106接口的调用(发送短信验证码，可自己加2分钟有效)

getCode方法名，其所属类的类名，都可自定义，方法的参数表和能容不能动，在此getCode及下边的getRandumNum都属于CodeUtils工具类
public static String getCode(String postData, String postUrl){
    try {
        //发送POST请求
        URL url = new URL(postUrl);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        conn.setRequestProperty("Connection", "Keep-Alive");
        conn.setUseCaches(false);
        conn.setDoOutput(true);

        conn.setRequestProperty("Content-Length", "" + postData.length());
        OutputStreamWriter out = new OutputStreamWriter(conn.getOutputStream(), "UTF-8");
        out.write(postData);
        out.flush();
        out.close();

        //获取响应状态
        if (conn.getResponseCode() != HttpURLConnection.HTTP_OK) {
            System.out.println("connect failed!");
            return "";
        }
        //获取响应内容体
        String line, result = "";
        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "utf-8"));
        while ((line = in.readLine()) != null) {
            result += line + "\n";
        }
        in.close();
        return result;
    } catch (IOException e) {
        e.printStackTrace(System.out);
    }
    return "";
}

自动生成随机验证码

public static String getRandomNum(){
    StringBuffer result = new StringBuffer();
    //stringBuilder在jdk1.5以后开始使用速度快，线程不安全，而StringBuffer在jdk1.0开始使用，速度慢，线程安全
    for (int i = 0; i <6 ; i++) {
        result.append(new Random().nextInt(10));
    }
    return result.toString();
}

下面是其方法的调用，数字验证码先存入session，用于用户输入的取出判断，此处可设置2分钟有效，在2分钟后将session的code remove掉即可

getCode方法的调用参数内容根据实际情况决定，第二个参数为短信模板，具体模板参见106jiekou.comhttp://www.106jiekou.com/

request.getSession().setAttribute("code",CodeUtils.getRandomNum());
CodeUtils.getCode("account=106账户&password=106账户登录密码&mobile="+手机号码+"&content=您的验证码是：【"+CodeUtils.getRandomNum()+"】。如需帮助请联系客服。", "http://sms.106jiekou.com/utf8/sms.aspx");
