isapi rewrite 设置问题

[pccc1984]

比如我要将 blog.aa.com/aa 转到 www.aa.com/blog/index.aspx?id=aa 上要怎么做?

用UrlReWriter可以实现,不过要修改下它的源代码

1.BaseModuleRewriter.cs


protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication) sender;
Rewrite(app.Request.Path, app);
}

改为


protected virtual void BaseModuleRewriter_AuthorizeRequest(object sender, EventArgs e)
{
HttpApplication app = (HttpApplication) sender;
Rewrite(app.Request.Url.AbsoluteUri, app);
}


就是将 app.Request.Path 替换成了 app.Request.Url.AbsoluteUri

2.ModuleRewriter.cs


for(int i = 0; i < rules.Count; i++)
{
// get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory)
string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$";

// Create a regex (note that IgnoreCase is set)
Regex re = new Regex(lookFor, RegexOptions.IgnoreCase);

// See if a match is found
if (re.IsMatch(requestedPath))
{
// match found - do any replacement needed
string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo));

// log rewriting information to the Trace object
app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl);

// Rewrite the URL
RewriterUtils.RewriteUrl(app.Context, sendToUrl);
break; // exit the for loop
}
}

改为


for(int i = 0; i < rules.Count; i++)
{
// get the pattern to look for, and Resolve the Url (convert ~ into the appropriate directory)
string lookFor = "^" + rules[i].LookFor + "$";

// Create a regex (note that IgnoreCase is set)
Regex re = new Regex(lookFor, RegexOptions.IgnoreCase);

// See if a match is found
if (re.IsMatch(requestedPath))
{
// match found - do any replacement needed
string sendToUrl = RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, re.Replace(requestedPath, rules[i].SendTo));

// log rewriting information to the Trace object
app.Context.Trace.Write("ModuleRewriter", "Rewriting URL to " + sendToUrl);

// Rewrite the URL
RewriterUtils.RewriteUrl(app.Context, sendToUrl);
break; // exit the for loop
}
}

将

string lookFor = "^" + RewriterUtils.ResolveUrl(app.Context.Request.ApplicationPath, rules[i].LookFor) + "$";

改成了

string lookFor = "^" + rules[i].LookFor + "$";


完成这2处改动之后重新编译项目，将生成的dll复制到bin目录下。

修改完了这后，我们再把此 UrlRewriter.dll COPY 到我们项目的Bin目录下。
1。请确定你的域名是支持泛解析的。然后你的网站为默认网站，否则将不能实现（至少我现在还没有找到好办法）
2。在IIS配置：在IIS\你的站点\属性\主目录\配置\映谢 在通配符应用程序配置处插入一个新的映谢。把可执行文件设为和上面ASPX页面同样的配置即可（注意不要勾选 “确定文件是否存在”）。（用处就是使所有请求通过 asp.net 的ISAPI来处理，只有这样才能对所有地址进行重写嘛。）
3。查看下你的网站主机头，里面的第一个主机头值必须为空，否则会出现错误的请求。后面就随你加了，看你想绑定多少域名了。
4。最后改写你的 web.config 文件。
把上节中说到的
<httpHandlers>
<add verb="*" path="*.aspx" type="URLRewriter.RewriterFactoryHandler, URLRewriter" />
<add verb="*" path="*.html" type="URLRewriter.RewriterFactoryHandler, URLRewriter" />
</httpHandlers>
改为：
<httpModules>
<add type="URLRewriter.ModuleRewriter, URLRewriter" name="ModuleRewriter" />
</httpModules>
（就是改用HTTP 模块来执行重写，而不用HTTP 程序，否则无法重写地址前面。）
然后就来修改我们的重写正则了：
<RewriterRule>
<LookFor> http://blog\.aa\.com/(.*) </LookFor>
<SendTo> ~/blog/index.aspx?id=$1 </SendTo>
</RewriterRule>


如果你的二级域名也要变动
<RewriterRule>
<LookFor> http://(.*)\.aa\.com/(.*) </LookFor>
<SendTo> ~/$1/index.aspx?id=$2 </SendTo>
</RewriterRule>
