Це еквівалентно:

Uvicorn та інші сервери підтримують опцію `--reload`, корисну під час розробки.

Опція `--reload` споживає значно більше ресурсів, є менш стабільною тощо.

把输入数据转换为以 JSON 格式存储的数据（比如，使用 NoSQL 数据库时），可以使用 `jsonable_encoder`。例如，把 `datetime` 转换为 `str`。

`PUT` 用于接收替换现有数据的数据。

### 关于替换的警告 { #warning-about-replacing }

用 `PUT` 把数据项 `bar` 更新为以下请求体时：

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

因为其中未包含已存储的属性 `"tax": 20.2`，输入模型会取 `"tax": 10.5` 的默认值。

        });
    }

    @Test
    @DisplayName("Test update on non-existent session")
    public void testUpdateNonExistentSession() throws CIFSException {
        // With enforcement disabled, this should log a warning but not throw
        PreauthIntegrityService lenientService = new PreauthIntegrityService(secureRandom, PreauthIntegrityService.HASH_ALGO_SHA512, false);

        // Should not throw exception

   * time and space.
   *
   * @throws IllegalArgumentException if {@code sequence} contains ill-formed UTF-16 (unpaired
   *     surrogates)
   */
  public static int encodedLength(CharSequence sequence) {
    // Warning to maintainers: this implementation is highly optimized.
    int utf16Length = sequence.length();
    int utf8Length = utf16Length;
    int i = 0;

    // This loop optimizes for pure ASCII.

   * time and space.
   *

   */
  public static int encodedLength(CharSequence sequence) {
    // Warning to maintainers: this implementation is highly optimized.
    int utf16Length = sequence.length();
    int utf8Length = utf16Length;
    int i = 0;

    // This loop optimizes for pure ASCII.

你可以使用 `jsonable_encoder` 將輸入資料轉換為可儲存為 JSON 的資料（例如用於 NoSQL 資料庫）。例如把 `datetime` 轉成 `str`。

`PUT` 用於接收應該取代現有資料的資料。

### 關於取代的警告 { #warning-about-replacing }

這表示，如果你想用 `PUT` 並在 body 中包含以下內容來更新項目 `bar`：

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

        val builtJar = builder.build()
        if (!builder.isOk) {
          builder.getErrors().forEach { task.logger.error("Error: $it") }
          builder.getWarnings().forEach { task.logger.warn("Warning: $it") }
          throw GradleException("Bundle $archiveFileName has errors")
        }

        builtJar.write(archiveFile)
        archiveFile.setLastModified(System.currentTimeMillis())
      }

Cada programa de servidor ASGI alternativo teria um comando semelhante, você pode ler mais na documentação respectiva.

Uvicorn e outros servidores suportam a opção `--reload` que é útil durante o desenvolvimento.

A opção `--reload` consome muito mais recursos, é mais instável, etc.
