Flask SOAP Server Mock

A simple example of how to use Flask to build a SOAP server from WSDL files.

Pre-Requisites

Make sure you have locally installed:

• Pipenv

Usage

Open your terminal and go to your directory flask-soap-server-mock. You can decide to deploy the server in two ways:

1. locally

~$ pipenv install
~$ ./bootstrap.sh

2. via Docker

# Build image
~$ docker build -t flasksoap:latest .
# Run the container
~$ docker run --name flask -d -p 5000:5000 flasksoap

You can now issue requests to your API as you prefer. An example is given by the provided SOAP client, which triggers sample requests to the server and parses returned responses.

~$ cd client
~$ pipenv install && pipenv shell
(client) ~$ ./cli.py --help
Usage: cli.py [OPTIONS] COMMAND [ARGS]...

Options:
  --version            Show the version and exit.
  -H, --host TEXT      SOAP Web Server
  -p, --port TEXT      Web Server Port
  -U, --username TEXT  Username to login
  -P, --password TEXT  Password to login
  --help               Show this message and exit.

Commands:
  download
  edit
  login

Example: Login

(client) ~$ ./cli.py login
Response code '0' with message 'Welcome back'

Customisations

Assign a public endpoint to your local flask application

When your SOAP client is hosted in an external machine, your flask server running locally requires a public URL to be reachable. An easy solution would be using ngrok.

• If never used before, register and follow instructions to install and locally configure it
• In terminal execute ngrok http 5000
• Among printed output you should see a line starting with Forwarding, specifying something similar to http://xyz.ngrok.io -> localhost:5000
• Make sure that:
  • your SOAP binding location uses this hostname and port, and
  • your client points to this URL

Add another WSDL service

• Add your wsdl file to server/templates/wsdl
• Make sure wsdl binding location matches <soap12:address location="{{ binding }}" />
• Integrate your new routes in server/index.py similarly to what's done in the example

The binding automatically discovers the requesting host. Manual changes are possible.

Add another SOAP response

Similarly to response.xml, create your own template in server/templates and refers to it when building your route(s) in index.py.
