### Copyright and License

You can create the *path operations* for that module using `APIRouter`.

### Import `APIRouter` { #import-apirouter }

You import it and create an "instance" the same way you would with the class `FastAPI`:

{* ../../docs_src/bigger_applications/app_an_py310/routers/users.py hl[1,3] title["app/routers/users.py"] *}

        ImmutableSetMultimap.of("of", 'o', "of", 'f', "to", 't', "to", 'o').inverse());
  }

  // Yes, we want to test that inverse() returns the same instance each time that it's called.
  @SuppressWarnings("SelfAssertion")
  public void testInverseMinimizesWork() {
    ImmutableSetMultimap<String, Character> multimap =

            throws InvalidRepositoryException {
        if (layout == null) {
            throw new InvalidRepositoryException(
                    String.format("Cannot find ArtifactRepositoryLayout instance for: %s %s", layoutId, repositoryId),
                    repositoryId);
        }
    }

    public static ArtifactRepository createArtifactRepository(
            String id,

/// note | 技术细节

`FastAPI` 是直接从 `Starlette` 继承的类。

你可以通过 `FastAPI` 使用所有的 [Starlette](https://www.starlette.dev/) 的功能。

///

### 步骤 2：创建一个 `FastAPI`「实例」 { #step-2-create-a-fastapi-instance }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[3] *}

这里的变量 `app` 会是 `FastAPI` 类的一个「实例」。

这个实例将是创建你所有 API 的主要交互对象。

### 步骤 3：创建一个*路径操作* { #step-3-create-a-path-operation }
