IfDefine和RewriteBase不能很好地协同工作 [英] IfDefine and RewriteBase doesn't work well together

问题描述

当我使用此代码时，它可以正常工作:

When I use this code, it works just okay:

<IfDefine ${ServerBase}>
    RewriteBase ${ServerBase}
</IfDefine>

但是当我添加它时，它总是使用RewriteBase \，这不是我想要的.

But when I add this, it always uses RewriteBase \ which was not what I want.

<IfDefine !${ServerBase}>
    RewriteBase /
</IfDefine>

条件已经不同.定义ServerBase时之一，而未定义ServerBase时之一.如何在RewriteBase中使用IfDefine else模式?

The condition was already different. One of them when ServerBase is defined and one of them is when ServerBase is NOT defined. How can I use IfDefine else pattern with RewriteBase?

推荐答案

IfDefine检查是否定义了参数.它不会检查它的值.

IfDefine checks whether a parameter is defined or not. It doesn't check it's value.

您需要将其用作:

<IfDefine ServerBase>
    RewriteBase ${ServerBase}
</IfDefine>

<IfDefine !ServerBase>
    RewriteBase /
</IfDefine>

请注意使用ServerBase而不是${ServerBase}.
