threema.gateway 5.0.0

An API for the Threema gateway service to send and receive messages including text, images, files and delivery reports.

threema-gateway is a Python 3 module for the Threema gateway service. This API can be used to send and receive text messages to and from any Threema user.

Note

On machines where Python 3 is not the default Python runtime, you should use pip3 instead of pip.

Prerequisites

$ sudo apt-get install python3 python3-pip

We recommend using venv to create an isolated Python environment:

$ pyvenv venv

You can switch into the created virtual environment venv by running this command:

$ source venv/bin/activate

While the virtual environment is active, all packages installed using pip will be installed into this environment.

To deactivate the virtual environment, just run:

$ deactivate

If you want easier handling of your virtualenvs, you might also want to take a look at virtualenvwrapper.

Installation

If you are using a virtual environment, activate it first.

Install the module by running:

$ pip install threema.gateway

The dependency libnacl will be installed automatically. However, you may need to install libsodium for libnacl to work.

Command Line Usage

The script threema-gateway provides a command line interface for the Threema gateway. Run the following command to see usage information:

$ threema-gateway --help

Examples

You can find a few example scripts in the examples/ directory.

Note that most of them need to be adjusted to at least add your gateway ID credentials before they run successfully.

Contributing

If you want to contribute to this project, you should install the optional dev requirements of the project in an editable environment:

$ git clone https://github.com/lgrahl/threema-msgapi-sdk-python.git
$ cd threema-msgapi-sdk-python
$ pip install -e .[dev]

Before creating a pull request, it is recommended to run the following commands to check for code style violations (flake8), optimise imports (isort) and run the project’s tests:

$ flake8 .
$ isort -rc .
$ py.test

You should also run the type checker that might catch some additional bugs:

$ mypy setup.py tests examples threema

Changelog

5.0.0 (2021-05-17)

• Added custom session and session arguments to Connection (#55, #56)

• Removed the fingerprint and verify_fingerprint arguments, see #55 for a detailed explanation and how to achieve pinning

4.0.0 (2021-01-23)

General:

• Dropped support for Python versions below 3.6.1.

• Deprecated ReceiptType.user_ack has been removed. Use ReceiptType.user_acknowledge instead.

• util.aio_run has been simplified. It does not allow for passing a specific event loop or closing the event loop on completion any longer.

• util.aio_run_proxy_decorator has been renamed to aio_run_proxy and now always creates the class instance within a running event loop.

Client:

• In async mode, creation of the Connection instance must now be done within an async function.

• If you have used a with context manager block in async mode before, you must now do this within an async with asynchronous context manager. No change is required in blocking mode.

• Connection.close is now an async function.

Server:

• The callback server has been refactored and the AbstractCallback class has been removed for more flexibility and control of the underlying aiohttp server. Take a look at examples/callback.py on how to use it.

• The callback server CLI has been removed because it was redundant. The example provides the same functionality.
