        . '=' . percentEncode($value);  
    }  
    // 生成用于计算签名的字符串 stringToSign  
    $stringToSign = 'GET&%2F&' . percentencode(substr($canonicalizedQueryString, 1));  
    //echo "<br>".$stringToSign."<br>";  
    // 计算签名，注意accessKeySecret后面要加上字符'&'

$target = "https://dysmsapi.aliyuncs.com/?";  
$dateTimeFormat = 'Y-m-d\TH:i:s\Z'; // ISO8601规范  
$accessKeyId = 'XXXXXXXX';      // 这里填写您的Access Key ID  
$accessKeySecret = 'XXXXXXXXXXXXXXXXX';  // 这里填写您的Access Key Secret  
$ParamString="{\"XXName\":\"test\",\"XXXXType\":\"test\"}";  

$data = array(  
    'AccessKeyId' => $accessKeyId,
    'Action' => 'SendSms',
    'Format' => 'XML', 
    'OutId' => '123', 
    'PhoneNumbers' => '183XXXXXXXX',
    'RegionId' => 'cn-hangzhou',
    'SignName'=>'XXXX电子商务有限公司',
    'SignatureMethod' => 'HMAC-SHA1',
    'SignatureNonce'=> uniqid(),
    'SignatureVersion' => '1.0',
    'TemplateCode' => 'SMS_9705XXXX', 
    'TemplateParam' => $ParamString,
    'Timestamp' => date($dateTimeFormat),
    'Version' => '2017-05-25'
);  
// 计算签名并把签名结果加入请求参数  
$data['Signature'] = computeSignature($data, $accessKeySecret);  
// 发送请求     
    $result = xml_to_array(https_request($target.http_build_query($data)));  
    echo $result['Error']['Code']."--->".$result['Error']['Message']; 
    echo "<br><br>".$target . http_build_query($data);  
?>

用post方式访问只需要改三处：
1、将computeSignature函数内的拼接字符GET改成POST

 // 生成用于计算签名的字符串 stringToSign  
$stringToSign = 'POST&%2F&' . percentencode(substr($canonicalizedQueryString, 1));  

2、将发送http请求的PHP函数https_request改为用POST方式传：

   function https_request($url)  
{  
    $curl = curl_init();
    //设置抓取的url
    curl_setopt($curl, CURLOPT_URL, 'https://dysmsapi.aliyuncs.com');
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);  
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    //设置头文件的信息作为数据流输出
    curl_setopt($curl, CURLOPT_HEADER, 1);
    //设置获取的信息以文件流的形式返回，而不是直接输出。
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    //设置post方式提交
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $url);
    $data = curl_exec($curl);  
    if (curl_errno($curl)) {return 'ERROR '.curl_error($curl);}  
    curl_close($curl);  
    return $data;  
}  

3、调用https_request的参数需要调整为POST要传输的值

$result = xml_to_array(https_request(http_build_query($data)));  

DONE！
