response = requests.get("http://example.com/some/url")
```

The FastAPI counterpart API *path operation* could look like:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

See the similarities in `requests.get(...)` and `@app.get(...)`.

        {"url": "https://prod.example.com", "description": "Production environment"},

    root_path="/api/v1",
)


@app.get("/app")
def read_main(request: Request):

```Python
response = requests.get("http://example.com/some/url")
```

对应地，FastAPI 的 API 路径操作可能看起来是这样的：

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

可以看到 `requests.get(...)` 与 `@app.get(...)` 的相似之处。

Response şöyle bir şey olur:
