User Application

User Application#

Tryton provides a way to connect URL rules to an callable endpoint using the decorator method route of the trytond.wsgi.app instance. This allows you to define a custom API based on HTTP that can be used to create a specific user application.

The decorator takes as first parameter a string which follow the Rule Format of Werkzeug and as second parameter sequence of HTTP methods.

Example:

from trytond.wsgi import app

@app.route('/hello', methods=['GET'])
def hello(request):
    return 'Hello world'

The following converter is added by Tryton:

base64

This converter accepts any Base64 string and transforms it into its corresponding bytes value.

Tryton also provides some wrappers in trytond.protocols.wrappers to ease the creation of such route.

set_max_request_size(size)

Change the default limit of the request to the size in bytes.

allow_null_origin

Allow requests which have their Origin set to null.

with_pool

Take the first parameter as database name and replace it by the corresponding instance of the Pool.

with_transaction([readonly[, user[, context[, timeout]]]])

Start a Transaction using the Pool from with_pool. If readonly is not set, the transaction will not be readonly for POST, PUT, DELETE and PATCH methods and readonly for all others.

user_application(name[, json])

Set the user from the Authorization header using the type bearer and a valid key for the named user application.

User Application Key#

Tryton also provides a easy way to manage access to user application using keys per named application. A key is created with a POST request on the URL /<database_name>/user/application/ which returns the key. The request must contain as data a JSON object with the keys:

user

The user login.

application

The name of the application.

After the creation, the key must be validated by the user from the preferences of a Tryton client.

A key can be deleted with a DELETE request on the same URL. The request must contain as data a JSON object with the keys:

user

The user login.

key

The key to delete.

application

The name of the application of the key.
