一个非常简单的方法是使用typo3conf/AdditionalConfiguration.php文件并检查其中的上下文：

<?php
$context = (string)\TYPO3\CMS\Core\Core\Environment::getContext();
if ($context === 'Production/Staging') {
 putenv('SOLR_ENABLED_READ=true');
 putenv('SOLR_HOST=solr');
 putenv('SOLR_PATH=/solr/');
 putenv('SOLR_PORT=8983');
 putenv('SOLR_SCHEME=http');
 putenv('SOLR_CORE_NAME_DE=core_de');
 putenv('SOLR_USER=');
 putenv('SOLR_PWD=');
}

和站点配置中

solr_enabled_read: true
solr_host_read: '%env(SOLR_HOST)%'
solr_password_read: '%env(SOLR_PWD)%'
solr_path_read: '%env(SOLR_PATH)%'
solr_port_read: '%env(SOLR_PORT)%'
solr_scheme_read: '%env(SOLR_SCHEME)%'
solr_use_write_connection: false
solr_username_read: '%env(SOLR_USER)%'
