Usage

This is a web API call to start a job. Each job will comprise of 3 actions, namely;

• Extract content of report
• For each content of report, infer the classification
• Save the information from above into storage It simply calls other APIs to fulfil the above.

The JobService can be called by a HTTP POST call. Primarily on http://webserverip:port/create_job. It expects a json of the following format

[{"filename":"file01.pdf",},{"filename":"file02.pdf"}]

and will vomit a json of one of the following.

{"results": "ok"} #if things went well 
{"results": "nok"} #If things didn't go well

config.py

The configuration will point to the URLs of the relevant APIs, and also set the logging level of the service.
Note that log files are placed in /logs folder of the container by default.

    EXTRACTION_URL='http://extractionsvc:9891/extract_content'
    INFERENCE_URL='http://classifiersvc:9891/infer_content'
    SAVE_URL='http://savesvc:9891/savecontent'    
    LOGGINGLEVEL=logging.DEBUG

Flask

The API calls are coded in Flask. Upon deployment, they should be supported by a production WSGI server.
A test call is also provided to test if the service is running.

@app.route('/create_job', methods=['POST'])
def create_job_get():
    logging.info("Received CREATEJOB call")
    if request.method == 'POST':
        logging.debug("Getting json info")
        request_json = request.get_json(force=True)
        result = run_create_new_job(request_json)
        logging.debug("Dumping results back to caller")
        response_msg = json.dumps(result)
        response = {
            'results': response_msg
        }
        logging.info("Job call completed")
        return jsonify(response), 200

@app.route('/test',methods=['GET'])
def test_get():
    response = {
        'message':'ok'
    }
    return jsonify(response), 200
