标准表单提交示例代码

以用户注册为示例

第一步：添加视图模型

 public class ViewRegModels
 {
     [Display(Name = "用户名")]
     [Required(AllowEmptyStrings = false, ErrorMessage = "用户名不能为空")]
     public string UserName { get; set; }

     [Display(Name = "密码"), DataType(DataType.Password)]
     [Required(AllowEmptyStrings = false, ErrorMessage = "密码不能为空")]
     public string Password { get; set; }

     [Display(Name = "确认密码"), DataType(DataType.Password)]
     [Required(AllowEmptyStrings = false, ErrorMessage = "确认密码不能为空")]
     [Compare("Password", ErrorMessage = "密码与确认密码不相同")]
     public string ConfrimPassword { get; set; }


     public string ReturnUrl { get; set; }
 }

第二步：添加控制器

1. 添加HttpGet
   

   [HttpGet]
    public IActionResult Reg() {
        return View();
    }
   

2. 添加HttpPost
   

   [HttpPost]
   public async Task<IActionResult> Reg(ViewRegModels view) {
       if (!this.IsFormValid()) {
           ModelState.AddModelError(string.Empty, this.FormInvalidReason());
           return await Task.FromResult(View(view));
       }
       var result = Resolve<IUserService>().Reg(view.UserName, view.Password);
       if (!result.Succeeded) {
           ModelState.AddModelError(string.Empty, result.ToString());
           return await Task.FromResult(View(view));
       }
       string url = Resolve<IAutoConfigService>().GetData<UserLoginRegConfig>().AfterRegUrl;
       if (url.IsNullOrEmpty()) {
           url = "/Index";
       }
       return Redirect(url);
   }
   

3. 注意事项
   
   • 必须使用 this.IsFormValid 来验证所有的字段
   • 使用this.FormInvalidReason显示某个字段的具体错误验证信息
   • ModelState.AddModelError 将表单提交的错误信息显示处理
   • 尽可能的使用异步提交

第三步：添加视图View文件

@model ZKCloud.Core.User.ViewModels.ViewRegModels

<div class="UserLogin row">
    <form method="post" class="form-horizontal form-row-seperated"  asp-controller="User" asp-action="Reg" >

        <div class="form-group-error">
            <div class="col-md-offset-2 col-md-10">
                <div asp-validation-summary="All" class="text-danger"></div>
            </div>
        </div>
       
        <div class="form-group">
            <label asp-for="UserName" class="col-md-2 control-label"></label>
            <div class="col-md-10">
                <input asp-for="UserName" class="form-control" />
                <span asp-validation-for="UserName" class="text-danger"></span>
            </div>
        </div>

        <div class="form-group">
            <label asp-for="Password" class="col-md-2 control-label"></label>
            <div class="col-md-10">
                <input asp-for="Password" class="form-control" />
                <span asp-validation-for="Password" class="text-danger"></span>
            </div>
        </div>

        <div class="form-group">
            <label asp-for="ConfrimPassword" class="col-md-2 control-label"></label>
            <div class="col-md-10">
                <input asp-for="ConfrimPassword" class="form-control" />
                <span asp-validation-for="ConfrimPassword" class="text-danger"></span>
            </div>
        </div>


        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <button class="btn green btn-big">会员注册</button>
            </div>
        </div>

    </form>
</div>

 注意事项：

• • 使用<div asp-validation-summary="All" class="text-danger"></div>来显示所有的错误验证信息
  • 所以得字段必须添加验证<span asp-validation-for="ConfrimPassword" class="text-danger"></span>
  • 为了减低不必要的工作量，以及沟通成本。不允许纯原声的HTML样式
  • 所有的后台人员必须完全掌握该HTML结构
  •
