## Резюме

С помощью `Query`, `Path` (и других классов, которые мы пока не затронули) вы можете добавлять метаданные и строковую валидацию тем же способом, как и в главе [Query-параметры и валидация строк](query-params-str-validations.md){.internal-link target=_blank}.

А также вы можете добавить валидацию числовых данных:

        // Default constructor
    }

    /**
     * Wraps a query string with wildcard characters to enable partial matching.
     * This method ensures that the query string is surrounded by asterisks (*)
     * to support prefix and suffix matching in search operations.
     *
     * @param query the query string to wrap with wildcards
     * @return the wrapped query string with leading and trailing asterisks
     */

        builder.query("a${value}z")
      }

      override operator fun get(url: HttpUrl): String {
        val query = url.query
        return query!!.substring(1, query.length - 1)
      }
    },

    QUERY_VALUE {
      override fun urlString(value: String): String = "http://example.com/?q=a${value}z"

      override fun encodedValue(url: HttpUrl): String {
        val query = url.encodedQuery

                cb.query().setDescription_Wildcard(dataConfigPager.description);
            } else if (dataConfigPager.description.endsWith("*")) {
                cb.query().setDescription_Prefix(dataConfigPager.description.replaceAll("\\*$", StringUtil.EMPTY));
            } else {
                cb.query().setDescription_MatchPhrase(dataConfigPager.description);
            }
        }

It includes:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

You can import them all directly from `fastapi`:

```python
from fastapi import Body, Cookie, File, Form, Header, Path, Query
```

::: fastapi.Query

::: fastapi.Path

::: fastapi.Body

::: fastapi.Cookie

        final IllegalArgumentException rootCause = new IllegalArgumentException("Invalid character in query");
        final IllegalStateException middleCause = new IllegalStateException("Query parser state error", rootCause);
        final String message = "Query processing failed";

		t.Fatalf("failed to preload and find users: %v", err)
	}

	AssertEqual(t, result, users)
	AssertEqual(t, len(query), 2) // Check preload queries are merged

	if !regexp.MustCompile(`SELECT \* FROM .*tools.* WHERE .*IN.*`).MatchString(query[0]) {
		t.Fatalf("Expected first query to preload manager tools, got: %s", query[0])
	}
