我正在使用版本2.8的Symfony 2项目,我正在使用内置组件Serializer - > http://symfony.com/doc/current/components/serializer.html
我有一个由Web服务提供的JSON结构.反序列化后,我想在对象中反规范化我的内容.这是我的结构(汽车应用程序上下文中的模型/品牌).
[{
"0": {
"id": 0,
"code": 1,
"model": "modelA",
"make": {
"id": 0,
"code": 1,
"name": "makeA"
}
}
} , {
"1": {
"id": 1,
"code": 2,
"model": "modelB",
"make": {
"id": 0,
"code": 1,
"name": "makeA"
}
}
}]
我的想法是填充一个VehicleModel包含对象引用的VehicleMake对象.
class VehicleModel {
public $id;
public $code;
public $model;
public $make; // VehicleMake
}
这是我做的:
// Retrieve data in JSON
$data = ...
$serializer = new Serializer([new ObjectNormalizer(), …我想在我的SF2项目中安装包phpdocumentor/reflexion.所以我运行以下命令,composer require "phpdocumentor/reflection"但我有以下堆栈错误:
Your requirements could not be resolved to an installable set of packages.
Problem 1

public function blockForm($form, FormStateInterface $form_state)
{
$form['key_1'] = [
'#title' => $this->t('Key 1 label'),
'#type' => 'textfield',
'#default_value' => '',
'#required' => false,
];
$form['key_2'] = [
'#title' => $this->t('key 2 link'),
'#type' => 'link',
];
return $form;
}
现在，当我进入 admin/structure/block/manage/myblock 时，我可以看到我的key 1字段。在key 2不渲染。如果我更改任何其他（文本字段、文本区域、文件管理）的类型，我的字段将正确呈现。默认链接模块已启用。
链接字段类型只能在节点形式中使用吗？我能理解为什么。
