json_de code未回，卷曲呼叫API响应的正确PHP数组 [英] json_decode is not returning proper php array of api response with curl call

问题描述

我的工作对航运API为我的客户之一。我从供应商船运API。在作出JSON格式卷曲请求，JSON响应不转化为PHP数组？在下面找到code：

I am working on the shipping API for one of my client. I have the shipping api from the vendor. On making curl request in json format, the json response is not converted into php array? Find the code below:

$params['format'] = 'json';
$params['data'] =json_encode($package_data);
$token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$url = "http://test.shipping.co/push/json/?token=".$token;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($params));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
$result = curl_exec($ch);
curl_close($ch);
print_r($result);
$results = json_decode($result, true);
print_r($results);

在这里，我有2个print_r的功能，下面是输出：

Here I have 2 print_r function, and following is the output:

{cash_pickups_count：1.0，cod_count：0，成功：真实，
  package_count：1，upload_wbn：UPL21969440，replacement_count：
  0，cod_amount：0.0，prepaid_count：0，pickups_count：0，
  套餐：[{地位：成功，运单：0008110000125
  引用句柄：8，客户：演示，备注：，cod_amount：
  21841.0，支付：现金}]，cash_pickups：21841.0} 1

{ "cash_pickups_count": 1.0, "cod_count": 0, "success": true, "package_count": 1, "upload_wbn": "UPL21969440", "replacement_count": 0, "cod_amount": 0.0, "prepaid_count": 0, "pickups_count": 0, "packages": [ { "status": "Success", "waybill": "0008110000125", "refnum": "8", "client": "demo", "remarks": "", "cod_amount": 21841.0, "payment": "Cash" } ], "cash_pickups": 21841.0 }1

我收到2输出：1

我要访问数组中的这种反应PHP。我试图json_de code（），但它没有正确响应。
这里需要你的投入。先谢谢了。

I want to access the array in php of this response. I tried json_decode() but it is not responding properly. Need your inputs here. Thanks in advance.

推荐答案

的问题是，你没有设置 CURLOPT_RETURNTRANSFER 选项。在这种情况下卷曲直接输出响应到 STDOUT （浏览器）和 curl_exec 收益真实。正因为如此 json_de code 不能去code $结果变量（因为它的价值= 真正）。

The problem is that you haven't set CURLOPT_RETURNTRANSFER option. In this case CURL outputs response directly into STDOUT (browser) and curl_exec returns true. Because of this json_decode cannot decode $result variable (since it has value = true).

所以，你必须设置 CURLOPT_RETURNTRANSFER 选项：

So you have to set CURLOPT_RETURNTRANSFER option:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($params));
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
$result = curl_exec($ch);
curl_close($ch);
print_r($result);
$results = json_decode($result, true);
print_r($results);
