Example Code

from fastapi import FastAPI

app = FastAPI()


@app.post("/")
def read_root(image_url: Optional[str] = Query('', alias="image_url"), file: UploadFile = File(Required, alias="file")):
    return RedirectResponse("/another")

@app.post("/another")
def read_another_root(image_url: Optional[str] = Query('', alias="image_url"), file: UploadFile = File(Required, alias="file")):
    return {"Hello": "World"}

Description

When the server is requested at / in post method, I want to redirect the /another in post method with same body and multipart file. How can I pass the original body and multipart file into the redirection endpoint?

What is the usecase? You could just add multiple paths for the same endpoint

from fastapi import FastAPI

app = FastAPI()

@app.post("/")
@app.post("/another")
def read_another_root(image_url: Optional[str] = Query('', alias="image_url"), file: UploadFile = File(Required, alias="file")):
    return {"Hello": "World"}

I don’t think it is supported in the same way a GET is as the user would need to confirm the redirection

User (Data) -> Server 1 Server 1 (Redirect to Server 2) -> User User - who the heck is server 2… 😃

Since you are not redirecting to another server, you can just call the function directly

from fastapi import FastAPI

app = FastAPI()


@app.post("/")
def read_another_root(demo: str):
    if demo.startswith("a"):
        return do_a(demo)
    return do_b(demo)


@app.post("/a")
def do_a(demo: str):
    return {"answer": "a"}


@app.post("/b")
def do_b(demo: str):
    return {"answer": "b"}
