        /// </summary>
        /// <param name="ps"></param>

        public string PostPeoples([FromBody]List<People> ps)

            foreach (var item in ps)
            {

Postman 调用(错误版本)

 

Postman 调用(正确版本)

1.注意如果list不是内嵌对象则不需要名称，如果上面的错误示范ps

2.如果是内嵌对象这是需要的。

{"id":671202,"trainName":"test", "trainContent":"content","accessUser":[{"account":"123","name":"zhangsan"},{"account":"345","name":"lisi"}]}  

如下：accessUser

public class SafeTrainReq {
    private String trainName;
    private String trainContent;
    private List<SafeTrainUser> accessUser;
