Codeigniter：发布在Codeigniter apis中不起作用的数据

问题描述：

i am using following code to test posting of data but post data is always empty i tried to test using postman but it did not work , following is a test code that i wrote but it always goes to else block , i tried writing else if as well but it did not work

class Api_home extends CI_Controller{
    function __construct(){
        parent::__construct();

        $this->load->model('Api_model','api');
        $this->load->helper('form');
            $data= array(
                'message'   => ' Something went wrong', 
                'status'    =>1, 
                'data'      =>'', 
            ); 
    }
        public function test(){

            $lang= $this->input->post['lang'];
            if($lang=="ar"){
                $this->data['message']= 'Arabic test';
            } 
                    //else if 
                   // else if($lang=="en")
            else{
                $this->data['message']= 'English test';
            }
            $data['status']= 1 ; 


            echo json_encode($data,true); 
                    die;
    }

it always goes to en version even if i post ar , if i do var_dump for posted data it gives me false . Please advise how can i sort it

i always get following response

我使用以下代码测试数据发布但发布数据总是空的我试图使用postman测试但是它没有工作，以下是我写的测试代码，但它总是去其他块，我尝试写其他如果，但它不起作用 p>

 类Api_home扩展CI_Controller  {
 function __construct（）{
 parent :: __ construct（）; 
 
 $ this-＆gt; load-＆gt; model（'Api_model'，'api'）; 
 $ this-＆gt; load-  ＆gt; helper（'form'）; 
 $ data = array（
'message'=＆gt;'出错了'，
'状态'=＆gt; 1，
'数据'=＆gt;''  ，
）;  
} 
公共函数test（）{
 
 $ lang = $ this-＆gt; input-＆gt; post ['lang']; 
 if（$ lang ==“ar”）{
 $  this-＆gt; data ['message'] ='阿拉伯语测试'; 
} 
 //其他如果
 // else if if（$ lang ==“en”）
 else {
 $ this-＆gt  ; data ['message'] ='英语测试'; 
} 
 $ data ['status'] = 1;  
 
 
 echo json_encode（$ data，true）;  
 
cn; 
} 
  code>  pre> 
 
 即使我发布了ar，它总是会转到版本，如果我为发布的数据执行var_dump它会给我错误。 请告知我如何对其进行排序 p> 
 
 
我总是得到以下回复 p>

Fortunately I'm working on a CI project atm so it wasn't too much effort to test this.

Firstly, you have used the wrong brackets for $lang = $this->input->post['lang']; so it just isn't happy, but doesn't throw an error, no idea why.

You should change it to:

$lang = $this->input->post('lang'); Note the curved brackets.

Secondly, I'm not sure if it's intentional or not but you actually have 2 different $data variables going on:

$this->data and $data. So echo json_encode($data, true); shows only what it contains, perhaps you meant echo json_encode($this->data, true);

Finally, the code snippet above is missing a final closing curly brace, hopefully it's not missing from the source!

I hope this helps solve your problem =)

try return json_output:

 public function test(){
   $lang= $this->input->post['lang'];
            if($lang=="ar"){
                $message= 'Arabic test';
return parent::json_output(['code' => '1', 'message' => 'Succesful', 'data' => $message]);
            } 
                    //else if 
                   // else if($lang=="en")
            else{
                $message= 'English test';
return parent::json_output(['code' => '2', 'message' => 'Succesful', 'data' => $message]);
            }
            $data['status']= 1 ; 
  echo json_encode($data,true); 
                    die;
    }
