// as we cannot call it directly from the test.
    // This requires a package-private or public method in the class under test,
    // or we can just check for the prefix and suffix.
    // For this test, I'll add a helper in the response class to get super.toString()
    // Or, more simply, check the format of the string.

/// info

Notice that `response_description` refers specifically to the response, the `description` refers to the *path operation* in general.

///

/// check

OpenAPI specifies that each *path operation* requires a response description.

So, if you don't provide one, **FastAPI** will automatically generate one of "Successful response".

///

In your top-level application, `app`, mount the sub-application, `subapi`.

In this case, it will be mounted at the path `/subapi`:

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[11, 19] *}

### Check the automatic API docs { #check-the-automatic-api-docs }

Now, run the `fastapi` command:

<div class="termy">

```console
$ fastapi dev

 *       scalability or other performance factors (see the separate "jtreg" tests for a set intended
 *       to check these for the most central aspects of functionality.) So, most tests use the
 *       smallest sensible numbers of threads, collection sizes, etc needed to check basic
 *       conformance.
 *   <li>The test classes currently do not declare inclusion in any particular package to simplify

在這個例子裡，`item_id` 被宣告為 `int`。

/// check

這會在你的函式中提供編輯器支援，包括錯誤檢查、自動完成等。

///

## 資料 <dfn title="也稱為：序列化、解析、封送">轉換</dfn> { #data-conversion }

如果你執行這個範例並在瀏覽器開啟 [http://127.0.0.1:8000/items/3](http://127.0.0.1:8000/items/3)，你會看到這樣的回應：

```JSON
{"item_id":3}
```

/// check

注意你的函式接收（並回傳）的值是 `3`，也就是 Python 的 `int`，而不是字串 `"3"`。

            unverifiedHandshake.peerCertificates,
            address.url.host,
          )
        }
      this.handshake = handshake

      // Check that the certificate pinner is satisfied by the certificates presented.
      certificatePinner.check(address.url.host) {
        handshake.peerCertificates.map { it as X509Certificate }
      }

      // Success! Save the handshake and the ALPN protocol.

The important thing to keep in mind is that the `sub` key should have a unique identifier across the entire application, and it should be a string.

## Check it { #check-it }
