是否可以使用ColdFusion重写URL？ [英] Is it possible to rewrite url using ColdFusion?

问题描述

我需要生成用户友好的网址。我在IIS上。

I have got a requirement for generating user friendly urls.I am on IIS.

我的动态网址如下，

www.testsite.com/blog/article.cfm?articleid=4432

客户需要网址应如下所示

Client wants the urls should look like

www.testsite.com/blog/article_title

我知道这可以使用IIS URL rewiter 2.0轻松完成。

I know this can be easily done using IIS URL rewiter 2.0.

但客户只想使用ColdFusion。他给出的基本想法，

But the Client wants to do it using ColdFusion only. Basic idea he given like,

1. 用户将点击网址 www.testsite.com/blog/article_title


2. 我需要使用网址中的article_title获取文章ID。


3. 使用ID调用article.cfm页面并将输出加载到cfsavecontent，然后将该输出传递给浏览器。

但我不认为它可能在应用程序服务器级别。 IIS将如何理解我们用户友好的URL。或者我错过了一些重要的事情？是否可以在应用程序服务器级别使用ColdFusion进行？

But I do not think its possible at application server level. How IIS will understand our user friendly urls . OR am I missing something important? Is it possible to do it using ColdFusion at application server level?

推荐答案

首先，我讨厌建议重新发明轮子。网络服务员这样做并做得很好。

First, I hate to recommend reinventing the wheel. Webservers do this and do this well.

Cold Fusion可以用＃cgi.path_info＃做类似的事情。亚当塔特尔在这里解释说，你可以跳过一些箍：我可以在IIS中没有URL重写器的'友好'网址吗？。

Cold Fusion can do something like this with #cgi.path_info#. You can jump through some hoops as Adam Tuttle explains here: Can I have 'friendly' url's without a URL rewriter in IIS?.

选项＃2：我最喜欢的：OnMissingTemplate ..

Option #2: My Favorite: OnMissingTemplate..

仅适用于Application.cfc的用户（我很确定.cfm与onMissingTemplate没有对应关系。）

Only available to users of Application.cfc (I'm pretty sure .cfm has no counterpart to onMissingTemplate).

您可以在application.cfc中使用此功能，所有受影响的页面都会在此事件中抛出任何缺失的网址。然后你可以放置

You can use this function within application.cfc and all affected pages will throw any "missing" urls at this event. You can then place

<cffunction name="onMissingTemplate">
        <cfargument name="targetPage" type="string" required=true/>
        <!--- Use a try block to catch errors. --->
        <cftry>
                <cfset local.pagename = listlast(cgi.script_name,"/")>
                <cfswitch expression="#listfirst(cgi.script_name,"/")#">
                    <cfcase value="blog">
                        <cfinclude template="mt_blog.cfm">
                        <cfreturn true />
                    </cfcase>
                </cfswitch>
                <cfreturn false />
                <!--- If no match, return false to pass back to default handler. --->
                <cfcatch>
                      <!--- Do some error logging here --->
                      <cfreturn false />
                </cfcatch>
        </cftry>
</cffunction>

mt_blog.cfm 可以包含以下内容：如果你的网址就像/blog/How-to-train-your-flea-circus.cfm

mt_blog.cfm can have contents like, if your url is say just like /blog/How-to-train-your-flea-circus.cfm

<!--- get everything after the slash and before the dot --->
<cfset pagename = listfirst(listlast(cgi.script_name,"/"),".")>

<!--- you may probably cache queries blog posts --->
<cfquery name="getblogpost">
  select bBody,bTitle,bID
    from Blog
   where urlname = <cfqueryparam cfsqltype="cf_sql_varchar" value="#pagename#">
</cfquery>

<!--- This assumes you will have a field, ex: urlname, that has a url-friendly format to match
      to. The trouble is that titles are generically, in most blogs, changing every special char
      to - or _, so it's difficult to change them back for this sort of comparison, so an add'l
      db field is probably best. It also makes it a little easier to make sure no two blogs have
      identical (after url-safe-conversion) titles. --->

...

或者如果你使用像/ blog /这样的网址173_How-to-train-your-flea-circus.cfm（其中173是帖子ID）

Or if you use a url like /blog/173_How-to-train-your-flea-circus.cfm (where 173 is a post ID)

<!--- get everything after the slash and before the dot --->
<cfset pageID = listfirst(listlast(cgi.script_name,"/"),"_")>

<!--- you may probably cache queries blog posts --->
<cfquery name="getblogpost">
  select bBody,bTitle,bID
    from Blog
   where bID = <cfqueryparam cfsqltype="cf_sql_integer" value="#pageID#">
</cfquery.
