我犯了一个错误

error_log: Could not set cookie. Headers already sent.
Fatal error: Uncaught OAuthException: (#100) link URL is not properly formatted thrown in /home/admin/facebook.php on line 453

这个脚本在一个月前就开始工作了，所以只是再次上传了它，然后出现了一个错误。这是一个定制脚本，所以donno出了什么问题，所以我想问一下。这是我的密码

在设置标题之前，您已经开始“回显”输出。第453行的Facebook.php正在尝试设置一些响应标题，但它无法，因为已经设置了标题，并且响应主体已经启动

在执行第453行之前，请确保您没有

echo

、

var\u dump

、

pr

或向浏览器输出任何内容

 // results are returned, errors are thrown
    if (is_array($result) && isset($result['error'])) {
      $e = new FacebookApiException($result);
      if ($e->getType() === 'OAuthException') {
        $this->setSession(null);
      }
      throw $e;
    }
    return $result;
  }
