If you click the lock icon and logout, and then try the same operation again, you will get an HTTP 401 error of:

```JSON
{
  "detail": "Not authenticated"
}
```

### Inactive user { #inactive-user }

Now try with an inactive user, authenticate with:

User: `alice`

Password: `secret2`

And try to use the operation `GET` with the path `/users/me`.

In this case, this `__call__` is what **FastAPI** will use to check for additional parameters and sub-dependencies, and this is what will be called to pass a value to the parameter in your *path operation function* later.

## Parameterize the instance { #parameterize-the-instance }

And now, we can use `__init__` to declare the parameters of the instance that we can use to "parameterize" the dependency:

   *     using it, it is probably not doing what you want.

## Özet { #recap }

Bir request yalnızca tek bir body içerebilse de, *path operation function*'ınıza birden fazla body parametresi ekleyebilirsiniz.

Ancak **FastAPI** bunu yönetir; fonksiyonunuza doğru veriyi verir ve *path operation* içinde doğru şemayı validate edip dokümante eder.

Ayrıca tekil değerlerin body'nin bir parçası olarak alınmasını da tanımlayabilirsiniz.

* `close()`: Closes the file.

As all these methods are `async` methods, you need to "await" them.

For example, inside of an `async` *path operation function* you can get the contents with:

```Python
contents = await myfile.read()
```

If you are inside of a normal `def` *path operation function*, you can access the `UploadFile.file` directly, for example:

```Python
contents = myfile.file.read()
```

which in turn are made up of memory operations.
</p>

<p>
A <i>memory operation</i> is modeled by four details:
</p>
<ul>
	<li>its kind, indicating whether it is an ordinary data read, an ordinary data write,
    or a <i>synchronizing operation</i> such as an atomic data access,
	a mutex operation, or a channel operation,</li>
	<li>its location in the program,</li>

            this.result = buf.dec_ndr_long();
        } else { /* Bind_ack or Response */
            decode_out(buf);
        }
    }

    /**
     * Get the operation number for this DCERPC message.
     * @return the operation number
     */
    public abstract int getOpnum();

    /**
     * Encode the input parameters for this DCERPC message.
     * @param buf the buffer to encode into

## Additional Response with `model` { #additional-response-with-model }

You can pass to your *path operation decorators* a parameter `responses`.

It receives a `dict`: the keys are status codes for each response (like `200`), and the values are other `dict`s with the information for each of them.
