调用接口实现短信验证

一。首先需要在阿里云，找到短信接口注册accessKeyId，与accessKeySecret 。。注册短信模版，与短信签名，通过之后导入接口提供的两个jar，aliyun-java-sdk-core-3.3.1.jar，aliyun-java-sdk-dysmsapi-1.0.0.jar

public class SmsUtils {

    /**
     * @param args
     */
    public static void main(String[] args) {
        try {
            SmsUtils smsUtils = new SmsUtils();
            String telphoneString = "13168759270";
            smsUtils.sendSms(telphoneString);
        } catch (ClientException e) {
            e.printStackTrace();
        }

    }
    
    //随机验证码
    private int code;
    public int getCode(){
        return code;
    }
    public void setCode(){
        code = (int)(Math.random()*9999)+1000;  //每次调用生成一次四位数的随机数
    }
    
    //初始化ascClient需要的几个参数
    static final String product = "Dysmsapi";//短信API产品名称（短信产品名固定，无需修改）
    static final String domain = "dysmsapi.aliyuncs.com";//短信API产品域名（接口地址固定，无需修改）
    
    //替换成你的AK
    static final String accessKeyId = "LTAIF7iyP8nt4UtZ";//你的accessKeyId,参考本文档步骤2
    static final String accessKeySecret = "v9HX4yNJAGZoxOclDS96GzFClT926y";//你的 accessKeySecret

    public SendSmsResponse sendSms(String telphone) throws ClientException{
        //设置超时时间

        System.setProperty("sun.net.client.defaultReadTimeout", "10000");

        IClientProfile profile=DefaultProfile.getProfile("cn-hangzhou", accessKeyId, accessKeySecret);
        DefaultProfile.addEndpoint("cn-hangzhou", "cn-hangzhou",product, domain);
        IAcsClient acsClient=new DefaultAcsClient(profile);
        
        //组装请求对象
        SendSmsRequest request=new SendSmsRequest();
        //使用post提交
        request.setMethod(MethodType.POST);
        //待发送的手机号
        request.setPhoneNumbers(telphone);
        //短信签名

        //短信模板ID
        request.setTemplateCode("SMS_137620029");
        //验证码
        SmsUtils sms = new SmsUtils();
        sms.setCode();
        String codetemp = sms.getCode()+"";
        System.out.println("code:        "+codetemp);
        /*
         * 可选:模板中的变量替换JSON串,
         * 如模板内容为"亲爱的${name},您的验证码为${code}"时,
         * 此处的值为{"name":"Tom","code":"1454"}
         *   \  反斜杠为转义字符，使得输出双引号
         */
        request.setTemplateParam("{\"name\":\"Tom\", \"code\":\""+codetemp+"\"}");
        //可选:outId为提供给业务方扩展字段,最终在短信回执消息中将此值带回给调用者
        //request.setOutId("1454");
        SendSmsResponse response=acsClient.getAcsResponse(request);
        System.out.println(response.getCode() +"========="+ response.getMessage());
        if(response.getCode() != null && response.getCode().equals("OK")) {
            //请求成功
            System.out.println("发送成功！");
        }else {
            System.out.println("发送失败！");
