Question

其中一个API返回响应作为对象数组，我json编码对象数组如下

{"errors":[{"category":"INVALID_REQUEST_ERROR","code":"MISSING_REQUIRED_PARAMETER","detail":"Missing required parameter.","field":"amount_money.amount"}]}

我想获取详细信息字段值，如何获取它。

Answer 1

使用点符号访问对象元素：

＆＃13;

     // if that response is as string JSON
    var obj = JSON.parse('{"errors":[{"category":"INVALID_REQUEST_ERROR","code":"MISSING_REQUIRED_PARAMETER","detail":"Missing required parameter.","field":"amount_money.amount"}]}');

    alert("Details is: "+obj.errors[0].detail);

＆＃13;

Answer 2

您可以立即阅读响应数组中的detail字段。

<?php
$json = '{"errors":[{"category":"INVALID_REQUEST_ERROR","code":"MISSING_REQUIRED_PARAMETER","detail":"Missing required parameter.","field":"amount_money.amount"}]}';

我只是将您的JSON转换为Array。

//Actual Array Response
$a = json_decode($json, true);

echo "<pre>";
print_r($a);
echo "</pre>";

//Save detail to Variable
$detail = $a['errors'][0]['detail'];
echo $detail;
?>

Answer 3

您的数组结构是：

array (size=1)
  'errors' => 
    array (size=1)
      0 => 
        array (size=4)
          'category' => string 'INVALID_REQUEST_ERROR' (length=21)
          'code' => string 'MISSING_REQUIRED_PARAMETER' (length=26)
          'detail' => string 'Missing required parameter.' (length=27)
          'field' => string 'amount_money.amount' (length=19)

所以要想到底，你可以这样：

$array = json_decode('{"errors":[{"category":"INVALID_REQUEST_ERROR","code":"MISSING_REQUIRED_PARAMETER","detail":"Missing required parameter.","field":"amount_money.amount"}]}',true);    
echo $array['errors'][0]['detail'];

Answer 4

（伪）

$response = Array (
    [errors] => Array (
        [0] => stdClass Object (
            [category] => INVALID_REQUEST_ERROR
            [code] => MISSING_REQUIRED_PARAMETER
            [detail] => Missing required parameter.
            [field] => amount_money.amount
        )
    )
)

要直接访问（以及不编码为JSON）详细信息，您只需使用（类似）以下内容：

$response['errors'][0]->detail

显然，$response持有相关数组。你的剧本可能有所不同。

然后您将该值分配给变量$detail = $response['errors'][0]->detail;，或者只需输出echo $response['errors'][0]->detail;无论您喜欢什么。
