laravel session 自动更新疑惑
1.在登录的时候存储 session (userSession);
2.登录后编辑登录用户信息,编辑完成后并没有重新更新userSession;
3.但是在中间件里,获取session的时候却可以得到编辑后的信息 (获取方式:session('userSession'));
不明白这里是为什么?还是在前边处理的时候哪里有问题....
求解!

找到一遍文章 里边这样写:
查看调用相关的代码。laravel编译后,在bootstrap/compiled.php中
<code> class Middleware implements HttpKernelInterface { ... public function handle(Request $request, $type = HttpKernelInterface::MASTER_REQUEST, $catch = true) { $this->checkRequestForArraySessions($request); if ($this->sessionConfigured()) { $session = $this->startSession($request); // 启动session $request->setSession($session); } $response = $this->app->handle($request, $type, $catch); // 调用controller的method if ($this->sessionConfigured()) { $this->closeSession($session); //关闭session $this->addCookieToResponse($response, $session); } return $response; } ... protected function closeSession(SessionInterface $session) { $session->save(); // 保存session $this->collectGarbage($session); } } </code>
可以看见,在调用完controller之后,调用了session->save()的方法,来主动的保存session。这样session才能落地保存起来,如果在controller或者view里面写了exit;,那么session是不会被保存的,除非主动的写Session::save()才能手工的保存起来。(如果不知道函数调用情况,可以在controller中throw new Exception();,然后在/config/app.php的debug更改为debug=>true。可以看到函数的调用关系。)
但是原理还是不明白!!!因为测试的结果 并不是调用完每个controller 都会修改session。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
