What to do if php curl output is incomplete

php curl output incomplete solution: 1. Open the corresponding PHP code file; 2. Add the configuration as "curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));"; 3. The encapsulation method is "function req_curl($url, &$status = null, $options = array()){...}".

The operating environment of this tutorial: Windows 7 system, PHP version 8.1, Dell G3 computer.

php curl output is incomplete? PHP gets data but curl gets incomplete?

Because the PHP CURL library has a default length of 1024 bytes and does not wait for data to be returned, so your code needs to add a configuration:

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));

Give you a more comprehensive encapsulation method:

function req_curl($url, &$status = null, $options = array())
{
$res = '';
$options = array_merge(array(
'follow_local' => true,
'timeout' => 30,
'max_redirects' => 4,
'binary_transfer' => false,
'include_header' => false,
'no_body' => false,
'cookie_location' => dirname(__FILE__) . '/cookie',
'useragent' => 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1',
'post' => array() ,
'referer' => null,
'ssl_verifypeer' => 0,
'ssl_verifyhost' => 0,
'headers' => array(
'Expect:'
) ,
'auth_name' => '',
'auth_pass' => '',
'session' => false
) , $options);
$options['url'] = $url;
$s = curl_init();
if (!$s) return false;
curl_setopt($s, CURLOPT_URL, $options['url']);
curl_setopt($s, CURLOPT_HTTPHEADER, $options['headers']);
curl_setopt($s, CURLOPT_SSL_VERIFYPEER, $options['ssl_verifypeer']);
curl_setopt($s, CURLOPT_SSL_VERIFYHOST, $options['ssl_verifyhost']);
curl_setopt($s, CURLOPT_TIMEOUT, $options['timeout']);
curl_setopt($s, CURLOPT_MAXREDIRS, $options['max_redirects']);
curl_setopt($s, CURLOPT_RETURNTRANSFER, true);
curl_setopt($s, CURLOPT_FOLLOWLOCATION, $options['follow_local']);
curl_setopt($s, CURLOPT_COOKIEJAR, $options['cookie_location']);
curl_setopt($s, CURLOPT_COOKIEFILE, $options['cookie_location']);
if (!empty($options['auth_name']) && is_string($options['auth_name']))
{
curl_setopt($s, CURLOPT_USERPWD, $options['auth_name'] . ':' . $options['auth_pass']);
}
if (!empty($options['post']))
{
curl_setopt($s, CURLOPT_POST, true);
curl_setopt($s, CURLOPT_POSTFIELDS, $options['post']);
//curl_setopt($s, CURLOPT_POSTFIELDS, array('username' => 'aeon', 'password' => '111111'));
}
if ($options['include_header'])
{
curl_setopt($s, CURLOPT_HEADER, true);
}
if ($options['no_body'])
{
curl_setopt($s, CURLOPT_NOBODY, true);
}
if ($options['session'])
{
curl_setopt($s, CURLOPT_COOKIESESSION, true);
curl_setopt($s, CURLOPT_COOKIE, $options['session']);
}
curl_setopt($s, CURLOPT_USERAGENT, $options['useragent']);
curl_setopt($s, CURLOPT_REFERER, $options['referer']);
$res = curl_exec($s);
$status = curl_getinfo($s, CURLINFO_HTTP_CODE);
curl_close($s);
return $res;
}
