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 }}
回复讨论(解决方案)
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 } }

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.
