Nginx中PATH_INFO的空值返回垃圾值 [英] Empty value to PATH_INFO in nginx returns junk value

问题描述

当nginx设置的PATH_INFO为空字符串时，从PHP访问它时出现一些垃圾字符.

When the PATH_INFO set by nginx is empty string, I get some junk character while accessing it from PHP.

这是我在nginx中设置PATH_INFO的方法:

This is how I set the PATH_INFO in nginx:

    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_param  PATH_INFO  $fastcgi_path_info;

如果路径信息具有一些非空值，则可以正常工作.我什至重新安装了nginx，但没有帮助. nginx版本是1.0.5(如果需要的话，我正在使用Ubuntu 11.10).

It works fine if the path info has some non-empty value. I even reinstalled nginx, but it didn't help. nginx version is 1.0.5 (I'm using Ubuntu 11.10, if at all it matters).

推荐答案

几天前的某个视图中我得到了同样的东西..因此，我将正则表达式更改为如下形式:

I got the same thing a view days ago .. therefore I changed the regexp to look like this:

fastcgi_split_path_info ^(.+\.php)(/.*)$;

并在其他行中添加了一个视图，以使其最有可能在Apache上运行.

And added a view other lines to make it work most likely to Apache.

这是我对文件 fastcgi_params

使用此配置，您将始终拥有PATH_INFO变量，而不是在f.e中如何完成.阿帕奇.

Using this configuration you always have the PATH_INFO variable instead of how it's done in f.e. Apache.

我使用过的某些脚本像这样检查(当然)不适用于我的配置:

Some of the scripts I used just checked like this what (of course) does not work with my configuration:

if (!isset($_SERVER['PATH_INFO']) { doSomething() }

我建议主要开发人员将其更改为此:

I adviced the main-developer to change it to this:

if (!isset($_SERVER['PATH_INFO'] || empty($_SERVER['PATH_INFO']) { doSomething() }

编辑:我找到了一个解决方案稍有不同的博客.我还没有测试过，但是看起来有点小;) http://www.jzxue.com/fuwuqi/http -iis-apache/201108/19-8538.html

I found a blog with a slightly different solution. I have not tested it yet, but it seems to be a bit smaller ;) http://www.jzxue.com/fuwuqi/http-iis-apache/201108/19-8538.html

set $path_info "";
set $real_script_name $fastcgi_script_name;
if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
set $real_script_name $1;
set $path_info $2;
}
fastcgi_param SCRIPT_FILENAME /var/html/$real_script_name;
fastcgi_param SCRIPT_NAME $real_script_name;
fastcgi_param PATH_INFO $path_info;
