推荐答案

假设两个应用程序都在CodeIgniter上 - 您必须同意您的应用程序和第三方之间的一些参数

Assuming both applications are on CodeIgniter - You must agree upon some parameters between your application and the third-party that will be issuing the cookie.

进入 config / config.php 并设置双方最少）：

Head into config/config.php and have both parties set (at the least):

$ config ['sess_cookie_name'] 和 $ config ['cookie_prefix '] 为相同的值。

如果您决定加密会话，您还必须同意第三方和您的应用程序，并适当设置 $ config ['encryption_key'] 值。

If you decide to encrypt your session, you must also agree upon an encryption key between the third party and your application and set the $config['encryption_key'] value appropriately.

最后， ，您必须设置cookie域， $ config ['cookie_domain'] 或CodeIgniter将拒绝它。

Lastly, and perhaps most importantly, you must set the cookie domain, $config['cookie_domain'] or CodeIgniter will reject it.

然后，您可以使用 $ this-> session-> userdata（） $ this-> session-> set_userdata（）。

，所以我不能真正保证或支持可能出现的任何问题，但希望它设置你在一些成功的路径。

I've never tried this before, so I can't really vouch or support to great length any issues that may arise, but hopefully it sets you on the some path to success.
