    causing some `Authenticator` calls to see a null route when non-null was expected.

 *  Fix: Use the correct key size in the name of `TLS_AES_128_CCM_8_SHA256` which is a TLS 1.3
    cipher suite. We accidentally specified a key size of 256, preventing that cipher suite from
    being selected for any TLS handshakes. We didn't notice because this cipher suite isn't

你希望将与用户相关的*路径操作*与其他代码分开，以使其井井有条。

但它仍然是同一 **FastAPI** 应用程序/web API 的一部分（它是同一「Python 包」的一部分）。

你可以使用 `APIRouter` 为该模块创建*路径操作*。

### 导入 `APIRouter`

你可以导入它并通过与 `FastAPI` 类相同的方式创建一个「实例」：

```Python hl_lines="1  3" title="app/routers/users.py"
{!../../docs_src/bigger_applications/app/routers/users.py!}
```

### 使用 `APIRouter` 的*路径操作*

然后你可以使用它来声明*路径操作*。

使用方式与 `FastAPI` 类相同：

    // Skipping 20
    assertEquals((Integer) 11, it.next());
    // Not skipping 400, because it moved back down
    assertEquals((Integer) 400, it.next());
    assertEquals((Integer) 13, it.next());
    assertEquals((Integer) 200, it.next());
    assertEquals((Integer) 300, it.next());
    // Last from forgetMeNot.
    assertEquals((Integer) 500, it.next());
  }

	return
}

// Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
func (z *BatchKeyRotateFilter) Msgsize() (s int) {
	s = 1 + 10 + msgp.DurationSize + 10 + msgp.DurationSize + 13 + msgp.TimeSize + 14 + msgp.TimeSize + 5 + msgp.ArrayHeaderSize
	for za0001 := range z.Tags {
		s += z.Tags[za0001].Msgsize()
	}
	s += 9 + msgp.ArrayHeaderSize
	for za0002 := range z.Metadata {

}

func (r13 *rot13Reader) Read(p []byte) (int, error) {
	n, err := r13.r.Read(p)
	for i := 0; i < n; i++ {
		c := p[i] | 0x20 // lowercase byte
		if 'a' <= c && c <= 'm' {
			p[i] += 13
		} else if 'n' <= c && c <= 'z' {
			p[i] -= 13
		}
	}
	return n, err
}

// Call ReadByte to accumulate the text of a file
func readBytes(buf *Reader) string {
	var b [1000]byte
	nb := 0
	for {
		c, err := buf.ReadByte()
