Question

我正在构建一个脚本来验证Apple的itunesconnect站点（iphone dev）的交易收据，我无法弄清楚我的代码中的错误在哪里。我希望获得“状态”值。

请帮我找出我做错了什么：

 <?php
    include("config.php");

    $receipt = json_encode(array("receipt-data" => $_GET["receipt"]));
    $response_json = do_post_request($url, $receipt);
    $response = json_decode($response_json);

    //Here's where I try to get the "status" key but doesn't work

    echo $response['status']; 
    //echo $response->status; 

    function do_post_request($url, $data)
    {
       //initialize cURL
     $ch = curl_init();

     // set the target url
     curl_setopt($ch, CURLOPT_URL,$url);

     // howmany parameter to post
     curl_setopt($ch, CURLOPT_POST, 1);

     // the receipt as parameter
     curl_setopt($ch, CURLOPT_POSTFIELDS,$data);

     $result= curl_exec ($ch);
     curl_close ($ch);
     return $result;
    }

    ?>

并且iPhone的答案如下：

{"receipt":{"item_id":"327931059", "original_transaction_id":"1000000000074412", "bvrs":"1.0", "product_id":"sandy_01", "purchase_date":"2009-09-29 16:12:46 Etc/GMT", "quantity":"1", "bid":"com.latin3g.chicasexy1", "original_purchase_date":"2009-09-29 16:12:46 Etc/GMT", "transaction_id":"1000000000074412"}, "status":0}

但只有“状态”：0现在很重要 - 谢谢

Answer 1

来自json_decode()

上的手册

返回一个对象或者是可选的 assoc参数为TRUE，an 而是返回关联数组。如果json不能返回NULL 被解码或编码数据是比递归限制更深。

因此要么为第二个参数发送TRUE

$response = json_decode($response_json, true);

或使用对象语法

访问已解码的JSON

$response->status;

隔离测试

$json = <<<JSON
{"receipt":{"item_id":"327931059", "original_transaction_id":"1000000000074412", "bvrs":"1.0", "product_id":"sandy_01", "purchase_date":"2009-09-29 16:12:46 Etc/GMT", "quantity":"1", "bid":"com.latin3g.chicasexy1", "original_purchase_date":"2009-09-29 16:12:46 Etc/GMT", "transaction_id":"1000000000074412"}, "status":0}
JSON;

$response = json_decode( $json );

echo $response->status;

$response2 = json_decode( $json, true );

echo $response2['status'];

输出

00

你应该可以使用：

$response->status;

将一个true的可选参数传递给json_decode函数会将结果作为关联数组返回。

您是否检查过response_json变量以检查数据是否正确反序列化？即：

var_dump($response);

哪个应该产生：

object(stdClass)#1 (2) {
["receipt"]=>
  object(stdClass)#2 (9) {
    ["item_id"]=>
    string(9) "327931059"
    ["original_transaction_id"]=>
    string(16) "1000000000074412"
    ["bvrs"]=>
    string(3) "1.0"
    ["product_id"]=>
    string(8) "sandy_01"
    ["purchase_date"]=>
    string(27) "2009-09-29 16:12:46 Etc/GMT"
    ["quantity"]=>
    string(1) "1"
    ["bid"]=>
    string(22) "com.latin3g.chicasexy1"
    ["original_purchase_date"]=>
    string(27) "2009-09-29 16:12:46 Etc/GMT"
    ["transaction_id"]=>
    string(16) "1000000000074412"
  }
  ["status"]=>
  int(0)

}
