如何使用.NET核心3.1中的全局异常自定义筛选器显示错误模式？
如何使用.NET核心3.1中的全局异常自定义筛选器显示错误模式？
提问于 2020-04-23 16:50:08
我实现了以下全局自定义异常筛选器：
public class ExceptionCustomFilter : IExceptionFilter
{
private readonly IWebHostEnvironment _hostingEnvironment;
private readonly IModelMetadataProvider _modelMetadataProvider;
private readonly IHttpContextAccessor _httpContextAccessor;
public ExceptionCustomFilter(
IWebHostEnvironment hostingEnvironment,
IModelMetadataProvider modelMetadataProvider,
IHttpContextAccessor httpContextAccessor)
{
_hostingEnvironment = hostingEnvironment;
_modelMetadataProvider = modelMetadataProvider;
_httpContextAccessor = httpContextAccessor;
}
public void OnException(ExceptionContext filterContext)
{
//Redirect to global handler
filterContext.Result = new ViewResult();
{
ViewName = "Error"
};
filterContext.ExceptionHandled = true;
filterContext.HttpContext.Response.Clear();
}
}我在Startup ConfigureServices()方法中添加了以下代码：
services.AddControllersWithViews(options =>
{
options.Filters.Add(typeof(ExceptionCustomFilter));
});
services.AddMvc(options =>
{
options.EnableEndpointRouting = false;
options.Filters.Add(typeof(ExceptionCustomFilter));
}); 我想让我的"Error“视图(它目前在我的视图>共享文件夹中找到)在每次ExceptionFilter捕获任何异常时作为一个模式弹出。
我现在的"Error.cshtml“视图：
// Render styles
<script type="text/javascript">
$(function () {
$('#modalError').modal('show');
});
</script>
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<div class="error">
<i class="icon-erro fa fa-exclamation-circle" aria-hidden="true"></i>
<h2> Error </h2>
</div>
</div>
<div class="modal-body">
<div class="error">
<p>
// content
</p>
</div>
</div>
</div>

更新:我设法弄清楚了，显然有些div ids丢失了，我返回的是一个ViewResult而不是一个PartialViewResult.
以下是完整的代码：
在我的自定义异常过滤器中
public void OnException(ExceptionContext filterContext)
{
var logErroService = new LogErroService(filterContext.HttpContext);
logErroService.Create(filterContext.Exception);
if (IsAjaxRequest(filterContext.HttpContext.Request))
{
// Displays the error message as a modal
filterContext.Result = new PartialViewResult()
{
ViewName = "_ModalError"
};
filterContext.ExceptionHandled = true;
filterContext.HttpContext.Response.Clear();
}
else
{
// Displays the error message as a HTML Page
filterContext.Result = new ViewResult()
{
ViewName = "_Error"
};
filterContext.ExceptionHandled = true;
filterContext.HttpContext.Response.Clear();
}
}我的_Error.cshtml视图：
@{
Layout = null;
}
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<!--Local-->
// Import styles and scripts
<title>Ops, an error has ocurred!</title>
</head>
<body>
<div class="error">
<i class="icon-erro fa fa-exclamation-circle" aria-hidden="true"></i>
<h2>Error</h2>
</div>
</body>
</html>当错误来自AJAX请求时称为ONLY的：
<!-- Local -->
// Import styles and scripts
<script type="text/javascript">
$(function () {
$('#ModalError').modal();
});
</script>
<div class='modal fade' id='ModalError'>
<div id='divModalErrorBody'>
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-body">
<button type="button" class="close" data-dismiss="modal">
<span aria-hidden="true">×</span>
<span class="sr-only">Exit</span>
</button>
<div class="error-modal">
<i class="icon-erro fa fa-exclamation-circle" aria-hidden="true"></i>
<h2> Error </h2>
</div>
</div>
</div>
</div>
</div>
