laravel5 session的使用方法:
配置
session配置文件位于config/session.hpp 默认情况下使用session驱动为文件驱动,在生产环境中,建议使用memcache或者redis驱动以便获取更快的session性能。
其它Session相关问题
Laravel框架内部使用flash session键,所以你不应该通过该名称添加数据项到session。
如果你需要所有存储的session数据经过加密,在配置文件中设置encrypt配置为true。
session基本使用
获取session中的所有数据
$request->session()->all();
使用全局的PHP函数session来获取和存储session中的数据
从session中获取数据...
$value = session('key');
存储数据到session...
session(['key' => 'value']); $request->session()->put('key', 'value');
push 方法可用于推送数据到值为数组的session
$request->session()->push('user.teams', 'developers');
判断session是否存在指定的项
if ($request->session()->has('users')) { }
获取并删除数据
value=request->session()->pull('key', 'default');
删除session中的数据项
$request->session()->forget('key'); //删除指定数据项数据 $request->session()->flush(); //删除所有数据
重新生成sessionID
$request->session()->regenerate();
一次性数据
$request->session()->flash('status', 'Task was successful!');//该方法存储的session数据只在随后的HTTP请求中有效,然后将会被删除
如果你需要在更多请求中保持该一次性数据,可以使用reflash方法,该方法将所有一次性数据保留到下一个请求,如果你只是想要保存特定一次性数据,可以使用keep方法
request−>session()−>reflash();request->session()->keep(['username', 'email']);
View展示session数据
{{ Session::get('username') }}

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
