如何在PHP中使用fetch() API POST方法获取数据？

// 使用 fetch API 发起 POST 请求
fetch('http://example.com/api/data.php', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json'
    },
    body: JSON.stringify({
        key1: 'value1',
        key2: 'value2'
    })
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));

<?php
// 检查是否收到 POST 请求
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // 获取 JSON 数据
    $json = file_get_contents('php://input');
    $data = json_decode($json, true);

    // 处理数据
    if (isset($data['key1']) && isset($data['key2'])) {
        $response = [
            'status' => 'success',
            'message' => 'Data received successfully',
            'data' => $data
        ];
    } else {
        $response = [
            'status' => 'error',
            'message' => 'Invalid data'
        ];
    }

    // 返回 JSON 响应
    header('Content-Type: application/json');
    echo json_encode($response);
}
?>
