List as query param

Here I’m creating operation , and I want to pass to it multiple query parameters like

/test?query=1&query=2&query=3

this is my code:

from typing import List
from fastapi import FastAPI, Query, Body

app = FastAPI(debug=True)


@app.get("/test")
def check(query: List[int]):
    return query

Expected behavior

in docs I should see this param if I call it should accept GET params

Screenshots

No parameters in docs:

when I try to call it - got an error that body is not supplied:

Environment

• OS:macOS
• FastAPI 0.54.1
• Python 3.7.4

This works:

from typing import List
from fastapi import FastAPI, Query

app = FastAPI()


@app.get("/test")
async def test(query: List[int] = Query(...)) -> List[int]:

    return query

All the best 😃

This works: async def test(query: List[int] = Query(…)) -> List[int]: All the best 😃

Yes, it works, but my guess is - either FastAPI should raise some validation error or it should treat default params as Query (like it does for string, int annotations)
