如何在 CodeIgniter 中读取 QueryString? [英] How can I read a QueryString in CodeIgniter?

问题描述

我知道之前有人问过它，但我需要它来进行会员跟踪...

I know it's been asked before, but I need it for affiliate tracking...

http://www.mysite.com/controller/method/params?affiliate=123&sub_id=456

如何获取该 URL 中列出的参数和 $_GET 参数?

How can I get the params AND the $_GET parameters outlined in that URL?

推荐答案

然而，有时 您需要访问 CodeIgniter 中的 GET 变量.

一个明显的例子是当您使用 API 向您的网站(Paypal 等)发送回发消息时

One glaring example is when you use an API that sends a post-back to your site (Paypal, etc.)

在我看来，最简单的方法是使用您需要的 GET 数据解析服务器变量，因为 $_GET 已被擦除(在我的示例中，REQUEST_URI 具有我的 GET 数据.):

The easiest way, in my opinion, is to parse a server variable with the GET data you need since $_GET has been wiped (in my example, REQUEST_URI has my GET data.):

parse_str(substr(strrchr($_SERVER['REQUEST_URI'], "?"), 1), $_GET);

这允许在您需要的地方使用功能，而无需对框架设置进行全局更改.

This allows the functionality exactly where you need it without requiring a global change to framework settings.

这是一个用法示例.

class Pgate extends Controller {
   function postback() {
      parse_str(substr(strrchr($_SERVER['REQUEST_URI'], "?"), 1), $_GET);
      $receipt = $this->input->xss_clean($_GET['receipt']);
   }
}
