很多小白程序猿再找一些短信验证码接口，为此我写了一个JAVA版的短信验证码接口示例代码，又需要的朋友可以拿走试用。
工具/原料
方法/步骤
1短信发送代码示例//接口地址String url = 'http://IP/端口';//下发时间String mttime = new SimpleDateFormat('yyyyMMddHHmmss').format(new Date());Map param = new HashMap();param.put('name', '用户帐号');param.put('pwd', Tools.MD5('用户密码'+mttime));param.put('content', URLEncoder.encode('【阅信短信验证码】验证码888888，打死也不能告诉别人哦。', 'UTF-8'));param.put('phone', '');param.put('subid', '');param.put('mttime', mttime);HttpTool.sendPost(url, param);
2POST提交方法public static String sendPost(String url, Map params) {Log.i('POST提交：[url='+url+']'+params.toString());URL u = null;HttpURLConnection con = null;// 构建请求参数StringBuffer sb = new StringBuffer();if (params != null) {for (Entry e : params.entrySet()) {sb.append(e.getKey()).append('=').append(e.getValue()).append('&');}sb.substring(0, sb.length() - 1);}// 尝试发送请求try {u = new URL(url);con = (HttpURLConnection) u.openConnection();con.setRequestMethod('POST');con.setConnectTimeout(6000);con.setDoOutput(true);con.setDoInput(true);con.setUseCaches(false);con.setRequestProperty('Content-Type', 'application/x-www-form-urlencoded');OutputStreamWriter osw = new OutputStreamWriter(con.getOutputStream(), 'UTF-8');osw.write(sb.toString());osw.flush();osw.close();} catch (Exception e) {Log.e(e);} finally {if (con != null) {con.disconnect();}}// 读取返回内容StringBuffer buffer = new StringBuffer();try {BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream(), 'UTF-8'));String temp;while ((temp = br.readLine()) != null) {buffer.append(temp).append('\n');}} catch (Exception e) {Log.e(e);}Log.i('POST响应：'+buffer.toString());return buffer.toString();}
3MD5加密方法public static String MD5(String str){MessageDigest md5 = null; try{ md5 = MessageDigest.getInstance('MD5'); }catch (Exception e){ Log.i(e.getMessage()); return ''; } char[] charArray = str.toCharArray(); byte[] byteArray = new byte[charArray.length]; for (int i = 0; i < charArray.length; i++) byteArray[i] = (byte) charArray[i]; byte[] md5Bytes = md5.digest(byteArray); StringBuffer hexValue = new StringBuffer(); for (int i = 0; i < md5Bytes.length; i++){ int val = ((int) md5Bytes[i]) & 0xff; if (val < 16){ hexValue.append('0'); } hexValue.append(Integer.toHexString(val)); } return hexValue.toString(); }复制以上代码就可以实现JAVA版短信验证码接口调用的流程了。
