foreach循环内的卷曲请求方法出错

Question

当我使用foreach（选项1）而不是重复代码（选项2）时，出现错误“未定义偏移量：1”。对于foreach，我仅使用带有2个字符串的数组进行测试。错误在$html_tt = get($direct_link_tt[1]);行上。我应该在get方法上做些不同的事情吗？

$cookie_path = dirname(__FILE__).'/cookie.txt';

function login($user, $pass, $account) {
  $URL = 'https://example.com/index.php';
  global $cookie_path;
  $ch = curl_init($URL);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, 'url_login='.$user.'&url_password='.$pass.'&url_account='.$account);
  curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_path);
  curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_path);
  $ret = curl_exec($ch);
  curl_close($ch);

  return $ret;
}

function get($url) {
  global $cookie_path;
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
  curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_path);
  curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_path);
  $html = curl_exec($ch);
  curl_close($ch);

  return $html;
}

function main() {
    $user = 'XXXXXX';

我做错了什么？

Answer 1

我认为您需要使用两个不同的变量来初始化两个curl请求。

function login($user, $pass, $account) {
  $URL = 'https://example.com/index.php';
  global $cookie_path;
  $ch = curl_init($URL);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, 'url_login='.$user.'&url_password='.$pass.'&url_account='.$account);
  curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_path);
  curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_path);
  $ret = curl_exec($ch);
  curl_close($ch);

  return $ret;
}

function get($url) {
  global $cookie_path;
  $ch2 = curl_init();
  curl_setopt($ch2, CURLOPT_URL, $url);
  curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch2, CURLOPT_CONNECTTIMEOUT, 10);
  curl_setopt($ch2, CURLOPT_COOKIEJAR, $cookie_path);
  curl_setopt($ch2, CURLOPT_COOKIEFILE, $cookie_path);
  $html = curl_exec($ch2);
  curl_close($ch2);

  return $html;
}

希望对您有帮助。
