**FastAPI**は特定の意味づけを強制しません。

ここでの情報は、要件ではなくガイドラインとして提示されます。

例えば、GraphQLを使用する場合、通常は`POST`オペレーションのみを使用してすべてのアクションを実行します。

### Step 4: **path operation 関数**を定義 { #step-4-define-the-path-operation-function }

以下は「**path operation 関数**」です:

* **パス**: は`/`です。
* **オペレーション**: は`get`です。
* **関数**: 「デコレータ」の直下にある関数 (`@app.get("/")`の直下) です。

{* ../../docs_src/first_steps/tutorial001_py310.py hl[7] *}

Bei einigen Anwendungstypen möchten Sie möglicherweise Abhängigkeiten zur gesamten Anwendung hinzufügen.

Ähnlich wie Sie [`dependencies` zu den *Pfadoperation-Dekoratoren* hinzufügen](dependencies-in-path-operation-decorators.md) können, können Sie sie auch zur `FastAPI`-Anwendung hinzufügen.

In diesem Fall werden sie auf alle *Pfadoperationen* in der Anwendung angewendet:

        RuntimeException middleCause = new RuntimeException("LDAP configuration error", innerCause);
        LdapOperationException exception = new LdapOperationException("LDAP operation failed", middleCause);

        assertEquals("LDAP operation failed", exception.getMessage());
        assertEquals(middleCause, exception.getCause());
        assertEquals("LDAP configuration error", exception.getCause().getMessage());

### Tag'lerinizi kullanın { #use-your-tags }

*path operation*'larınızı (ve `APIRouter`'ları) farklı tag'lere atamak için `tags` parametresini kullanın:

{* ../../docs_src/metadata/tutorial004_py310.py hl[21,26] *}

/// info | Bilgi

Tag'ler hakkında daha fazlası için: [Path Operation Configuration](path-operation-configuration.md#tags).

- Additionally in the case of the erasure coded setup `tags.objectLocation` provides per object details about
  - Pool number the object operation was performed on.
  - Set number the object operation was performed on.
  - The list of drives participating in this operation belong to the set.
