php json schema,json-schema-php
软件简介
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。
生成 JSON Schema
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
}
}
}
使用 JSON Schema 验证 JSON
$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"
}
}
}
}');
