Example Code

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

app = FastAPI()


@app.get("/")
async def get_item(item_name: str | None = Query(default=None, alias="itemName")):
    return {"message": "Hello World"}

@app.post("/updateFooBarTest")
def update_foo_bar_test(
    foo_bar: str|None = Body(default=None, alias="fooBar", embed=True),
):
    pass

Description

Open the /docs endpoint. In the documentation for GET /, you will see the alias. But in the documentation for POST /updateFooBarTest, you will NOT see the alias.
