发现问题
最近在做项目发现一个奇怪的现象,我的路由配置里有如下配置:
Route::group(array('prefix'=>'admin','before'=>'adminauth'),function(){ // 管理员登录 Route::get('/',function(){ return Redirect::to('admin/login'); }); Route::get('login','UserController@adminLogin'); }
目的是无论用户输入”admin”,还是”admin/login”都能跳转到登录界面。然而现实情况是输入”admin”之后,浏览器会无限重定向,firebug记录如下:
GET /public/admin/ 301 Moved Permanently GET admin 301 Moved Permanently GET admin 301 Moved Permanently GET /public/admin/ 301 Moved Permanently GET admin 301 Moved Permanently GET /public/admin/ 301 Moved Permanently GET admin 301 Moved Permanently ....
经过一番搜索后试验,终于得出结论,问题有两点:
1.public目录下正好有个admin目录,存放后台相关js和css
2.laravel自带的.htaccess的这样一条规则:
RewriteEngine On # Redirect Trailing Slashes... RewriteRule ^(.*)/$ /public/$1 [L,R=301] #注意这条 # Handle Front Controller... RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L]
解释一下原理:
访问public/admin目录时,apache会自动转成”public/admin/”的形式,而这种形式正好符合重写的规则,又被重写回”public/admin”的形式。因为public/admin目录确实存在,所以请求根本不会到达index.php。
所以故事就是这样,因为301那条规则的存在,无限重定向产生了。
解决方案:
1.不要把public目录下已有的目录名做为路由地址
2.301规则前加一条”RewriteCond %{REQUEST_FILENAME} !-d”,但是这样会使该目录被直接访问。建议生产环境中关掉apache的autoindex模块(呃,我发现我用的wamp关掉这个模块apache就启动不了了- -!)。
补充:
经过一些实验,建议将.htaccess文件改成如下:
RewriteEngine On # Redirect Trailing Slashes... RewriteCond %{REQUEST_FILENAME} !-d #防止真实目录导致循环重定向 RewriteRule ^(.*)/$ /public/$1 [L,R=301] # Handle Front Controller... #RewriteCond %{REQUEST_FILENAME} !-d #防止用户直接打开真实目录 RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L]

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 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.

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 remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

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.
