CI 3.1.8 set_cookie() 不起作用？

Question

我知道有很多关于这个set_cookie() CI 的问题，但我找不到答案，cookie 没有显示在 Google Cookie 数据菜单中。

我知道如何阅读它，但它根本没有显示在浏览器 cookie 数据中。

在ControllerFile.php

$this->load->helper('cookie');
$cookie = array(
    'name'      => 'pre',
    'value'     => $token,
    'expire'    => 86400 * 7,
);
$this->input->set_cookie(
    $cookie['name'], $cookie['value'], $cookie['expire']
);

config.php中的设置

$config['cookie_prefix']    = 'e_';
$config['cookie_domain']    = '.localhost';
$config['cookie_path']      = '/project.com/catch/';
$config['cookie_secure']    = FALSE;
$config['cookie_httponly']  = FALSE;

这个网站项目在project.com文件夹下，是这个样子

htdocs/
---- project.com/
-------- catch/
------------ *CI files*
--------- *files*
--------- *files*
---- anotherproject.com/
---- anotherproject.com/
---- anotherproject.com/

但是[::1] 和.localhost 都没有cookie 数据，为什么会这样？

我已经尝试用谷歌搜索但找不到解决方案，我已经尝试过

$config['cookie_prefix']    = '';
$config['cookie_domain']    = '';
$config['cookie_path']      = '';
$config['cookie_secure']    = FALSE;
$config['cookie_httponly']  = FALSE;

但它也不起作用。

添加log file

如您所见，在日志文件中根本没有错误消息

希望对您有所帮助：

尝试使用数组方法（Alternative），将关联数组传递给set_cookie：

替换它

$cookie = array(
    'name'      => 'pre',
    'value'     => $token,
    'expire'    => 86400 * 7,
);
$this->input->set_cookie(
    $cookie['name'], $cookie['value'], $cookie['expire']
);

有了这个：

$cookie = array(
    'name'      => 'pre',
    'value'     => $token,
    'expire'    => 86400 * 7,
    /* no need to set domain if localhost */
    'domain' => '.localhost',
    'path'   => '/',
    'prefix' => 'e_',
    'secure' => FALSE
);
$this->input->set_cookie($cookie);

检查您的 cookie

print_r($this->input->cookie());
