How can you determine the HTTP request method in an application using FastAPI?

In FastAPI, the HTTP request method is specified using decorators that correspond to the methods: @app.get(), @app.post(), @app.put(), @app.delete(), etc.

Example:

from fastapi import FastAPI, Request

app = FastAPI()

@app.get("/items")
async def read_items():
    return {"method": "GET"}

@app.post("/items")
async def create_item():
    return {"method": "POST"}

# To define a method dynamically inside a handler
@app.api_route("/items", methods=["GET", "POST"])
async def handle_items(request: Request):
    return {"method": request.method}

Thus, the HTTP request method is set via the decorator, and inside the handler, it can be accessed through the Request object.
