问题描述
使用curl操作获取数据时遇到问题。在这里我隐藏了令牌,如果我仅在浏览器中使用url,则它将返回数据,但在此处为空。

<?php
$token = "TOKEN"; //the actual token hidden
$url = "https://crm.zoho.com/crm/private/xml/Leads/getRecords?authtoken=".$token."&scope=crmapi";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
$result = curl_exec($ch);
curl_close($ch);
echo $result; //does not return anything
?>

推荐答案
这是尝试使用 CURLOPT_RETURNTRANSFER
(用于返回输出)和 curl_errno()的方法
以跟踪错误:
This is how you can try with CURLOPT_RETURNTRANSFER
which is used to return the output and curl_errno()
to track the errors :
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/my_url.php" );
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$postResult = curl_exec($ch);
if (curl_errno($ch)) {
print curl_error($ch);
}
curl_close($ch);
