我有以下捆绑包配置:
$supportedAdapters = array('curl', 'socket');
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root('example_bundle');
$rootNode
->children()
->scalarNode('username')->isRequired()->cannotBeEmpty()->end()
->scalarNode('password')->isRequired()->cannotBeEmpty()->end()
->scalarNode('adapter')
->validate()
->ifNotInArray($supportedAdapters)
->thenInvalid('The adapter %s is not supported. Please choose one of '.json_encode($supportedAdapters))
->end()
->cannotBeOverwritten()
->isRequired()
->cannotBeEmpty()
->end()
// allow the use of a proxy for cURL requests
->arrayNode('proxy')
->children()
->scalarNode('host')->isRequired()->cannotBeEmpty()->end()
->scalarNode('port')->isRequired()->cannotBeEmpty()->end()
->scalarNode('username')->defaultValue(null)->end()
->scalarNode('password')->defaultValue(null)->end()
->end()
->end();
return $treeBuilder;
我们支持两种适配器:curl
和socket
.
curl
我们仅支持对请求使用代理。在配置中,我想检查是否设置了代理并且适配器不是 curl,然后抛出错误通知用户“我们只支持 curl 适配器与代理一起使用”。有没有办法获得一个设定值(在我们的例子中是适配器)并检查它的值并对其进行验证?
伪代码:
IF PROXY IS SET AND ADAPTER IS NOT EQUAL TO CURL THEN:
THROW ERROR ("We don't support the use of a proxy with the socket adapter");
END IF;
我希望这是有道理的。我已经阅读了所有文档和 API 文档,但是,唉,我看不到实现这一点的选项。
