There is a third-party package for WeChat. After installing it through composer, I want to instantiate the WeChat class directly through Yii::$app->wechat
, so I configured the following web.php
in the components
array in
<code> 'wechat' => [ 'class' => 'EasyWeChat\Foundation\Application', ], </code>
The following error will be reportedMissing required parameter "config" when instantiating "EasyWeChatFoundationApplication".
I saw that the instantiation of this class requires an array to be passed in as a configuration file, so I changed the code to the following:
<code> 'wechat' => [ 'class' => 'EasyWeChat\Foundation\Application', 'config' => [ 'debug' => true, 'app_id' => 'your-app-id', 'secret' => 'you-secret', 'token' => 'easywechat', 'log' => [ 'level' => 'debug', 'file' => '/tmp/easywechat.log', // XXX: 绝对路径!!!! ], //... ], ], </code>
But still the same, Missing required parameter "config" when instantiating "EasyWeChatFoundationApplication".
So I want to ask, if I want to instantiate something like this that requires parameters, how do I pass in the parameters?

in bootstrap.php
<code> Yii::$container->set(EasyWeChat\Foundation\Application::class, [], [ [ 'debug' => true, 'app_id' => 'your-app-id', 'secret' => 'you-secret', 'token' => 'easywechat', 'log' => [ 'level' => 'debug', 'file' => '/tmp/easywechat.log', // XXX: 绝对路径!!!! ], //... ], ]);</code>
In the configuration file, configuring the parameters of construct
is not supported. You need to configure container
to tell Yii to inject the configuration information into contruct
during instantiation.
Give you a DEMO
<code> public function actionWechat() { $options = [ 'debug' => false, 'app_id' => 'wx3f3ea1dd10a123445', 'secret' => '63005e31fd123123123123', 'token' => '123123123123123', 'log' => [ 'level' => 'debug', 'file' => '/tmp/easywechat.log', ], 'verify' // ... ]; $openid = '123123123123123'; $message = 'hello wechat'; $app = new \EasyWeChat\Foundation\Application($options); $result = $app->staff->message($message)->to($openid)->send(); var_dump($result); die; }</code>
You write like this
Try it Yii::$app->params['wechat'];
