我想在cloudControl(像heroku这样的PaaS提供程序)容器上使用Symfony2和MongoDB。现在Symfony2 supports the usage of MongoDB:
# app/config/config.yml
doctrine_mongodb:
connections:
default:
server: mongodb://localhost:27017
options: {}
default_database: test_database
document_managers:
default:
auto_mapping: true
由于MongoDB是一个PaaS AddOn,我没有静态连接凭据。它们由容器生成。 cloudControl提供了这种方式来访问PHP中的凭据:
$credfile = file_get_contents($_ENV['CRED_FILE'], false);
$credentials = json_decode($credfile, true);
$uri = $credentials["MONGOLAB"]["MONGOLAB_URI"];
$m = new Mongo($uri);
$db = $m->selectDB(myDbName);
$col = new MongoCollection($db, myCollection);
如何将这些动态获取的凭据导入Symfony2 config.yml
?

解决方案是使用Symfony2 Miscellaneous Configuration。
因此,请创建包含以下内容的app/config/credentials.php
文件:
<?php
if (isset($_ENV['CRED_FILE'])) {
// read the credentials file
$string = file_get_contents($_ENV['CRED_FILE'], false);
if ($string == false) {
throw new Exception('Could not read credentials file');
}
// the file contains a JSON string, decode it and return an associative array
$creds = json_decode($string, true);
// overwrite config server param with mongolab uri
$uri = $creds["MONGOLAB"]["MONGOLAB_URI"];
$container->setParameter('doctrine_mongodb.connections.default.server', $uri);
}
然后在app/config/config.yml
添加:
imports:
- { resource: credentials.php }
如果这可以解决您的问题,请告诉我。
