Communication problem between ucenter and modoer in culr environment that does not support fsockopen but supports culr_PHP tutorial

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 as follows:

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;
}
}

The fsockopen function cannot be used, so you have to rely on other methods. Fortunately, curl is supported, and file_get_contents also supports it. I decided to use curl after considering it, and 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 under modoer and uc_cilent/client.php under uchome have modified the uc_open function in this way. 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 this. Whether the modification will affect other things remains to be tested. . . .
