<mxCell id="62" value="&lt;font face=&quot;Roboto&quot; data-font-src=&quot;https://fonts.googleapis.com/css?family=Roboto&quot; style=&quot;font-size: 24px&quot;&gt;FastAPI&lt;/font&gt;&lt;font face=&quot;Roboto&quot; data-font-src=&quot;https://fonts.googleapis.com/css?family=Roboto&quot; style=&quot;font-size: 24px ; font-weight: normal&quot;&gt; app for: someapp.example.com&lt;/font&gt;" style="rounded=0;whiteSpace=wrap;html=1;fontStyle=1;strokeWidth=4;fillColor=#dae8fc;s...

                <mxCell id="62" value="&lt;font face=&quot;Roboto&quot; data-font-src=&quot;https://fonts.googleapis.com/css?family=Roboto&quot; style=&quot;font-size: 24px&quot;&gt;FastAPI&lt;/font&gt;&lt;font face=&quot;Roboto&quot; data-font-src=&quot;https://fonts.googleapis.com/css?family=Roboto&quot; style=&quot;font-size: 24px ; font-weight: normal&quot;&gt; app for: someapp.example.com&lt;/font&gt;" style="rounded=0;whiteSpace=wrap;html=1;fontStyle=1;strokeWidth=4;fillColor=#dae8fc;s...

                <mxCell id="62" value="&lt;font face=&quot;Roboto&quot; data-font-src=&quot;https://fonts.googleapis.com/css?family=Roboto&quot; style=&quot;font-size: 24px&quot;&gt;FastAPI&lt;/font&gt;&lt;font face=&quot;Roboto&quot; data-font-src=&quot;https://fonts.googleapis.com/css?family=Roboto&quot; style=&quot;font-size: 24px ; font-weight: normal&quot;&gt; app for: someapp.example.com&lt;/font&gt;" style="rounded=0;whiteSpace=wrap;html=1;fontStyle=1;strokeWidth=4;fillColor=#dae8fc;s...

                    <mxGeometry x="330" y="680" width="170" height="120" as="geometry"/>
                </mxCell>

Теперь попробуйте отправить недействительный элемент, например:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

Вы получите ответ о том, что данные недействительны, содержащий следующее тело:

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",
        "size"
      ],
      "msg": "value is not a valid integer",
      "type": "type_error.integer"
    }

## `GZipMiddleware`

处理 `Accept-Encoding` 请求头中包含 `gzip` 请求的 GZip 响应。

中间件会处理标准响应与流响应。

```Python hl_lines="2  6"
{!../../../docs_src/advanced_middleware/tutorial003.py!}
```

支持以下参数：

* `minimum_size` - 小于最小字节的响应不使用 GZip。 默认值是 `500`。

## 其它中间件

除了上述中间件外，FastAPI 还支持其它ASGI 中间件。

例如：

* <a href="https://docs.sentry.io/platforms/python/asgi/" class="external-link" target="_blank">Sentry</a>

                </mxCell>
                <mxCell id="101" value="&lt;span style=&quot;font-family: &amp;#34;roboto&amp;#34; ; font-size: 24px&quot;&gt;IP:&lt;/span&gt;&lt;br style=&quot;font-family: &amp;#34;roboto&amp;#34;&quot;&gt;&lt;span style=&quot;font-family: &amp;#34;roboto&amp;#34; ; font-size: 24px&quot;&gt;123.124.125.126&lt;/span&gt;" style="shape=hexagon;perimeter=hexagonPerimeter2;whiteSpace=wrap;html=1;fixedSize=1;strokeWidth=3;" parent="1" vertex="1">

                <mxCell id="42" value="&lt;font face=&quot;Roboto&quot; data-font-src=&quot;https://fonts.googleapis.com/css?family=Roboto&quot;&gt;&lt;span style=&quot;font-size: 24px&quot;&gt;IP:&lt;/span&gt;&lt;br&gt;&lt;span style=&quot;font-size: 24px&quot;&gt;123.124.125.126&lt;/span&gt;&lt;br&gt;&lt;/font&gt;" style="rounded=0;whiteSpace=wrap;html=1;strokeColor=#000000;strokeWidth=3;" parent="1" vertex="1">

                </mxCell>

```

Now try sending an invalid item like:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

You will receive a response telling you that the data is invalid containing the received body:

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",
        "size"
      ],
      "msg": "value is not a valid integer",
      "type": "type_error.integer"
    }
