Yii2 params 在公共目录中的本地配置文件中访问 [英] Yii2 params access within local config file in common directory

问题描述

我正在使用 Yii2 高级模板，我想访问 main-local.php 文件中的 params.php，我这样称呼:

ma​​in-local.php:

'mailer' =>['类' =>'我的课'，'apikey' =>\Yii::$app->params['mandrill_api_key'],'视图路径' =>'@common/mail',],

并且我已经将这个 mandrill_api_key 存储在 params.php

params.php:

'[e-mail]','supportEmail' =>'[e-mail]','user.passwordResetTokenExpire' =>3600,'mandrill_api_key' =>'我的钥匙'];

我收到此错误:

<块引用>

注意:第 25 行试图在 C:\xampp\htdocs\myproject\common\config\main-local.php 中获取非对象的属性

我应该怎么做才能访问这些参数?

解决方案

在应用程序实例化之前读取配置文件，如 请求生命周期:

<块引用>

1. 用户向入口脚本 web/index.php 发出请求.
2. 入口脚本加载应用程序配置并创建一个应用程序实例来处理请求.
3. 应用程序在请求应用程序组件的帮助下解析请求的路由.
4. ...

因此 \Yii::$app 尚不存在，因此出现错误.我建议将您的 api_key 定义移动到 main-local.php 配置，这样就不会混淆它的设置位置:

'mailer' =>['类' =>'我的课'，'apikey' =>'实际的 api 密钥','视图路径' =>'@common/mail',],

或者，您可以使用 Yii2 的 依赖注入容器 在应用程序的入口脚本中设置 apikey:

<代码>...$app = new yii\web\Application($config);\Yii::$container->set('\fully\qualified\myClass', ['apikey' =>\Yii::$app->params['mandrill_api_key'],]);$app->run();

I'm using Yii2 advanced template, I want to access params.php in main-local.php file, I called this ways:

main-local.php:

'mailer' => [
            'class' => 'myClass',
             'apikey' => \Yii::$app->params['mandrill_api_key'],
             'viewPath' => '@common/mail',            
        ],

and I have stored this mandrill_api_key in params.php

params.php:

<?php
return [
    'adminEmail' => '[e-mail]',
    'supportEmail' => '[e-mail]',
    'user.passwordResetTokenExpire' => 3600,
     'mandrill_api_key' => 'mykey'
];

I'm getting this error:

Notice: Trying to get property of non-object in C:\xampp\htdocs\myproject\common\config\main-local.php on line 25

What should I do to access these parameters?

解决方案

The config files are read before the application is instantiated as explained in the request lifecycle:

1. A user makes a request to the entry script web/index.php.
2. The entry script loads the application configuration and creates an application instance to handle the request.
3. The application resolves the requested route with the help of the request application component.
4. ...

As such \Yii::$app does not yet exist hence the error. I would suggest moving your api_key definition to the main-local.php config such that there is no confusion over where it is being set:

'mailer' => [
    'class' => 'myClass',
    'apikey' => 'actual api key',
    'viewPath' => '@common/mail',            
],

Alternatively, you can use Yii2's dependancy injection container to set the apikey in your application's entry script:

...
$app = new yii\web\Application($config);
\Yii::$container->set('\fully\qualified\myClass', [
    'apikey' => \Yii::$app->params['mandrill_api_key'],
]);
$app->run();
