 *  Fix: `OkHttpClient` no longer implements `Cloneable`. It never should have; the class is
    immutable. This is left over from OkHttp 2.x (!) when that class was mutable. We're using the
    5.x upgrade as an opportunity to remove very obsolete APIs.
 *  Fix: Recover gracefully when Android's `NativeCrypto` crashes with `"ssl == null"`. This occurs
    when OkHttp retrieves ALPN state on a closed connection.
 *  Upgrade: [Kotlin 1.6.21][kotlin_1_6_21].

* `/items/{item_id}` _yolu_ `item_id` adlı `int` qiyməti almalı olan _yol parametrinə_ sahibdir.
* `/items/{item_id}` _yolunun_ `q` adlı yol parametri var və bu parametr istəyə bağlı olsa da, `str` qiymətini almalıdır.

### İnteraktiv API Sənədləri

在许多情况下，您的应用程序可能需要一些外部设置或配置，例如密钥、数据库凭据、电子邮件服务的凭据等等。

这些设置中的大多数是可变的（可以更改的），比如数据库的 URL。而且许多设置可能是敏感的，比如密钥。

因此，通常会将它们提供为由应用程序读取的环境变量。

## 环境变量

/// tip

如果您已经知道什么是"环境变量"以及如何使用它们，请随意跳到下面的下一节。

///

环境变量（也称为"env var"）是一种存在于 Python 代码之外、存在于操作系统中的变量，可以被您的 Python 代码（或其他程序）读取。

您可以在 shell 中创建和使用环境变量，而无需使用 Python：

//// tab | Linux、macOS、Windows Bash

<div class="termy">

```console
// 您可以创建一个名为 MY_NAME 的环境变量

  public void testNewSetFromMapIllegal() {
    Map<Integer, Boolean> map = new LinkedHashMap<>();
    map.put(2, true);
    assertThrows(IllegalArgumentException.class, () -> Sets.newSetFromMap(map));
  }

  /** The 0-ary cartesian product is a single empty list. */
  public void testCartesianProduct_zeroary() {
    assertThat(cartesianProduct()).containsExactly(list());
  }

						{PrimaryKey: "ID", PrimarySchema: "Country", ForeignKey: "CountryID", ForeignSchema: "Org"},
					},
				},
			},
		},
	})
}

func TestVariableRelation(t *testing.T) {
	var result struct {
		User
	}

	checkStructRelation(t, &result, Relation{
		Name: "Account", Type: schema.HasOne, Schema: "", FieldSchema: "Account",
		References: []Reference{

     * handling not just {@code Iterable<S>} instances, but also any {@code

     * that it doesn't justify making everyone else deal with the very ugly

    return new LexicographicalOrdering<S>(this);
  }

  // Regular instance methods
