php curl如何模拟post请求提交数据？

print_r($return);

接受php页面远程服务器：

<?php
if(isset($_POST[‘name’])){
if(!empty($_POST[‘name’])){
echo ‘您好，’,$_POST[‘name’].’！’;
}
}
?>

$filename = $argv[1];
$start_num= $argv[2];
$end_num  = $argv[3];

for($i=$start_num; $i<$end_num; $i++){
$zip = sprintf(‘6s’,$i);

$fields_post = array(
‘postcode’ => $zip,
‘queryKind’ => 2,
‘reqCode’ => ‘gotoSearch’,
‘search_button.x’=>37,
‘search_button.y’=>12
);

$fields_string = http_build_query ( $fields_post, ‘&’ );
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, “URL?reqCode=gotoSearch&queryKind=2&postcode=”.$zip);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120 );
curl_setopt($ch, CURLOPT_REFERER, $refer );
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers_login );
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_jar );
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_jar );
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER[‘HTTP_USER_AGENT’]);
curl_setopt($ch, CURLOPT_POST, 1); // 发送一个常规的Post请求
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string );

$data = curl_exec($ch);
preg_match_all(‘/id=”table1″>[s]*?<tr>[s]*?<td class=”maintext”>[sS]*?</td>[s]*?</tr>/’, $data, $matches);
if (!$handle = fopen($filename, ‘a+’)) {
echo “不能打开文件 $filename”;
echo “n”;
exit;
}

if (fwrite($handle, $matches[0][1]) === FALSE) {
echo “不能写入到文件 $filename”;
echo “n”;
exit;
}

echo “成功地将 $somecontent 写入到文件$filename”;
echo “n”;

fclose($handle);
curl_close($ch);
}

class runtime
{
var $StartTime = 0;
var $StopTime = 0;
function get_microtime()
{
list($usec,$sec)=explode(‘ ‘,microtime());return((float)$usec+(float)$sec);
}
function start()
{
$this->StartTime=$this->get_microtime();
}
function stop(){
$this->StopTime=$this->get_microtime();
}
function spent()
{
return ($this->StopTime-$this->StartTime);
}
}

$runtime->stop ();

$con = ‘Processed in’.$runtime->spent().’seconds’;
echo ‘Processed in’. $runtime->spent().’seconds’;

发送POST请求

function execUpload(){

$file = ‘/doucment/Readme.txt’;
$ch = curl_init();
$post_data = array(
‘loginfield’ => ‘username’,
‘username’ => ‘ybb’,
‘password’ => ‘123456’,
‘file’ => ‘@d:usrwwwtranslatedocumentReadme.txt’
);
curl_setopt($ch, CURLOPT_HEADER, false);
//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($ch, CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_BINARYTRANSFER,true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$post_data);
curl_setopt($ch, CURLOPT_URL, ‘http://www.b.com/handleUpload.php’);
$info= curl_exec($ch);
curl_close($ch);

print_r($info);

}

function handleUpload(){
print_r($_POST);
echo ‘===file upload info:’;
print_r($_FILES);
}
