Yii2 $ How to customize components in the app

There is a third-party package. after composer is installed, I want to instantiate this class directly through Yii: $ app-& amp; gt; wechat, so I am on the web. the following {code...} is configured in the components array of php ...} the following error is reported: Missingrequiredparameter & quot; config & quot ;... there is a third-party package. after being installed through composer, I want to directly use \Yii::$app->wechatTo instantiate this class, so I am web.phpIn componentsThe array is configured as follows:

    'wechat' => [                'class' => 'EasyWeChat\Foundation\Application',            ],

The following error is reported:Missing required parameter "config" when instantiating "EasyWeChat\Foundation\Application".
After reading this class instantiation, you need to input an array as the configuration file, so I changed the code to the following:

'Cmd' => ['class' => 'easywechat \ Foundation \ application', 'config' => ['debug' => true, 'app _ id' => 'Your-app-id', 'secret' => 'You-secret', 'token' => 'easychat ', 'log' => ['level' => 'debug', 'file' => '/tmp/easywechat. log', // XXX: absolute path !!!! ], //...],],

But it is still the same,Missing required parameter "config" when instantiating "EasyWeChat\Foundation\Application".

So I would like to ask how to input the parameter to be instantiated in this way?

Inbootstrap.phpMedium

Yii: $ container-> set (EasyWeChat \ Foundation \ Application: class, [], [['debug' => true, 'app _ id' => 'Your-app-id', 'secret' => 'You-secret', 'token' => 'easychat ', 'log' => ['level' => 'debug', 'file' => '/tmp/easywechat. log', // XXX: absolute path !!!! ], //...],]);

Configuration is not supported in the configuration fileconstruct. You need to configurecontainerTo tell Yii to inject configuration information during instantiation.contructMedium

Here is a DEMO.

 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;    }

You writeYii::$app->params['wechat'];Try it
