需要帮助代码点火器restclient与节点服务器

Question

I have a rest client in codeigniter and a server side in node. The source link for codeigniter rest client My client side rest controller looks like this

class Welcome extends CI_Controller {

  public function __construct() {
    parent::__construct();
    $this->load->spark('restclient/2.1.0');
    $this->load->library('rest');
    $this->rest->initialize(array('server' => 'http://localhost:3000/'));
  }

 public function post() {
   $param = array(
     'var1'=>1,
     'var2'=>2
   );

  $this->rest->format("application/json");
  $this->rest->post("/", $param);
  var_dump($this->rest->get("/"));
 }
}

And on the server side I have

var express = require('express');
var bodyParser = require("body-parser");
var app = express();
var port = 3000;

app.use(bodyParser.urlencoded({ extended: false }));

app.post("/", function (req, res) {
  var query1 = req.body.var1;
  var query2 = req.body.var2;

 res.json({result: parseInt(query1) + parseInt(query2)});
});
app.listen(port);

but when I am requestion localhost/welcome/post I am getting the resposne

string(14) "Cannot GET // " 

Where am I going wrong?

Answer 1

change the post function in the CI controller to

 public function post() {
   $param = array(
     'var1'=>1,
     'var2'=>2
   );

  $this->rest->format("application/json");
  //since the server url is allready mentioned as http://localhost:3000/
  // no need to mentin "/" again
  // response should be handled by a variable
  $response = $this->rest->post("", $param);
  var_dump($response);
}
