我正在开发一个PHPYII2应用程序。我对yii2有一个奇怪的问题,这是我的问题

正如我们所知,Yii2项目中有一个web\assets文件夹,它将加载自己的资产包,但在配置负载平衡时,我发现chrome的开发者工具控制台抛出以下错误:

使用负载平衡ip访问时找不到js、css文件,但一旦我使用服务器的ip,正好有一个Yi2应用程序在运行,网页就会成功加载js、css文件:

有两台服务器完全运行Yii2,它们都有自己的web\assets文件夹,并且具有不同的缓存:

我发现一旦我停止了一台Yii2服务器,负载平衡服务器就会成功工作。因此,我猜问题可能是由Yii2的web\assets文件夹造成的。从上面的两张图片中,我们可以发现Yii2使用md5重命名其中的文件夹,因此,可能是因为两台Yii2服务器的web\assets文件夹具有不同的命名子文件夹,导致了问题的发生

但是,我已尝试使用以下代码解决此问题:

<?php

$params = require(__DIR__ . '/params.php');

$config = [
'id' => 'basic',
'defaultRoute'=>'firekylin',
'basePath' => dirname(__DIR__),
'bootstrap' => ['log'],
'components' => [

    'view' => [
        'theme' => [
            'pathMap' => [
                '@app/views' => '@app/views/dmstr/yii2-adminlte-asset/example-views/yiisoft/yii2-app'
            ],
        ],
    ],

    'assetManager' => [

        // send all mails to a file by default. You have to set
        // 'useFileTransport' to false and configure a transport
        // for the mailer to send real emails.
        'useFileTransport' => true,
    ],
    'log' => [
        'traceLevel' => YII_DEBUG ? 3 : 0,
        'targets' => [

            ],
        ],
    ],
    'db' => require(__DIR__ . '/db.php'),
    /*
    'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'rules' => [
        ],
    ],
    */
],
'params' => $params,
];

if (YII_ENV_DEV) {
$config['bootstrap'][] = 'debug';
$config['modules']['debug'] = [
    'class' => 'yii\debug\Module',
];

$config['bootstrap'][] = 'gii';
$config['modules']['gii'] = [
    'class' => 'yii\gii\Module',
];
$config['components']['assetManager']['forceCopy'] = true;
}

return $config;
我尝试使用assetManager或

$config['components']['assetManager']['forceCopy'] = true;

在config\web.php或function beforeAction中,在我自己的控制器中禁用assets文件夹,但它不起作用。是否有任何方法可以解决此问题?

确保两台服务器上的Yi2 core的文件路径和版本相同

扩展
assetManager
类和自定义
hash()
函数每次更改资产时,请记住清除资产文件夹。

例如:

另一种方式:

  • 使用hashCallback属性:$hashCallback详细信息
  • 将负载平衡配置更改为基于会话的路由,例如:NGINX 会话持久性
  • 将CDN用于资产

  • 确保两台服务器上的yii2 core的文件路径和版本相同。然后清除资产文件夹。两个文件的路径都是var/www/prj4_firekylin/firekylin_php,我已经清除了文件夹,但它不起作用:(它们的子文件的名称仍然不同。对不起,我的错误。这还取决于文件的创建时间。
    $config['components']['assetManager']['forceCopy'] = true;
    
    Class MyAssetManager extend yii\web\AssetManager{
        protected function hash($path)
        {
            $path = is_file($path) ? dirname($path) : $path;
            return sprintf('%x', crc32($path . Yii::getVersion()));
        }
    }
