需要使用java在免费标记模板中添加多个字段

Question

我正在研究放心的 API 测试框架。我有不同的 API 调用来发布/放置。 使用自由标记模板创建我的 post/put 调用。我需要为每个请求输入不同的值来测试不同的场景。我可以成功地在模板中传递一个值，但是当需要更多时不能这样做。需要一些循环，但不知道如何。 下面是我的功能文件和放心类的代码。

Scenario Outline: to post data
  # Given user hit post button
    When user sends the as follow
      | key        | values   |
      | guid       | abcd |
      | first_name | testname |
|last_name| lastname|
    Then user gets success results for "<name>"
    Examples:
      | name  |
      | test7 |

Step definition for line 2

 @When("user sends the as follow")
    public void userSendsTheAsFollow(DataTable table) throws IOException {
      List<Map<String, String>> rows = table.asMaps(String.class, String.class);
       for (Map<String, String> columns : rows){
            post(columns.get("key"), columns.get("values"),table);
  
            
       }
    }

///postTemplate.ftl

{
    "guid": "${guid}",
        "contact_details": {
        "first_name": "${first_name}",
        "last_name": "${last_name}",
        "email": "abcd@test.com",
        "phone": "02112231223"
    }
}

请帮我把 guid、first_name 和 last_name 放在文件中。

提前致谢
