The PDK (plugin developemet kit) API document can be viewed here.
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
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
.
# 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
