大约6个月前,我推出了一个网站,每个请求都需要通过https。当时我能找到的确保每个页面请求都是通过https的唯一方法是在页面加载事件中检查它。如果请求不是通过http,我会response.redirect("https://example.com")
有没有更好的方法,比如web。config中的一些设置?

这也取决于你的平衡器的品牌,对于web mux,你需要寻找http头x- webmux - ssl - terminate: true来计算传入的流量是ssl。详情:http://www.cainetworks.com/support/redirect2ssl.html

请使用HSTS (HTTP严格传输安全)
从http://www.hanselman.com/blog/HowToEnableHTTPStrictTransportSecurityHSTSInIIS7.aspx
<?xml version="1.0" encoding="UTF-8"?>

原答案(2015年12月4日取代)
基本上
protected void Application_BeginRequest(Object sender, EventArgs e)
{
if (HttpContext.Current.Request.IsSecureConnection.Equals(false) && HttpContext.Current.Request.IsLocal.Equals(false))
{
Response.Redirect("https://" + Request.ServerVariables["HTTP_HOST"]
+ HttpContext.Current.Request.RawUrl);
}
}
它会被放到global。asax。cs(或global。asax。vb)
我不知道如何在web.config中指定它
如果你不能在IIS中设置这个,我会做一个HTTP模块,为你重定向:
using System;
using System.Web;
namespace HttpsOnly
{
/// <summary>
/// Redirects the Request to HTTPS if it comes in on an insecure channel.
/// </summary>
public class HttpsOnlyModule : IHttpModule
{
public void Init(HttpApplication app)
{
// Note we cannot trust IsSecureConnection when
// in a webfarm, because usually only the load balancer
// will come in on a secure port the request will be then
// internally redirected to local machine on a specified port.
// Move this to a config file, if your behind a farm,
// set this to the local port used internally.
int specialPort = 443;
if (!app.Context.Request.IsSecureConnection
|| app.Context.Request.Url.Port != specialPort)
{
app.Context.Response.Redirect("https://"
+ app.Context.Request.ServerVariables["HTTP_HOST"]
+ app.Context.Request.RawUrl);
}
}
public void Dispose()
{
// Needed for IHttpModule
}
}
}
然后将其编译为DLL,将其作为项目的引用添加到web.config中:
<httpModules>
<add name="HttpsOnlyModule" type="HttpsOnly.HttpsOnlyModule, HttpsOnly" />
</httpModules>
这是基于@特洛伊·亨特的更全面的回答。将这个函数添加到Global.asax.cs中的WebApplication类中:
protected void Application_BeginRequest(Object sender, EventArgs e)
{
// Allow https pages in debugging
if (Request.IsLocal)
{
if (Request.Url.Scheme == "http")
{
int localSslPort = 44362; // Your local IIS port for HTTPS
var path = "https://" + Request.Url.Host + ":" + localSslPort + Request.Url.PathAndQuery;
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location", path);
}
}
else
{
switch (Request.Url.Scheme)
{
case "https":
Response.AddHeader("Strict-Transport-Security", "max-age=31536000");
break;
case "http":
var path = "https://" + Request.Url.Host + Request.Url.PathAndQuery;
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location", path);
break;
}
}
}
(要在本地构建中启用SSL,请在项目的Properties dock中启用它)
你需要做的是:
1)在web中添加一个键。配置,取决于生产或阶段服务器如下所示
<add key="HttpsServer" value="stage"/>
or
<add key="HttpsServer" value="prod"/>
2)在Global内部。Asax文件添加如下方法。
void Application_BeginRequest(Object sender, EventArgs e)
{
//if (ConfigurationManager.AppSettings["HttpsServer"].ToString() == "prod")
if (ConfigurationManager.AppSettings["HttpsServer"].ToString() == "stage")
{
if (!HttpContext.Current.Request.IsSecureConnection)
{
if (!Request.Url.GetLeftPart(UriPartial.Authority).Contains("www"))
{
HttpContext.Current.Response.Redirect(
Request.Url.GetLeftPart(UriPartial.Authority).Replace("http://", "https://www."), true);
}
else
{
HttpContext.Current.Response.Redirect(
Request.Url.GetLeftPart(UriPartial.Authority).Replace("http://", "https://"), true);
}
}
}
}
IIS7模块将允许您重定向。
