【问题描述】：

我认为问题可能来自 LanguageControl。通过一直重复 url 来刷新页面。我在管理面板中使用多语言支持。以下是我认为可能存在问题的所有代码块。

路线

$routes->get('/', 'Frontend\Home::index', ['as' => 'homepage']);

控制器

class Home extends BaseController
{
    public function index()
    {
        return sdc_theme_view('index');
    }
}

sdc_theme_view

function sdc_theme_view($path, $data = [])
{
    $viewPath = THEMES_PATH . sdc_theme_folder();
    $renderer = \Config\Services::themeRenderer($viewPath, null, true);
    $shortcoder = new \Seiler\Shortcoder\Shortcoder();
    $shortcoder->add(shortcodes());
    return $shortcoder->parse($renderer->setData($data)->render($path));
}

语言控制

class LanguageControl implements FilterInterface
{
    public function before(RequestInterface $request, $arguments = null)
    {
        $referer = (string) Services::request()->getServer('HTTP_REFERER');

        $_SESSION['_ci_previous_url'] = $referer;

        $uri = new \CodeIgniter\HTTP\URI(current_url());

        $segments = $uri->getSegments();

        if (!isset($segments[0]) || !in_array($segments[0], config('app')->supportedLocales)){
            array_unshift($segments, config('app')->defaultLocale);
            $query = $uri->getQuery();
            $new_uri = implode('/', $segments);
            $new_uri = $query ? $new_uri . '?'. $query : $new_uri;
            return redirect()->to(base_url($new_uri));
        }
    }

.env

app.baseURL = 'http://localhost/sdcms/'

【解决方案1】：

我很确定您需要替换 array_unshift。对我来说，当我设置你的代码时，我需要查看 $segments[1] 如果你需要稍微调整一下，请原谅我：

unset($segments[1]);
$segments[] = $defaultLocale;

您的示例的完整代码（但使用 $variables 作为您支持的默认语言环境）：

public function before(RequestInterface $request, $arguments = null){
    $uri = new \CodeIgniter\HTTP\URI(current_url());

    $segments = $uri->getSegments();

    $supportedLocales = array('en','fr');
    $defaultLocale = 'en';

    if (!isset($segments[1]) || !in_array($segments[1],$supportedLocales)){
        unset($segments[1]);
        $segments[] = $defaultLocale;

        $query = $uri->getQuery();
        $new_uri = implode('/', $segments);
        $new_uri = $query ? $new_uri . '?'. $query : $new_uri;

        return redirect()->to(base_url($new_uri));
    }
}

如果我遗漏了什么，请告诉我。
