#### 對於有預設值欄位也有實際值的資料 { #data-with-values-for-fields-with-defaults }

但如果你的資料在模型中對於有預設值的欄位也有實際值，例如 ID 為 `bar` 的項目：

```Python hl_lines="3  5"
{
    "name": "Bar",
    "description": "The bartenders",
    "price": 62,
    "tax": 20.2
}
```

它們會被包含在回應中。

#### 與預設值相同的資料 { #data-with-the-same-values-as-the-defaults }

如果資料的值與預設值相同，例如 ID 為 `baz` 的項目：

	if err := tw.writeRawHeader(&tw.blk, int64(len(data)), flag); err != nil {
		return err
	}
	_, err := io.WriteString(tw, data)
	return err
}

// writeRawHeader writes the value of blk, regardless of its value.
// It sets up the Writer such that it can accept a file of the given size.
// If the flag is a special header-only flag, then the size is treated as zero.

    val instant: Instant? = headers.getInstant("")
    val size: Int = headers.size
    val name: String = headers.name(0)
    val value: String = headers.value(0)
    val names: Set<String> = headers.names()
    val values: List<String> = headers.values("")
    val byteCount: Long = headers.byteCount()
    val builder: Headers.Builder = headers.newBuilder()

        synchronized (this.sidCache) {
            try (DcerpcHandle handle = DcerpcHandle.getHandle("ncacn_np:" + server + "[\\PIPE\\lsarpc]", tc)) {
                // NetApp doesn't like the 'generic' access mask values
                try (LsaPolicyHandle policyHandle = new LsaPolicyHandle(handle, null, 0x00000001)) {
                    rpc = new MsrpcQueryInformationPolicy(policyHandle, (short) lsarpc.POLICY_INFO_ACCOUNT_DOMAIN, info);

**FastAPI** はリクエストから自動で変換を行い、パラメータ`item`が特定の内容を受け取り、`user`も同じように特定の内容を受け取ります。

複合データの検証を行い、OpenAPIスキーマや自動ドキュメントのように文書化してくれます。

## ボディ内の単数値 { #singular-values-in-body }

クエリとパスパラメータの追加データを定義するための `Query` と `Path` があるのと同じように、 **FastAPI** は同等の `Body` を提供します。

例えば、前のモデルを拡張して、同じボディに `item` と `user` の他にもう一つのキー `importance` を入れたいと決めることができます。
