HomeBackend DevelopmentPHP Tutorialurl-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

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

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
