PHP api rest router issue - php

Question

To test my android application in a more concrete way, and since my company has no API yet, I decided to "create" it in a simplified way for testing purpose (and learning, i'm only an intern).
The Android app uses Retrofit.
Anyway, I followed one tutorial for a "login" method, where I use the "Post" method in android, passing login and password as #field datas, and everything worked fine, I could retrieve the data in my android app and log in (I do not manage security yet, this will be added later when they hire a devOp)
The problem is after that I wanted to create a Router for more complicated urls (like "/model/client/:id/contracts") and now nothing work anymore. I do not use framework, only composer. I end my internship in two days I do not really have time to learn a big thing.
So, here are the classes that were working before I make the router :
/src/Model/client/login.php :
<?php
namespace App\Model\client;
// required headers
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Headers: access');
header('Access-Control-Allow-Methods: POST');
header('Access-Control-Allow-Credentials: true');
header('Content-Type: application/json');
// include database and object files
include_once 'src/config/Database.php';
include_once 'src/Model/client/client.php';
// Instantiate database and connect
$database = new Database();
$db = $database->connect();
// prepare product object
$client = new Client($db);
console.log("Login launched");
// set ID property of record to read
$client->login = isset($_POST['login']) ? $_POST['login'] : die();
$client->password = isset($_POST['password']) ? $_POST['password'] : die();
// read the details of product to be edited
$result = $client->readOne();
$num = $result->rowCount();
//Check if corresponding client
if($num>0){
if($client->city==3){
$client->city = "Valenciennes";
}
$row = $result->fetch(PDO::FETCH_ASSOC);
if($row['city']==3){
$city = "Valenciennes";
} else {$city='randomname';}
$client->id = $row['id'];
$client->login = $row['login'];
$client->raison = $row['raison'];
$client->addr1 = $row['addr1'];
$client->addr2 = $row['addr2'];
$client->city = $city;
$client->telephone = $row['telephone'];
$client->portable = $row['portable'];
$client->fax = $row['fax'];
$client->email = $row['email'];
$client->tva_intra = $row['tva_intra'];
$client->siret = $row['siret'];
$client->gtr = $row['gtr'];
$client->password = $row['password'];
// create array
$logged_client = array(
'id' => $client->id,
'login'=> $client->login,
'raison' => $client->raison,
'addr1' => $client->addr1,
'addr2' => $client->addr2,
'city' => $client->city,
'telephone'=>$client->telephone,
'portable'=>$client->portable,
'fax'=>$client->fax,
'email'=>$client->email,
'tva_intra'=>$client->tva_intra,
'siret'=>$client->siret,
'password'=>$client->password);
// set response code - 200 OK
http_response_code(200);
// make it json format
echo json_encode($logged_client);
}
else {
// set response code - 404 Not found
http_response_code(404);
// tell the user product does not exist
echo json_encode(array("message" => "Client does not exist.".$client->login));
}
?>
The class of the object I need to retrieve (src/Model/client/client):
<?php
class Client{
//db stuff
private $cnx;
private $table_name='client';
//client properties
public $id;
public $login;
public $nom;
public $raison;
public $addr1;
public $addr2;
public $city;
public $telephone;
public $portable;
public $fax;
public $email;
public $tva_intra;
public $siret;
public $gtr;
public $password;
//constructor
public function __construct($db){
$this->cnx = $db;
}
//GetOne ###########################################################################
function readOne(){
$query = 'SELECT * FROM '.$this->table_name.' WHERE login = ? AND password = ?';
// prepare query statement
$stmt = $this->cnx->prepare($query);
// bind id of product to be updated
$stmt->bindParam(1, $this->login);
$stmt->bindParam(2, $this->password);
// execute query
$stmt->execute();
// get retrieved row
return $stmt;
}
}
?>
The database exists, here is the connection and it worked fine :
<?php
class Database {
//DB Params
private $host='localhost';
private $db_name='techcrea';
private $username = 'root';
private $pwd = '';
private $cnx;
//DB Connect
public function connect(){
$this->cnx = null;
try {
$this->cnx = new PDO('mysql:host='.$this->host.';dbname='. $this->db_name, $this->username,$this->pwd);
$this->cnx->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}catch(PDOException $e){
echo 'Connection Error:'.$e->getMessage();
}
return $this->cnx;
}
}
So here are the problems starting : this are the classes I added and now nothing works anymore, I get router exception errors (no matching routes) etc..., not only in my android app that returns an "onfailure" response, but also when i try the url in my navigator :
1 - Index :
<?php
require 'vendor/autoload.php';
$router= new App\Router\Router($_GET['url']);
$router->get('/', function(){
echo "homepage";
});
$router->post('/Model/client/login', function(){
//require_once 'src/Model/client/login.php';
});
$router->get('/Model/client/:id/contrats', function($id){
echo "contrats";
});
$router->run();
2 - Router
<?php
namespace App\Router;
class Router {
private $url;
private $routes =[];
private $namedRoutes= [];
public function __construct($url){
$this->url = $url;
}
public function get($path, $callable, $name =null){
return $this->add($path,$callable,$name,'GET');
}
public function post($path, $callable, $name=null){
return $this->add($path,$callable,$name,'POST');
}
public function patch($path, $callable, $name=null){
return $this->add($path,$callable,$name,'PATCH');
}
public function put($path, $callable, $name=null){
return $this->add($path,$callable,$name,'PUT');
}
public function delete($path, $callable, $name=null){
return $this->add($path,$callable,$name,'DELETE');
}
private function add($path, $callable,$name,$method){
$route = new Route($path, $callable);
$this->routes[$method][]= $route;
if($name){
$this->namedRoutes[$name] = $route;
}
return $route;
}
public function url($name,$params = []){
if(!isset($this->namedRoutes[$name])){
throw new RouterException("no match name route");
}
$this->namedRoutes[$name]->getUrl($params);
}
public function run(){
if(!isset($this->routes[$_SERVER['REQUEST_METHOD']])){
throw new RouterException('request method does not exist');
}
foreach($this->routes[$_SERVER['REQUEST_METHOD']] as $route){
if($route->match($this->url)){
return $route->call();
}
}
throw new RouterException('no matching routes');
}
}
3 - Route
namespace App\Router;
class Route {
private $path;
private $callable;
private $matches = [];
private $params = [];
public function __construct($path, $callable){
$this->path = trim($path,'/');
$this->callable = $callable;
}
public function with($param, $regex){
$this->params[$param] = str_replace('(','(?:', $regex);
return $this;
}
public function match($url){
$url=trim($url, '/');
$path = preg_replace_callback('#:([\w]+)#', [$this, 'paramMatch'], $this->path);
$regex = "#^$path$#i";
if(!preg_match($regex, $url, $matches)){
return false;
}
array_shift($matches);
$this->matches= $matches;
return true;
}
public function call(){
if(is_string($this->callable)){
$params = explode('#', $this->callable);
$controller = "App\\Controller\\".$params[0]."Controller";
$controller = new $controller();
$action = $params[1];
return $controller->$action();
} else {
return call_user_func_array($this->callable, $this->matches);
}}
private function paramMatch($match){
if(isset($this->params[$match[1]])){
return '('.$this->params[$match[1]].')';
}
return '([^/]+)';
}
public function getUrl($params){
$path = $this->path;
foreach($params as $k=>$v){
$path= str_replace(":$k",$v, $path);
}
return $path;
}
}
and the htaccess doc :
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
Thank you very much if you help me
