I have a wordpress site that its failing. I tracked the issue and I found that is due to
curl_exec()
failing with HTTPS sites.I’m running php 5.6 in a Alpine Linux v3.8 container with lighttpd.
The logs (error.log) don’t give too much information:
(http-header-glue.c.1250) read(): Connection reset by peer 8 9
(gw_backend.c.2149) response not received, request sent: 1017 on socket: unix:/var/run/lighttpd/php.socket-0 for /curl_test.php?, closing connection
These are the related packages which are installed:
php5-common-5.6.40-r0 php5-cgi-5.6.40-r0 php5-gd-5.6.40-r0 php5-iconv-5.6.40-r0 php5-json-5.6.40-r0 php5-mysqli-5.6.40-r0 php5-zip-5.6.40-r0 php5-xml-5.6.40-r0 php5-dom-5.6.40-r0 php5-intl-5.6.40-r0 php5-ctype-5.6.40-r0 php5-mysql-5.6.40-r0 php5-openssl-5.6.40-r0 php5-curl-5.6.40-r0 curl-7.61.1-r2 libcurl-7.64.1-r1 libssl1.1-1.1.1b-r1 ssl_client-1.30.1-r1 libressl2.7-libcrypto-2.7.5-r0 libressl2.7-libssl-2.7.5-r0 libssl1.0-1.0.2r-r0 lighttpd-1.4.53-r1 lighttpd-openrc-1.4.53-r1 openssl-1.0.2r-r0 ca-certificates-cacert-20190108-r0 ca-certificates-20190108-r0
I have tried to display errors on screen (using error_reporting, etc) but it seems that its crashing before being able to get the error.
I found this similar question, but I believe its not about the code, but more about some library or setting missing in my installation.
The code I’m using for testing is:
error_reporting(E_ALL); ini_set('display_errors', 1); $curl = curl_init( 'https://example.com' ); curl_setopt($curl, CURLOPT_CAINFO, '/etc/lighttpd/cacert.pem'); curl_setopt($curl, CURLOPT_CAPATH, '/etc/ssl/certs'); curl_setopt( $curl, CURLOPT_POST, true ); curl_setopt( $curl, CURLOPT_POSTFIELDS, array( 'field1' => 'some data', 'field2' => 'some more data' ) ); curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true ); $response = curl_exec( $curl ); curl_close( $curl );
Note: I downloaded cacert.pem from here, and
/etc/ssl/certs/
is not empty.The error displayed is: “500 Internal Server Error”.
Not even disabling SSL check works:
curl_setopt($curl, CURLOPT_VERBOSE, true); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
All works if instead of “https” I change it to “http”.
What am I missing?
UPDATE (1)
Following this question I executed:
$w = stream_get_wrappers(); echo 'openssl: ', extension_loaded ('openssl') ? 'yes':'no', "\n"; echo 'http wrapper: ', in_array('http', $w) ? 'yes':'no', "\n"; echo 'https wrapper: ', in_array('https', $w) ? 'yes':'no', "\n"; echo 'wrappers: ', var_export($w);
The result is:
openssl: yes http wrapper: yes https wrapper: yes wrappers: array ( 0 => 'compress.zlib', 1 => 'php', 2 => 'file', 3 => 'glob', 4 => 'data', 5 => 'http', 6 => 'ftp', 7 => 'https', 8 => 'ftps', 9 => 'zip', )
Note:
allow_url_fopen
is on.UPDATE (2)
I moved the site into a fresh container and it works fine. Some library or something was causing this issue.
Answer
I faced this issue in another container and updating to php7 solved the issue.
