Snel verbinding maken met mysql en php is heel eenvoudig. Eerst heb je een REST API nodig. U kunt een rest-API maken door elk beschikbaar framework te gebruiken. U kunt uw webservice ook alleen met PHP coderen. Dus hier zal ik het gebruik van elk php-framework laten zien.
Maak dus eerst een bestand aan om uw databaseconstanten op te slaan.
<?php
/**
* Created by PhpStorm.
* User: Belal
* Date: 12/08/16
* Time: 7:58 PM
*/
define('DB_USERNAME', 'root');
define('DB_PASSWORD', '');
define('DB_HOST', 'localhost');
define('DB_NAME', 'iphone');
Maak vervolgens een ander php-bestand om een databaseverbinding te maken.
<?php
class DbConnect
{
private $conn;
function __construct()
{
}
/**
* Establishing database connection
* @return database connection handler
*/
function connect()
{
require_once 'Config.php';
// Connecting to mysql database
$this->conn = new mysqli(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_NAME);
// Check for database connection error
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
// returing connection resource
return $this->conn;
}
}
Nu hebt u nog een bestand nodig om uw databasebewerkingen af te handelen.
<?php
class DbOperation
{
private $conn;
//Constructor
function __construct()
{
require_once dirname(__FILE__) . '/Config.php';
require_once dirname(__FILE__) . '/DbConnect.php';
// opening db connection
$db = new DbConnect();
$this->conn = $db->connect();
}
//Function to create a new user
public function createTeam($name, $memberCount)
{
$stmt = $this->conn->prepare("INSERT INTO team(name, member) values(?, ?)");
$stmt->bind_param("si", $name, $memberCount);
$result = $stmt->execute();
$stmt->close();
if ($result) {
return true;
} else {
return false;
}
}
}
Ten slotte moet u het php-bestand maken dat uw http-verzoek zal behandelen.
<?php
//creating response array
$response = array();
if($_SERVER['REQUEST_METHOD']=='POST'){
//getting values
$teamName = $_POST['name'];
$memberCount = $_POST['member'];
//including the db operation file
require_once '../includes/DbOperation.php';
$db = new DbOperation();
//inserting values
if($db->createTeam($teamName,$memberCount)){
$response['error']=false;
$response['message']='Team added successfully';
}else{
$response['error']=true;
$response['message']='Could not add team';
}
}else{
$response['error']=true;
$response['message']='You are not authorized';
}
echo json_encode($response);
Maak nu gewoon views op uw iOS-applicatie en stuur op buttonclick een verzoek naar uw php-bestand. De code is als volgt.

import UIKit
class ViewController: UIViewController {
//URL to our web service
let URL_SAVE_TEAM = "http://192.168.1.103/MyWebService/api/createteam.php"
//TextFields declarations
@IBOutlet weak var textFieldName: UITextField!
@IBOutlet weak var textFieldMember: UITextField!
//Button action method
@IBAction func buttonSave(sender: UIButton) {
//created NSURL
let requestURL = NSURL(string: URL_SAVE_TEAM)
//creating NSMutableURLRequest
let request = NSMutableURLRequest(URL: requestURL!)
//setting the method to post
request.HTTPMethod = "POST"
//getting values from text fields
let teamName=textFieldName.text
let memberCount = textFieldMember.text
//creating the post parameter by concatenating the keys and values from text field
let postParameters = "name="+teamName!+"&member="+memberCount!;
//adding the parameters to request body
request.HTTPBody = postParameters.dataUsingEncoding(NSUTF8StringEncoding)
//creating a task to send the post request
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){
data, response, error in
if error != nil{
print("error is \(error)")
return;
}
//parsing the response
do {
//converting resonse to NSDictionary
let myJSON = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? NSDictionary
//parsing the json
if let parseJSON = myJSON {
//creating a string
var msg : String!
//getting the json response
msg = parseJSON["message"] as! String?
//printing the response
print(msg)
}
} catch {
print(error)
}
}
//executing the task
task.resume()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
Nog iets dat u moet doen, is de volgende regels toevoegen aan uw Info.plist-bestand, dit is omdat u standaard geen verzoek kunt verzenden naar niet-beveiligde URL's, dus omdat we http hebben, moeten we dit laatste doen.
