Tuckey urlrewrite，如何检查是否存在指定名称的参数？

Question

似乎以下配置不起作用

<rule>
    <condition type="parameter" name="direct" operator="notequal"></condition>
    <from>^/payment.html$</from>
    <set name="google-analytics-uri">/shop/payment-direct</set>
</rule>

输入网址：_http：//somesite.com/payment.html？direct = value 结果＆＃39; google-analytics-uri＆＃39;是空的。

Answer 1

找到解决方案（在调试库源之后：）

<rule>
    <condition type="parameter" name="direct" operator="notequal">^$</condition>
    <from>^/payment.html$</from>
    <set name="google-analytics-uri">/shop/payment-direct</set>
</rule>
