简介：这是不支持fsockopen,culr支持，下ucenter 与modoer通讯问题的详细页面，介绍了和php,有关的知识、技巧、经验，和一些php源码等。
class='pingjiaF' frameborder='0' src='http://biancheng.dnbcw.info/pingjia.php?id=343925' scrolling='no'>网站上线，modoer与ucenter 下不能通讯折腾了我差不多二天，开始都以为自己的配置出问题，移植了平台后就不能通讯了，修改了几次配置，都没有成功，所以就怀疑是否编码问题，或者文件权限问题，或者是不是函数不支持问题，经过排查发现原来是万网的L1主机不支持fsockopen，在文件uc_client/client.php中的uc_fopen中出现了问题，这里的代码是这样：
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/1.0\r\n";
$out .= "Accept: */*\r\n";
//$out .= "Referer: $boardurl\r\n";
$out .= "Accept-Language: zh-cn\r\n";
$out .= "Content-Type: application/x-www-form-urlencoded\r\n";
$out .= "User-Agent: $_SERVER[HTTP_USER_AGENT]\r\n";
$out .= "Host: $host\r\n";
$out .= 'Content-Length: '.strlen($post)."\r\n";
$out .= "Connection: Close\r\n";
$out .= "Cache-Control: no-cache\r\n";
$out .= "Cookie: $cookie\r\n\r\n";
$out .= $post;
} else {
$out = "GET $path HTTP/1.0\r\n";
$out .= "Accept: */*\r\n";
//$out .= "Referer: $boardurl\r\n";
$out .= "Accept-Language: zh-cn\r\n";
$out .= "User-Agent: $_SERVER[HTTP_USER_AGENT]\r\n";
$out .= "Host: $host\r\n";
$out .= "Connection: Close\r\n";
$out .= "Cookie: $cookie\r\n\r\n";
}
$fp = @fsockopen(($ip ? $ip : $host), $port, $errno, $errstr, $timeout);
if(!$fp) {
return '';//note $errstr : $errno \r\n
} else {
stream_set_blocking($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 == "\r\n" || $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 $return;
}
}
fsockopen函数不能使用，因些就只能靠其它方法了，幸亏支持curl，file_get_contents也支持，经考虑就用curl吧，修改了uc_fopen函数，如下;
function uc_fopen($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($curl)) {
echo '<pre><b>错误:</b><br />'.curl_error($curl);
}
curl_close($curl);
return $return;
}
于是modoer下的uc_client/client.php和uchome下的uc_cilent/client.php，就这样修改了uc_open函数，呵呵，第一次使用curl，网上的资料还是好多的，所以也没有什么阻碍，不过就不知这个修改会不会影响其它的东西，还有待测试罗。。。。
