我想在我的 ci 3.03 应用程序中使用 restful:
- 我找到了这个tutplus 教程
- 我下载了
codeigniter-restserver-master.zip
文件并将Format.php
文件复制REST_Controller.php(@version 3.0.0)
到/application/libraries/REST directory
我创建了控制应用程序/控制器/api/Users.php:
require_once("application/libraries/REST/REST_Controller.php"); require_once("application/libraries/REST/Format.php"); class Users extends REST_Controller { //protected $rest_format = 'json'; function users_get() { //$users = $this->user_model->get_all(); $filter_username= $this->get('filter_username'); $filter_user_group= $this->get('filter_user_group'); $filter_active= $this->get('filter_active'); $sort= $this->get('sort'); $sort_direction= $this->get('sort_direction'); //, $filter_user_group, $filter_active, $sort, $sort_direction $users_list = $this->muser->getUsersList(false, ''/*, $filter_username, $filter_user_group, $filter_active, $sort, $sort_direction, ''*/); echo '<pre>'.count($users_list).'::$users_lists::'.print_r($users_list,true).'</pre>'; if($users_list) { $this->response($users, 200); } else { $this->response(NULL, 404); } }
和运行 URL http://local-ci3.com/api/users我有很多错误:
遇到 PHP 错误

实际上,我想获得一些可行的库来帮助我创建 REST api。我认为这是更可取的方式,而不是从零开始。但是这个库是不可用的还是需要一些修复?抱歉,我错过的是这个库是否仅适用于 ci 2?
我在这个论坛上进行了搜索,发现了这样的提示:
当我将 Format.php 和 Rest_Controller.php 加载到控制器中时,我遇到了同样的问题。快速浏览 Format.php 后,它似乎是一个独立的格式转换助手。尝试仅加载 Rest_Controller.php 并查看您的问题是否消失。
我评论了行
//require_once("application/libraries/REST/Format.php");
在我的控制器中,但我仍然收到如下错误:消息:未定义属性:用户::$格式。我试图查看这个库的代码,并在数据转换为 json 格式时看到无效块,第 731-757 行:
elseif ($data !== NULL)
{
// If the format method exists, call and return the output in that format
if (method_exists($this->format, 'to_' . $this->response->format))
{
// Set the format header
$this->output->set_content_type($this->_supported_formats[$this->response->format], strtolower($this->config->item('charset')));
$output = $this->format->factory($data)->{'to_' . $this->response->format}();
// An array must be parsed as a string, so as not to cause an array to string error
// Json is the most appropriate form for such a datatype
if ($this->response->format === 'array')
{
$output = $this->format->factory($output)->{'to_json'}();
}
}
else
{
// If an array or object, then parse as a json, so as to be a 'string'
if (is_array($data) || is_object($data))
{
$data = $this->format->factory($data)->{'to_json'}();
}
// Format is not supported, so output the raw data as a string
$output = $data;
}
}
如果我试图评论这个块,但得到错误
Message: Array to string conversion
看起来在这种情况下数据没有转换......
是否可以修复这些错误?或者你能告诉我一些codeigniter 3 REST api 可用库的建议吗?这些库具有类似的接口,如上面的库?
谢谢!
