nginx下基于ThinkPHP框架的网站url重写
nginx下的基于thinkphp的应用的url重写,需了解thinkphp的各种url格式参数的处理逻辑以及nginx重写的原理。简单点说,无论哪种url格式,nginx都需要执行ThinkPHP下的应用单一入口文件,然后将各种url格式按照一定的格式规则进行进行参数化处理,最终执行指定模块与控制器;这个过程用户是看不到的,用户只能看到各种规则的url,这些url的规则如下:#第一种 普通get多参数方式<br> htt://www.jb100.net/index.php?m=Info&a=usrInfo<br> <br> #第二种 pathinfo方式<br> htt://www.jb100.net/index.php/Info/usrInfo<br> #带有get的其他变量<br> htt://www.jb100.net/index.php/Info/usrInfo/Id/1#第三种 普通get单参数方式 ThinkPHP中又称”兼容模式“
htt://www.jb100.net/index.php?s=Info/usrInfo
#带有get的其他变量
htt://www.jb100.net/index.php?s=Info/usrInfo/Id/1

/*
#当然这三种模式还可以附带文件后缀
#其实合并起来也就3种
#附带后缀只是上述三种规则的细微变化
#TinkPHP框架核心代码获取到以上三种模式的参数后
#会进行特定的处理 带不带后缀 带哪种后缀 均可配置
#也就是如下几种规则
*/#第一种<br> htt://www.jb100.net/index.php/Info/usrInfo.html<br> #第二种<br> htt://www.jb100.net/index.php?s=Info/usrInfo.html======

什么是pathinfo?pathinfo是php的功能,nginx并没有pathinfo功能,在php中书写如下代码:<?php <br /> <br> print_r(pathinfo('http://www.jb100.net/test/index.txt'));<br> <br> ?>结果:Array<br> (<br>  [dirname] => http://www.jb100.net/test<br>  [basename] => index.txt<br>  [extension] => txt<br>  [filename] => index<br> )通过以上运行结果,可以看到打印出来的数组key字段已经很明显的标示出其意义来了。

ThinkPHP就采用了这种思想,将单一入口的url传参格式化,典型的基于ThinKPHP的url示例如下:http://www.jb100.net/index.php/Usr/UsrInfo简单点理解,上述格式化的url形式就是ThinkPHP需要支持的pathinfo路径模式。对这个种格式化的url进行稍微解释,访问这个么一个地址,对基于ThinkPHP框架的网站来说,实际需要执行的就是网站根目录下的index.php文件,而该url中后面的/Usr/UsrInfo则被作为mvc思路中的功能模块参数与控制器参数,转换为普通get方式传参则上述url就要变为:http://www.jb100.net/index.php?m=Usr&a=UsrInfo当然,get参数的变量该例子中一个是m一个是a,这个变量名在ThinkPHP中是可以改变的,这就需要依据具体的基于ThinkPHP的应用的模块规划与喜好了。

有了这种思路,nginx的url重写就有了最原始的写法了,对于上述pathinfo的格式化url,nginx在不做url重写时会把它当做一个路径来执行,一般来说没有谁会吃多了撑得在网站根目录下建立一个名字叫index.php的目录(注意:是目录,不是一般意义上的文件),所以第一种url重写出现了:

#一下是nginx配置文件的代码片段 仅书写url重写的部分location / {<br>  root /var/www;<br>  index index.html index.htm index.php;<br>  if (!-d $request_filename) {<br>  rewrite ^/(.*)/(.*)/*$  /index.php?m=$1&a=$2  last;<br>  break;<br>  }<br> }但问题出现了,基于ThinkPHP的应用不仅仅只有上述例子中的这种pathinfo模式,现在变成这样的了:(为了便于解说,称如下代码段为“url示例”,后方提到“url示例”就是指此处的三种url格式)

#第一种,未隐藏index.php 但url路径中有.html后缀http://www.jb100.net/index.php/Usr/UsrInfo.html#第二种,隐藏脚本文件index.phphttp://www.jb100.net/Usr/UsrInfo<br> 或<br> http://www.jb100.net/Usr/UsrInfo/#第三种,需要在访客看到的网址中隐藏掉index.php,且带.html后缀http://www.jb100.net/Usr/UsrInfo.html再了解下ThinkPHP中处理url的各种逻辑,ThinkPHP对传参进行了多种判定与处理,除了get方式传递不同的get变量作为mvc中的控制变量外,还有一个“兼容模式”的传参规则,也就是如下:

#ThinkPHP可以处理的传参形式http://www.jb100.net/index.php?s=/Usr/UsrInfo这种传参形式依然是get方式传参,但省略了多个get参数。ThinkPHP框架会对获取到的get变量$_GET['s']进行处理,从其中提取出mvc所需要的各个控制变量。

所以又一种nginx的url重写出现了:location / {<br>  root /var/www;<br>  index index.html index.htm index.php;<br>  if (!-e $request_filename) {<br>  rewrite ^(.*)$ /index.php?s=$1 last;<br>  break;<br>  }<br> }那么,现在需要同时兼容上述url示例中的三种格式又出问题了。最后解决方法如下:location / {<br>  root /var/www;<br>  index index.html index.htm index.php;<br>  if (!-e $request_filename) {<br>  rewrite ^/index.php(.*)$ /index.php?s=$1 last;<br>  rewrite ^(.*)$ /index.php?s=$1 last;<br>  break;<br>  }<br> }转载原文地址:http://www.jb100.net/html/content-28-519-1.html

Guidance and Examples: Learn to implement the selection sort algorithm in Java Guidance and Examples: Learn to implement the selection sort algorithm in Java Feb 18, 2024 am 10:52 AM

Java Selection Sorting Method Code Writing Guide and Examples Selection sorting is a simple and intuitive sorting algorithm. The idea is to select the smallest (or largest) element from the unsorted elements each time and exchange it until all elements are sorted. This article will provide a code writing guide for selection sorting, and attach specific Java sample code. Algorithm Principle The basic principle of selection sort is to divide the array to be sorted into two parts, sorted and unsorted. Each time, the smallest (or largest) element is selected from the unsorted part and placed at the end of the sorted part. Repeat the above
