# GraphQL { #graphql }

**FastAPI**, **ASGI** standardını temel aldığı için ASGI ile uyumlu herhangi bir **GraphQL** kütüphanesini entegre etmek oldukça kolaydır.

Aynı uygulama içinde normal FastAPI *path operation*'larını GraphQL ile birlikte kullanabilirsiniz.

/// tip | İpucu

**GraphQL** bazı çok özel kullanım senaryolarını çözer.

Yaygın **web API**'lerle karşılaştırıldığında **avantajları** ve **dezavantajları** vardır.

# Exceptions - `HTTPException` and `WebSocketException`

These are the exceptions that you can raise to show errors to the client.

When you raise an exception, as would happen with normal Python, the rest of the execution is aborted. This way you can raise these exceptions from anywhere in the code to abort a request and show the error to the client.

You can use:

* `HTTPException`
* `WebSocketException`

            "input": "plumbus",
        }
    ]
}

## Desactivar la conversión de guiones bajos { #disable-convert-underscores }

De la misma forma que con los parámetros de header normales, cuando tienes caracteres de guion bajo en los nombres de los parámetros, se **convierten automáticamente en guiones**.

		ACB_PWNOTREQ               = 0x00000004, /* 1 = User password not required */
		ACB_TEMPDUP                = 0x00000008, /* 1 = Temporary duplicate account */
		ACB_NORMAL                 = 0x00000010, /* 1 = Normal user account */
		ACB_MNS                    = 0x00000020, /* 1 = MNS logon user account */
		ACB_DOMTRUST               = 0x00000040, /* 1 = Interdomain trust account */

@rem Set local scope for the variables with windows NT shell
if "%OS%"=="Windows_NT" setlocal

set DIRNAME=%~dp0
if "%DIRNAME%"=="" set DIRNAME=.
@rem This is normally unused
set APP_BASE_NAME=%~n0
set APP_HOME=%DIRNAME%

@rem Resolve any "." and ".." in APP_HOME to make it shorter.
for %%i in ("%APP_HOME%") do set APP_HOME=%%~fi

Base64 puede codificar datos binarios en strings, pero para hacerlo necesita usar más caracteres que los datos binarios originales, así que normalmente sería menos eficiente que los archivos normales.

Usa base64 solo si definitivamente necesitas incluir datos binarios en JSON y no puedes usar archivos para eso.

## Pydantic `bytes` { #pydantic-bytes }

### Nicht-async *Pfadoperation-Funktionen* { #non-async-path-operation-functions }

Sie können auch normale `def`-Funktionen (ohne `async`) verwenden und `yield` auf die gleiche Weise einsetzen.

FastAPI stellt sicher, dass sie korrekt ausgeführt werden, sodass der Event Loop nicht blockiert wird.

- Follow the existing Japanese style: short, descriptive headings (often noun phrases), e.g. 「チェック」.
- Do not add a trailing period at the end of headings.

### Quotes

- Prefer Japanese corner brackets 「」 in normal prose when quoting a term.
- Do not change quotes inside inline code, code blocks, URLs, or file paths.

### Ellipsis

- Keep ellipsis style consistent with existing Japanese docs (commonly `...`).

    protected final ClassWorld classWorld;
    protected final boolean classWorldManaged;

    /**
     * Ctor that creates "managed" ClassWorld. This constructor is not used in "normal" circumstances.
     */
    public ClingSupport() {
        this(new ClassWorld(CORE_CLASS_REALM_ID, Thread.currentThread().getContextClassLoader()), true);
    }

    /**

Also, HTTP headers are case-insensitive, so, you can declare them with standard Python style (also known as "snake_case").

So, you can use `user_agent` as you normally would in Python code, instead of needing to capitalize the first letters as `User_Agent` or something similar.
