.Net Core 前台添加赋值POST提交到Api控制实现添加

使用Form表单提交到数据库

这两个必须要写，不能写这样的格式，会提交获取不到数据

contentType: 'application/json',
正确格式：

 contentType: 'application/x-www-form-urlencoded',
 accepts:'application/x-www-form-urlencoded',

Api代码

 [EnableCors("any")]
        [Route("insert")]
        [HttpPost]
        public int Add([FromForm] ProductInfoModel model)
        {
            try
            { 
                int h = _pbll.Add(model);

                if (h > 0)
                {
                    return 1;//添加成功;
                }
                else
                {
                    return 0;//登录失败;
                }

            }
            catch (Exception)
            {
                throw;
            }

        }
