A note about Laravel Route redirection
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]

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

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.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.
