如何使用 PHP Slim 框架解析特定类型的 JSON？

Question

我有 JSON 字符串被 Android 应用程序发布到我基于 PHP 的 slim 框架。

这里是 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"}]

Slim 框架（PHP）代码

$app->post('/itemlist', function ($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);

});

Problem/Challenge: JSON 对象列表应分为 JSON 个对象。目前我正在将 JSON 直接转储到数据库中以查看结果。它总是转储整个 JSON 字符串（包含整个列表）。

如果在发布数据时将content-type设置为application/json，则$input将自动解码。

考虑此测试路由可调用：

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

    var_dump($input);
});

测试：

$ 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"}]'

即一个包含三个数组的数组。
