thinkphp引入一个公共类,如何在其他方法里面不需要再实例化调用

<?phpnamespace Index\Controller;use Think\Controller;use Com\Wechat;class WuyeController extends CheckController {   protected function _initialize(){ 		$token = 'weixin'; //微信后台填写的TOKEN 		$wechat = new Wechat($token); 	} 	public function index(){		 $weObj->text("hello, I'm wechat")->reply();		 //在这里不能调用上面实例化的类		 //如何操作才可以使用	 }	    public function test(){		 $weObj->text("hello, I'm wechat")->reply();		 //在这里不能调用上面实例化的类		 //如何操作才可以使用    }}

这就是个类 创建一个public 的变量....

怎么创建呢,我都试过好像不能继承

class WuyeController extends CheckController {   protected $wechat;   protected function _initialize(){         $token = 'weixin'; //微信后台填写的TOKEN         $this->wechat = new Wechat($token);     }     public function index(){         $this->weObj->text("hello, I'm wechat")->reply();     }          public function test(){         $this->weObj->text("hello, I'm wechat")->reply();    }}

谢谢回复,但是还是不行,提示Call to a member function text() on a non-object

那就是没有实例化成功

我用的类库是这个

https://github.com/dodgepudding/wechat-php-sdk

你的类库文件放在哪里,需要引入文件再试试,import or vendor。

类库是正确的,我在_initialize是可以正确引用的,但是放在其他方法里就不能引用

把初始化方法的protected 改为 public,然后按照三楼写的就对了

在 wechat-php-sdk-master 项目中没有找到 CheckController 类定义
也没找到 _initialize 方法的定义

你能确认 _initialize 在类实例化时就执行了吗?

token 作为身份认证,通常是动态发放的,你写死了可以吗?

_initialize 里可以直接用该类了
token 只是该类的一个参数,不加都可以,但是为什么在tp里面不能用呢

我看到了一个wechat和一个weobj...

<?phpnamespace Index\Controller;use Think\Controller;use Com\Wechat; class WuyeController extends CheckController {      protected $weObj;   protected function _initialize(){         $token = 'weixin'; //微信后台填写的TOKEN         $this->weObj = new Wechat($token);     }     public function index(){         $this->weObj->text("hello, I'm wechat")->reply();         //在这里不能调用上面实例化的类         //如何操作才可以使用     }          public function test(){         $this->weObj->text("hello, I'm wechat")->reply();         //在这里不能调用上面实例化的类         //如何操作才可以使用     } }

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,

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.
