如何在codeigniter中创建Rest API

Question

为了创建简单的Rest API，我按照以下步骤下载了CodeIgniter-restserver，并从下载的文件中将粘贴的REST_Controller复制到我的项目下的库中(src是项目名称)。然后在我的项目的控制器内部创建了Api.php

<?php
require(APPPATH'.libraries/REST_Controller.php');

class API extends REST_Controller {

    function test()
    {
        echo "RESTfull API";
    }
}
?>

And I run the URLhttp://localhost/src/index.php/Api/test in postman，但未显示结果。

你需要点击下面的链接https://itsolutionstuff.com/post/codeigniter-3-restful-api-tutorialexample.html

然后，在运行代码之后，您将得到一个无法加载所请求的语言文件的小错误: language/english/rest_controller_lang.php

问题是codeigniter找不到rest_controller翻译。您只需要创建这个文件/application/languages/english/rest_controller_lang.php

然后将此代码复制并粘贴到其中：

<?php
/*
 * English language
 */
$lang['text_rest_invalid_api_key'] = 'Invalid API key %s'; // %s is the REST API key
$lang['text_rest_invalid_credentials'] = 'Invalid credentials';
$lang['text_rest_ip_denied'] = 'IP denied';
$lang['text_rest_ip_unauthorized'] = 'IP unauthorized';
$lang['text_rest_unauthorized'] = 'Unauthorized';
$lang['text_rest_ajax_only'] = 'Only AJAX requests are allowed';
$lang['text_rest_api_key_unauthorized'] = 'This API key does not have access to the requested controller';
$lang['text_rest_api_key_permissions'] = 'This API key does not have enough permissions';
$lang['text_rest_api_key_time_limit'] = 'This API key has reached the time limit for this method';
$lang['text_rest_ip_address_time_limit'] = 'This IP Address has reached the time limit for this method';
$lang['text_rest_unknown_method'] = 'Unknown method';
$lang['text_rest_unsupported'] = 'Unsupported protocol';

请逐行阅读this article。这是初学者使用CodeIgniter Rest API库的最佳解决方案。

<?php
require(APPPATH.'/libraries/REST_Controller.php');

class API extends REST_Controller {

    function test_get()
    {

    $data = array("message"=>"RESTfull API");
    $this->response($data);
    }
}
?>

联系方式：http://localhost/src/index.php/Api/test

注意：在rest API中，您应该将方法类型定义为GET, POST, PUT, and DELETE

希望这能对你有所帮助:

require APPPATH . '/libraries/REST_Controller.php';
class Api extends REST_Controller {

    function test_get()
    {
      $data = array('response' => 'RESTfull API');

      if(count($data ) > 0)
      {
         $this->response($data ,REST_Controller::HTTP_OK);
      }
      else
      {
         $error = array('message' => 'No record found');
         $this->response($error,REST_Controller::HTTP_OK);
      }   
}
