一系列重写规则无尾页[L]标志 [英] A series of rewriterule without Last [L] Flag
问题描述
更新： 今天我有点找出问题是：现在就来看看小版本
UPDATE: today I kind of find out what the problem is : now take a look at smaller version
RewriteCond %{REQUEST_FILENAME} (.+)
RewriteRule first /landingpage1.php [R,ENV=lang:hi]
RewriteCond %{REQUEST_FILENAME} (.+)
RewriteRule second /landingpage2.php?id=%1&%{ENV:lang} [R,L]
我的htaccess的文件位置是/ WWW / H /文件夹 如果我输入localhost / H / firstsecond，它返回本地主机/ landingpage1.php，图案不满意的4号线 但是如果我输入localhost / H /第一/第二，问题开始，它=土地在localhost / landingpage2.php ID =本地主机/ landingpage1.php和放大器;喜，居然有一次，只是有一次我不知道我怎么了，发现实验过程中，将localhost / H /第一/第二个URL，它与第一个重写规则行类似本地主机/ landingpage1.php //秒，ofcourse这样，我们看到第二行的工作重新定向， 我已经看到了这种用别名行为定向过，如果有一些文件夹跟踪到您的网址，它增加了余下的部分到最后重定向的URL与查询字符串。
my htaccess file location is /www/h/ folder if I type localhost/h/firstsecond, it returns localhost/landingpage1.php , pattern is not satisfied on 4th line but if I type localhost/h/first/second, problem starts , it = lands on localhost/landingpage2.php?id=localhost/landingpage1.php&hi , actually one time, just one time I do not know how, I find out during experiment that with localhost/h/first/second url , it redirected with first rewriterule line something like localhost/landingpage1.php//second , and ofcourse this way we see second line works , I have seen this kind of behavior with Alias "redirect" too, if there is something folder trail into your url , it adds remaining part into final redirected url along with query string.
所以当本地主机/ H / firstsecond工作正常，但本地主机/ H /第一/第二不，我知道大概接近就知道是怎么回事。
so when localhost/h/firstsecond works fine but localhost/h/first/second does not , i know probably close to know what is going on.
ARCHIEVE：
我想了解的行为一堆重写规则的规则没有最后标志 考虑我的htaccess的文件位置为localhost / H /（应用/ AMPPS / WWW / H）
I am trying to understand behaviour a bunch of rewriterule rules without Last flag Consider my htaccess file location is localhost/h/ ( Applications/AMPPS/www/h )
例1：
RewriteRule anchor/(.+) /hello [R,ENV=lang:hi]
RewriteRule anchor /anchor/guess [R]
RewriteRule /hello /yes [R]
如果我输入localhost / H /锚/文 那么我认为发生的是
If I enter localhost/h/anchor/text then what I think happen is
-
第一行重写规则锚/(.+）/你好[R，ENV =郎咸平：喜]的模式锚/(.+）的比赛，因此它重定向到localhost /打招呼，但因为有是不使用L标志，重定向到localhost /你好处于暂停状态，因此低于
First line RewriteRule anchor/(.+) /hello [R,ENV=lang:hi] 's pattern "anchor/(.+)" matches and so it redirects to localhost/hello , but as there is no L flag, redirection to localhost/hello is on hold ,thus it goes below
第二行的模式锚不与新的HTTP匹配：//本地主机/打招呼所以这将跳过
Line second's pattern "anchor" does not match with new http:// localhost/hello so this is skipped
事情似乎按照我虽然直到我看到下面的例子 实施例2：
Things seems as per I though untill I see example below Example 2:
RewriteRule foo/bar /tmp1/ [R]
RewriteRule foo/bar /tmp2/ [R]
RewriteRule (.+) /tmp3/ [R]
RewriteRule (.+) /tmp4/ [R]
RewriteRule hello /tmp6/ [R]
RewriteRule bar /tmp7/ [R]
RewriteRule hello /tmp8/ [R]
RewriteRule tmp7/ /tmp5/ [R]
相同htaccess文件的位置，我打本地主机URL / H /富/酒吧，
我认为出现这种情况
1.第一行的模式富/酒吧与URL匹配，因此它重定向到http：//本地主机/ TMP1 /，但因为没有L，它的搁置，它低于
same htaccess file location, I hit url localhost/h/foo/bar ,
I thought this happens
1. first line's pattern "foo/bar" matches with url , so it redirects to http:// localhost/tmp1/ , but as there is no L , its on hold , it goes below
第二行的模式富/酒吧不以http匹配：//本地主机/ TMP1 /，因此其跳过，（如果我删除除前两行的所有，我看到的最后重定向到http：//本地主机/ TMP1 /）
second line's pattern "foo/bar" does not match with http:// localhost/tmp1/ , so its skipped, ( if I remove all lines except first two , I see final redirects to http:// localhost/tmp1/)
第三行的模式匹配以http：//本地主机/ TMP1 /转身到http：//本地主机/ TMP3 /
third line's pattern match with http:// localhost/tmp1/ and turned to http:// localhost/tmp3/
第四条线的模式相匹配，重定向到http：//本地主机/ tmp4 /
fourth line's pattern matches, redirect to http:// localhost/tmp4/
第五行的你好不匹配的重定向仍然是http：//本地主机/ tmp4 /
fifth line's "hello" not matched redirects still is http:// localhost/tmp4/
而现在这件事自旋我心中最后的3小时是第六的路线栏中的匹配..和重定向到http：//本地主机/ tmp7 /（除去最后两行确认）怎么样？
and now which thing spin my mind for last 3 hrs is sixth's line "bar" matches .. and redirects to http:// localhost/tmp7/ ( remove last 2 lines to confirm ) how ?
第七的不匹配预期
第八行tmp7 /匹配以http：//本地主机/ tmp7 /然后终于重定向到http：//本地主机/ TMP5 /
eighth line tmp7/ matches with http:// localhost/tmp7/ and then finally redirects to http:// localhost/tmp5/
现在的问题是，为什么6'th行的酒吧的比赛，如果能与最古老的URL匹配输入（HTTP：//本地主机/富/条），那么它为什么在第二行相同的例子，为什么它不匹配没有在实施例1的第二行匹配？
now question is why 6'th line's "bar" matches and if it can match with oldest url entered (http:// localhost/foo/bar ) then why it did not match on second line of same example and why it did not matched in second line of example 1 ?
记住所有的目标模式指向文件夹之外（WWW的父母，使他们不能打回htaccess文件再次）
remember all target pattern point to outside of the folder ( in parent, www, so that they can not hit back to the htaccess file again )
推荐答案
首先，有很多细节都一个很好的问题。
First of all a very good question with lots of details.
如果您启用 RewriteLog ，你会发现其实这是可能出自这条线（当你请求的http：//本地主机/ H /第一/秒 URL）：
If you enable RewriteLog you will notice this is actually being caused by this line (when you request http://localhost/h/first/second URL):
add path info postfix: /landingpage1.php/second
这发生在你忽略→或 DPI （即放弃路径信息）从
This happens when you omit L or DPI (i.e. Discard Path Info) flags from RewriteRule.
这将表现良好，如果你使用的：
It will behave well if you use:
RewriteCond %{REQUEST_FILENAME} (.+)
RewriteRule first /landingpage1.php [R,DPI,ENV=lang:hi]
RewriteCond %{REQUEST_FILENAME} (.+)
RewriteRule second /landingpage2.php?id=%1&%{ENV:lang} [R,L]
