Codeigniter是一個(gè)很棒的PHP框架，有朋友問(wèn)IIS7下的Codeigniter的重寫去掉index.php應(yīng)該怎么做，在IIS7之前的時(shí)代，用ISAPI_REWRITE模塊加載httpd.ini是可以實(shí)現(xiàn)重寫和去掉index.php的，現(xiàn)在大部分windows服務(wù)器都升級(jí)為IIS7，重寫方法也就不一樣了。下面就介紹一下再IIS6、IIS7、apache和nginx下的解決辦法。

IIS 7使用Urlrewrite方法：修改web.config

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="OrgPage" stopProcessing="true">
                    <match url="^(.*)$" />
                    <conditions logicalGrouping="MatchAll">
                    <add input="{HTTP_HOST}" pattern="^(.*)$" />
                    <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                    </conditions>
                    <action type="Rewrite" url="index.php/{R:1}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>    
</configuration>

apache使用.htaccess重寫、去掉index.php方法

//保護(hù)系統(tǒng)路徑的寫法，在RewriteCond規(guī)則中寫入開(kāi)放的路徑
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond $1 !^(index\.php|sitemap\.xml|robots \.txt|assets)
    RewriteRule ^(.*)$ /index.php/$1
</IfModule>

//不保護(hù)系統(tǒng)路徑的寫法
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI} ^/system.*
    RewriteRule ^(.*)$ index.php?/$1 [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ /index.php?/$1 [L]
</IfModule>

Nginx的rewrite方法：

location / {
                root   $wwwroot;
                index  index.html index.htm index.php;
                #rewrite規(guī)則如下：
                rewrite ^/$ /index.php last;
                rewrite ^/(?!index\.php|robots\.txt|static)(.*)$ /index.php/$1 last;
                }

                location ~ ^(.+\.php)(.*)$ {
                root           $wwwroot;

                fastcgi_index        index.php;
                fastcgi_split_path_info ^(.+\.php)(.*)$;
                fastcgi_param        SCRIPT_FILENAME        $document_root$fastcgi_script_name;
                fastcgi_param        PATH_INFO                $fastcgi_path_info;
                fastcgi_param        PATH_TRANSLATED        $document_root$fastcgi_path_info;
                #注意：去臨時(shí)文件夾內(nèi)找到你的php-cgi，也可能php-cgi.sock不是這么個(gè)名字。
                fastcgi_pass    unix:/tmp/php-cgi.sock;
                include        fastcgi_params;
}

老版本IIS的URL_REWRITE模塊（ISAPI_REWRITE）方法：

[ISAPI_Rewrite]
RewriteRule /httpd(?:\.ini|\.parse\.errors) / [F,I,O]
RewriteCond URL ^/(?!js|images|style|uploadfile|index\.php|robots\.txt|favicon\.ico).*
RewriteRule /(.*) /index.php/$1 [I,L]
