Json Schema Silex 服务提供者和验证工具

一个用于验证 JSON 数据与给定 Schema 的 Silex 服务提供者。

安装

库

$ git clone https://github.com/onlinesid/json-schema-provider.git

依赖

Composer (将使用 Composer 类加载器)

$ wget https://composer.php.ac.cn/composer.phar
$ php composer.phar require onlinesid/json-schema-provider:dev-master

使用

注册服务提供者

$app->register(new OnlineSid\Silex\Provider\JsonSchema\ServiceProvider(), array(
    'json-schema.options' => array(
        'json_schema_dir' => __DIR__.'/public/json-schema/',
        'json_message_dir' => __DIR__.'/public/json-message/',
        'default_json_message' => 'default.json',
    ),
));

• json_schema_dir: 存储json schema文件的目录
• json_message_dir: 存储自定义错误信息的json文件的目录
• default_json_message: 存储默认错误信息的json文件，文件必须位于json_message_dir目录下

在控制器中使用

$validator = $this->app['json-schema-validator'];
$validation_result = $validator->validate(array(
    'request' => $this->request->get('booking'), // array to validate
    'json_schema' => 'booking.json', // under json_schema_dir
    'json_message' => 'booking.json', // under json_message_dir
));

// check $validation_result->isValid() to see if validation pass or fail

####json-schema/booking.json 请参阅json-schema获取更多详情。

这是包含约束/规则的json schema

{
  "type": "object",
  "properties": {
    "first_name": {
      "type": "string",
      "required": true,
      "maxLength": 100
    },
    "last_name": {
      "type": "string",
      "required": true,
      "maxLength": 100
    }
  }
}

####json-message/booking.json 您可以指定自己的自定义错误信息。

{
  "first_name": {
    "label": "First name",
    "messages": {
      "required": "{{ label }} is required.",
      "maxLength": "{{ label }} must not be more than {{ schema.maxLength }} characters long."
    }
  },
  "last_name": {
    "label": "Last name",
    "messages": {
      "required": "{{ label }} is required.",
      "maxLength": "{{ label }} must not be more than {{ schema.maxLength }} characters long."
    }
  }
}

####json-message/default.json 您可以指定全局默认错误信息（例如：不是按字段而是按约束规则类型）

{
  "messages": {
    "required": "Required field.",
    "minLength": "Must be {{ schema.minLength }} chars or more.",
    "maxLength": "Must not be more than {{ schema.maxLength }} chars.",
    "pattern": "Incorrect format"
  }
}
