百度云 php api接口调用 签名计算

本文介绍百度智能云 计算签名 公共头 调用api接口调用：

post请求示例

require "auth.php"; //此文件是百度云官网提供实例，下方可直接粘贴使用。
// 第一步：生成认证字符串
        $ak = "xxx";  // AccessKeyId
        $sk = "xxx";  // SecretAccessKey

        $method = "POST";
        $host = "bcd.baidubce.com"; //实例域名注册接口 ，实际请看百度云
        $uri = "/v1/domain/registerByTemplate";  //实例域名注册接口，实际请看百度云

        $params = array();

        date_default_timezone_set('UTC');
        $timestamp = new \DateTime();
        $expirationInSeconds = 60;
        $authorization = generateAuthorization($ak, $sk, $method, $host, $uri, $params, $timestamp, $expirationInSeconds); //此方法是百度云官网提供实例，下方可直接粘贴使用。
			
        // 第二步：构造HTTP请求的header、body等信息
        $url = "http://{$host}{$uri}";

        $timeStr = $timestamp->format("Y-m-d\TH:i:s\Z");
        $head = array(
            "Content-Type: application/json",
            "Authorization:{$authorization}",
            "x-bce-date:{$timeStr}",
        );
       $body=[
           "domain" =>"adasddfds.com",	// DomainName
           'years'  =>1,
           "privacy" =>false,
           'templateId'=>'xxx',
           'dns'=>[ "ns1.bdydns.cn", "ns2.bdydns.cn" ]
       ];

        $bodyStr = json_encode($body);

        // 第三步：发送HTTP请求，并输出响应信息。
        $curlp = curl_init();
        //curl_setopt($curlp, CURLOPT_POST, 1);
        curl_setopt($curlp, CURLOPT_URL, $url);
        curl_setopt($curlp, CURLOPT_HTTPHEADER, $head);
        curl_setopt($curlp, CURLOPT_CUSTOMREQUEST, $method);
        curl_setopt($curlp, CURLOPT_POSTFIELDS, $bodyStr);
        curl_setopt($curlp, CURLINFO_HEADER_OUT, 1);
        curl_setopt($curlp, CURLOPT_RETURNTRANSFER, 1);
        $response = curl_exec($curlp);
        $request = curl_getinfo($curlp, CURLINFO_HEADER_OUT);
        $status = curl_getinfo($curlp, CURLINFO_HTTP_CODE);
        curl_close($curlp);
        print("request: {$request}\n");
        print("request body: {$bodyStr}\n");
        print("status: {$status}\n");
        print("response: {$response}\n");

get请求示例

require "auth.php";//此文件是百度云官网提供实例，下方可直接粘贴使用。
// 第一步：生成认证字符串

$uri = "/v1/domain/detail";  //实例域名查询接口，实际请看百度云

$params = array(
	"domain" => "abcsss.com"	// DomainName
);

$expirationInSeconds = 60;
$authorization = generateAuthorization($ak, $sk, $method, $host, $uri, $params, $timestamp, $expirationInSeconds);//此方法是百度云官网提供实例，下方可直接粘贴使用。

// 第二步：构造HTTP请求的header、body等信息
$url = "http://{$host}{$uri}?domain={$params['domain']}";
print_r($url."\n");
$timeStr = $timestamp->format("Y-m-d\TH:i:s\Z");
$head =  array(
    "Content-Type: application/json",
    "Authorization:{$authorization}",
    "x-bce-date:{$timeStr}",
);

$body = array();

$bodyStr = json_encode($body);


// 第三步：发送HTTP请求，并输出响应信息。
$curlp = curl_init();
//curl_setopt($curlp, CURLOPT_POST, 1);
curl_setopt($curlp, CURLOPT_URL, $url);
curl_setopt($curlp, CURLOPT_HTTPHEADER, $head);
curl_setopt($curlp, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($curlp, CURLOPT_POSTFIELDS, $bodyStr);
