PHP Tencent Cloud Server API docking FAQ

With the development of cloud computing technology, more and more companies are beginning to migrate their businesses to cloud servers. As the leading cloud server provider in China, Tencent Cloud's powerful performance and stable services have been favored by the majority of users. This article will introduce some common problems in PHP Tencent Cloud Server API docking, and provide corresponding answers and code examples.

Question 1: How to connect to Tencent Cloud Server API?

Answer: Tencent Cloud provides a wealth of API interfaces for connecting to cloud servers. In PHP, network requests can be made through the curl function library. First, you need to prepare the API key and API key ID, then use the curl function to send an HTTP request and add the corresponding parameters in the request header. The following is a sample code for connecting to Tencent Cloud Server API:

<?php
$secretId = "your_secret_id";
$secretKey = "your_secret_key";
$host = "cvm.tencentcloudapi.com";

$service = "cvm";
$action = "DescribeInstances";
$version = "2017-03-12";
$region = "ap-guangzhou";

$params = array(
    "Action" => $action,
    "Version" => $version,
    "Region" => $region
);

$timestamp = time();
$params["Timestamp"] = $timestamp;
$params["Nonce"] = mt_rand(1000000, 9999999);
$params["SecretId"] = $secretId;
$params["SignatureMethod"] = "HmacSHA256";

ksort($params);

$paramStr = "GET" . $host . "/?" . http_build_query($params);
$signature = base64_encode(hash_hmac("sha256", $paramStr, $secretKey, true));

$url = "https://" . $host . "/?" . http_build_query($params) . "&Signature=" . urlencode($signature);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);

echo $result;
?>

Question 2: How to view the list of Tencent Cloud Server instances?

Answer: Use the DescribeInstances interface to obtain the Tencent Cloud server instance list. The following is a sample code to view the list of Tencent Cloud server instances:

<?php
// 先进行API连接操作

// 设置参数
$params["Offset"] = 0;
$params["Limit"] = 10;

// 发送请求
$result = json_decode($result, true);

// 处理返回结果
if (isset($result["Response"]) && isset($result["Response"]["InstanceSet"])) {
    $instanceSet = $result["Response"]["InstanceSet"];
    foreach ($instanceSet as $instance) {
        echo "实例ID: " . $instance["InstanceId"] . "
";
        echo "实例名称: " . $instance["InstanceName"] . "
";
        echo "实例状态: " . $instance["InstanceState"] . "
";
        echo "公网IP: " . $instance["PublicIpAddresses"][0] . "
";
        echo "私有IP: " . $instance["PrivateIpAddresses"][0] . "
";
        echo "
";
    }
} else {
    echo "获取实例列表失败";
}
?>

Question 3: How to create a Tencent Cloud server instance?

Answer: Use the RunInstances interface to create a Tencent Cloud server instance. The following is a sample code for creating a Tencent Cloud server instance:

<?php
// 先进行API连接操作

// 设置参数
$params["Placement"]["Zone"] = "ap-guangzhou-3";
$params["InstanceType"] = "S1.SMALL1";
$params["ImageId"] = "img-8toqc6s3";
$params["SystemDisk"]["DiskType"] = "CLOUD_BASIC";
$params["SystemDisk"]["DiskSize"] = 50;
$params["InternetAccessible"]["InternetChargeType"] = "TRAFFIC_POSTPAID_BY_HOUR";
$params["InternetAccessible"]["InternetMaxBandwidthOut"] = 1;
$params["InstanceChargeType"] = "PREPAID";
$params["InstanceChargePrepaid"]["Period"] = 1;
$params["InstanceChargePrepaid"]["RenewFlag"] = "NOTIFY_AND_AUTO_RENEW";
$params["InstanceChargePrepaid"]["AutoRenewFlag"] = "NOTIFY_AND_MANUAL_RENEW";
$params["InstanceChargePrepaid"]["RenewFlag"] = "NOTIFY_AND_MANUAL_RENEW";
$params["InstanceChargePrepaid"]["RenewFlag"] = "NOTIFY_AND_MANUAL_RENEW";
$params["InstanceChargePrepaid"]["RenewFlag"] = "NOTIFY_AND_MANUAL_RENEW";

// 发送请求
$result = json_decode($result, true);

// 处理返回结果
if (isset($result["Response"]) && isset($result["Response"]["InstanceId"])) {
    echo "创建实例成功，实例ID：" . $result["Response"]["InstanceId"];
} else {
    echo "创建实例失败";
}
?>
