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。

所有相同的 `parameters`、`responses`、`dependencies`、`tags` 等等。

/// tip

在此示例中，该变量被命名为 `router`，但你可以根据你的想法自由命名。

///

我们将在主 `FastAPI` 应用中包含该 `APIRouter`，但首先，让我们来看看依赖项和另一个 `APIRouter`。

## 依赖项

### Sub-dependencies

linked without the Library, or if the work is itself a library.  The
threshold for this to be true is not precisely defined by law.

  If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative

## Containers and Processes

A **container image** normally includes in its metadata the default program or command that should be run when the **container** is started and the parameters to be passed to that program. Very similar to what would be if it was in the command line.

When a **container** is started, it will run that command/program (although you can override it and make it run a different command/program).

          if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

          System.out.println(response.body().string());
        }
      }
    ```

### Posting form parameters ([.kt][PostFormKotlin], [.java][PostFormJava])

Use `FormBody.Builder` to build a request body that works like an HTML `<form>` tag. Names and values will be encoded using an HTML-compatible form URL encoding.

   * strong values, and no automatic eviction of any kind.
   *
   * <p>Note that while this return type is {@code CacheBuilder<Object, Object>}, type parameters on
   * the {@link #build} methods allow you to create a cache of any key and value type desired.
