php模拟post表单提交的问题

[lizyl]

一下是我用socket模拟表单提交的代码，
而在构造参数的时候，我想构造一个多维数组，
比如正常的页面提交数据的时候，控件名称肯能是h1[password],h1[username].像这样的数据我怎么加入我的参数数组中呢？或者是post数据中是以什么方式传递的。
我用
$argv = array(
'address_box'=>'www.baidu.com',
'submit'=>'submit',
'h1'=>array('include_form'=>1)
);
这样的形式，不成功。

$flag = 0;

//要post的数据
$argv = array(
'address_box'=>'www.baidu.com',
'submit'=>'submit',
'h1'=>array('include_form'=>1)
);
$params="";
//构造要post的字符串
foreach ($argv as $key=>$value){
if ($flag!=0){
$params .= "&";
$flag = 1;
}else {
$params="";
}

$params.= $key."=";
//$params.= urlencode($value);
$params.= $value;
$flag = 1;
}

$length = strlen($params);

//创建socket连接
$fp = fsockopen("www.golookitupyourdamnself.com",80,$errno,$errstr,10) or exit($errstr."—>".$errno);

//构造post请求的头
$header = "POST /index.php HTTP/1.1\r\n";
$header .= "Host:www.golookitupyourdamnself.com\r\n";
$header .= "Referer:/index.php\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: ".$length."\r\n";
$header .= "Connection: Close\r\n\r\n";

//添加post的字符串
$header .= $params."\r\n";

想模拟登陆后获得相关信息？
可以参考snoopy 来做 这个封装的不错 ^_^

不知道你遇到了什么问题，按照你的代码
$flag = 0;

foreach ($argv as $key=>$value){
if ($flag!=0){ //因为 $flag 为 0 此分支永远不会进入
$params .= "&";
$flag = 1;
}else {
$params="";
}

$params 永远为空

'h1'=>array('include_form'=>1)
???

頂一下!

[freespacezjx]

怎么个不成功? 是页面没有输出?
不知道你在代码里面是否echo $header ,这样才会把请求的结果显示,
还有你的params 中第一个key 和value 会加不进去(不知是否故意不加的)

构造参数用 http_build_query 函数

给你一个函数

function sock_post($url, $data='') {
  $url = parse_url($url);
  $url['scheme'] || $url['scheme'] = 'http';
  $url['host'] || $url['host'] = $_SERVER['HTTP_HOST'];
  $url['path'][0] != '/' && $url['path'] = '/'.$url['path'];

  $query = $data;
  if(is_array($data)) $query = http_build_query($data);

  $fp = @fsockopen($url['host'], $url['port'] ? $url['port'] : 80);
  if (!$fp) return "Failed to open socket to $url[host]";

  fputs($fp, sprintf("POST %s%s%s HTTP/1.0\n", $url['path'], $url['query'] ? "?" : "", $url['query']));
  fputs($fp, "Host: $url[host]\n");
  fputs($fp, "Content-type: application/x-www-form-urlencoded\n");
  fputs($fp, "Content-length: " . strlen($query) . "\n");
  fputs($fp, "Connection: close\n\n");

  fputs($fp, "$query\n");

  $line = fgets($fp,1024);
  if (!eregi("^HTTP/1\.. 200", $line)) return;

  $results = ""; $inheader = 1;
  while(!feof($fp)) {
    $line = fgets($fp,1024);
    if ($inheader && ($line == "\n" || $line == "\r\n")) {
      $inheader = 0;
    }elseif (!$inheader) {
      $results .= $line;
    }
  }
  fclose($fp);

  return $results;
}

测试代码
echo sock_post("ajax_server.php?id=1",array(a=>"123",b=>"a bc", array('c'=>'测试')));
输出
post Array ( [a] => 123 [b] => a bc [0] => Array ( [c] => 测试 ) ) get Array ( [id] => 1 )

其中 ajax_server.php
<?php
echo 'post';
print_r($_POST);
echo 'get';
print_r($_GET);
?>

$argv = array(
	'h1' => array('username' => 'Jerry', 'password' => '123456')
	); 
foreach($argv['h1'] as $key => $value) {
	$params[] = $key . '=' . $value;
}
$params = implode('&', $params);

$header = "POST /post.php HTTP/1.1\r\n";
$header .= "Host:localhost\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($params) . "\r\n";
$header .= "Connection: Close\r\n\r\n"; 
$header .= $params;

$fp = fsockopen('localhost', '80');
fputs($fp, $header);

while(!feof($fp)) {
	echo fgets($fp);
}
