在php中使用curl将json post发送到API

$data = array(
    'name' => 'John Doe',
    'email' => 'johndoe@example.com'
);

$jsonData = json_encode($data);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://api.example.com/endpoint');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($jsonData)
));

$response = curl_exec($ch);

if ($response === false) {
    echo 'cURL error: ' . curl_error($ch);
} else {
    $responseData = json_decode($response, true);
    // 处理响应数据
}

curl_close($ch);
