Apache/mod_rewrite> Tomcat编码%26和"&"

Question

Apache是​​我的Web应用程序的前端,然后我使用mod_rewrite将请求代理到J​​Boss.到目前为止,这听起来很标准,但我遇到的问题是:如果我通过jboss @直接访问应用程序http://localhost:8080/app/page?raw=foo%26bar&page=1:

request.getParameter("raw") = foo&bar

如果我通过Apache @访问该应用程序 http://localhost/foo%26bar&page=1

request.getParameter("raw") = foo

所以在这个过程中的某个地方,它%26会丢失并被替换为一个&用于切换原始变量的东西.

这是我的Apache重写规则.

RewriteRule ^/(.*) \
    http://localhost:8080/app/home?raw=$1 [L,P]

Apache访问日志显示: http://localhost/foo%26bar&page=1

重写日志显示: http://localhost:8080/app/home?raw=foo&bar&page=1

但我希望请求是: http://localhost:8080/app/home?raw=foo%26bar&page=1

我很确定这也会出现斜杠/,对我来说这是某种编码问题.有没有办法代理URL未触动？似乎无法想出这个.

编辑:

首先我要说的是感谢Gumbo给我一些非常好的建议!基于这些建议,我已经简化了我的Apache配置以进行测试.

这就是它的样子:

ServerRoot "C:/apps/xampplite/apache"
Listen 80

LoadModule rewrite_module modules/mod_rewrite.so
LoadModule log_config_module modules/mod_log_config.so

ServerAdmin postmaster@localhost
ServerName localhost:80
DocumentRoot "C:/apps/xampplite/htdocs"
ErrorLog "logs/error.log"
LogLevel debug
DefaultType text/plain

<IfModule log_config_module>
    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
    LogFormat "%h %l %u %t \"%r\" %>s %b" common

    <IfModule logio_module>
      LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio
    </IfModule>
    CustomLog "logs/access.log" combined
</IfModule>

RewriteEngine On    
RewriteLog "C:/apps/xampplite/apache/logs/rewrite.log"
RewriteLogLevel 9 
RewriteMap escape int:escape
RewriteRule ^/(.*) http://localhost:8080/app/home?raw=${escape:$1} [L,P]

以下是我采取的步骤:启动Apache,转到

http://localhost/foo%26bar&page=1

在我的网络浏览器中,停止Apache.

访问日志条目:

有趣的是,访问日志中的第一个条目显示了%26,它在重写日志的第一个条目中消失了.

仍然对这个感到困惑......

尝试使用NE标志来防止该字符转义：

\n\n

RewriteRule ^/(.*) http://localhost:8080/app/home?raw=$1 [NE,L,P]\n

\n\n\n\n

编辑\xc2\xa0\xc2\xa0\xc2\xa0\xc2\xa0 我想我错了。您需要强制转义，而不是阻止值被转义。尝试使用内部转义函数：

\n\n

RewriteMap escape int:escape\nRewriteRule ^/(.*) http://localhost:8080/app/home?raw=${escape:$1} [L,P]\n

\n
