提起过滤器以迫使ssl [英] Lift filter to force ssl

问题描述

在struts应用程序中，我有一个过滤器，用于强制某些页面仅通过重定向通过https访问.我正在考虑将其移植为举升机，所以我的问题是:在这种环境下，是否存在举升"方式来实现这种过滤器，或者它与struts类似/相同?谢谢

in a struts application, I have a filter that forces certain pages to be accessed only over https via redirection. I'm thinking in porting it to lift so my question is: In the this environment, is there a "lift" way to implement such filter or is it similar/the same as in struts ? Thanks

推荐答案

在Lift中，SiteMap定义了页面访问规则.您可以创建一个SiteMap条目，该条目在某些页面上执行重定向到https站点的操作:

In Lift, the SiteMap defines the rules for page access. You can create a SiteMap entry that does a Redirect to the https site on certain pages:

// create an object that does a redirect to the https server if the
// request is on http
object RequireSSL extends Loc.EarlyResponse(
  () => {
    for {
      r <- S.request
      lowLevelReq <- Box !! r if lowLevelReq.scheme == "http"
    } {
      S.redirectTo("https://"+lowLevelReq.serverName+lowLevelReq.contextPath)
    }
    Empty
  })

// Build SiteMap
def entries = (Menu("Home") / "index") ::
(Menu("Secure") / "secure" >> RequireSSL) ::
Nil
