## `examples` у JSON-схемі — OpenAPI

При використанні будь-кого з наступного:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

Ви також можете задати набір `examples` з додатковою інформацією, яка буде додана до їхніх **JSON-схем** у **OpenAPI**.

### `Body` з `examples`

Там вы можете задать:

* "Item ID", используемый в пути.
* "Token", используемый как query-параметр.

/// tip | Подсказка

Обратите внимание, что query-параметр `token` будет обработан в зависимости.

///

Теперь вы можете подключиться к веб-сокету и начинать отправку и получение сообщений:

    for query in \
      "IF DB_ID('gorm') IS NULL CREATE DATABASE gorm" \
      "IF SUSER_ID (N'gorm') IS NULL CREATE LOGIN gorm WITH PASSWORD = 'LoremIpsum86';" \
      "IF USER_ID (N'gorm') IS NULL CREATE USER gorm FROM LOGIN gorm; ALTER SERVER ROLE sysadmin ADD MEMBER [gorm];"
    do
      SQLCMDPASSWORD=LoremIpsum86 sqlcmd -U sa -S localhost:9930 -Q "$query" > /dev/null || true
    done
  else

from typing import Annotated

from fastapi import Depends, FastAPI, HTTPException, Query
from sqlmodel import Field, Session, SQLModel, create_engine, select


class Hero(SQLModel, table=True):
    id: int | None = Field(default=None, primary_key=True)
    name: str = Field(index=True)
    age: int | None = Field(default=None, index=True)
    secret_name: str


sqlite_file_name = "database.db"
sqlite_url = f"sqlite:///{sqlite_file_name}"

                }
            }
        },
        "components": {
            "securitySchemes": {
                "APIKeyQuery": {"type": "apiKey", "name": "key", "in": "query"}
            }
        },

```console
$ pip install python-multipart
```

///

## `Form` 임포트하기

`fastapi`에서 `Form`을 임포트합니다:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[3] *}

## `Form` 매개변수 정의하기

`Body` 또는 `Query`와 동일한 방식으로 폼 매개변수를 만듭니다:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[9] *}

예를 들어, OAuth2 사양을 사용할 수 있는 방법 중 하나("패스워드 플로우"라고 함)로 `username`과 `password`를 폼 필드로 보내야 합니다.

func (w *nullResponseWriter) WriteHeader(statusCode int) {
}

func (w *nullResponseWriter) Flush() {
}

func benchmarkSelect(b *testing.B, count int, query string) {
	requestXML := []byte(`
<?xml version="1.0" encoding="UTF-8"?>
<SelectObjectContentRequest>
    <Expression>` + query + `</Expression>
    <ExpressionType>SQL</ExpressionType>
    <InputSerialization>
        <CompressionType>NONE</CompressionType>
        <CSV>

There you can set:

* The "Item ID", used in the path.
* The "Token" used as a query parameter.

/// tip

Notice that the query `token` will be handled by a dependency.

///

With that you can connect the WebSocket and then send and receive messages:
