asgi-request-id
This was developed at GRID for use with our python backend services and intended to make it easier to log/generate request IDs.
installation
pip install asgi-request-id
usage
import logging
import uvicorn
from starlette.applications import Starlette
from starlette.responses import PlainTextResponse
from asgi_request_id import RequestIDMiddleware, get_request_id
logger = logging.getLogger(__name__)
app = Starlette()
@app.route("/")
def homepage(request):
logger.info(f"Request ID: {get_request_id()}")
return PlainTextResponse("hello world")
app.add_middleware(
RequestIDMiddleware,
incoming_request_id_header="x-amzn-trace-id",
prefix="myapp-",
)
if __name__ == "__main__":
uvicorn.run(app)The package will do the following:
Search for an incoming request identifier and use it as the request id if found. If it is not found, an unique request id with an optional prefix is generated.
The request id is stored in a context variable and made available via
get_request_id
Finally, it is set as the request_id response header.
