获取价值 Json RajaOngkir [关闭]

Question

我发现很难从 json 的结果中获得价值，如果你有答案，请帮助我...

这是我的代码：

<?php
$asal = '2';
$id_kabupaten = '3';
$kurir = 'jne';
$berat = '1000';

$curl = curl_init();
curl_setopt_array($curl, array(
  CURLOPT_URL => "http://api.rajaongkir.com/starter/cost",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "origin=".$asal."&destination=".$id_kabupaten."&weight=".$berat."&courier=".$kurir."",
  CURLOPT_HTTPHEADER => array(
    "content-type: application/x-www-form-urlencoded",
    "key: ***********"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}?>

Answer 1

您回显结果，而不是您应该json_decode 它，然后您可以访问它的值。

您可能还想重新生成您的 API 密钥。

<?php
$asal = '2';
$id_kabupaten = '3';
$kurir = 'jne';
$berat = '1000';

$curl = curl_init();
curl_setopt_array($curl, array(
  CURLOPT_URL => "http://api.rajaongkir.com/starter/cost",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "origin=".$asal."&destination=".$id_kabupaten."&weight=".$berat."&courier=".$kurir."",
  CURLOPT_HTTPHEADER => array(
    "content-type: application/x-www-form-urlencoded",
    "key: *********************"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
    exit("cURL Error #:" . $err);
}

$response = json_decode($response);

$response 现在将成为一个对象，例如：

/*
stdClass Object
(
    [rajaongkir] => stdClass Object
        (
            [query] => stdClass Object
                (
                    [origin] => 2
                    [destination] => 3
                    [weight] => 1000
                    [courier] => jne
                )

            [status] => stdClass Object
                (
                    [code] => 200
                    [description] => OK
                )

            [origin_details] => stdClass Object
                (
                    [city_id] => 2

                    [province] => Nanggroe Aceh Darussalam (NAD)
                    [type] => Kabupaten
                    [city_name] => Aceh Barat Daya
                    [postal_code] => 23764
                )

            [destination_details] => stdClass Object
                (
                    [city_id] => 3
                    [province_id] => 21
                    [province] => Nanggroe Aceh Darussalam (NAD)
                    [type] => Kabupaten
                    [city_name] => Aceh Besar
                    [postal_code] => 23951
                )

            [results] => Array
                (
                    [0] => stdClass Object
                        (
                            [code] => jne
                            [name] => Jalur Nugraha Ekakurir (JNE)
                            [costs] => Array
                                (
                                    [0] => stdClass Object
                                        (
                                            [service] => CTC
                                            [description] => JNE City Courier
                                            [cost] => Array
                                                (
                                                    [0] => stdClass Object
                                                        (
                                                            [value] => 20000
                                                            [etd] => 2-3
                                                            [note] => 
                                                        )

                                                )

                                        )

                                )

                        )

                )

        )

) 
*/

然后你会像这样访问：

echo $response->rajaongkir->results[0]->costs[0]->cost[0]->value;
