＊＊＊＊＊简单正则表达式问题

Question

本文需要对URL进行Rewrite操作：输入:www.ji.com/hot
转到:www.ji.com/hot.aspx输入:www.ji.com/hot_1
转到:www.ji.com/hot.aspx?pageno=1输入:www.ji.com/hot_2
转到:www.ji.com/hot.aspx?pageno=2
正则如何写呢？
<RewriterRule>
    <LookFor>www.ji.com/这块的正则如何写才能满足以上重写地址呢？</LookFor>
    <SendTo>www.ji.com/hot.aspx?pageno=$1</SendTo>
</RewriterRule>

Answer 1

输入中是否有“_”,如果有，replace（"_",".aspx?pageno="）;
  如果没有，  输入的str+“aspx”；要写代码只会用c#写。比较熟。
hope can help you

Answer 2

[code=C#]<RewriterRule>
    <LookFor>www.ji.com/hot_([0-9]{0,})</LookFor>
    <SendTo>www.ji.com/hot.aspx?pageno=$1 </SendTo>
</RewriterRule> 

Answer 3

由www.ji.com/hot怎么转到:www.ji.com/hot.aspx 这块大家不用关心。
大家只需要说明正则如何写才能满足上面的需求即可

Answer 4

只能满足www.ji.com/hot_
www.ji.com/hot_1这个www.ji.com/hot是无法满足的

Answer 5

这个只能满足www.ji.com/hot_ 
www.ji.com/hot_1 这个www.ji.com/hot是无法满足的

Answer 6

<RewriterRule> 
    <LookFor>www.ji.com/hot_([0-9]{0,})|www.ji.com/hot </LookFor> 
    <SendTo>www.ji.com/hot.aspx?pageno=$1|www.ji.com/hot.aspx?</SendTo> 
</RewriterRule> 
这个思路行不行？

Answer 7

<RewriterRule> 
    <LookFor>www.ji.com/hot_([0-9]{0,}) </LookFor> 
    <SendTo>www.ji.com/hot.aspx?pageno=$1 </SendTo> 
<LookFor>www.ji.com/hot </LookFor> 
<SendTo>www.ji.com/hot.aspx</SendTo> 
</RewriterRule> 

Answer 8

题目发清楚嘛！ 
你的需求是 www.ji.com/aaa_bbb 转到 www.ji.com/aaa.aspx?pageno=$bbb对不？
前面 www.ji.com 是固定的吧？aaa bbb动态的吧？<RewriterRule>
    <LookFor>www.ji.com/(.*?)_([0-9]{0,})</LookFor>
    <SendTo>www.ji.com/$1.aspx?pageno=$2</SendTo>
</RewriterRule>

Answer 9

这位仁兄，实现的是我要的结果，但是我想用一个
<LookFor>www.ji.com/hot_([0-9]{0,}) </LookFor> 
    <SendTo>www.ji.com/hot.aspx?pageno=$1 </SendTo> 
实现.另外:hot后面的下划线及后面的参数有可能没有.
<RewriterRule> 
    <LookFor>www.ji.com/hot这块的正则如何写才能满足以上重写地址呢？ </LookFor> 
    <SendTo>www.ji.com/hot.aspx?pageno=$1 </SendTo> 
</RewriterRule> 

Answer 10

<RewriterRule> 
<LookFor>www.ji.com/hot_{0,}([0-9]{0,}) </LookFor>
<SendTo>www.ji.com/hot.aspx?pageno=$1 </SendTo> 
</RewriterRule> hot后面的参数没有那就成了www.ji.com/hot.aspx?pageno=

Answer 11

这个无所谓的，我程序中判断了，若pageno什么也没有，我会返回0

Answer 12

<RewriterRule>
    <LookFor>^www.ji.com/hot(_([0-9]+))?$ </LookFor>
    <SendTo>www.ji.com/hot.aspx?pageno=$2 </SendTo>
</RewriterRule> 

Answer 13

<RewriterRule> 
    <LookFor>www.ji.com/hot_?(\d+)? </LookFor> 
    <SendTo>www.ji.com/hot.aspx?pageno=$1 </SendTo> 
</RewriterRule> 
或
<RewriterRule> 
    <LookFor>www.ji.com/hot(_(\d+)?) </LookFor> 
    <SendTo>www.ji.com/hot.aspx?pageno=$2 </SendTo> 
</RewriterRule> 

Answer 14

第一个应该不行：hot_?(\d+)? 这样它也匹配hot3，hot2等。
第二个：hot(_(\d+)?)我认为？应该在最外面：hot(_(\d+))？因为这样的话只要有_ 就必须后面有数字

Answer 15

上面的写法完全错误　.hot(_(\d+)?) 这样的表达式？
