[JavaScript-PHP]无刷新Ajax+POST使用阿里云短信平台发送短信

最近在帮一个客户做一个短信提醒，找了半天，发现阿里云的短信平台，价格也很便宜

但是阿里云的短信的php demo太复杂了，看得我一愣一愣的

所以呢，我在百度上找到了一个大神的代码，将核心功能封装成了一个类

我就在这个类之上实现了阿里云的短信发送

首先大佬的代码镇楼。。。忘记作者是谁了，总之向他致敬！

<?php
class Sms {
    // 保存错误信息
    public $error;
    // Access Key ID
    private $accessKeyId = '';
    // Access Access Key Secret
    private $accessKeySecret = '';
    // 签名
    private $signName = '';
    // 模版ID
    private $templateCode = '';
    public function __construct($cofig = array()) {
        $cofig = array (
                'accessKeyId' => 'LTAID9K4VZkvWBab',
                'accessKeySecret' => 'vXyIWjb3QykKgE64cqU9yjjkpUq0N5',
                'signName' => 'L给用户的提醒',
                'templateCode' => 'SMS_126865745'
        );
        // 配置参数
        $this->accessKeyId = $cofig ['accessKeyId'];
        $this->accessKeySecret = $cofig ['accessKeySecret'];
        $this->signName = $cofig ['signName'];
        $this->templateCode = $cofig ['templateCode'];
    }
    private function percentEncode($string) {
        $string = urlencode ( $string );
        $string = preg_replace ( '/+/', '%20', $string );
        $string = preg_replace ( '/*/', '%2A', $string );

    private function computeSignature($parameters, $accessKeySecret) {
        ksort ( $parameters );
        $canonicalizedQueryString = '';
        foreach ( $parameters as $key => $value ) {
            $canonicalizedQueryString .= '&' . $this->percentEncode ( $key ) . '=' . $this->percentEncode ( $value );
        }
        $stringToSign = 'GET&%2F&' . $this->percentencode ( substr ( $canonicalizedQueryString, 1 ) );
        $signature = base64_encode ( hash_hmac ( 'sha1', $stringToSign, $accessKeySecret . '&', true ) );
        return $signature;
    }
    /**

    public function send_verify($mobile, $verify_code) {
        $params = array (   //此处作了修改

        //var_dump($params);die;
        // 计算签名并把签名结果加入请求参数

        $url = 'http://dysmsapi.aliyuncs.com/?' . http_build_query ( $params );
         
        $ch = curl_init ();

        if (isset ( $result ['Code'] )) {
            $this->error = $this->getErrorMessage ( $result ['Code'] );

        return true;
    }

    public function getErrorMessage($status) {
        // 阿里云的短信 乱八七糟的(其实是用的阿里大于)

        $message = array (
                'InvalidDayuStatus.Malformed' => '账户短信开通状态不正确',
                'InvalidSignName.Malformed' => '短信签名不正确或签名状态不正确',
                'InvalidTemplateCode.MalFormed' => '短信模板Code不正确或者模板状态不正确',
                'InvalidRecNum.Malformed' => '目标手机号不正确，单次发送数量不能超过100',
                'InvalidParamString.MalFormed' => '短信模板中变量不是json格式',
                'InvalidParamStringTemplate.Malformed' => '短信模板中变量与模板内容不匹配',
                'InvalidSendSms' => '触发业务流控',
                'InvalidDayu.Malformed' => '变量不能是url，可以将变量固化在模板中'
        );
        if (isset ( $message [$status] )) {
            return $message [$status];
        }
        return $status;
    }
}

大家可以根据自己的信息修改密钥 ID等

接下来就是接收POST的PHP页面

<?php
include("ALiYunMessage_class.php");
if($_SERVER['REQUEST_METHOD'] == 'POST')
{
    if(empty($_POST["phone"]))
    {
        echo "请填写手机号";
        exit();
    }
    else if(empty($_POST["UserName"]))
    {
        echo "请填写用户名";
        exit();
    }
    else
    {
        $phone=$_POST["phone"];
        $UserName=$_POST["UserName"];
        $sms = new Sms();
        $status = $sms->send_verify($phone,$UserName);
        if(!$status)
        {
            echo $sms->error;
            exit();
        }
    }
    echo "发送成功！";
}
?>

在我的实际测试中，我发现我得echo “发送成功”  好像没什么用，发送成功会有一个OK的值

下面就是Ajax进行POST请求的代码

function SentMessage(username,phone)
      {
          var xmlhttp=new XMLHttpRequest();
              xmlhttp.onreadystatechange=function()
              {
                if (xmlhttp.readyState==4 && xmlhttp.status==200)
                {
                    alert(xmlhttp.responseText);
                }
              }
          var data = "UserName="+username+"&phone="+phone;
          xmlhttp.open("POST","bin/SentMessage.php",true);
          xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
          xmlhttp.send(data);
      }

简单来是就是发送POST请求，然后将得到的结果alert出来
