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

### *Path operations* with `APIRouter`

And then you use it to declare your *path operations*.

Use it the same way you would use the `FastAPI` class:

```Python hl_lines="6  11  16" title="app/routers/users.py"
{!../../../docs_src/bigger_applications/app/routers/users.py!}
```

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：

```Python hl_lines="6  11  16" title="app/routers/users.py"
{!../../../docs_src/bigger_applications/app/routers/users.py!}
```

你可以将 `APIRouter` 视为一个「迷你 `FastAPI`」类。

所有相同的选项都得到支持。

            handler.formatter = MessageFormatter
            activeLogger.addHandler(handler)
          }
        }
      }
    }

    fun getLogger(name: String): Logger {
      val logger = Logger.getLogger(name)
      activeLoggers.add(logger)
      return logger
    }
  }

    val suspiciousDaemons = ConcurrentHashMap<String, MutableSet<String>>()

    private
    val daemonPids = ConcurrentHashMap.newKeySet<String>()

    private
    val logger = Logging.getLogger(DaemonTracker::class.java)

    override fun close() {
        logger.lifecycle("Cleaning up daemons...")
        cleanUpDaemons()
    }

    fun newDaemonListener() =
        object : TestListener {

      currentThread = Thread.currentThread()
      logger.addHandler(loggerHandler)
    }

    override fun secureConnectEnd(
      call: Call,
      handshake: Handshake?,
    ) {
      logger.removeHandler(loggerHandler)
    }

    override fun callEnd(call: Call) {
      // Cleanup log handler if failed.
      logger.removeHandler(loggerHandler)
    }

    portField = serverSocket!!.localPort

    taskRunner.newQueue().execute("MockWebServer $portField", cancelable = false) {
      try {
        logger.fine("$this starting to accept connections")
        acceptConnections()
      } catch (e: Throwable) {
        logger.log(Level.WARNING, "$this failed unexpectedly", e)
      }

      // Release all sockets and all threads, even if any close fails.
