How to pass arguments to function (FastAPI endpoint) loaded from JSON?-CodePudding

I have a FastAPI endpoint which takes up to 70 parameters and they are often added or removed. I have also list of arguments sent to this API stored in JSON format (extracted using json.dumps(locals())), so I can easily reproduce the API call in the future.

I would like to call EP /another-endpoint which is gonna load arguments from JSON and call another EP /my-endpoint, how should I do it?

My code so far

from fastapi import FastAPI
import asyncio

app = FastAPI()
app.mount("/", app)

@app.get('/my-endpoint')
def my_endpoint(
   arg1: int,
   arg2: str,
   ...
   arg70: str
):
  print("Doing some action with those 70 arguments...")
  ...
  return "Some fake response"

# Example arguments in JSON format
arguments_json = {
"arg1": 12,
"arg2": "extract",
....
}

@app.get('/another-endpoint')
async def another_endpoint():
  # I have tried using asyncio since I am calling another async function
  # but this does not work obviously
  response = asyncio.run(my_endpoint(arguments_json))

It does not work, obviously.

CodePudding user response：

you can convert the JSON format arguments into a dictionary, then pass the dictionary as kwargs to the my_endpoint function. Here's an example implementation:

from fastapi import FastAPI
import asyncio

app = FastAPI()
app.mount("/", app)

@app.get('/my-endpoint')
def my_endpoint(
   arg1: int,
   arg2: str,
   ...
   arg70: str
):
  print("Doing some action with those 70 arguments...")
  ...
  return "Some fake response"

# Example arguments in JSON format
arguments_json = {
"arg1": 12,
"arg2": "extract",
....
}

@app.get('/another-endpoint')
async def another_endpoint():
  # Convert the JSON format arguments into a dictionary
  arguments_dict = json.loads(arguments_json)

  # Pass the dictionary as **kwargs to the my_endpoint function
  response = await my_endpoint(**arguments_dict)

  return response
