1，确保apache支持 mod_rewrite 1）打开Apache2.2\conf\httpd.conf 搜索 LoadModule rewrite_module modules/mod_rewrite.so (Apache2是这个) 去掉前面的# 2）搜索AllowOverride None 替换为 AllowOverride All(注意，有好几个) 2，在 CI 根目录下新建立一个配置文件，命名为： .htaccess，文件内容如下： RewriteEngine on RewriteCond $1 !^(index\.php|images|robots\.txt) RewriteRule ^(.*)$ /index.php/$1 [L] 要注意 /index.php/$1 要根据你目录(Web 目录，比如 http://www. 34ways .com/index.php)的实际情况来定，比如网站根目录是 /34ways/index.php 则要写成 /34ways/index.php/$1 注意： RewriteCond $1 !^(index\.php|images|robots\.txt) 这里是需要忽略的路径和文件，比如可以这样来写： RewriteCond $1 !^(index\.php|images|robots\.txt|theme) 3，修改

一、CodeIgniter是什么 CodeIgniter 是一套给 PHP 网站开发者使用的应用程序开发框架和工具包。它的目标是让你能够更快速的开发，它提供了日常任务中所需的大量类库，以及简单的接口和逻辑结构。简单来说就是一套开源的、轻量级的php框架二、CodeIgniter下载 http://codeigniter.org.cn/ ，下载后解压。三、CodeIgniter安装上一篇已经写过xampp环境搭建，https://www.cnblogs.com/qingqing-919/p/11132244.html，将解压后的CodeIgniter 复制，粘贴到xampp安装目录\xampp\htdocs文件夹下。四、测试CodeIgniter 是否安装成功启动xampp中apache服务，自动方法在搭建中已经说过。找到xampp安装目录，双击目录下的：xampp-control.exe ，启动xampp的控制台，在这个控制台中对Apache启动。浏览器中访问 http://localhost/CodeIgniter/index.php/Welcome（这里是我本机路径，如果存放路径不同需要改成跟自己本机一致）这样就安装成功了。来源： https://www.cnblogs.com/qingqing-919/p/11132402.html

去掉CodeIgniter URL中的index.php

CI默认的rewrite url中是类似这样的，例如你的CI根目录是在/CodeIgniter/下，你的下面的二级url就类似这样http://localhost /CodeIgniter/index.php/welcome。不太好看，怎么把其中的index.php取掉呢？ 1. 打开apache的配置文件，conf/httpd.conf ： LoadModule rewrite_module modules/mod_rewrite.so，把该行前的#去掉。搜索 AllowOverride None（配置文件中有多处），看注释信息，将相关.htaccess的该行信息改为AllowOverride All。 2. 在CI的根目录下，即在index.php，system的同级目录下，建立.htaccess，直接建立该文件名的不会成功，可以先建立记事本文件，另存为该名的文件即可。内容如下（CI手册上也有介绍）： 1 RewriteEngine on 2 RewriteCond $1 !^(index\.php|images|robots\.txt) 3 RewriteRule ^(.*)$ /index.php/$1 [L] 如果文件不是在www的根目录下，例如我的是：http://www.nowamagic.net/CodeIgniter/，第三行需要改写为RewriteRule ^

问题 I usually use something like: class User extends CI_Controller { public function save() { if($this->input->is_post()) { //my own method ...... } } } Is there any other way, eg. in Slim framework: post("/user/save", function() { ...... }); or in .Net MVC: [HttpPost] public ActionResult save(User model) { ...... } Or can CodeIgniter handle this in its route config file? Thanks for answer. 回答1: Codeigniter has no built-in support for REST. If you want it, you need to use third-party library or

http://drops.wooyun.org/papers/1449 原文链接：http://www.mehmetince.net/codeigniter-object-injection-vulnerability-via-encryption-key/ 0x00 背景大家好，Codeigniter 是我最喜爱的PHP框架之一。和别人一样，我在这个框架中学习了PHP MVC编程。今天，我决定来分析一下Codeigniter的PHP 对象注入漏洞。我在接下来的叙述中会把重点放在Codeigniter的Session会话机制上。所有我将会分析的method方法都在 CodeIgniter/system/libraries/Session.php 文件里。我在本研究过程中使用的是Codeigniter 2.1 版本。 0x01 Codeigniter Session会话机制 Codeigniter 使用PHP的序列化method方法来存储用户Session会话中的变量。但是Codeigniter Session会话机制并不像我们预期的那样工作。它把session会话的变量存在了客户端的cookie里面，大多数是在（服务器）硬盘上而不是用户COOKIE中。我不知道开发者们为什么这么设计。下面的叙述摘自codeigniter的文档 The Session class stores
