## `WSGIMiddleware` Kullanımı

`WSGIMiddleware`'ı projenize dahil edin.

Ardından WSGI (örneğin Flask) uygulamanızı middleware ile sarmalayın.

Son olarak da bir yol altında bağlama işlemini gerçekleştirin.

```

## Kontrol Edelim

from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware

app = FastAPI()

origins = [
    "http://localhost.tiangolo.com",
    "https://localhost.tiangolo.com",
    "http://localhost",
    "http://localhost:8080",
]

app.add_middleware(
    CORSMiddleware,
    allow_origins=origins,
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)


@app.get("/")

## Using `WSGIMiddleware`

You need to import `WSGIMiddleware`.

Then wrap the WSGI (e.g. Flask) app with the middleware.

And then mount that under a path.

```Python hl_lines="2-3  23"
{!../../docs_src/wsgi/tutorial001.py!}
```

## Check it

from fastapi import FastAPI
from fastapi.middleware.wsgi import WSGIMiddleware
from flask import Flask, request
from markupsafe import escape

flask_app = Flask(__name__)


@flask_app.route("/")
def flask_main():
    name = request.args.get("name", "World")
    return f"Hello, {escape(name)} from Flask!"


app = FastAPI()


@app.get("/v2")
def read_main():
    return {"message": "Hello World"}

## `WSGIMiddleware` verwenden

Sie müssen `WSGIMiddleware` importieren.

Wrappen Sie dann die WSGI-Anwendung (z. B. Flask) mit der Middleware.

Und dann mounten Sie das auf einem Pfad.

## Usando o `WSGIMiddleware`

Você precisa importar o `WSGIMiddleware`.

Em seguinda, encapsular a aplicação WSGI (e.g. Flask) com o middleware.

E então **"montar"** em um caminho de rota.
