Always getting 442 Unprocessable entity #23
Description
I cannot get msgpack-asgi running with FastAPI. Any request with msgpack-bytes is returned with a "422 Unprocessable Entity" error. The following minimal example will show the problem:
from pathlib import Path
import uvicorn
from fastapi import FastAPI
from pydantic import BaseModel
from msgpack_asgi import MessagePackMiddleware
class Foo(BaseModel):
bar: int
app = FastAPI()
app.add_middleware(MessagePackMiddleware)
@app.post("/")
def index(thing: Foo):
return thing
if __name__ == "__main__":
uvicorn.run(f"{Path(__file__).stem}:app", host="0.0.0.0", port=5001, log_level="debug", reload=True)
The data is sent with the following snippet:
import requests
import msgpack
url = "http://127.0.0.1:5001/"
headers = {"content-type": "application/x-msgpack"}
data_raw = {"bar": 23}
data_packed = msgpack.packb(data_raw)
response_json = requests.post(url, json=data_raw)
response_msgpack = requests.post(url, data=data_packed, headers=headers)
Resulting in:
INFO: 127.0.0.1:54682 - "POST / HTTP/1.1" 200 OK
INFO: 127.0.0.1:54684 - "POST / HTTP/1.1" 422 Unprocessable Entity
So the data is accepted as json but refused as msgpack-bytes. May there be an incompatibility with newser versions of FastAPI or pydantic? Or am I just using this completely wrong?
