将一个ID数组从Swift URLSession传递到PHP以进行SQL查询？

// 构建URL
let url = URL(string: "http://example.com/query.php")!

// 构建请求参数
let ids = [1, 2, 3]
let params = ["ids": ids]

// 构建请求
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject: params, options: [])

// 发送请求
let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("请求失败：\(error)")
    } else if let data = data {
        // 解析响应数据
        let result = try? JSONSerialization.jsonObject(with: data, options: [])
        print("查询结果：\(result)")
    }
}
task.resume()

<?php
// 获取传递的参数
$ids = $_POST['ids'];

// 连接数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 构建SQL查询语句
$sql = "SELECT * FROM table WHERE id IN (" . implode(",", $ids) . ")";

// 执行查询
$result = $conn->query($sql);

// 处理查询结果
if ($result->num_rows > 0) {
    // 构建结果数组
    $data = array();
    while ($row = $result->fetch_assoc()) {
        $data[] = $row;
    }

    // 返回结果数据
    echo json_encode($data);
} else {
    echo "没有查询到结果";
}

// 关闭数据库连接
$conn->close();
