Look at the documentation: Codeigniter Cookie Helper Guide
查看文档：Codeigniter Cookie Helper Guide
It says that you should use $this->input->cookie()to retrieve a cookie:
它说你应该$this->input->cookie()用来检索cookie：
$this->input->cookie('test_cookie', TRUE);

This worked for me on localhost, security might need tightened for server
这在本地主机上对我有用，服务器的安全性可能需要加强
$this->load->helper('cookie');
$cookie = array(
'name' => 'data',
'value' => '23',
'expire' => 86500,
'secure' => false
);
$this->input->set_cookie($cookie);
var_dump($this->input->cookie('data', false));
Expire needs to be numeric, removed path and set secure to false
过期需要是数字，删除路径并将安全设置为false

If you are using google chrome use inspect element to see if the cookie has been set... I think you can do it in FF, but I haven't used FF in a while... I only had one issue with cookies and that was I was setting domain to my live domain... So I have my cookie code like this:
如果您正在使用谷歌浏览器，请使用检查元素来查看 cookie 是否已设置...我认为您可以在 FF 中执行此操作，但我有一段时间没有使用 FF...我只有一个 cookie 问题，并且那是我将域设置为我的实时域......所以我有这样的 cookie 代码：
$this->load->helper('cookie');
$cookie = array(
'name' => 'the_cookie',
'value' => 'test value here',
'expire' => '15000000',
'prefix' => ''
);
$this->input->set_cookie($cookie);
Here you can see it is showing up in Google Chrome "Inspect Element Tool"
在这里你可以看到它显示在谷歌浏览器的“检查元素工具”中

'secure' => TRUE
This does not allow me to fetch the cookie.
这不允许我获取 cookie。
just set
刚刚设置
'secure' => FALSE
and see it may work.
看看它可能会起作用。

setting the security => TRUEwill not allow to print the cookie value in local, it only grant access to secure connections only so it will not print anything in localhost for you unless you set the security => FALSEthan using codeigniter CI_Inputclass you can get the value of cookie
设置security => TRUE将不允许在本地打印 cookie 值，它仅授予对安全连接的访问权限，因此它不会为您在 localhost 中打印任何内容，除非您设置了security => FALSE使用 codeigniter CI_Input类，您可以获得 cookie 的值
$this->input->cookie('cookie_name', TRUE); //with xss filtering
$this->input->cookie('cookie_name'); //without xss filtering

If the code mentioned below does not provide any output, then modify the application/config/config.phpfile and setting this:
如果下面提到的代码没有提供任何输出，那么修改 application/config/config.php文件并设置：
$config['global_xss_filtering'] = TRUE;
$this->input->cookie('cookie_name', TRUE);
else just use this it will display the value
否则只需使用它就会显示值
$this->input->cookie('cookie_name');

Load the cookie helper with:
加载 cookie 助手：
$this->load->helper('cookie');
Then retrieve your cooking with:
然后使用以下命令检索您的烹饪：
$cookieData = get_cookie("cookie_name");
Note, these are aliases to using the input class, you can also retrieve and set cookies like so:
请注意，这些是使用输入类的别名，您还可以像这样检索和设置 cookie：
$cookieData = $this->input->get_cookie("cookie_name");
