ucenter home does not support fsockopen but supports communication problems between ucenter and modoer in culr environment
So I suspected whether it was an encoding problem, a file permission problem, or a function not supported. After investigation, I found that Wanwang’s L1 host did not support fsockopen, and there was a problem in uc_fopen in the file uc_client/client.php. Here The code is like this:
Copy code The code is as follows:
function uc_fopen($url, $limit = 0, $post = '', $cookie = '', $bysocket = FALSE, $ip = '', $timeout = 15, $block = TRUE) {
$return = '';
$matches = parse_url($url);
!isset($matches['host']) && $matches['host' ] = '';
!isset($matches['path']) && $matches['path'] = '';
!isset($matches['query']) && $matches['query'] = '';
!isset($matches['port']) && $matches['port'] = '';
$host = $matches['host'];
$path = $matches['path'] ? $matches['path'].($matches['query'] ? '?'.$matches['query'] : '') : '/';
$port = !empty($matches['port ']) ? $matches['port'] : 80;
if($post) {
$out = "POST $path HTTP/1.0rn";
$out .= "Accept: */*rn";
//$out .= "Referer: $boardurlrn";
$out .= "Accept-Language: zh-cnrn";
$out .= "Content-Type: application/x-www-form-urlencodedrn";
$out .= "User-Agent: $_SERVER[HTTP_USER_AGENT]rn";
$out .= "Host: $hostrn";
$out .= 'Content-Length: '.strlen($post)."rn" ;
$out .= "Connection: Closern";
$out .= "Cache-Control: no-cachern";
$out .= "Cookie: $cookiernrn";
$out .= $post;
} else {
$out = "GET $path HTTP/1.0rn";
$out .= "Accept: */*rn";
//$out .= "Referer: $boardurlrn";
$out .= "Accept -Language: zh-cnrn";
$out .= "User-Agent: $_SERVER[HTTP_USER_AGENT]rn";
$out .= "Host: $hostrn";
$out .= "Connection: Closern";
$out .= "Cookie: $cookiernrn";
}
$fp = @fsockopen(($ip ? $ip : $host), $port, $errno, $errstr, $timeout);
if(!$fp ) {
return '';//note $errstr : $errno rn
} else {
stream_set_blocking($fp, $block);
stream_set_timeout($fp, $timeout);
@fwrite($fp, $out) ;
$status = stream_get_meta_data($fp);
if(!$status['timed_out']) {
while (!feof($fp)) {
if(($header = @fgets($fp)) && ($header == "rn" || $header == "n")) {
break;
}
}
$stop = false;
while(!feof($fp) && !$stop) {
$ data = fread($fp, ($limit == 0 || $limit > 8192 ? 8192 : $limit));
$return .= $data;
if($limit) {
$limit -= strlen( $data);
$stop = $limit <= 0;
}
}
}
@fclose($fp);
return $return;
}
}
fsockopen function cannot be used, so only I can rely on other methods. Fortunately, curl is supported, and file_get_contents also supports it. After considering it, I will use curl. I modified the uc_fopen function as follows;
Copy the code The code is as follows:
function uc_fopen($url, $limit = 0, $post = '', $cookie = '', $bysocket = FALSE, $ip = '', $timeout = 15, $block = TRUE) {
$return = '';
$curl = curl_init( );
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
if($post) {
curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
}
if($cookie) {
curl_setopt($curl, CURLOPT_COOKIE, $cookie);
}
curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
curl_setopt($ curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$return = curl_exec($curl);
if (curl_errno($curl)) {
echo '
Error :
'.curl_error($curl);
}
curl_close($curl);
return $return;
}
So uc_client/client.php and uhome under modoer uc_cilent/client.php under, just modified the uc_open function, haha, it is my first time to use curl, there is still a lot of information on the Internet, so there is no obstacle, but I don’t know if this modification will affect other things, or Still to be tested. . . .
The above introduces the communication problem between ucenter and modoer under ucenter home which does not support fsockopen but supports culr environment, including the content of ucenter home. I hope it will be helpful to friends who are interested in PHP tutorials.
