Query parameters - Dictionary support?

Description

While am using this feature, I have this requirement where I need a parameter to be a Dictionary(key values list) for ‘GET’ query parameters. Currently the GET operation seem to support only the following parameter types

• String
• Int
• Enum
• List[str] or List[int]
• Kwargs(variable number of args in dictionary form)

Do you have any recommendations?. One suggestion I got is to use POST instead of GET and achieve the flexible query. Is that a good idea?

I guess you can use Depends to achieve it:

import json
from typing import List
from fastapi import FastAPI, Query, Depends


app = FastAPI(debug=True)


def location_dict(locations: List[str] = Query(...)):
    return list(map(json.loads, locations))


@app.get("/test")
def operation(locations: list = Depends(location_dict)):
    return locations

Looking at starlette documentation today, I found that you can get a dict of query params by using request like this

`from fastapi import FastAPI, Request from pydantic import BaseModel from typing import Optional from datetime import date

app = FastAPI()

class Query(BaseModel): msg: Optional[str] = None page: Optional[int] = None only_one: bool when: date

@app.get(‘/’) async def home(req: Request, only_one: bool, when: date, msg: str = None, page: int = None): query = Query(**req.query_params).dict(exclude_unset=True) return query`
