理解卷曲电话 - curl_exec返回false
问题描述:
我已经写了下面的代码,并无法得到我所提到以下任何调试信息卷曲响应:理解卷曲电话 - curl_exec返回false
能有人帮,找出为什么这个问题curl_exec返回false。
$jwtToken = getToken();
$service_url = "https://example.com/api/Demo/GetProjectAttributes/1484";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $service_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array (
"Content-Type: application/x-www-form-urlencoded",
"Authorization: Bearer $jwtToken"
));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_CAINFO, getcwd() . "/mycert.crt");
$response = curl_exec($ch);
if ($response === false) {
$info = curl_getinfo($ch);
echo '<pre>';
die('error occured during curl exec. Additioanl info: ' . var_export($info));
curl_close($ch);
}
我的卷发是越来越失败,我得到以下信息:

答
PHP cURL扩展提供了请求时显示错误,如果失败的功能。
尝试使用他们这样的:
$response = curl_exec($ch);
if (!$response || curl_errno($ch) !== CURLE_OK)
{
echo 'cURL error (' . curl_errno($ch) . '): ' . curl_error($ch);
}
,而不是印刷'curl_getinfo'使用'curl_error',它会打印有关的错误的有用信息。 – keune
@keune我用它,它返回空白字符串。 –
