如何使用PHP Slim框架解析特定類型的JSON？

我有JSON字符串由Android應用發佈到我的基於PHP的苗條框架。如何使用PHP Slim框架解析特定類型的JSON？

這裏是JSON：

ItemList=[{"Address":"addresses 263838","CreatedDate":"2016-11-11 11:53:53","DeviceID":"1","ID":0,"Latitude":24.8715396,"Locality":"locality","Longitude":67.0898003,"Name":"Item ","OfflineId":20161111115352400,"Subchannel":"Subchannel","Sublocality":"Sublocality","ToUpdate":false,"imageLocalPath":"/storage/emulated/0/Pictures/1478847221674.jpg"},{"Address":"address","CreatedDate":"2016-11-11 17:46:41","DeviceID":"1","ID":0,"Latitude":24.87110129,"Locality":"Locality","Longitude":67.09033959,"Name":"Item 23","OfflineId":20161111174637550,"Subchannel":"Subchannel","Sublocality":"Sublocality","ToUpdate":false,"imageLocalPath":"/storage/emulated/0/Pictures/1478868360328.jpg"},{"Address":"Address 648483","CreatedDate":"2016-11-12 09:43:54","DeviceID":"1","ID":0,"Latitude":24.87952002,"Locality":"Locality","Longitude":67.09332882,"Name":"Item 25","OfflineId":20161112094353314,"Subchannel":"Subchannel","Sublocality":"Sublocality","ToUpdate":false,"imageLocalPath":"/storage/emulated/0/Pictures/1478925794392.jpg","imageName":"1478925794392.jpg"}]

苗條框架（PHP）代碼

$app->post('/itemlist', function ($request, $response) { 


$input   = $request->getParsedBody(); 


foreach($input as $item) 
{ 
    $sql = "INSERT INTO jsondump (jsondata) VALUES (:jsondump)"; 

    $resQur = $this->db->prepare($sql); 
    $resQur->bindParam("jsondump", $item);  

    $resQur->execute();  
} 

return $this->response->withJson($input);

}）;

問題/挑戰：對象的JSON列表應該分解爲JSON對象。目前我正在將JSON直接轉儲到數據庫中以查看結果。它總是傾倒整個JSON字符串（包含整個列表）。

使用'json_decode'然後遍歷它。 –

然後如何循環。我在使用foreach時遇到困難。沒有得到預期的結果。 – Abubaker

您應該使用foreach循環訪問它，然後使用特定的鍵來獲取該鍵的數據。請提供您已完成的代碼以及您遇到問題的位置。 –

如果數據發佈時content-type設置爲application/json，則$input將自動解碼。

考慮這個測試路線可調用：

$app->post("/", function ($request, $response, $args) { 
    $input = $request->getParsedBody(); 
    if ($input === null) { 
     echo "FAILED to decode JSON\n"; 
     echo json_last_error_msg(); 
     exit; 
    } 

    var_dump($input); 
});

測試：

 
$ curl -i -H "Content-Type: application/json" \ 
http://localhost:8888 \ 
-d '[{"Address":"addresses 263838","CreatedDate":"2016-11-11 11:53:53","DeviceID":"1","ID":0,"Latitude":24.8715396,"Locality":"locality","Longitude":67.0898003,"Name":"Item ","OfflineId":20161111115352400,"Subchannel":"Subchannel","Sublocality":"Sublocality","ToUpdate":false,"imageLocalPath":"/storage/emulated/0/Pictures/1478847221674.jpg"},{"Address":"address","CreatedDate":"2016-11-11 17:46:41","DeviceID":"1","ID":0,"Latitude":24.87110129,"Locality":"Locality","Longitude":67.09033959,"Name":"Item 23","OfflineId":20161111174637550,"Subchannel":"Subchannel","Sublocality":"Sublocality","ToUpdate":false,"imageLocalPath":"/storage/emulated/0/Pictures/1478868360328.jpg"},{"Address":"Address 648483","CreatedDate":"2016-11-12 09:43:54","DeviceID":"1","ID":0,"Latitude":24.87952002,"Locality":"Locality","Longitude":67.09332882,"Name":"Item 25","OfflineId":20161112094353314,"Subchannel":"Subchannel","Sublocality":"Sublocality","ToUpdate":false,"imageLocalPath":"/storage/emulated/0/Pictures/1478925794392.jpg","imageName":"1478925794392.jpg"}]'

即用在其內三個陣列的陣列。
