Apache/mod_rewrite> Tomcat編碼％26和「＆」

Question

Apache是​​我的web應用程序的前端，然後我使用mod_rewrite將請求代理到J​​Boss。到目前爲止，這聽起來很標準，但我遇到的問題是：如果我直接通過JBoss的訪問應用@http://localhost:8080/app/page?raw=foo%26bar&page=1：

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

如果我通過Apache訪問的應用程序@http://localhost/foo%26bar&page=1

request.getParameter("raw") = foo 

所以在某個地方，%26丟失，並被替換爲&，這會切斷原始變量。

這是我的Apache重寫規則。

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

Apache的訪問日誌顯示：http://localhost/foo%26bar&page=1

而重寫日誌顯示：http://localhost:8080/app/home?raw=foo&bar&page=1

但我想請求是：http://localhost:8080/app/home?raw=foo%26bar&page=1

我敢肯定，這也發生斜線/太對我來說這是一些編碼問題。有沒有辦法代理URL未觸動？似乎無法找出這一個。

編輯：

我想說的是第一件事，感謝你對濃湯給我一些很好的建議！基於這些建議，我簡化了我的Apache配置以用於測試目的。

這是什麼樣子：

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] 

下面是我所採取的步驟：啓動Apache，去

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

在我的網頁瀏覽器，停止Apache。

有趣的是在訪問日誌中的第一個條目顯示了％26並且它在重寫日誌的第一個條目中消失了。

仍然不解這個...

Answer 1

與NE flag嘗試，以防止該字符轉義：

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

---

編輯我覺得我得到的錯誤。而不是防止值被轉義，你需要強制轉義。與內部逃生功能試試：

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

Answer 2

這應該工作：

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

如應該這樣：

RewriteCond %{REQUEST_URI} ^/(.*) 
RewriteRule ^/(.*) http://localhost:8080/app/home?raw=%1 [L,P]
