例如，上述模型對應的 JSON「`object`」（或 Python `dict`）如下：

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

...由於 `description` 與 `tax` 是選填（預設為 `None`），以下這個 JSON「`object`」也有效：

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

## 將它宣告為參數 { #declare-it-as-a-parameter }

要把它加到你的*路徑操作（path operation）*中，宣告方式與路徑與查詢參數相同：

  }

  @Override
  protected SortedMap<String, Integer> makePopulatedMap() {
    SortedMap<String, Integer> sortedMap = makeEmptyMap();
    sortedMap.put("one", 1);
    sortedMap.put("two", 2);
    sortedMap.put("three", 3);
    return sortedMap;
  }

  @Override
  protected String getKeyNotInPopulatedMap() throws UnsupportedOperationException {
    return "minus one";
  }

  @Override

You will also get autocompletion for the payload to send:

<img src="/img/tutorial/generate-clients/image03.png">

/// tip

Notice the autocompletion for `name` and `price`, that was defined in the FastAPI application, in the `Item` model.

///

You will have inline errors for the data that you send:

<img src="/img/tutorial/generate-clients/image04.png">

func (c *Connection) Subroute(s string) *Subroute {
	if c == nil {
		return nil
	}
	return &Subroute{
		Connection: c,
		route:      s,
		subID:      makeSubHandlerID(0, s),
		trace:      c.trace.subroute(s),
	}
}

// Subroute adds a subroute to the subroute.
// The subroutes are combined with '/'.
func (c *Subroute) Subroute(s string) *Subroute {
	route := strings.Join([]string{c.route, s}, "/")

Wenn Sie also den Artikel mit der ID `foo` bei der *Pfadoperation* anfragen, wird (ohne die Defaultwerte) die Response sein:

```JSON
{
    "name": "Foo",
    "price": 50.2
}
```

 During Maven initialization, Maven tweaks default root logging level to match CLI verbosity choice. Since such feature isn't available
 in SLF4J API, logging implementation specific extensions need to be added into Maven to support these CLI options: see
