在写RewriteRule准备匹配url中的问号及后面的参数时，怎么弄都无法成功。正则的写法经过测试是正确的，问号也已经转义?后面的字符串，如下：QSA|qsappendWhenthereplacementURIcontainsaquerystring,thedefaultbehaviorofRewriteRuleistodiscardtheexistingquerystring,andreplaceitwiththenewlygeneratedone.Usingthe[QSA]flagcausesthequerystringstobecombined.Considerthefollowingrule:RewriteRule"/pages/(.+)""/page.php?page=123-thatis,theexistingquerystringwillbediscarded.所以，解决写法示例：RewriteRule^/(.+)$index.php?
在写RewriteRule准备匹配url中的问号及后面的参数时，怎么弄都无法成功。正则的写法经过测试是正确的，问号也已经转义?，可还是不行。
百度查询了下，RewriteRule 不会去匹配问号?后面的字符串，如下：
QSA|qsappend
When the replacement URI contains a query string, the default behavior of
RewriteRuleis to discard the existing query string, and replace it with the newly generated one. Using the [QSA] flag causes the query strings to be combined.Consider the following rule:
RewriteRule "/pages/(.+)" "/page.php?page=$1" [QSA]With the [QSA] flag, a request for
/pages/123?one=twowill be mapped to/page.php?page=123&one=two. Without the [QSA] flag, that same request will be mapped to/page.php?page=123- that is, the existing query string will be discarded.
所以，解决写法示例：
RewriteRule ^(w{2,30})/(.+)$ index.php?controller=$1&action=$2 [QSA]
可以把 /member/select?id=10 重写成 /controller=member&action=select&id=10
