Matchers

Method

match_method(method)
from jj.http.methods import ANY, GET, POST

@jj.match_method(GET)
async def handler(request):
    return jj.Response(body="Method: " + request.method)

Path

match_path(path)
@jj.match_path("/users")
async def handler(request):
    return jj.Response(body="Path: " + request.path)

Params

match_param(name, val)
@jj.match_param("locale", "en_US")
async def handler(request):
    locales = request.params.getall('locale')
    return jj.Response(body="Locales: " + ",".join(locales))
match_params(params)
@jj.match_params({"locale": "en_US", "timezone": "UTC"})
async def handler(request):
    # Literal String Interpolation (PEP 498)
    return jj.Response(body=f"Params: {request.params}")

Headers

match_header(name, val)
@jj.match_header("X-Forwarded-Proto", "https")
async def handler(request):
    proto = request.headers.getone("X-Forwarded-Proto")
    return jj.Response(body="Proto: " + proto)
match_headers(headers)
@jj.match_headers({
    "x-user-id": "1432",
    "x-client-id": "iphone",
})
async def handler(request):
    return jj.Response(body=f"Headers: {request.headers}")

Combining Matchers

match_any(matchers)
from jj.http import PATCH, PUT

@jj.match_any([
    jj.match_method(PUT),
    jj.match_method(PATCH),
])
async def handler(request):
    return jj.Response(body="200 OK")
match_all(matchers)
@jj.match_all([
    jj.match_method("*"),
    jj.match_path("/"),
    jj.match_params({"locale": "en_US"}),
    jj.match_headers({"x-request-id": "0fefbf48"}),
])
async def handler(request):
    return jj.Response(body="200 OK")
match(method, path, params, headers)
@jj.match("*", "/", {"locale": "en_US"}, {"x-request-id": "0fefbf48"})
async def handler(request):
    return jj.Response(body="200 OK")
