How could I send an array of list as query parameters via POST method?

I have to send a list or array as parameters with POST method, like this:

@app.post('endpoint')

async def feedback(feed: List[int])

I expect to be able to send parameters of a list of integer, and return the response.

However, in the UI document, the endpoint couldn’t receive request parameters, instead only showing return 0.

I’d looked for request body, and tried to do something like this:

class Item(BaseModel):
  feedback: int

async def feedback(feed: List[Item])

But that returns this: feedback: 0 and I still could not send parameters of a list.

How could I fulfill this task?

Sorry for the long delay! 🙈 I wanted to personally address each issue/PR and they piled up through time, but now I’m checking each one in order.

Unfortunately, that’s not possible.

But there is two way. One is using JSON body, and the other is that you need to parse a parameter yourself.

The former is a good way and recommended. The latter looks ugly and not a good way.

@app.post("/endpoint")
async def feedback(feed: List[str] = Query(...)):
    feed_list = [int(_) for _ in feed.split(",")]
    return feed_list

When using the latter, it can’t appear your intention in docs. I hope it helps.

I understand, I may have to create an JSON file containing the list of values, and attach in the request body. Thank you!
