* `allow_origins` - A list of origins that should be permitted to make cross-origin requests. E.g. `['https://example.org', 'https://www.example.org']`. You can use `['*']` to allow any origin.
* `allow_origin_regex` - A regex string to match against origins that should be permitted to make cross-origin requests. e.g. `'https://.*\.example\.org'`.

!!! note "Технические детали"
    Любая функция, с которой может работать:

    * <a href="https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager" class="external-link" target="_blank">`@contextlib.contextmanager`</a> или
    * <a href="https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager" class="external-link" target="_blank">`@contextlib.asynccontextmanager`</a>

!!! tip "提示"
    确保只使用一次 `yield` 。

!!! note "技术细节"

    任何一个可以与以下内容一起使用的函数：

    * <a href="https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager" class="external-link" target="_blank">`@contextlib.contextmanager`</a> 或者
    * <a href="https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager" class="external-link" target="_blank">`@contextlib.asynccontextmanager`</a>

    * Il existe cependant une solution à ce problème.
* Il existe une extension du protocole TLS (celui qui gère le cryptage au niveau TCP, avant HTTP) appelée <a

  title="Server Name Indication (indication du nom du serveur)">SNI (indication du nom du serveur)</abbr></a>.

Por exemplo, ele não recebe objetos `datetime`, pois estes objetos não são compatíveis com JSON.

Então, um objeto `datetime` teria que ser convertido em um `str` contendo os dados no formato  <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO</a>.

Da mesma forma, este banco de dados não receberia um modelo Pydantic (um objeto com atributos), apenas um `dict`.

它基于 <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>， 而HTTPX又是基于Requests设计的，所以很相似且易懂。

有了它，你可以直接与**FastAPI**一起使用 <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a>。

## 使用 `TestClient`

!!! info "信息"
    要使用 `TestClient`，先要安装 <a href="https://www.python-httpx.org" class="external-link" target="_blank">`httpx`</a>.

    例：`pip install httpx`.
