将Azure表存储实体转换为JSON

有没有办法将Azure表存储实体转换为JSON？将Azure表存储实体转换为JSON

PHP中的Azure实体对象有很多元数据。有没有一种很好的方法来清除它，并返回一个只包含相关数据的JSON对象。

实体对象打印这样的事情

WindowsAzure\Table\Models\Entity Object 
     (
      [_etag:WindowsAzure\Table\Models\Entity:private] => W/"datetime'2013-10-07T04%3A19%3A37.0155205Z'" 
      [_properties:WindowsAzure\Table\Models\Entity:private] => Array 
       (
        [PartitionKey] => WindowsAzure\Table\Models\Property Object 
         (
          [_edmType:WindowsAzure\Table\Models\Property:private] => 
          [_value:WindowsAzure\Table\Models\Property:private] => weather 
         ) 

        [RowKey] => WindowsAzure\Table\Models\Property Object 
         (
          [_edmType:WindowsAzure\Table\Models\Property:private] => 
          [_value:WindowsAzure\Table\Models\Property:private] => 0d625293-ef40-492b-bf07-d2889597a8f4 
         ) 

        [Timestamp] => WindowsAzure\Table\Models\Property Object 
         (
          [_edmType:WindowsAzure\Table\Models\Property:private] => Edm.DateTime 
          [_value:WindowsAzure\Table\Models\Property:private] => DateTime Object 
           (
            [date] => 2013-10-07 04:19:37 
            [timezone_type] => 3 
            [timezone] => UTC 
           ) 

         ) 

        [type] => WindowsAzure\Table\Models\Property Object 
         (
          [_edmType:WindowsAzure\Table\Models\Property:private] => Edm.Int32 
          [_value:WindowsAzure\Table\Models\Property:private] => 1 
         ) 

        [city] => WindowsAzure\Table\Models\Property Object 
         (
          [_edmType:WindowsAzure\Table\Models\Property:private] => 
          [_value:WindowsAzure\Table\Models\Property:private] => Pune 
         ) 


        [temperature] => WindowsAzure\Table\Models\Property Object 
         (
          [_edmType:WindowsAzure\Table\Models\Property:private] => Edm.Int32 
          [_value:WindowsAzure\Table\Models\Property:private] => 34.7 
         ) 

        [localTime] => WindowsAzure\Table\Models\Property Object 
         (
          [_edmType:WindowsAzure\Table\Models\Property:private] => 
          [_value:WindowsAzure\Table\Models\Property:private] => 2013-10-07T04:19:31.724Z 
         ) 

       ) 

     )

我想有一个干净的JSON输出这样的事情

{ 
    PartitionKey:"weather", 
    RowKey: "0d625293-ef40-492b-bf07-d2889597a8f4", 
    Timestamp: "2013-10-07 04:19:37" 
    type: 1, 
    city: "Pune", 
    tempterature: 34.7 
    localTime: "2013-10-07T04:19:31.724Z" 
}

我实现了一个循环来实现这一目标。我不确定这是否是最好的方法。

$entities = $result->getEntities(); 
     $jsonArray = array(); 

     for ($i = 0; $i < count($entities); $i++) { 
      $arr = $entities[$i]->getProperties(); 
      $tempArr = array(); 
      foreach ($arr as $key => $value) { 
       if(gettype($entities[$i]->getPropertyValue($key)) != 'object'){ 

        $tempArr[$key] = (string)$entities[$i]->getPropertyValue($key);     } 
       else 
       { 

        $tempArr[$key] = serialize($entities[$i]->getPropertyValue($key)); 
       } 
      } 
      array_push($jsonArray, $tempArr); 
     } 
     echo json_encode($jsonArray);

不确定你的意思是“PHP中的Azure实体对象有很多元数据”。你可以解释吗？此外，由于Azure表存储是无模式设计，因此不存在空属性。 –

更新了问题。 –

他意味着Azure实体对象有很多信息超出预期的数据。而且这个对象没有很好的文档记载，这样一个局外人无法提出合理的理解，而没有提出让他对那些知情者有些愚蠢的问题 –
