php 模拟get提交
方法一:
$re = file_get_contents($url); print_r($re);
方法二:
$ch = curl_init("http://www.jb51.net/") ;
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ;
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ;
$output = curl_exec($ch) ;
$fh = fopen("out.html", 'w') ;
fwrite($fh, $output) ;
fclose($fh) ;方法三:
function dfopen($url, $limit = 0, $post = '', $cookie = '', $bysocket = FALSE , $ip = '', $timeout = 15, $block = TRUE, $encodetype = 'URLENCODE') {
$return = '';
$matches = parse_url($url);
$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 .= "Accept-Language: zh-cn\r\n";
$boundary = $encodetype == 'URLENCODE' ? '' : ';'.substr($post, 0, trim(strpos($post, "\n")));
$out .= $encodetype == 'URLENCODE' ? "Content-Type: application/x-www-form-urlencoded\r\n" : "Content-Type: multipart/form-data$boundary\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 .= "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 '';
} 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 $return;
}
}================================================================下面是我用到的,可能和上面有重复,主要是https的问题
php中curl函数可以实现get与post操作，我们经常使用它来做一些人为模仿操作了，下面我来简单的介绍post与get的例子。
get 方法
| 代码如下 | 复制代码 |
| curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 要求结果为字符串且输出到屏幕上 curl_setopt($ch, CURLOPT_HEADER, 0); // 不要http header 加快效率 curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)'); curl_setopt($ch, CURLOPT_TIMEOUT, 15); $output = curl_exec($ch); curl_close($ch); var_dump($output); |
post 方法
| 代码如下 | 复制代码 |
| $ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 要求结果为字符串且输出到屏幕上 curl_setopt($ch, CURLOPT_HEADER, 0); // 不要http header 加快效率 curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)'); curl_setopt($ch, CURLOPT_TIMEOUT, 15); curl_setopt($ch, CURLOPT_POST, 1); // post 提交方式 curl_setopt($ch, CURLOPT_POSTFIELDS, $params); $output = curl_exec($ch); curl_close($ch); var_dump($output); |
当请求https的数据时，会要求证书，这时候，加上下面这两个参数，规避ssl的证书检查
| 代码如下 | 复制代码 |
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https请求 不验证证书和hosts curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); |
