Nếu bạn sử dụng một tệp `requirements.txt` bạn có thể chỉ định phiên bản với:

```txt
fastapi[standard]==0.112.0
```

Như vậy, bạn sẽ sử dụng chính xác phiên bản `0.112.0`.

Hoặc bạn cũng có thể cố định nó với:

```txt
fastapi[standard]>=0.112.0,<0.113.0
```

El resultado de llamarlo es algo que puede ser codificado con la función estándar de Python <a href="https://docs.python.org/3/library/json.html#json.dumps" class="external-link" target="_blank">`json.dumps()`</a>.

No devuelve un gran `str` que contenga los datos en formato JSON (como una cadena de texto). Devuelve una estructura de datos estándar de Python (por ejemplo, un `dict`) con valores y sub-valores que son todos compatibles con JSON.

        when(mockConfig.isForceUnicode()).thenReturn(false);
        when(mockConfig.getOemEncoding()).thenReturn("ASCII");
    }

    @Test
    @DisplayName("Test constructor with standard path")
    void testConstructorWithStandardPath() {
        // Test standard path without trailing backslash
        trans2FindFirst2 = new Trans2FindFirst2(mockConfig, "\\test\\path", "*.txt", 0x16, 10, 1024);

Durch das Hinzufügen von `standard` installiert und verwendet Uvicorn einige empfohlene zusätzliche Abhängigkeiten.

func ExampleScanner_lines() {
	scanner := bufio.NewScanner(os.Stdin)

		fmt.Fprintln(os.Stderr, "reading standard input:", err)
	}

// Return the most recent call to Scan as a []byte.

Verwenden Sie das `TestClient`-Objekt auf die gleiche Weise wie `httpx`.

Schreiben Sie einfache `assert`-Anweisungen mit den Standard-Python-Ausdrücken, die Sie überprüfen müssen (wiederum, Standard-`pytest`).

Beachten Sie, dass die Testfunktionen normal `def` und nicht `async def` sind.

第一步是安裝 FastAPI。

確保你建立一個[虛擬環境](../virtual-environments.md){.internal-link target=_blank}，啟用它，然後**安裝 FastAPI**：

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note

當你使用 `pip install "fastapi[standard]"` 安裝時，會包含一些預設的可選標準依賴項。

如果你不想包含那些可選的依賴項，你可以使用 `pip install fastapi` 來安裝。
