要么文件权限难题,复制代码 代码如下凯时国际

 代码如下

本文实例讲述了php使用fsockopen函数发送post,get请求获取网页内容的方法。分享给大家供大家参考。

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:

$post =1;
$url = parse_url($url);
$host ='';
$path ='/';
$query ='?action=111cn.net';
$port =80;
 
if($post) {
  $out = "post $path http/1.0 ";
  $out .= "accept: */* ";
  //$out .= "referer: $boardurl ";
  $out .= "accept-language: zh-cn ";
  $out .= "content-type: application/x-www-form-urlencoded ";
  $out .= "user-agent: $_server[http_user_agent] ";
  $out .= "host: $host ";
  $out .= 'content-length: '.strlen($post)." ";
  $out .= "connection: close ";
  $out .= "cache-control: no-cache ";
  $out .= "cookie: $cookie ";
  $out .= $post;
 } else {
  $out = "get $path http/1.0 ";
  $out .= "accept: */* ";
  //$out .= "referer: $boardurl ";
  $out .= "accept-language: zh-cn ";
  $out .= "user-agent: $_server[http_user_agent] ";
  $out .= "host: $host ";
  $out .= "connection: close ";
  $out .= "cookie: $cookie ";
 }
 $fp = @fsockopen(($ip ? $ip : $host), $port, $errno, $errstr, $timeout);
 if(!$fp)
 {
  return '';//note $errstr : $errno
 } else {
  return '成功访问';
 }
 /*
 fsockopen语法
 
 resource fsockopen ( string $hostname [, int $port = -1 [, int &$errno [, string &$errstr [, float $timeout = ini_get("default_socket_timeout") ]]]] )

具体实现代码如下:

复制代码 代码如下:

 
 启动一个套接字连接到指定的主机的资源。
    php支持在互联网领域的目标和unix在所支持的套接字传输列表说明。所支持的传输列表也可以检索使用stream_get_transports()。
 
 该插座预设会被启用,阻塞模式。你可以切换到非阻塞模式使用stream_set_blocking()。
 
 如果上面实例看不懂,就来看个简的吧

复制代码 代码如下:

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'] ? '?'.$matches['query'] : '') : '/';
凯时国际ag下载,$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 .= $post;
} else {

$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;

 

fsockopen语法:
