此类通过使用基于基本必要数据类型的预定义模式来验证JSON有效负载。可以通过创建新类来扩展数据类型验证，可以通过在Constraints类中编写新函数来添加新的约束。

此模式验证器适用于以下类型

• 文本
• 数值
• 日期
• 数组
• 布尔值
• 选择

约束

• max_length（字符串长度）

• required（对于必填字段）

• value_range min_value max_value（对于数值字段）

• choices [choices array]（对于预定义的选择）

• min_item_count

• max_item_count（对于数组数据类型，限制项目数量）

• sub_nodes（对于嵌套对象）

示例模式

$_payLoadSchema = [
    [
        'node' => [
            'name' => 'title',
            'type' => 'text',
            'required' => true,
            'max_length' => 20
        ]
    ],
    [
        'node' => [
            'name' => 'action',
            'type' => 'text',
            'required' => true,
            'max_length' => 20,
            'choices' => [
                "CUSTOMER_DATA",
                "CUSTOMER_CREATE"
            ]
        ]
    ],
    [
        'node' => [
            'name' => 'transaction_amount',

                'min_value' => 10,
                'max_value' => 100
            ]
        ]
    ],
    [

            'choices' => [
                "2018-01-01",
                "2018-01-02"
            ]
        ]
    ],
    [
        'node' => [
            'name' => 'customer_ids',
            'type' => 'array',
            'required' => true,
            'max_item_count' => 2
        ]
    ],
    [
        'node' => [
            'name' => 'is_active',
            'type' => 'boolean',
            'required' => false
        ]
    ],
    [
        'node' => [
            'name' => 'additional_data',
            'type' => 'object',
            'sub_nodes' => [
                ['node' => [
                        'name' => 'additional_field_1',
                        'type' => 'text',
                        'max_length' => "100"
                    ]],
                ['node' => [
                        'name' => 'additional_field_2',
                        'type' => 'numeric'
                    ]]
            ]
        ]
    ]
];

验证的JSON有效负载示例

$json_raw = '
{
  "title": "This is titlle",
  "action": "CUSTOMER_CREATE",
  "transaction_amount": "44",
  "transaction_date": "2018-01-01",
  "customer_ids": [
    1001,
    1002,
    1003
  ],
  "is_active": true,
  "additional_data": {
    "additional_field_2": 10
  }
}    
';

用法

<?php

	$jsonschemavalidator = new JsonSchemaValidator();
	$jsonschemavalidator->validateSchema($_payLoadSchema, $json_raw);
	
	if($validated){
		echo "JSON Validated";
	} else {
		echo "JSON not validated";
		print_r($jsonschemavalidator->getErrors());
	}
