: 42,
        mugshot: "http://images.com/xyz123.png"
    };
    //
    const child_process = require("child_process");
    let result = child_process.spawnSync("python", [script, JSON.stringify(inputObject)], {encoding: "utf8", cwd: __dirname});

    if (result.stderr) {
        completeCB({ok: false, error: result.stderr});
    } else if (result.error) {
        completeCB({ok: false, error: JSON.stringify(result.error)});      
    } else {
        completeCB({ok: true, data: result.stdout});
    }
});
#python_result.val(JSON.stringify(result));

2. Include the following code in your Python script (test.py) on the server

    import sys
    import json

    inputObject = json.loads(sys.argv[1])

    inputObject['age'] = inputObject['age'] + 1

    print json.dumps(inputObject)

    sys.stdout.flush()
