### Use the `settings` { #use-the-settings }

Then you can use the new `settings` object in your application:

{* ../../docs_src/settings/tutorial001_py39.py hl[18:20] *}

### Run the server { #run-the-server }

Next, you would run the server passing the configurations as environment variables, for example you could set an `ADMIN_EMAIL` and `APP_NAME` with:

<div class="termy">

        }

        @Test
        @DisplayName("Should have correct values for standard access rights")
        void shouldHaveCorrectStandardAccessRights() {
            // Standard access rights (bits 16-20)
            assertEquals(0x00010000, ACE.DELETE, "DELETE should be 0x00010000");
            assertEquals(0x00020000, ACE.READ_CONTROL, "READ_CONTROL should be 0x00020000");

193C..193F    ; disallowed                             # NA   <reserved-193C>..<reserved-193F>
1940          ; valid                  ;      ; NV8    # 4.0  LIMBU SIGN LOO
1941..1943    ; disallowed                             # NA   <reserved-1941>..<reserved-1943>

  static final double MEGA_STREAM_MEAN = MEGA_STREAM_MAX / 2;
  static final double MEGA_STREAM_POPULATION_VARIANCE =
      (MEGA_STREAM_COUNT - 1) * (MEGA_STREAM_COUNT + 1) / 12.0;

  // Stats instances:

  static final Stats EMPTY_STATS_VARARGS = Stats.of();
  static final Stats EMPTY_STATS_ITERABLE = Stats.of(ImmutableList.<Double>of());

 *  Fix: Reject HTTP/2 data frames if the stream ID is 0.
 *  New: Upgrade to Okio 1.12.0.

     ```xml

     com.squareup.okio:okio:1.12.0
     ```

 *  New: Connection coalescing. OkHttp may reuse HTTP/2 connections across calls that share an IP

		// using a consistent per-value cost for overhead is simpler.
		maxMemoryBytes := 2 * int64(10<<20)
		maxMemoryBytes -= int64(len(name))
		maxMemoryBytes -= mapEntryOverhead
		if maxMemoryBytes < 0 {

        |  -H 'Content-Type: application/octet-stream' \
        |  --data-binary '00010203'
        """.trimMargin(),
      )
  }

  @Test
  fun curlPostWithBinaryBodyOmitted() {
    val binaryData = "1020".decodeHex()
    val body = binaryData.toRequestBody("application/octet-stream".toMediaType())

    val request =
      Request
        .Builder()
        .url("https://api.example.com/upload")

然后，它将转换和验证数据。因此，当您使用该 `settings` 对象时，您将获得您声明的类型的数据（例如 `items_per_user` 将为 `int` 类型）。

### 使用 `settings`

然后，您可以在应用程序中使用新的 `settings` 对象：

{* ../../docs_src/settings/tutorial001.py hl[18:20] *}

### 运行服务器

接下来，您将运行服务器，并将配置作为环境变量传递。例如，您可以设置一个 `ADMIN_EMAIL` 和 `APP_NAME`，如下所示：

<div class="termy">

```console
$ ADMIN_EMAIL="******@****.***" APP_NAME="ChimichangApp"uvicorn main:app

        }

        pos = dateCharacterOffset(s, end + 1, limit, false)
      }

      // Convert two-digit years into four-digit years. 99 becomes 1999, 15 becomes 2015.
      if (year in 70..99) year += 1900
      if (year in 0..69) year += 2000

      // If any partial is omitted or out of range, return -1. The date is impossible. Note that leap
      // seconds are not supported by this syntax.
      require(year >= 1601)
