你需要URL重写模块，最好是v2(我没有安装v1，所以不能保证它会在那里工作，但它应该)。

这是一个这样的网络的例子。config——它将强制所有资源使用HTTPS(使用301永久重定向):

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <clear />
                <rule name="Redirect to https" stopProcessing="true">
                    <match url=".*" />
                    <conditions>
                        <add input="{HTTPS}" pattern="off" ignoreCase="true" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

注: 这个特殊的解决方案与ASP没有任何关系。NET/PHP或任何其他技术，因为它只使用URL重写模块完成——在请求到达代码执行点之前，它在初始/较低的级别之一进行处理。

一个简单的方法是告诉IIS为HTTP请求发送自定义错误文件。该文件可以包含一个元重定向，一个JavaScript重定向和指令链接，等等…重要的是，您仍然可以为站点(或文件夹)选择“要求SSL”，这将会工作。

</configuration>
</system.webServer>
    <httpErrors>
        <clear/>
        <!--redirect if connected without SSL-->
        <error statusCode="403" subStatusCode="4" path="errors\403.4_requiressl.html" responseMode="File"/>
    </httpErrors>
</system.webServer>
</configuration>

对于那些使用ASP。净MVC。您可以使用requirehttpattribute强制所有响应为HTTPS:

GlobalFilters.Filters.Add(new RequireHttpsAttribute());

你可能还想做其他事情来帮助保护你的网站:

Force Anti-Forgery tokens to use SSL/TLS: AntiForgeryConfig.RequireSsl = true; Require Cookies to require HTTPS by default by changing the Web.config file: <system.web> <httpCookies httpOnlyCookies="true" requireSSL="true" /> </system.web> Use the NWebSec.Owin NuGet package and add the following line of code to enable Strict Transport Security (HSTS) across the site. Don't forget to add the Preload directive below and submit your site to the HSTS Preload site. More information here and here. Note that if you are not using OWIN, there is a Web.config method you can read up on on the NWebSec site. // app is your OWIN IAppBuilder app in Startup.cs app.UseHsts(options => options.MaxAge(days: 720).Preload()); Use the NWebSec.Owin NuGet package and add the following line of code to enable Public Key Pinning (HPKP) across the site. More information here and here. // app is your OWIN IAppBuilder app in Startup.cs app.UseHpkp(options => options .Sha256Pins( "Base64 encoded SHA-256 hash of your first certificate e.g. cUPcTAZWKaASuYWhhneDttWpY3oBAkE3h2+soZS7sWs=", "Base64 encoded SHA-256 hash of your second backup certificate e.g. M8HztCzM3elUxkcjR2S5P4hhyBNf6lHkmjAHKhpGPWE=") .MaxAge(days: 30)); Include the https scheme in any URL's used. Content Security Policy (CSP) HTTP header and Subresource Integrity (SRI) do not play nice when you imit the scheme in some browsers. It is better to be explicit about HTTPS. e.g. <script src="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.4/bootstrap.min.js"> </script> Use the ASP.NET MVC Boilerplate Visual Studio project template to generate a project with all of this and much more built in. You can also view the code on GitHub.

出色的NWebsec库可以使用Web.config中的upgrade-insecure-requests标签将您的请求从HTTP升级到HTTPS:

<nwebsec>
  <httpHeaderSecurityModule>
    <securityHttpHeaders>
      <content-Security-Policy enabled="true">
        <upgrade-insecure-requests enabled="true"  />
      </content-Security-Policy>
    </securityHttpHeaders>
  </httpHeaderSecurityModule>
</nwebsec>

为了补充LazyOne的答案，这里有一个注释版本的答案。

<rewrite>
  <rules>
     <clear />
     <rule name="Redirect all requests to https" stopProcessing="true">
       <match url="(.*)" />
         <conditions logicalGrouping="MatchAll">
           <add input="{HTTPS}" pattern="off" ignoreCase="true" />
         </conditions>
         <action 
            type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" 
            redirectType="Permanent" appendQueryString="false" />
     </rule>
  </rules>
</rewrite>

Clear all the other rules that might already been defined on this server. Create a new rule, that we will name "Redirect all requests to https". After processing this rule, do not process any more rules! Match all incoming URLs. Then check whether all of these other conditions are true: HTTPS is turned OFF. Well, that's only one condition (but make sure it's true). If it is, send a 301 Permanent redirect back to the client at http://www.foobar.com/whatever?else=the#url-contains. Don't add the query string at the end of that, because it would duplicate the query string!

