Request Component

Request Component
The request component holds all the information related to the current request. Json, Forms, Files everything can be accessed through it.
Receiving JSON

from vibora import Vibora, Request

from vibora.responses import JsonResponse

4
app = Vibora()

6
@app.route('/')
7
async def home(request: Request):
8
    values = await request.json()
9
    print(values)
10
    return JsonResponse(values)
11
​
12
app.run()

Note that request.json() is actually a coroutine that needs to be awaited, this design prevents the entire JSON being uploaded in-memory before the route requires it.
Uploaded Files
Uploaded files by multipart forms can be accessed by field name in request.form or through the request.files list. Both methods are co-routines that will consume the request.stream and store the file in-disk if it's too big to keep in-memory.
You can control the memory/disk usage of uploaded files by calling request.load_form(threshold=1 * 1024 * 1024) explicitly, in this case files bigger than 1mb will be flushed to disk.
Please be aware that the form threshold does not passthrough the max_body_size limit so you'll still need to configure your route properly.
Instead of pre-parsing the entire form you could call request.stream_form() and deal with every uploaded field as it arrives by the network. This is good when you don't want files hitting the disk and in some scenarios allows you to waste less memory by doing way more coding yourself.

A request to http://{address}/?name=vibora would return 'Name: vibora'
Raw Stream
Sometimes you need a low-level access to the HTTP request body, request.stream method provides an easy way to consume the stream by ourself.

async def home(request: Request):

    content = await request.stream.read()
8
    return Response(content)

URLs
Ideally you shouldn't need to deal with the URL directly but sometimes that's the only way. The request object carries two properties that can help you:
request.url: Raw URL
request.parsed_url: A parsed URL where you can access the path, host and all URL attributes easily. The URL is parsed by a fast Cython parser so there is no need to you re-invent the wheel.
