php curl模拟post请求提交数据例子总结

接受php页面远程服务器：

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

$cookie_jar = tempnam('/tmp','cookie');

$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);

}

2.http://www.b.com/handleUpload.php

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