POST to external url with FastAPI

Question

I've been trying to figure out how to properly do a POST with FastAPI.

I'm currently doing a POST with python's "requests module" and passing some json data as shown below:

import requests
from fastapi import FastAPI

json_data = {"user" : MrMinty, "pass" : "password"} #json data
endpoint = "https://www.testsite.com/api/account_name/?access_token=1234567890" #endpoint
print(requests.post(endpoint, json=json_data). content)

I don't understand how to do the same POST using just FastAPI's functions, and reading the response.

What do you mean by "do the same POST using just FastAPI's functions? FastAPI is not an API client, is an API server - it does not do outgoing requests. Use `requests`, `httpx` or `urllib3` for that. — MatsLindh, Mar 24 '22 at 20:58

I just wanted to make sure that there wasn't a way to make outgoing requests --as I was over the FastAPI's callback documentation https://fastapi.tiangolo.com/advanced/openapi-callbacks/ — MrMinty, Mar 24 '22 at 21:06

The module request is not a FastAPI function, but is everything you need, first you need to have your FastAPI server running, either in your computer or in a external server that you have access.

Then you need to know the IP or domain of your server, and then you make the request:

import requests
some_info = {'info':'some_info'}
head = 'http://192.168.0.8:8000' #IP and port of your server 
# maybe in your case the ip is the localhost 
requests.post(f'{head}/send_some_info', data=json.dumps(tablea))
# "send_some_info" is the address of your function in fast api

Your FastApI script would look like this, and should be running while you make your request:

from fastapi import FastAPI
app = FastAPI()

@app.post("/send_some_info")
async def test_function(dict: dict[str, str]):
    # do something
    return 'Success'