这就是属性、属性和一些值的含义。

clear removes all server rules that we might otherwise inherit. rule defines a rule. name an arbitrary (though unique) name for the rule. stopProcessing whether to forward the request immediately to the IIS request pipeline or first to process additional rules. match when to run this rule. url a pattern against which to evaluate the URL conditions additional conditions about when to run this rule; conditions are processed only if there is first a match. logicalGrouping whether all the conditions must be true (MatchAll) or any of the conditions must be true (MatchAny); similar to AND vs OR. add adds a condition that must be met. input the input that a condition is evaluating; input can be server variables. pattern the standard against which to evaluate the input. ignoreCase whether capitalization matters or not. action what to do if the match and its conditions are all true. type can generally be redirect (client-side) or rewrite (server-side). url what to produce as a result of this rule; in this case, concatenate https:// with two server variables. redirectType what HTTP redirect to use; this one is a 301 Permanent. appendQueryString whether to add the query string at the end of the resultant url or not; in this case, we are setting it to false, because the {REQUEST_URI} already includes it.

服务器变量为

{HTTPS}是关闭或打开。 {HTTP_HOST}是www.mysite.com，和 {REQUEST_URI}包含URI的其余部分，例如/home?键=值 浏览器处理#片段(参见LazyOne的评论)。

公认的答案对我不起作用。 我遵循了这个博客上的步骤。

我缺少的一个关键点是，我需要下载并安装IIS的URL重写工具。我在这里找到的。结果如下。

<rewrite>
        <rules>
            <remove name="Http to Https" />
            <rule name="Http to Https" enabled="true" patternSyntax="Wildcard" stopProcessing="true">
                <match url="*" />
                <conditions>
                    <add input="{HTTPS}" pattern="off" />
                </conditions>
                <serverVariables />
                <action type="Redirect" url="https://{HTTPS_HOST}{REQUEST_URI}" />
            </rule>
        </rules>
    </rewrite>

我不允许在我的环境中安装URL重写，所以，我找到了另一个路径。

把这个加到我的网里。config添加了错误重写，并适用于iis7.5:

<system.webServer>
    <httpErrors errorMode="Custom" defaultResponseMode="File" defaultPath="C:\WebSites\yoursite\" >    
    <remove statusCode="403" subStatusCode="4" />
    <error statusCode="403" subStatusCode="4" responseMode="File" path="redirectToHttps.html" />
</httpErrors>

然后，按照这里的建议:https://www.sslshopper.com/iis7-redirect-http-to-https.html

我将IIS网站配置为需要SSL，并创建了html文件，在403(禁止)错误时执行重定向(redirectToHttps.html):

<html>
<head><title>Redirecting...</title></head>
<script language="JavaScript">
function redirectHttpToHttps()
{
    var httpURL= window.location.hostname + window.location.pathname + window.location.search;
    var httpsURL= "https://" + httpURL;
    window.location = httpsURL;
}
redirectHttpToHttps();
</script>
<body>
</body>
</html>

我希望有人发现这是有用的，因为我无法找到所有的碎片在一个地方在其他地方。

在.Net Core中，请遵循https://learn.microsoft.com/en-us/aspnet/core/security/enforcing-ssl上的说明

在startup.cs中添加以下内容:

// Requires using Microsoft.AspNetCore.Mvc;
public void ConfigureServices(IServiceCollection services)
{
    services.Configure<MvcOptions>(options =>
    {
        options.Filters.Add(new RequireHttpsAttribute());
    });`enter code here`

要将Http重定向到Https，请在startup.cs . xml文件中添加以下内容

// Requires using Microsoft.AspNetCore.Rewrite;
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    var options = new RewriteOptions()
       .AddRedirectToHttps();

    app.UseRewriter(options);

我正在使用下面的代码，它完美地为我工作，希望它会帮助你。

<configuration>
<system.webServer>
    <rewrite>
        <rules>
            <rule name="Force redirect to https" stopProcessing="true">
                <match url="(.*)" />
                <conditions>
                    <add input="{HTTPS}" pattern="^OFF$" />
                </conditions>
                <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" appendQueryString="false" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

当您在AWS上使用带有应用程序负载均衡器的IIS 10时，必须按以下方式配置重定向。

        <rule name="Force HTTPS" enabled="true" stopProcessing="true">
            <match url="(.*)" />
            <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                <add input="{HTTP_X_Forwarded_Proto}" pattern="^https$" negate="true" />
                <add input="{HTTP_HOST}" pattern="^(www\.)?dname\.com$" />
            </conditions>
            <action type="Redirect" url="https://www.dname.com{REQUEST_URI}" />
        </rule>

如果你有子域重定向使用如下:

        <!--START REDIRECT TO HTTPS-->
        <rule name="Force HTTPS" enabled="true" stopProcessing="true">
            <match url="(.*)" />
            <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                <add input="{HTTP_X_Forwarded_Proto}" pattern="^https$" negate="true" />
                <add input="{HTTP_HOST}" pattern="subdomain\.domain\.com$" />
            </conditions>
            <action type="Redirect" url="https://subdomain.domain.com{REQUEST_URI}" />
        </rule> 
        <!--END REDIRECT TO HTTPS-->
