Codeigniter 和 AngularJS 错误:当应用程序不在根目录中时,分页不起作用

Raz*_*fir 5 php codeigniter angularjs

我正在使用Codeigniter 3.1.8AngularJS v1.7.8开发一个博客应用程序

应用程序的仪表板是“纯粹的”Codeigniter,具有模型、控制器和视图,而前端由 AngularJS 管理和显示的 JSON 组成。(我在后端和前端之间进行了这种明确的分离,以启用“主题化”。)

帖子是分页的。在后端,在Posts 控制器中,帖子列表如下所示:

private function _initPagination($path, $totalRows, $query_string_segment = 'page') {
  //load and configure pagination 
    $this->load->library('pagination');
    $config['base_url'] = "http://".$_SERVER['HTTP_HOST'] . $path;
    $config['query_string_segment'] = $query_string_segment; 
    $config['enable_query_strings'] =TRUE;
    $config['reuse_query_string'] =TRUE;
    $config['total_rows'] = $totalRows;
    $config['per_page'] = 12;
    if (!isset($_GET[$config['query_string_segment']]) || $_GET[$config['query_string_segment']] < 1) {
        $_GET[$config['query_string_segment']] = 1;
    }
    $this->pagination->initialize($config);

    $limit = $config['per_page'];
    $offset = ($this->input->get($config['query_string_segment']) - 1) * $limit;

    return ['limit' => $limit, 'offset' => $offset];
}

public function index() {

  //call initialization method
    $config = $this->_initPagination("/", $this->Posts_model->get_num_rows());

    $data = $this->Static_model->get_static_data();
    $data['pagination'] = $this->pagination->create_links();
    $data['pages'] = $this->Pages_model->get_pages();
    $data['categories'] = $this->Categories_model->get_categories();  

  //use limit and offset returned by _initPaginator method
    $data['posts'] = $this->Posts_model->get_posts($config['limit'], $config['offset']);

    // All posts
    $this->output->set_content_type('application/json')->set_output(json_encode($data,JSON_PRETTY_PRINT));
}

在前端,在 AngularJS 中,我有:

 // All posts
.controller('PostsController', ['$scope', '$http', function($scope, $http){

    //Get current page (?page=2, ?page=3 etc)
    const currPage = window.location.search;

    // Get all the posts on the current page 
    $http.get('api/' + currPage).then(function(response) {

        //Categories
        $scope.categories = response.data.categories;

        // Posts
        $scope.posts = response.data.posts;

        // posts pagination
        $scope.pagination = response.data.pagination;

    });
}])

问题是当应用程序不在根目录中(它位于 www.examplesite.com/blog,而不是 www.examplesite.com)时,分页不起作用(链接指向错误的链接)。

我想它与 Codeigniter 有关系,base_url()但我无法发现错误并修复它。

我该如何解决这个问题?

看看这一行:

$config = $this->_initPagination("/", $this->Posts_model->get_num_rows());

这指定了路径 as "/",它被传递为$path,所以在你function的链接路径将是

$config['base_url'] = "http://".$_SERVER['HTTP_HOST'] . $path;

它只会在根 URL 的末尾放置一个 / 。您需要在 index 处传递正确的后缀,而不是"/"在不在 root上时传递。

问题就在这里:

$config['base_url'] = "http://".$_SERVER['HTTP_HOST'] . $path;

因为$_SERVER['HTTP_HOST']始终是根目录,没有其他目录。

你需要使用类似的东西:

$config['base_url'] = str_replace("/api/", "/", base_url()) . $path;

但我建议你在前端(Angular)中实现分页,而在 CI 中你只需要类似的东西:

public function index($offset, $limit) {
    $data = [];
    $data['count'] = $this->Posts_model->get_num_rows();
    $data['pages'] = $this->Pages_model->get_pages();
    $data['categories'] = $this->Categories_model->get_categories();  
    $data['posts'] = $this->Posts_model->get_posts($limit, $offset);

    $this->output->set_content_type('application/json')->set_output(json_encode($data,JSON_PRETTY_PRINT));
