PHP中的JSON Patch (http://tools.ietf.org/html/rfc6902) 实现

安装

将 victuxbb/jsonpatch 添加到你的 composer.json 文件中

{
    "require": {
        "victuxbb/jsonpatch": "@stable"
    }
}

或在你的项目根目录内

$ composer require victuxbb/jsonpatch @stable

文档

以这样的目标JSON为例

$targetJSON ='{"baz": "qux","foo": "bar"}';

和一个包含JSON字符串的变量进行操作

$patchOperations = '[
     { "op": "replace", "path": "/baz", "value": "boo" }
   ]';

创建一个Patcher实例，使用"patch"方法获取json结果

$patcher = new Patcher();
$result = $patcher->patch($targetJSON,$patchOperations);

$result将包含

{"baz":"boo","foo":"bar"}

与FOSRestBundle和JMSSerializer的典型用例

public function patchUserAction(Request $request,User $user)
    {            
        $json = $request->getContent();
        $jps = $this->get('json_patch_service'); //symfony service that loads Patcher.php
        $serializer = $this->get("jms_serializer");

        $serializerGroup = array('view');

        $sc = SerializationContext::create();
        $sc->setGroups($serializerGroup);

        $jsonUser = $serializer->serialize($user,'json',$sc); //Generating the json target of object that we want to update
        $jsonUser = $jps->patch($jsonUser,$json); //json result with the changes applied of the json operations

        $dc = DeserializationContext::create();
        $dc->setAttribute('target',$user);

        //Restore the doctrine entity object with deserialization and targeting the object with DeserializationContext
        $serializer->deserialize($jsonUser,'Groupalia\BizApiBundle\Entity\User','json',$dc);
        
        $em = $this->getDoctrine()->getManager();
        $em->persist($user);
        $em->flush();

        $response = new Response();
        $response->setStatusCode(200);
        
        return $response;

    }
