如何使用 swiftui 和 php 在 Xcode 中的个人资料页面上回显用户详细信息

编程问答 2022-05-25

问题描述

我对 PHP 很陌生，不知道如何继续，所以我真的希望有人能帮助我下一步做什么。我有一个成功的用户注册和登录系统，它连接到我的 swiftui 应用程序的不同视图和文本字段。例如，当用户在注册页面上输入详细信息时，这些详细信息将存储在我在 PHPMyAdmin 上使用 MysqL 创建的数据库中。登录页面也是如此，当用户登录时，它会检查数据库并让其进入个人资料页面。但是，现在，我不知道如何回显已登录到我的 Xcode 应用程序的用户名。我知道我需要包含一个 profile.PHP 文件，但我不知道如何开始。我使用的外键是“username”字段，它存在于我的数据库的两个表中：“users”和“profile”，这是我想要回显并显示在我的 Xcode 应用程序上的值。

这些是我的 PHP 文件：

  1. connect.PHP

        resultArray.forEach((result)=>{
        console.log(result);
        let data: StockObject = result['data'];  //  <--Error is hereeee

            console.log("Date: " + data.date +
                " Close: " + data.close +
                " High: " + data.high +
                " Low: " + data.low +
                " Open: " + data.open +
                " Volume: " + data.volume 
            ); 
    });
}
catch(error){
    console.log("Error: " + JSON.stringify(error));
}

  2. 数据库连接.PHP

     <?PHP

 // details to access the database

 define('dbuser','root');
 define('dbpass','reallyStrongPwd123');
 define('dbhost','localhost');
 define('dbname','registration');
 ?>

    }

  3. dboperations.PHP

     <?PHP

class databaseconnect
{
 private $conn;

 // __contruct = will automatically call this function when you create an object from a class

 function __construct()
 {
 }

 // establish the database connection

 function connect()
 {
     // embed the PHP code from the connect.PHP file

     require_once 'connect.PHP';

     // $this calls the object
     // connect to the database

     $this->conn = new MysqLi(dbhost,dbuser,dbpass,dbname);

     // check for connection error

     if (MysqLi_connect_errno()) {
         echo "Connection Failed " . MysqLi_connect_error();
     }

     return $this->conn;
 }

  4. signup.PHP

      <?PHP

  class dboperation
   {
   private $conn;

  // __contruct = will automatically call this function when you create an object from a class

 function __construct()
 {
     // need to access other PHP files
     require_once 'connect.PHP';
     require_once 'databaseconn.PHP' ;

     // open a new db connection
     $db = new databaseconnect();
     $this->conn = $db->connect();
 }


 // user login

 public function userlogin($username,$password)
     {
         $securepass = md5($password);

         $stmt = $this->conn->prepare("SELECT userid FROM users WHERE username = ? AND password = ?");
         $stmt->bind_param("ss",$username,$securepass);
         $stmt->execute();
         $stmt->store_result();
         return $stmt->num_rows > 0;
     }

 // display details in an array

 public function displayuser($username)
     {
         $stmt = $this->conn->prepare("SELECT username,useremail FROM users WHERE username = ?");
         $stmt->bind_param("s",$username);
         $stmt->execute();
         $stmt->bind_result($username,$useremail);
         $stmt->fetch();
         $user = array();
         $user['username'] = $username;
         $user['useremail'] = $useremail;
         return $user;
     }

 // create a new user function

 public function newuser($userid,$password,$useremail)
 {
     echo $username;
     echo $useremail;
     echo $userid;

     $securepass = md5($password);

     $stmt = $this->conn->prepare("INSERT INTO users(userid,username,password,useremail) values (?,?,?)");

             // binding parameters,data types

             $stmt->bind_param("isss",$userid,$securepass,$useremail);
             $result = $stmt->execute();
         if($result === false){
             echo $stmt->error;
         }
             $stmt->close();
             if ($result) {
                 return true;
             } else {

                 return false;
             }

 }


 }

  5. 登录.PHP

     <?PHP

 //include the db operation file
 require_once 'dboperations.PHP' ;

 // create a response array
 $response = array();
 //   print_r($_SERVER);
 if($_SERVER['REQUEST_METHOD'] == 'GET'){

     //something was posted,collect the data from the post variable

     $username = $_GET['username'];
     $password = $_GET['password'];
     $useremail = $_GET['useremail'];
     $userid = rand(000001,999999);

     // new object
 $db = new dboperation();

     //insert the values
     if($db->newuser($userid,$useremail)){
         $response['error']=false;
         $response['message']='account created';
     }else{

         $response['error']=true;
         $response['message']='account was not created';
     }

 }else{
     $response['error']=true;
     $response['message']='other';
 }
 echo json_encode($response);
 ini_set('display_errors',1);
 ini_set('display_startup_errors',1);
 echo error_reporting(E_ALL);

这是我的个人资料页面的快速代码：

<?PHP


//include the db operation file
require_once 'dboperations.PHP' ;

// create a response array
$response = array();

if ($_SERVER['REQUEST_METHOD'] == 'GET') {

 if (isset($_GET['username']) && isset($_GET['password'])) {

     $db = new dboperation();

     if ($db->userlogin($_GET['username'],$_GET['password'])) {
         $response['error'] = false;
         $response['message'] = 'successful login';
         $response['user'] = $db->displayuser($_GET['username']);
     } else {
         $response['error'] = true;
         $response['message'] = 'invalid username or password';
     }

 } else {
     $response['error'] = true;
     $response['message'] = 'parameters are missing';
  }

 } else {
  $response['error'] = true;
  $response['message'] = "Request not allowed";
}

echo json_encode($response);

} }
