php + curl issue Resource id # 2 on curl
php + curl issue Resource id # 2 on curl_init:
$url = "https://example.com:4433/deviceservice/authorize?login=query"; // URL JSON
$ch = curl_init($url);
echo $ch; //write Resource id # 2
if( $ch )
{
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, TRUE);
$json = curl_exec( $ch );
$json = json_decode($json);
} else {
echo 'nothing';
}
What am I doing wrong?
尝试使用curl_error（$ ch）和echo来诊断错误
$ch= curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
)
);
$response = curl_exec($ch);
$err_status = curl_error($ch);
echo $err_status;
curl_close($ch);
curl_init returns a cURL handle on success, FALSE on errors. So echo $ch; will return something like Resource id #2.
See http://php.net/manual/en/function.curl-init.php
You have to try something like this
$url = "https://example.com:4433/deviceservice/authorize?login=query"; // URL JSON
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, TRUE);
$json = curl_exec( $ch );
$json = json_decode($json);
curl_close($ch);
if(empty($json)){
echo 'nothing';
}
如果您不在具有SSL的主机上，那么您应该绕过SSL验证
<?php
$url = "https://example.com:4433/deviceservice/authorize?login=query";
$ch = curl_init($url);
echo $ch; //write Resource id # 2
if( $ch )
{
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
$json = curl_exec( $ch );
$json = json_decode($json);
} else {
echo 'nothing';
}
