ASP.NetCore中设置JSON中DateTime类型的格式化（解决时间返回T格式）

  public IActionResult Get()
        {
            UserInfo userInfo = new UserInfo()
            {
                Name = "lxsh",
                BirthDay = DateTime.Now 
            };
        
            return Ok(userInfo);
        }

 services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2).AddJsonOptions(optiOns=>
            {
                options.SerializerSettings.DateFormatString = "yyyy-MM-dd HH:mm:ss";
            });
