使用 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）; 卷曲并通过 json_decode（） ...传递 true 。

Use curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); in your curl and pass true with json_decode()....

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "affiliate-feeds.snapdeal.com/feed/api/order?startDate=2016-01-01&endDate=2016-05-03&status=approved");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt(
            $ch, CURLOPT_HTTPHEADER,
            array(
                    'Snapdeal-Affiliate-Id:'.$affiliateId,
                    'Snapdeal-Token-Id:'.$token,
                    'Accept:application/json'
            )
    );
    $response = curl_exec($ch);
    curl_close($ch);

    // work with $response here:
    $jsonData = json_decode($response,true);
     Mage::log($jsonData['productDetails'][0]['product']); 

这将输出：
