asp.net core系统自带的异常页面色彩给人感觉模糊、朦胧,晕眩!
原版:
美化版
实现思路:(在系统自带异常中间件“DeveloperExceptionPageMiddleware”执行后,调用自定义的异常中间件“DeveloperExceptionPrettifyMiddleware”,继续向响应流输出美化的css和js)
/// <summary>/// 开发环境异常页面css美化 中间件/// </summary>public class DeveloperExceptionPrettifyMiddleware{private readonly RequestDelegate _next;public DeveloperExceptionPrettifyMiddleware(RequestDelegate next){_next = next;}public async Task Invoke(HttpContext context){await _next.Invoke(context);if (context.Response.StatusCode == 500) // 通过 StatusCode 判断程序报错{using (TextWriter output = (TextWriter)new StreamWriter(context.Response.Body,new UTF8Encoding(false, true), 4096, true)){// 美化版 css/jsvar chars = @\"<style>body{ color: inherit}h1{color:red}h3{color:inherit}.titleerror{color:maroon}body .location{ }#header li{color:blue}#header .selected{background:#44525e}#stackpage .source ol li{background-color:#ffffcc}#stackpage .source ol.collapsible li span{color:#000}.rawExceptionStackTrace{background-color:#ffffcc; padding:.5rem}:focus{outline:none}.showRawException{color:blue}</style><script>document.querySelector(\'.expandCollapseButton\').click()</script>\".ToCharArray();// 输出到响应流中await output.WriteAsync(chars, 0, chars.Length);await output.FlushAsync();}}}}
使用中间件(注意顺序)
