接着只需在测试中同样操作。

示例：

* 传一个*路径* 或*查询* 参数，添加到URL上。
* 传一个JSON体，传一个Python对象(例如一个`dict`)到参数 `json`。
* 如果你需要发送 *Form Data* 而不是 JSON，使用 `data` 参数。
* 要发送 *headers*，传 `dict` 给 `headers` 参数。
* 对于 *cookies*，传 `dict` 给 `cookies` 参数。

关于如何传数据给后端的更多信息 (使用`httpx` 或 `TestClient`)，请查阅 <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX 文档</a>.
