1. 先到中国网建sms短信通网站注册用户：http://sms.webchinese.cn/user/ 短信验证需要涉及： 用户名 ：用户名为我们刚才注册的用户名 接口安全密钥：我们可以在首页登录后，左边的菜单栏中找到修改短信安全秘钥 手机号码 接收短信的手机号 短信内容 自定义设置String类型
2. 新建一个web项目 a) 导入架包：导入人家提供的类 b) 修改test中的内容即可实现你所要的功能
如果是做短信验证功能 那么就生成6位随机数 然后放到Cookie中 判断验证码时候 就可以获取cookie的值来判断了
Test类:
public class test { //用户名 private static String Uid = "uid"; //接口安全秘钥 private static String Key = "key"; //手机号码，多个号码如13800000000,13800000001,13800000002 private static String smsMob = "13800000000"; //短信内容 private static String smsText = "验证码：8888"; public static void main(String[] args) { HttpClientUtil client = HttpClientUtil.getInstance(); //UTF发送 int result = client.sendMsgUtf8(Uid, Key, smsText, smsMob); if(result>0){ System.out.println("UTF8成功发送条数=="+result); }else{ System.out.println(client.getErrorMsg(result)); } } } HttpClientUtil类 public class HttpClientUtil { private RequestConfig requestConfig = RequestConfig.custom() .setSocketTimeout(15000) .setConnectTimeout(15000) .setConnectionRequestTimeout(15000) .build(); private static HttpClientUtil instance = null; private HttpClientUtil(){} public static HttpClientUtil getInstance(){ if (instance == null) { instance = new HttpClientUtil(); } return instance; } /** * 发送 post请求 * @param httpUrl 地址 */ public String sendHttpPost(String httpUrl) { HttpPost httpPost = new HttpPost(httpUrl);// 创建httpPost return sendHttpPost(httpPost,"utf-8"); } /** * 发送 post请求 * @param httpUrl 地址 * @param maps 参数 * @param type 字符编码格式 */ public String sendHttpPost(String httpUrl, Map<String, String> maps,String type) { HttpPost httpPost = new HttpPost(httpUrl);// 创建httpPost // 创建参数队列 List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); for (String key : maps.keySet()) { nameValuePairs.add(new BasicNameValuePair(key, maps.get(key))); } try { httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs, type)); } catch (Exception e) { e.printStackTrace(); } return sendHttpPost(httpPost,type); } /** * 发送Post请求 * @param httpPost * @return */ private String sendHttpPost(HttpPost httpPost,String reponseType) { CloseableHttpClient httpClient = null; CloseableHttpResponse response = null; HttpEntity entity = null; String responseContent = null; try { // 创建默认的httpClient实例. httpClient = HttpClients.createDefault(); httpPost.setConfig(requestConfig); // 执行请求 response = httpClient.execute(httpPost); entity = response.getEntity(); responseContent = EntityUtils.toString(entity, reponseType); } catch (Exception e) { e.printStackTrace(); } finally { try { // 关闭连接,释放资源 if (response != null) { response.close(); } if (httpClient != null) { httpClient.close(); } } catch (IOException e) { e.printStackTrace(); } } return responseContent; } /** * 发送 get请求 * @param httpUrl */ public String sendHttpGet(String httpUrl) { HttpGet httpGet = new HttpGet(httpUrl);// 创建get请求 return sendHttpGet(httpGet); } /** * 发送 get请求Https * @param httpUrl */ public String sendHttpsGet(String httpUrl) { HttpGet httpGet = new HttpGet(httpUrl);// 创建get请求 return sendHttpsGet(httpGet); } /** * @Title: sendMsgUtf8 * @Description: TODO(发送utf8) * @param: @param Uid * @param: @param Key * @param: @param content * @param: @param mobiles * @param: @return * @date: 2017-3-22 下午5:58:07 * @throws */ @SuppressWarnings({ "rawtypes", "unchecked" }) public int sendMsgUtf8(String Uid,String Key,String content,String mobiles){ Map maps = new HashMap(); maps.put("Uid", Uid); maps.put("Key", Key); maps.put("smsMob", mobiles); maps.put("smsText", content); String result = sendHttpPost("http://utf8.sms.webchinese.cn", maps, "utf-8"); return Integer.parseInt(result); } /** * @Title: sendMsgUtf8 * @Description: TODO(发送utf8) * @param: @param Uid * @param: @param Key * @param: @param content * @param: @param mobiles * @param: @return * @return: int * @author: ly * @date: 2017-3-22 下午5:58:07 * @throws */ @SuppressWarnings({ "rawtypes", "unchecked" }) public int sendMsgGbk(String Uid,String Key,String content,String mobiles){ Map maps = new HashMap(); maps.put("Uid", Uid); maps.put("Key", Key); maps.put("smsMob", mobiles); maps.put("smsText", content); String result = sendHttpPost("http://gbk.sms.webchinese.cn", maps, "gbk"); return Integer.parseInt(result); } /** * 发送Get请求 * @param httpPost * @return */ private String sendHttpGet(HttpGet httpGet) { CloseableHttpClient httpClient = null; CloseableHttpResponse response = null; HttpEntity entity = null; String responseContent = null; try { // 创建默认的httpClient实例. httpClient = HttpClients.createDefault(); httpGet.setConfig(requestConfig); // 执行请求 response = httpClient.execute(httpGet); entity = response.getEntity(); responseContent = EntityUtils.toString(entity, "UTF-8"); } catch (Exception e) { e.printStackTrace(); } finally { try { // 关闭连接,释放资源 if (response != null) { response.close(); } if (httpClient != null) { httpClient.close(); } } catch (IOException e) { e.printStackTrace(); } } return responseContent; } /** * 发送Get请求Https * @param httpPost * @return */ private String sendHttpsGet(HttpGet httpGet) { CloseableHttpClient httpClient = null; CloseableHttpResponse response = null; HttpEntity entity = null; String responseContent = null; try { // 创建默认的httpClient实例.
