PHP调用乐信短信接口实现短信发送

<?php
$apiUrl = "https://api.lexin.cn/sms/v2/single_send";
$appid = "your_appid";
$appkey = "your_appkey";

$mobile = "手机号";
$content = "您的验证码是：123456【您的签名】";

$data = [
    'appid' => $appid,
    'appkey' => $appkey,
    'mobile' => $mobile,
    'content' => $content,
];

$options = [
    'http' => [
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data),
    ],
];

$context = stream_context_create($options);
$result = file_get_contents($apiUrl, false, $context);

if ($result !== false) {
    $response = json_decode($result, true);
    if ($response && $response['code'] == 0) {
        echo "短信发送成功";
    } else {
        echo "短信发送失败：" . $response['message'];
    }
} else {
    echo "请求发送失败";
}
?>
