JSON Schema 用于描述JSON数据的结构和类型。如同DTD与XML的关系。
本实现用于使用 PHP 调用 JSON Schema 对 JSON 数据进行验证。
由JSON生成一个全格式的Schema,方便编辑修改(勿随便直接使用在实践中)。
$value = new stdClass(); $value->name = 'a name'; $value->age = 23; $value->height = 183.5; $jsonSchema = new JsonSchema(json_encode($value)); echo $jsonSchema->getSchema();
结果(真实结果格式化后)
{ "type":"object", "properties":{ "name":{ "type":"string", "format":"regex", "pattern":"\/^[a-z0-9]+$\/i", "minLength":0, "maxLength":2147483647 }, "age":{ "type":"integer", "default":0, "minimum":0, "maximum":2147483647, "exclusiveMinimum":0, "exclusiveMaximum":2147483647 }, "height":{ "type":"number", "default":0, "minimum":0, "maximum":2147483647, "exclusiveMinimum":0, "exclusiveMaximum":2147483647 } } }
$userType = ' { "id": "user", "description": "user info", "type": "object", "properties": { "account": {"type": "string"}, "email": {"type": "string", "required": true}, "noexist": {"type": "string", "required": false} } }'; $type = array(); $type['users'][] = array('account' => 'userA', 'email' => 'userA@example.com'); $type['users'][] = array('account' => 'userB', 'email' => 'userB@example.com'); $type['users'][] = array('account' => 'userC', 'email' => 'userC@example.com'); $jsonSchema = new JsonSchema(json_encode($type)); $jsonSchema->addTypes($userType); $jsonSchema->validate(' { "type":"object", "properties":{ "users":{ "type":"array", "items":{ "$ref":"user" } } } }');
