2. In Postman, the request parameters are shown in Figure 1.
Plaintext

0[config_task_id]:2
0[exec_user_id]:8
0[place]:Location 7 under the title of Morning News 1

3. At the frontend’s request, a form name was added. \api\rests\plan_task\CreateAction.php. The code is as follows:

/**
* 指派(创建任务)
*
* 1、请求参数列表
* (1)plan_id 必填，选题ID
* (2)title 必填，任务标题
* (3)config_task_id 必填，任务配置(类型)ID
* (4)exec_user_id 必填，执行用户ID
* (5)place 必填，地点
* (6)task_info 必填，任务信息
*
* 2、输入数据验证规则
* (1)必填：plan_id, title, config_task_id, exec_user_id, place, task_info；
* (2)存在性：config_task_id 必须存在于任务配置模型中，且其状态为 1：启用；
* (3)存在性：plan_id 必须存在于选题模型中，且其状态为 3：通过/5：指派；
* (4)存在性：plan_id 选题所属栏目ID必须存在，且其状态为 1：启用；
* (5)存在性：create_user_id 必须存在于选题所属栏目的人员配置模型中，且其状态为 1：启用；
* (6)存在性：exec_user_id 必须存在于选题所属栏目的人员配置模型中，且其状态为 1：启用；
* (7)默认值('')：'place', 'task_info'；
*
* 3、操作数据(事务)
* (1)循环插入任务(传递 false 作为 [[save()]]的一个参数使其不会重复验证两次)；
* (2)批量插入任务步骤，创建批量 INSERT 命令(batchInsert)；
* (3)更新选题状态：指派；
*
