...因为路径中没有必选参数 `needy`，返回的响应中会显示如下错误信息：

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

`needy` 是必选参数，因此要在 URL 中设置值：

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

...这样就正常了：

```JSON

    "item_id": "foo-item",
