 Installation Alamofire

  CocoaPods

   pod 'Alamofire', '~> 5.2'

------------------------------------ 

建立檔案名稱: t7.php (內容同 t5,php)

並儲存到  https://www.mydomain.com/htdocs/t7.php

<?php

   $response = array();

   

   $data = json_decode(file_get_contents('php://input'), true);

   $item1 = $data["item1"];

   $item2 = $data["item2"];

   $item3 = $data["item3"];

   $item4 = $data["item4"];

   require_once ("config.php");

   $conn = mysqli_connect(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_NAME);

   if( !$conn) 

   {

    die("Connection failed: " . mysqli_connect_error());

   }

   else

   {

    $sql = "INSERT INTO mytabelname (name1, name2, name3, member) value ('$item1','$item2','$item3','$item4')";

    if (mysqli_query($conn, $sql)) 

    {

     $response['error']=false;

     $response['message']='mytabelname added successfully';

    }

    else 

    {

     echo "Error: " . $sql . "<br>" . mysqli_error($conn);

    }

    mysqli_close($conn);            

  }

  echo json_encode($response);

?>

------------------------------------

開啟 Postman 測試

. 選擇 POST

  輸入網址 https://www.mydomain.com/htdocs/t7.php

  Body 選擇 raw 和 JSON

  傳送資料填入下列

{

  "item1": "ABC",

  "item2": "DEF",

  "item3": "XYO",

  "item4": "356"

}

. 點選 Send

. 結果

  $postdata = file_get_contents("php://input", 'r');

  $jsondata = json_decode($postdata, true);

  $item1 = $jsondata["item1"];    

  使用上面三行 就可以取得傳入之資料

建立檔案名稱: t7.swift

iOS XCode 12.3 

import Foundation

import UIKit

func PhpJsonTest()

{

 let params: [String: Any] = ["item1": "ABC",

                              "item2": "DEF",

                              "item3": "HIJ",

                              "item4": "889"]

  AF.request( "https://www.mydomain.com/htdocs/t7.php", method: .post,  parameters: params, encoding: JSONEncoding.default)

   .validate()

   .responseData(emptyResponseCodes: [200, 204, 205]) { response in

   

    DPrint( response)

    switch response.result
