急!session问题

Jun 23, 2016 pm 02:21 PM

session url php

RewriteRule ^index.html&fun=000$ gyjw/check.php重写了url
我的登陆页面
<?php	session_start();	//使用session存储用户信息	if(isset($_POST["username"]))	{		$ss_user_id="";				//利用User累的IsValid()方法判断所输入的用户名和口令是否正确		require_once("user/UserClass.php");		$user=new User();		//如果正确,转到系统首页		if($user->IsValid($_POST["username"],$_POST["password"],$ss_user_id))		{			$_SESSION["ss_user_id"]=$ss_user_id;			echo "<script language='javascript'>";			echo " location='index.html';";			echo "</script>";		}		//如果不正确,转到登陆页面		else		{			echo "<script language='javascript'>";			echo " alert('用户名或密码错误');";      		echo "</script>";		}	}?>
Copy after login
主页的php
<?php	include 'http://localhost/gyjw/index.html&fun=000';?>//省略html部分
Copy after login
check.php
<?php  	if(! isset($_SESSION['ss_user_id']))	{   		echo "<script language='javascript'>";		echo "alert('您的用户无权进行此操作!');";		echo "top.location='login.html';";		echo "</script>"; 		exit;  	}?>
Copy after login
问题是登陆成功跳转至主页的时候,先跳转至check.php,之直接就显示了'您的用户无权进行此操作!',说明$_SESSION['ss_user_id']不存在了。然后如果修改了主页的php
<?php	include ("check.php");?>
Copy after login
就存在这个$_SESSION['ss_user_id']正常显示了主页内容。
麻烦各位大侠帮助解决!

check.php 中缺少 session_start();

check.php 中缺少 session_start();
呃,不小心删掉了,但不是这个问题。

check.php 中缺少 session_start(); 通过观察生成的session文件sess_...我发现如果include里面用的是check.php,就只会生成一个sess_,如果include里面放的http://localhost/gyjw/index.html&fun=000,就会生成两个sess_,其中一个是没有数据的,这是不是说明在跳转http://localhost/gyjw/index.html&fun=000的时候系统又重新生成了一个sess_,所以$_SESSION['ss_user_id']才没有值,要怎么解决呢?

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
