# kong-python-pluginserver

[![PyPI version](https://badge.fury.io/py/kong-pdk.svg)](https://badge.fury.io/py/kong-pdk)

Plugin server and PDK (Plugin Development Kit) for Python language support in Kong.

Requires Kong >= 2.3.0.


## Documentation

See in [Kong Docs](https://docs.konghq.com/gateway/latest/plugin-development/pluginserver/python/)

## Install the plugin server

```shell
pip3 install kong-pdk
```

## Usage

```
usage: kong-python-pluginserver [-h] [-p prefix] [-v] [--version] [--socket-name SOCKET_NAME] [--listen-queue-size LISTEN_QUEUE_SIZE]
                         [--no-lua-style] [-m | -g] -d directory [--dump-plugin-info name] [--dump-all-plugins]

Kong Python Plugin Server.

optional arguments:
  -h, --help            show this help message and exit
  -p prefix, --kong-prefix prefix, -kong-prefix prefix
                        unix domain socket path to listen (default: /usr/local/kong/)
  -v, --verbose         turn on verbose logging (default: 1)
  --version, -version   show program's version number and exit
  --socket-name SOCKET_NAME
                        socket name to listen on (default: python_pluginserver.sock)
  --listen-queue-size LISTEN_QUEUE_SIZE
                        socket listen queue size (default: 4096)
  --no-lua-style        turn off Lua-style "data, err" return values for PDK functions and throw exception instead (default: False)
  -m, --multiprocessing
                        enable multiprocessing (default: False)
  -g, --gevent          enable gevent (default: False)
  -d directory, --plugins-directory directory, -plugins-directory directory
                        plugins directory
  --dump-plugin-info name, -dump-plugin-info name
                        dump specific plugin info into stdout
  --dump-all-plugins, -dump-all-plugins
                        dump all plugins info into stdout
```

## PDK API reference

The PDK (plugin developemet kit) API document can be viewed [here](https://kong.github.io/kong-python-pdk/).

Reference is generated by Sphinx under `doc` folder and published to the `gh-pages` branch.
To generate updated docs, use:
```
git worktree add docs/build/html gh-pages
cd docs
make deps && make html
``` 

## Deprecation Notice

In next major release of Kong Python PDK, return values will default to use Python style error handling instead of
Lua style. The new style API can be turned on now with `--no-lua-style`.

```python
# old lua-style PDK API
host, err = kong.request.get_header("host")
if err:
    pass # error handling

# new python-style PDK API
try:
    host = kong.request.get_header("host")
    # no err in return, instead they are thrown if any
except Exception as ex:
    pass # error handling
```
