php 使用curl 进行简单模拟提交表单

//初始化curl
$ch = curl_init();
$url = ‘xxx‘;
$option = [
    CURLOPT_URL => $url,
    CURLOPT_HEADER => 1,
    CURLOPT_RETURNTRANSFER => 1,
];
curl_setopt_array($ch, $option);
$output = curl_exec($ch);
preg_match_all(‘/Set-Cookie: (.*);/i‘, $output, $str); //正则匹配
//如果有token的话就获取token
preg_match(‘/token = \"(.*)\"/i‘, $output, $token);
if (empty($str)) {
    return false;
}
$cook = $str[1];
$cookie = implode(‘;‘, $cook);

$up_url = ‘xxx‘;
$post_data = [
    ‘name‘ => ‘test_‘,
    ‘tel‘ => ‘18819271234‘,
    ‘email‘ => ‘qqhahadfdfads@163.com‘,
    ‘message‘ => ‘this is my message;‘,
    ‘_token‘ => $token[1],
];
$options = [
    CURLOPT_URL => $up_url,
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_HEADER => 1,
    CURLOPT_USERAGENT => "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.96 Safari/537.36",
    CURLOPT_COOKIESESSION => 1,
    CURLOPT_POST => 1,
    CURLOPT_POSTFIELDS => $post_data,
    CURLOPT_COOKIE => $cookie
];
curl_setopt_array($ch, $options);
$res = curl_exec($ch);
// $info = curl_getinfo($ch);
if ($res === FALSE) {
    p(‘curl Error: ‘ . curl_error($ch));
}
curl_close($ch);
p($res);
