How do I handle multiple slashes in the URL path leading, mid-path or trailing, similar to non strict slashes in Flask.

First check

• I added a very descriptive title to this issue.
• I used the GitHub search to find a similar issue and didn’t find it.
• I searched the FastAPI documentation, with the integrated search.
• I already searched in Google “How to X in FastAPI” and didn’t find any information.
• I already read and followed all the tutorial in the docs and didn’t find an answer.
• I already checked if it is not related to FastAPI but to Pydantic.
• I already checked if it is not related to FastAPI but to Swagger UI.
• I already checked if it is not related to FastAPI but to ReDoc.
• After submitting this, I commit to one of:
  • Read open issues with questions until I find 2 issues where I can help someone and add a comment to help there.
  • I already hit the “watch” button in this repository to receive notifications and I commit to help at least 2 people that ask questions in the future.
  • Implement a Pull Request for a confirmed bug.

Example

Here’s a self-contained, minimal, reproducible, example with my use case:

from fastapi import FastAPI

app = FastAPI()


@app.get("/hello/x")
def read_root():
    return {"Hello": "World"}

Description

curl http://localhost:8000/hello/x --> is OK
curl http://localhost:8000///hello///x --> throws 404

from fastapi import FastAPI

from someplace import HttpUrlRedirectMiddleware

app = FastAPI()
app.add_middleware(HttpUrlRedirectMiddleware)
