.NET Core 过滤器实现
public class GlobalExceptionFilter:Attribute, IExceptionFilter
{
private readonly IHostingEnvironment _hostingEnvironment;
private readonly IModelMetadataProvider _modelMetadataProvider;
public GlobalExceptionFilter(
IHostingEnvironment hostingEnvironment,
IModelMetadataProvider modelMetadataProvider)
{
_hostingEnvironment = hostingEnvironment;
_modelMetadataProvider = modelMetadataProvider;
}
/// <summary>
/// 发生异常进入
/// </summary>
/// <param name="context"></param>
public async void OnException(ExceptionContext context)
{
ContentResult result = new ContentResult
{
StatusCode = 500,
ContentType = "text/json;charset=utf-8;"
};
if (_hostingEnvironment.IsDevelopment())
{
var json = new { message = context.Exception.Message };
result.Content = JsonConvert.SerializeObject(json);
}
else
{
result.Content = "抱歉，出错了";
}
context.Result = result;
context.ExceptionHandled = true;
}
}
