I wonder how to pick up the body post request from a fast api server in order to transform this body to making a new body to post another server.

But it does not seem like in express javascript when we could reach the body by using the expression req.body.

I have searched in the documentation but I have not found any example.

Is there any equivalent for this in python fast api ?

EDIT :

here is my current code. After some researchs, it seems that we have to create some class to parse the body but I am not sure…

import json
from random import random

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Body(BaseModel):
    title: str

@app.post("/posts/")
async def posts(body: Body):
    number=random()
    title = body
    posts[number]={
        "msgtype":"PostCreated",
        "data":{
            "id": number,
            "title": title,
        }
    }
    return posts[number]
