尝试使用PHP从swift发送post请求

import Foundation

func sendPostRequest() {
    let url = URL(string: "http://example.com/api")!
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    
    let postData = "key1=value1&key2=value2"
    request.httpBody = postData.data(using: .utf8)
    
    let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
        if let error = error {
            print("Error: \(error)")
            return
        }
        
        if let data = data {
            let responseString = String(data: data, encoding: .utf8)
            print("Response: \(responseString ?? "")")
        }
    }
    
    task.resume()
}

<?php
$key1 = $_POST['key1'];
$key2 = $_POST['key2'];

// 处理接收到的数据
// ...

// 返回响应
$response = array('status' => 'success', 'message' => 'Post request received');
echo json_encode($response);
?>
