iis – URL重定向失败

情况草图：

我已经在asp.net核心创建了一个网站,我已经开始运行了.
几天前,我的托管服务提供商添加了配置SSL的选项,所以我这样做让我遇到了没有从http重定向到https的问题.
我已经开始在网上寻找解决方案,并找出了一些代码,这些代码在主机上的4个案例中的3个中有效,在IIS上本地测试的4个案例中有4个.

什么有效：

> https://www.someurl.com – >不需要重定向
> https://someurl.com – >重定向到https://www.someurl.com
> http://someurl.com – >重定向到https://www.someurl.com
> http://www.someurl.com – >给出重定向错误：ERR_TOO_MANY_REDIRECTS

以下代码用于asp.net核心站点：

public void Configure(...) {
  app.UseHttpsWorldWideWebRedirect();
}

public static class HttpsWorldWideWebRedirectMiddlewareExtensions
    {
        public static IApplicationBuilder UseHttpsWorldWideWebRedirect(this IApplicationBuilder builder)
        {
            return builder.UseMiddleware<HttpsWorldWideWebRedirectMiddleware>();
        }
    }

public class HttpsWorldWideWebRedirectMiddleware
{
    private readonly RequestDelegate _next;
    private readonly ILogger<HttpsWorldWideWebRedirectMiddleware> _logger;

    public HttpsWorldWideWebRedirectMiddleware(RequestDelegate next, ILogger<HttpsWorldWideWebRedirectMiddleware> logger)
    {
        _next = next;
        _logger = logger;
        _logger.LogInformation("Https WWW redirect module loaded");
    }

    public async Task Invoke(HttpContext context)
    {
        var protoHeader = context.Request.Headers["X-Forwarded-Proto"].ToString();
        var ignoreHttps = false;
        var ignoreWww = false;

        if (context.Request.IsHttps || protoHeader.ToLower().Equals("https"))

        {
            ignoreHttps = true;
        }

        if (context.Request.Host.Host.StartsWith("www", StringComparison.OrdinalIgnoreCase) || string.Equals(context.Request.Host.Host, "localhost", StringComparison.OrdinalIgnoreCase))
        {
            ignoreWww = true;
        }

        if (ignoreWww && ignoreHttps)
        {
            await _next.Invoke(context);
        }
        else
        {
            var www = ignoreWww ? "" : "www.";
            var newPath =
                $"https://{www}{context.Request.Host.Value}{context.Request.PathBase}{context.Request.Path}{context.Request.QueryString}";
            _logger.LogDebug($"'{context.Request.GetDisplayUrl()}' was rewritten into '{newPath}'");
            context.Response.Headers["X-Forwarded-Proto"] = "https";
            context.Response.Redirect(newPath, true);
        }
    }
}

我尝试的下一步是在web.config中添加一个重定向,以涵盖使用以下代码无法运行asp.net重定向的情况：

<rewrite>
  <rules>
    <rule name="Redirect to https if http://www" stopProcessing="true">
      <match url="(.*)" />
      <conditions logicalGrouping="MatchAny">
        <add input="{HTTP_HOST}" pattern="^www.*"/>
        <add input="{HTTPS}" pattern="Off" />
      </conditions>
      <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Permanent" />
    </rule>
  </rules>
</rewrite>

作为测试我添加了“iwork”这一行：
 

结果仍然是错误的重定向太多,但随后将http://someurl.com/iworkiworkiworkiworkiworkiworkiworkiworkiworkiwork作为生成的url.

所以我对于究竟出了什么问题以及如何解决它的想法,任何想法都感到茫然？

对.NET Core一无所知,但这肯定可以通过URL重写规则来完成.

您至少需要2个重写规则.

>使用www将http请求重定向到https.
>重定向https请求,没有www.使用www前缀到https.

这将尽可能减少重定向链.

<rewrite>
    <rules>
        <rule name="Redirect all http requests to https with www" stopProcessing="true">
            <match url=".*" />
            <conditions trackAllCaptures="true">
                <add input="{HTTP_HOST}" pattern="^localhost" negate="true" />
                <add input="{HTTPS}" pattern="off" />
                <add input="{HTTP_HOST}" pattern="^(?:www\.)?(.+)$" />
            </conditions>
            <action type="Redirect" url="https://www.{C:1}/{R:0}" />
        </rule>
        <rule name="Redirect https requests with no www prefix to https with www" stopProcessing="true">
            <match url=".*" />
            <conditions>
                <add input="{HTTP_HOST}" pattern="^localhost" negate="true" />
                <add input="{HTTPS}" pattern="on" />
                <add input="{HTTP_HOST}" pattern="^www\." negate="true" />
            </conditions>
            <action type="Redirect" url="https://www.{HTTP_HOST}/{R:0}" />
        </rule>
    </rules>
</rewrite>
