url-rewrite - 用 apache rewrite 和 php 实现单一入口时候出现的一个问题
我想用 Apache 的 rewrite 在 php 中实现单一入口,把所有的请求都重定向到 index.php,然后分析 $_SERVER['REQUEST_URI'],构建路由功能。
在使用时候时候出现了一个问题,请求其他的地址,比如 http://localhost/a/b/c 可以获得结果
array (size=4) 0 => string '' (length=0) 1 => string 'a' (length=1) 2 => string 'b' (length=1) 3 => string 'c' (length=1)
但是如果是 http://localhost/index 就会提示404错误,这是为什么啊
index.php大概是这样
<?php ........ function analysisUri() { var_dump(explode('/', $_SERVER['REQUEST_URI'])); } echo $_SERVER['REQUEST_URI']; analysisUri(); ........
virtualhost配置是这样
这个rewrite规则是从网上找到的
DocumentRoot /home/www <directory></directory> Options FollowSymLinks AllowOverride None #AllowOverride All <ifmodule mod_rewrite.c> RewriteEngine on RewriteBase / #不显示index.php RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L] #RewriteRule ^(.*)$ index.php?$1 [QSA,L] </ifmodule> <directory></directory> Options Indexes FollowSymLinks MultiViews AllowOverride None #AllowOverride All Order allow,deny allow from all DirectoryIndex index.php index.html index.htm

DocumentRoot /home/www <directory></directory> Options FollowSymLinks AllowOverride None #AllowOverride All <ifmodule mod_rewrite.c> RewriteEngine on RewriteBase / #不显示index.php RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L] #RewriteRule ^(.*)$ index.php?$1 [QSA,L] </ifmodule> <directory></directory> Options Indexes FollowSymLinks MultiViews AllowOverride None #AllowOverride All Order allow,deny allow from all DirectoryIndex index.php index.html index.htm
你的规则有问题。
RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
行不通的,正确的应该是 RewriteRule ^(.*)$ index.php?$1 [QSA,PT,L]
。?
才会吧后面的 $1
传给 index.php,而 /
告诉 apache 查找 index.php/
目录下的 index 文件,自然是 404。
你可以添加如下配置到 httpd.conf,调试 mod_rewrite,通过查看 rewrite.log 文件可以知道通过 rewrite 得到的路径到底是什么,完成调试后移除这个配置,否则会有些性能安全方面的影响。
# 输出调试信息到 rewrite.log <ifmodule mod_rewrite.c> RewriteLog "/var/log/apache2/rewrite.log" RewriteLogLevel 3 </ifmodule>
http://httpd.apache.org/docs/2.2/mod/...
另外,rewrite 规则完全没有必要写道 httpd.conf 里面,使用 .htaccess 比较好。
httpd.conf
DocumentRoot /home/www <directory></directory> Options FollowSymLinks AllowOverride None #AllowOverride All <directory></directory> Options Indexes FollowSymLinks MultiViews AllowOverride None #AllowOverride All Order allow,deny allow from all DirectoryIndex index.php index.html index.htm
/home/www/.htaccess
<ifmodule mod_rewrite.c> RewriteEngine on #不显示index.php RewriteBase / RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?$1 [QSA,PT,L] </ifmodule>
RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.
