Serve WSGI applications¶
Hypercorn directly serves ASGI applications, but it can be used to
serve WSGI applications by using AsyncioWSGIMiddleware or
TrioWSGIMiddleware middleware. To do so simply wrap the WSGI
app with the appropriate middleware for the hypercorn worker,
from hypercorn.middleware import AsyncioWSGIMiddleware, TrioWSGIMiddleware
asyncio_app = AsyncioWSGIMiddleware(wsgi_app)
trio_app = TrioWSGIMiddleware(wsgi_app)
which can then be served by hypercorn,
$ hypercorn module:asyncio_app
$ hypercorn --worker-class trio module:trio_app
Warning
The full response from the WSGI app will be stored in memory before being sent. This prevents the WSGI app from streaming a response.
Limiting the request body size¶
As the request body is stored in memory before being processed it is
important to limit the max size. Both the AsyncioWSGIMiddleware
and TrioWSGIMiddleware have a default max size that can be
configured,
app = AsyncioWSGIMiddleware(wsgi_app, max_body_size=20) # Bytes
