Java 手機驗證碼生成

List:

1.需求

2.實現

3.總結

……1.需求……

使用者提交訂單申請,需要輸入手機號,驗證二維碼。然後再判斷使用者輸入的手機號是否正確,正確則生成訂單資訊入庫。

……2.實現……

實現的思路是,1.傳送二維碼 2.驗證二維碼和redis中存放的是否一致 3.生成訂單入庫

1.傳送二維碼,其實是Java程式碼生成的隨機數字,再用httpclient請求發簡訊的服務,輸入使用者名稱密碼等引數資訊,第一步就完成了。需要將驗證碼存入redis中,在第二步驗證中用得到。

controller:

//	http://managerapi.cuco.cn/order/getVerificationCode
//	{"memberMobile":"15633296156"}
	//獲取驗證碼--zhouzhou--2017年5月6日14:21:14
	@API(value = "獲取驗證碼")
	@RequestMapping(value = "/v1/order/getVerificationCode", method = RequestMethod.POST)
	public Object getVerificationCode(@RequestBody Order order) {
		ParamVerifyUtils.paramNotNull(order.getMemberMobile(), "獲取驗證碼中手機號沒有填寫");
		System.out.println("手機號為:" + order.getMemberMobile());
		if (!PhoneFormatCheckUtils.isPhoneLegal(order.getMemberMobile())) {
			ResponseUtil.toFailureBody(ServerStatus.SHOW_ERROR, "請填寫真實手機號。");
		}
		Member member = new Member();
		member.setMobile(order.getMemberMobile());

		Member memberinfo = this.memberService.getMemberByMobile(member.getMobile());
		if (memberinfo != null) {
			ExceptionUtil.throwWarn("您已成功提交申請,銷售人員稍後會和您聯絡。");
		}
		String identifyCode = SMSUtils.getFourRandom();
		SMSUtils.sendMessage(member.getMobile(), identifyCode);

		JedisUtils.set("identifyCode" + order.getMemberMobile(), identifyCode, 120);
		System.out.println("生成驗證碼--" + identifyCode);
		return identifyCode;
	}
工具類:

get請求記得utf-8轉碼喲,否則手機會收到一堆小方格格。

public class SMSUtils {

	protected Logger logger = Logger.getLogger(this.getClass());

	public static boolean sendMessage(String mobile, String identifyCode) {
		boolean result = false;
		String userId = "馬賽克";
		String password = "馬賽克";
		String pszMobis = mobile;
		String pszMsg = "正式完成簡訊驗證" + "【" + identifyCode + "】";// +
		String iMobiCount = "1";
		String pszSubPort = "*";
		String MsgId = RandomStringUtils.randomNumeric(19);
		try {
			String url = "是一串URL馬賽克"//
					+ "userId=" + userId//
					+ "&password=" + password//
					+ "&pszMobis=" + pszMobis//
					+ "&pszMsg=" + pszMsg//
					+ "&iMobiCount=" + iMobiCount//
					+ "&pszSubPort=" + pszSubPort//
					+ "&MsgId=" + MsgId;
			// RelyHttpClient.sendGet(url, null, "UTF-8");
			// String responseBody = HttpClientUtils.sendGet(url, null,"UTF-8");
			String responseBody = HttpClientUtils.sendGet(url, null,"UTF-8");

			if (StringUtils.isNotBlank(responseBody)) {
				String sub = responseBody.substring(74, responseBody.lastIndexOf("</string>"));
				System.out.println("擷取返回值=================" + sub);
				if (sub.length() > 15) {// 返回值長度大於15則表示成功
					result = true;
					System.out.println("驗證碼發至{}送成功" + mobile);
				} else {
					System.out.println("驗證碼發至{}失敗{}" + mobile + responseBody);
				}
			}
		} catch (Exception e) {
			System.out.println("驗證碼發至{}異常{}" + mobile + e.getMessage());

		}

		return result;
	}

	/**
	 * 產生4位隨機數(0000-9999)
	 * 
	 * @return 4位隨機數
	 */
	public static String getFourRandom() {
		Random random = new Random();
		String fourRandom = random.nextInt(10000) + "";
		int randLength = fourRandom.length();
		if (randLength < 4) {
			for (int i = 1; i <= 4 - randLength; i++)
				fourRandom = "0" + fourRandom;
		}
		return fourRandom;
	}

2.驗證二維碼和redis中存放的是否一致

@API("提交訂單")
	@RequestMapping(value = "/v1/commit_order/pre_create",method = RequestMethod.POST)
	public Object preCreateOrder(@RequestBody Order order){

		//1.判斷是否為空 
		ParamVerifyUtils.paramNotNull(order, "訂單不能為空");
		ParamVerifyUtils.paramNotNull(order.getMemberName(), "會員姓名不能為空");
		ParamVerifyUtils.paramNotNull(order.getMemberMobile(), "會員手機號不能為空");
		ParamVerifyUtils.paramNotNull(order.getStatus(), "訂單狀態不能為空");
		ParamVerifyUtils.paramNotNull(order.getOrderFrom(), "訂單來源不能為空");
		ParamVerifyUtils.paramNotNull(order.getVerificationCode(), "驗證碼不能為空");
		if (!PhoneFormatCheckUtils.isPhoneLegal(order.getMemberMobile())) {

			ResponseUtil.toFailureBody(ServerStatus.SHOW_ERROR, "請填寫真實手機號。");
		}
		
		String identifyCode = JedisUtils.get("identifyCode" + order.getMemberMobile());
		if (StringUtils.isEmpty(identifyCode) || !identifyCode.equals(order.getVerificationCode())) {
			ResponseUtil.toFailureBody(ServerStatus.SHOW_ERROR, "驗證碼不正確,請重新獲得驗證碼");

		    
		}
		//2.呼叫service插入
		return orderService.createOrder(order);
		
	}


 3.生成訂單入庫

//建立訂單--zhouzhou--2017年5月6日15:21:14
	@Override
	public Order createOrder(Order order) {
//		 會員姓名、會員手機號、訂單狀態(1.待處理)、remark、order_from、訂單編號(年月日+8位隨機數)
		//1.判斷是否為空
		ParamVerifyUtils.paramNotNull(order, "訂單不能為空");
		ParamVerifyUtils.paramNotNull(order.getMemberName(), "會員姓名不能為空");
		ParamVerifyUtils.paramNotNull(order.getMemberMobile(), "會員手機號不能為空");
		ParamVerifyUtils.paramNotNull(order.getStatus(), "訂單狀態不能為空");
		ParamVerifyUtils.paramNotNull(order.getOrderFrom(), "訂單來源不能為空");

		//2.生成訂單編號
		SimpleDateFormat sdf=new SimpleDateFormat("yyyyMMdd");
		Date date =new Date();
		String str_date = sdf.format(date);
		
		StringBuilder str=new StringBuilder();//定義變長字串
		Random random=new Random();
		//隨機生成數字,並新增到字串
		for(int i=0;i<8;i++){
		    str.append(random.nextInt(10));
		}
		//將字串轉換為數字並輸出
		int num=Integer.parseInt(str.toString());
		
		String order_num=str_date+num;
		System.out.println(order_num);
		
		//3.set 訂單編號
		order.setOrderNum(order_num);
		order.setCreated(date);
		//4.插入
		orderMapper.insertSelective(order);
		
		return order;
	}
效果,哦,就是我手機上的簡訊==

……3.總結……

         實現很簡單,就是用了個httpclient請求埠。然後儲存在redis中,方便獲取。提高獲取的效率。多實踐,多總結。
