Tools to make ASGI Applications
Project description
asgi-tools – Tools to make ASGI Applications
Features:
Request – Parse ASGI scope, get url, headers, cookies, read a request’s data/json/form-data
Response – Send HTTP (html, json) responses
RequestMiddleware – Parse a scope and insert the parsed request into the scope
ResponseMiddleware – Parse responses and convert them into ASGI messages
RouterMiddleware – Route HTTP requests
LifespanMiddleware – Process a lifespan cycle
AppMiddleware – A combined (request, response, router, lifespan) middleware to quikly create ASGI apps
Requirements
python >= 3.7
Installation
asgi-tools should be installed using pip:
pip install asgi-tools
Usage
asgi_tools.Request, asgi_tools.Response
Parse HTTP Request data from a scope and build a http response:
from asgi_tools import Request, Response
template = "... any template for the HTML content here ..."
async def app(scope, receive, send):
if scope['type'] != 'http':
return
# Parse the given scope
request = Request(scope, receive, send)
# Render the page
body = template.render(
# Get full URL
url=request.url,
charset=request.charset,
# Get headers
headers=request.headers,
# Get query params
query=request.query,
# Get cookies
cookies=request.cookies,
# Get a decoded request body (the methods: request.body, request.form, request.json also available)
text=await request.text(),
)
# Render a response as HTML (HTMLResponse, PlainTextResponse, JSONResponse, StreamResponse, RedirectResponse also available)
return await Response(body, content_type="text/html")(scope, receive, send)Response/Request Middlewares
Automatically convert a scope into a asgi_tools.Request
from asgi_tools import RequestMiddleware
async def base_app(request, receive, send):
assert request.url
assert request.headers
# ...
app = RequestMiddleware(base_app)Automatically parse an result from asgi apps and convert it into a asgi_tools.Response
from asgi_tools import ResponseMiddleware
async def base_app(request, receive, send):
return "Hello World!"
app = ResponseMiddleware(base_app)Router Middleware
Route HTTP requests
from asgi_tools import RouterMiddleware, ResponseMiddleware
async def index_and_default(*args):
return "Hello from Index"
async def page1(*args):
return "Hello from Page1"
async def page2(*args):
return "Hello from Page2"
app = ResponseMiddleware(RouterMiddleware(index_and_default, routes={'/page1': page1, '/page2': page2}))Bug tracker
