DotNetCore 1.0 MVC 如何在直播中自动重定向到单个域

DotNetCore 1.0 MVC how to automatically redirect to a single domain in live

我有一个网站的多个域:

http://example.com

http://www.example.com

http://www.example.co.uk

在生产中,我希望主域为 http://www.example.com,所有其他关联域自动重定向到主域。

过去,我会使用 URLRewrite 完成此操作,但是我被引导相信 DotNetCore 中不存在。

那么...我该怎么做?

此外,我不希望这影响开发环境。

您可以在 .NET Core 中使用 URLRewrite - 只需下载 ASP.NET Core 1.1 Preview 1。然后您就可以:

public class Startup {

    public void Configure(IApplicationBuilder app, IHostingEnvironment env) {

        var options = new RewriteOptions()
            .AddRedirect("(.*)/$", "")                    // Redirect using a regular expression
            .AddRewrite(@"app/(\d+)", "app?id=", skipRemainingRules: false) // Rewrite based on a Regular expression
            .AddRedirectToHttps(302, 5001)                  // Redirect to a different port and use HTTPS
            .AddIISUrlRewrite(env.ContentRootFileProvider, "UrlRewrite.xml")        // Use IIS UrlRewriter rules to configure
            .AddApacheModRewrite(env.ContentRootFileProvider, "Rewrite.txt");       // Use Apache mod_rewrite rules to configure

        app.UseRewriter(options);
    }   
}

要将现有项目更新到 ASP.NET Core 1.1 Preview 1,您需要执行以下操作:

  • 下载并安装更新的 .NET Core 1.1 Prevew 1 SDK
  • 按照 .NET Core 1.1 预览版 1 公告中的说明更新您的项目以使用 .NET Core 1.1 预览版 1
  • 更新您的 ASP.NET 核心包依赖项以使用新的 1.1.0-preview1 版本

适用于 DotNetCore 1.0 的答案(也强制 https)

Startup.cs

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    // Other configuration code here...

    if (env.IsProduction())
    {
        app.Use(async (context, next) =>
        {
            if (context.Request.Host != new HostString("www.example.com"))
            {
                var withDomain = "https://www.example.com" + context.Request.Path;
                context.Response.Redirect(withDomain);
            }
            else if (!context.Request.IsHttps)
            {
                var withHttps = "https://" + context.Request.Host + context.Request.Path;
                context.Response.Redirect(withHttps);
            }
            else
            {
                await next();
            }
        });
    }
}

在 .net 核心 6 中:

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();

    var options = new RewriteOptions()
    .Add(RewriteRules.ReDirectRequestsToOneHost);

    app.UseRewriter(options);
}


public class RewriteRules
{
    public static void ReDirectRequestsToOneHost(RewriteContext context)
    {
        var request = context.HttpContext.Request;

        if (request.Host != new HostString("www.example.com"))
        {
            var redirect = $"{request.Scheme}://www.example.com{request.Path}";
        
            context.HttpContext.Response.Redirect(redirect);
        }
    }
}
