HomeBackend DevelopmentPHP Tutorialphp curl get,post,cookie

类似于dreamhost这类主机服务商,是显示fopen的使用的。使用php的curl可以实现支持FTP、FTPS、HTTP HTPPS SCP SFTP TFTP TELNET DICT FILE和LDAP。curl 支持SSL证书、HTTP POST、HTTP PUT 、FTP 上传,kerberos、基于HTT格式的上传、代理、cookie、用户+口令证明、文件传送恢复、http代理通道就最常用的来说,是基于http的 get和post方法。

1、http的get实现

$ch = curl_init("http://www.domain.com/api/index.php?test=1") ;
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; // 获取数据返回
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ; // 在启用 CURLOPT_RETURNTRANSFER 时候将获取数据返回
echo $output = curl_exec($ch) ;

/* 写入文件 */
$fh = fopen("out.html", 'w') ;
fwrite($fh, $output) ;
fclose($fh) ;

2、http的post实现

$url = 'http://www.domain.com/api/' ;
$fields = array(
               'lname'=>'justcoding' ,
               'fname'=>'phplover' ,
               'title'=>'myapi',
               'age'=>'27' ,
               'email'=>'1353777303@gmail.com' ,
               'phone'=>'1353777303'
              );
//$post_data = implode('&',$fields);

//open connection
$ch = curl_init() ;
//set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL,$url) ;
curl_setopt($ch, CURLOPT_POST,count($fields)) ; // 启用时会发送一个常规的POST请求,类型为:application/x-www-form-urlencoded,就像表单提交的一样。
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields); // 在HTTP中的“POST”操作。如果要传送一个文件,需要一个@开头的文件名

ob_start();
curl_exec($ch);
$result = ob_get_contents() ;
ob_end_clean();

echo $result;

//close connection
curl_close($ch) ;

 

 

if($_GET['test'])
{
  print_r($_GET);
}

if($_POST)
{
 print_r($_POST);
}

 

 

3. php的curl传送cookie

 

两种方式:

一种是自动:

curl_setopt($curlHandle, CURLOPT_COOKIEJAR, 'cookie.txt '); //保存
curl_setopt($curlHandle, CURLOPT_COOKIEFILE, 'cookie.txt '); //读取

 

这样COOKIE会自动跟上去.
不过要分两次,一是先访问产生cookie,接着连结才能用cookie

例子:

function get_curlcuconent2($filename,$referer)
{
   $cookie_jar = tempnam('./tmp','JSESSIONID');
      
   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL, $filename);
   curl_setopt($ch, CURLOPT_HEADER, false);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

   //设置文件读取并提交的cookie路径
   curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar);
   $filecontent=curl_exec($ch);
   curl_close($ch);
      
   $ch = curl_init();
   $hostname ="www.domain.com";
   //$referer="http://www.domain.com/";
   curl_setopt($ch, CURLOPT_URL, $filename);
   curl_setopt($ch, CURLOPT_REFERER, $referer); // 看这里,你也可以说你从google来
   curl_setopt($ch, CURLOPT_USERAGENT, "www.domain.com");

   //$request = "JSESSIONID=abc6szw15ozvZ_PU9b-8r"; //设置POST参数
   //curl_setopt($ch, CURLOPT_POSTFIELDS, $request);  
   // 上面这句,当然你可以说你是baidu,改掉这里的值就ok了,可以实现小偷的功能,$_SERVER['HTTP_USER_AGENT']
   //你也可以自己做个 spider 了,那么就伪装这里的 CURLOPT_USERAGENT 吧
   //如果你要把这个程序放到linux上用php -q执行那也要写出具体的$_SERVER['HTTP_USER_AGENT'],伪造的也可以
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_jar);
   curl_setopt($ch, CURLOPT_HEADER, false);//设定是否输出页面内容
   curl_setopt($ch, CURLOPT_GET, 1); // post,get 过去

   $filecontent = curl_exec($ch);
   preg_match_all("/charset=(.+?)[NULL\"\']/is",$filecontent, $charsetarray);
   if(strtolower($charsetarray[1][0])=="utf-8")
         $filecontent=iconv( 'utf-8', 'gb18030//IGNORE' , $filecontent);
   curl_close($ch);
   return $filecontent;
}

?>

一种自定义:

$header[]= 'Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, text/html, * '. '/* ';
$header[]= 'Accept-Language: zh-cn ';
$header[]= 'User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727) ';
$header[]= 'Host: '.$你的目标HOST;
$header[]= 'Connection: Keep-Alive ';
$header[]= 'Cookie: '.$你的COOKIE串;

curl_setopt($curlHandel,CURLOPT_HTTPHEADER,$header);

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
