如何使用 Java 代码在 Jmeter .jmx 文件中添加正则表达式提取器和 cookie 管理器？

Question

我正在使用 Java 代码为 Jmeter GUI 编写 .jmx 文件。我想从用于 "login" 的 HTTP 代理采样器中提取 GET 响应，该响应用作识别用户的会话 ID。此外，我需要下一个采样器来使用正在提取的变量。另外，我还需要每个线程组一个cookie管理器。

我应该调用哪个 API 将提取器添加到 http 代理采样器并将 cookie 管理器添加到线程组？

我已经创建了http采样器，设置了路径和参数。我现在只需要一个提取器来帮助我获取变量和一个 cookie 管理器

下面是我创建线程组并将http采样器添加到线程组的代码
