## Canceling a decommission

Stop an on-going decommission in progress, mainly used in situations when the load may be too high and you may want to schedule the decommission at a later point in time.

`mc admin decommission cancel` without an argument, lists out any on-going decommission in progress.

```
λ mc admin decommission cancel alias/

            return true; // BAD!!
          }

          @Override
          public String get() {
            return "foo"; // BAD!!
          }

          @Override
          public String get(long time, TimeUnit unit) {
            return "foo"; // BAD!!
          }

          @Override
          public void addListener(Runnable runnable, Executor executor) {
            executor.execute(runnable);
          }

**FastAPI** 为了开发者方便提供了该对象. 但其实它直接来自于 Starlette.

### 在 `response` 的前和后

在任何*路径操作*收到`request`前,可以添加要和请求一起运行的代码.

也可以在*响应*生成但是返回之前添加代码.

例如你可以添加自定义请求头 `X-Process-Time` 包含以秒为单位的接收请求和生成响应的时间:

```Python hl_lines="10  12-13"
{!../../docs_src/middleware/tutorial001.py!}
```

## 其他中间件

            return true; // BAD!!
          }

          @Override
          public String get() {
            return "foo"; // BAD!!
          }

          @Override
          public String get(long time, TimeUnit unit) {
            return "foo"; // BAD!!
          }

          @Override
          public void addListener(Runnable runnable, Executor executor) {
            executor.execute(runnable);
          }

  }
