form表单curl提交

Content-Type:application/x-www-form-urlencoded 支持的数据类型不是key=>valuea支持rray('field1=value&field2=value2')

/**
 * @curl 请求
 * @param $url
 * @param string $post
 * @param string $cookie
 * @param int $returnCookie
 * @return mixed|string
 */
public function curl_post($url, $post = '', $cookie = '', $returnCookie = 0)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

    if ($post != '' && !empty($post)) {
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('application/x-www-form-urlencoded', 'Content-Length: ' . strlen($post)));
    }
    curl_setopt($ch, CURLOPT_TIMEOUT, 60);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

很生气...还一种

调用 $result = createForm($this->URL, $data);

function createForm($url, $data)
{
    $str = '<!doctype html>
        <html>
            <head>
                <meta charset="utf8">
                <title>正在跳转付款页</title>
            </head>
            <body onLoad="document.pay.submit()">
            <form method="post" action="' . $url . '" name="pay">';

    foreach($data as $k => $vo){
        $str .= '<input type="hidden" name="' . $k . '" value="' . $vo . '">';
    }

    $str .= '</form>
            <body>
        </html>';
    return $str;
}
