在 cUrl url 中使用 $_POST["username"]

Question

我有一个基本形式的页面：

<form action="r.php" method="post">
    <span>
    <input type="text" placeholder="Notch" id="minime_url_textbox" name="u">
    <label class="btn1 btn2 btn-2 btn-2g"> <input name="submit" type="submit" id="submit" value="Resolve"> </label>
    <div class="clearfix"> </div>
    </span>
    </form>

当他们在输入框中输入用户名时按回车，他们会重定向到一个 r.php，它有一个包含（）的 php 文件，其中包含：

<?php
//Urls to scrape from.
$user = isset($_GET['u']) ? $_GET['u'] : 'safetrbgds';

$URLs = array();
$URLs[] = 'http://namemc.com/u/'.$user;
$working = '';

//Curl scraper.
foreach($URLs as $URL){
    $ch     = curl_init();
    curl_setopt($ch, CURLOPT_URL, $URL);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 1);        
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    $page = curl_exec($ch);
    $text = strip_tags($page);
    $accounts = array();
    preg_match_all('/(\w+) \s+ is \s+ available/x',$text,$accounts);
    foreach($accounts[0] as $account){
        $working .= ''.$account.''. PHP_EOL . '';
    }
}

//Put the scraped proxies into the new .txt file.
file_put_contents('accounts.txt', $working, FILE_APPEND);
?>

它确实适用于 $user = isset($_GET['u']) 吗？ $_GET['u'] : 'safetrbgds'; 对于 safetrbgds，但不适用于用户实际输入的内容。

我试过了：

$URLs[] = 'http://namemc.com/u/{$_POST["username"];}';

我只需要它来结束渲染，例如： $URLs[] = 'http://namemc.com/u/test';

<?php
//Urls to scrape from.
$user = isset($_POST['u']) ? $_POST['u'] : 'safetrbgds';

$URL = 'http://namemc.com/u/'.$user;
$working = '';

    $ch     = curl_init();
    curl_setopt($ch, CURLOPT_URL, $URL);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 1);        
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    $page = curl_exec($ch);
    $text = strip_tags($page);
    $accounts = array();
    preg_match_all('/(\w+) \s+ is \s+ available/x',$text,$accounts);
    foreach($accounts[0] as $account){
        $working .= ''.$account.''. PHP_EOL . '';
    }


//Put the scraped proxies into the new .txt file.
file_put_contents('accounts.txt', $working, FILE_APPEND);
?>

试试这个。

这是包含您需要的所有数据的解决方案。

<?php
//Urls to scrape from.
$user = isset($_POST['u']) ? $_POST['u'] : 'safetrbgds';
$URL = 'http://namemc.com/u/'.$user;
$ch     = curl_init();
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, 1);        
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$page = curl_exec($ch);
$accounts = array();
preg_match_all('/<div class="alert alert-.*" role="alert">(.*)<\/div>/',$page,$accounts);
$data = !empty($accounts[0][0]) ? $accounts[0][0] : false;
$data = strip_tags($data, '<p></p>');
$data = str_replace('To visit Mojang and grab this name, click here.', '', $data);
$data = str_replace('<p style="margin-top: 0.5em">Want this name? Worried someone else will get it first? Snipe it with www.mcsniper.com! (Advertisement)</p>','',$data);
$data = str_replace('<p>', '',$data);
$data = str_replace('</p>', '',$data);
$data = $data.PHP_EOL;
file_put_contents('accounts.txt', $data, FILE_APPEND);
?>

输出accounts.txt
