#### The time to answer helps the attackers { #the-time-to-answer-helps-the-attackers }

At that point, by noticing that the server took some microseconds longer to send the "Incorrect username or password" response, the attackers will know that they got _something_ right, some of the initial letters were right.

## Overriding dependencies during testing { #overriding-dependencies-during-testing }

There are some scenarios where you might want to override a dependency during testing.

You don't want the original dependency to run (nor any of the sub-dependencies it might have).

///

## Ordonnez les paramètres comme vous le souhaitez

/// tip

Ce n'est probablement pas aussi important ou nécessaire si vous utilisez `Annotated`.

///

Disons que vous voulez déclarer le paramètre de requête `q` comme un `str` requis.

</div>

... qui comprend également `uvicorn`, que vous pouvez utiliser comme serveur pour exécuter votre code.

/// note

Vous pouvez également l'installer pièce par pièce.

C'est ce que vous feriez probablement une fois que vous voudrez déployer votre application en production :

```
pip install fastapi
```

Installez également `uvicorn` pour qu'il fonctionne comme serveur :

```
pip install uvicorn
```

        netdfs.DfsInfo1 info1 = new netdfs.DfsInfo1();
        info1.entry_path = "test_path";

        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        // Create buffer for encoding - initially allocate some space
        byte[] encodeBuffer = new byte[1024];
        NdrBuffer dst = new NdrBuffer(encodeBuffer, 0);
        info1.encode(dst);

        ByteArrayInputStream bis = new ByteArrayInputStream(bos.toByteArray());

</div>

## Forbid Extra Headers { #forbid-extra-headers }

In some special use cases (probably not very common), you might want to **restrict** the headers that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/header_param_models/tutorial002_an_py310.py hl[10] *}

If a client tries to send some **extra headers**, they will receive an **error** response.

   *
   * @return the next two bytes of the input stream, interpreted as an unsigned 16-bit integer in
   *     little-endian byte order
   * @throws IOException if an I/O error occurs
   */
  @CanIgnoreReturnValue // to skip some bytes
  @Override
  public int readUnsignedShort() throws IOException {
    byte b1 = readAndCheckByte();
    byte b2 = readAndCheckByte();

    return Ints.fromBytes((byte) 0, (byte) 0, b2, b1);
  }

In this case, it would be better to get **one extra server** and run some processes on it so that they all have **enough RAM and CPU time**.

import (
	"archive/tar"
	"bytes"
	"fmt"
	"io"
	"log"
	"os"
)

func Example_minimal() {
	// Create and add some files to the archive.
	var buf bytes.Buffer
	tw := tar.NewWriter(&buf)
	var files = []struct {
		Name, Body string
	}{
		{"readme.txt", "This archive contains some text files."},
		{"gopher.txt", "Gopher names:\nGeorge\nGeoffrey\nGonzo"},
		{"todo.txt", "Get animal handling license."},
	}
