使用Mob进行短信验证码发送

首先，很多第三方短信验证码都可以，为什么我要选择mob的呢？
因为mob的短信验证码是完全免费
mob的官网:http://wiki.mob.com/

MOB支持IOS，Android，Unity3d，Cocos2d-X的集成，
那Java怎么用呢？
其实MOB开发文档中有详细的介绍。
使用MOB不需要导入任何依赖，只需要把接口文档Java语言的代码拷贝下来
主要有两个方法：
1.requestData()这个是发送验证请求的方法

/**
     * 发起https 请求
     * @param address
     * @param params
     * @return
     */
    public  static String requestData(String address ,String params){

        HttpURLConnection conn = null;
        try {
            // Create a trust manager that does not validate certificate chains
            TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager(){
                public X509Certificate[] getAcceptedIssuers(){return null;}
                public void checkClientTrusted(X509Certificate[] certs, String authType){}
                public void checkServerTrusted(X509Certificate[] certs, String authType){}
            }};

            // Install the all-trusting trust manager
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, trustAllCerts, new SecureRandom());

            //ip host verify
            HostnameVerifier hv = new HostnameVerifier() {
                public boolean verify(String urlHostName, SSLSession session) {
                    return urlHostName.equals(session.getPeerHost());
                }
            };

            //set ip host verify
            HttpsURLConnection.setDefaultHostnameVerifier(hv);

            HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

            URL url = new URL(address);
            conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("POST");// POST
            conn.setConnectTimeout(3000);
            conn.setReadTimeout(3000);
            // set params ;post params
            if (params!=null) {
                conn.setDoOutput(true);
                DataOutputStream out = new DataOutputStream(conn.getOutputStream());
                out.write(params.getBytes(Charset.forName("UTF-8")));
                out.flush();
                out.close();
            }
            conn.connect();
            //get result
            if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {
                String result = parsRtn(conn.getInputStream());
                return result;
            } else {
                System.out.println(conn.getResponseCode() + " "+ conn.getResponseMessage());
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (conn != null) {
                conn.disconnect();
            }
        }
        return null;
    }

返回的result中有返回值和状态描述

/**
     * 获取返回数据
     * @param is
     * @return
     * @throws IOException
     */
    private static String parsRtn(InputStream is) throws IOException {

        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuffer buffer = new StringBuffer();
        String line = null;
        boolean first = true;
        while ((line = reader.readLine()) != null) {
            if(first){
                first = false;
            }else{
                buffer.append("\n");
            }
            buffer.append(line);
        }
        return buffer.toString();
    }

也是直接拷过来，这两个方法我都写成静态static了，方便调用

发送请求

String result=方法所在类.requestData(verifyUrl,params);

静态方法直接通过类.方法来调用
在官方的文档中
verifyUrl是https://webapi.sms.mob.com/sms/verify,请求的 URL这个是固定的
params包括了以下参数
