前言
作為一個.NET Web開發者,我最傷心的時候就是專案開發部署時面對Windows Server上貧瘠的解決方案,同樣是神器Nginx,Win上的Nginx便始終不如Linux上的,你或許會說“幹嘛不用windows自帶的NLB呢”,那這就是我這個小鳥的從眾心理了,君不見Stack Overflow 2016最新架構中,用的負載和緩存技術也都是採用在Linux上已經成熟的解決方案嗎。沒辦法的時候找個適合的解決方法是好事,有辦法的時候當然要選擇最好的解決方法。
所幸,.ASP.NET Core出現了,它順應了開源大趨勢,擺脫了一直為人詬病的Win Server,以ASP.NET的跨平台版本出現在了我們的眼前。暫且不論Benchmark中無聊的效能比較,也不探討將來是否能和JAVA,PHP Web應用分庭抗禮,但是至少對我們.NET平台開發者來說,我們多了一種開發方向,也多了一個嘗試前沿成熟技術的機會。下面話不多說了,本文主要介紹的是asp.net core在輸出中文時亂碼的問題,下面來一起看看吧。
問題重現
新建控制台和站點
public class Program { public static void Main(string[] args) { Console.WriteLine("您好,北京欢迎你"); Console.Read(); } }
站點
public class Startup { // This method gets called by the runtime. Use this method to add services to the container. // For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=398940 public void ConfigureServices(IServiceCollection services) { } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { loggerFactory.AddConsole(); if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } app.Run(async (context) => { await context.Response.WriteAsync("您好,北京欢迎你"); }); } }
那麼我們取得「GB2312」編碼,然後對其編碼呢?
public static void Main(string[] args) { Console.WriteLine("您好,北京欢迎你"); try { Console.WriteLine(Encoding.GetEncoding("GB2312")); } catch (Exception ex) { Console.WriteLine(ex.Message); } Console.Read(); } }
'GB2312' is not a supported encoding name. For information on defining a custom encoding, see the documentation for information on defining a custom encoding, see the documentation for information on defining a custom encoding, see the documentation for thenidodion 的意思是上面。 coding 不支援GB2312編碼,需要使用Encoding.RegisterProvider方法進行註冊Provider。
try { Encoding.RegisterProvider(CodePagesEncodingProvider.Instance); Console.WriteLine(Encoding.GetEncoding("GB2312")); } catch (Exception ex) { Console.WriteLine(ex.Message); } Console.Read();
