短信注册和微信登录的实现

短信发送过程,和微信发送过程,大多都是差不多的,改动不大,也没什么好说的,很简单,代码也固定,下面就是我整里的过程

一、阿里云短信服务

帮助文档:

https://help.aliyun.com/product/44282.html?spm=5176.10629532.0.0.38311cbeYzBm73

(1) 准备:开通阿里云短信服务

添加 签名管理与模板管理

选择 国内消息 - 模板管理 - 添加模板

点击 添加模板,进入到添加页面,输入模板信息

点击提交,等待审核,审核通过后可以使用

点击添加签名,进入添加页面,填入相关信息注意:签名要写的有实际意义

点击提交,等待审核,审核通过后可以使

(2) 在pom中引入依赖

<dependencies>
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
    </dependency>
    <dependency>
        <groupId>com.aliyun</groupId>
        <artifactId>aliyun-java-sdk-core</artifactId>
    </dependency>
</dependencies>

(3) 编写controller,根据手机号发送短信

@RestController
@RequestMapping("/edumsm/msm")
@CrossOrigin
public class MsmController {
    @Autowired
    private MsmService msmService;

    //发送短信的方法
    @GetMapping("send/{phone}")
    public R sendMsm(@PathVariable String phone){
        return  msmService.sentByPhone(phone);
    }
}

(4) 在service实现方法

@Service
public class MsmServiceImpl implements MsmService {
    @Autowired
    private RedisTemplate<String,String> redisTemplate;
    @Override
    public R sentByPhone(String phone) {
        //生成随机值,传递给阿里云
        String code = RandomUtil.getSixBitRandom();
        Map<String,Object> param = new HashMap<>();
        param.put("code",code);
        //调用service发送短信的方法
        boolean isSend =send(param,phone);
        if (isSend){
            //发送成功,把发送成功验证码放到redis里面
            //设置有效时间
            redisTemplate.opsForValue().set(phone,code,5, TimeUnit.MINUTES);
            return R.ok();
        }else{
            return R.error().message("短信发送失败");
        }
    }

    //发送短信的方法
    @Override
    public boolean send(Map<String, Object> param, String phone) {
        if(StringUtils.isEmpty(phone)) return false;

        DefaultProfile profile =
                DefaultProfile.getProfile("default", "阿里云的个人key_id", "阿里云的个人密钥");
        IAcsClient client = new DefaultAcsClient(profile);

        //设置相关固定的参数
        CommonRequest request = new CommonRequest();
        //request.setProtocol(ProtocolType.HTTPS);
        request.setMethod(MethodType.POST);
        request.setDomain("dysmsapi.aliyuncs.com");
        request.setVersion("2017-05-25");
        request.setAction("SendSms");

        //设置发送相关的参数
        request.putQueryParameter("PhoneNumbers",phone); //手机号
        request.putQueryParameter("SignName","申请阿里云的签名名称"); 
        request.putQueryParameter("TemplateCode","申请阿里云的模板code"); 
        request.putQueryParameter("TemplateParam", JSONObject.toJSONString(param)); //验证码数据,转换json数据传递
        try {
            //最终发送
            CommonResponse response = client.getCommonResponse(request);
            boolean success = response.getHttpResponse().isSuccess();
            return success;
        }catch(Exception e) {
            e.printStackTrace();
            return false;
        }
    }
}

(5)生成验证码工具类

/**
 * 获取随机数
 */
public class RandomUtil {

	private static final Random random = new Random();

	private static final DecimalFormat fourdf = new DecimalFormat("0000");

	private static final DecimalFormat sixdf = new DecimalFormat("000000");

	public static String getFourBitRandom() {
		return fourdf.format(random.nextInt(10000));
	}

	public static String getSixBitRandom() {
		return sixdf.format(random.nextInt(1000000));
	}

	/**
	 * 给定数组,抽取n个数据
	 * @param list
	 * @param n
	 * @return
	 */
	public static ArrayList getRandom(List list, int n) {
		Random random = new Random();
		HashMap<Object, Object> hashMap = new HashMap<Object, Object>();
		// 生成随机数字并存入HashMap
		for (int i = 0; i < list.size(); i++) {
			int number = random.nextInt(100) + 1;
			hashMap.put(number, i);
		}
		// 从HashMap导入数组
		Object[] robjs = hashMap.values().toArray();
		ArrayList r = new ArrayList();
		// 遍历数组并打印数据
		for (int i = 0; i < n; i++) {
			r.add(list.get((int) robjs[i]));
			System.out.print(list.get((int) robjs[i]) + "\t");
		}
		System.out.print("\n");
		return r;
	}
}

注:以上就是发送验证码的过程,下面为注册过程

1、controller层

@ApiOperation(value = "会员注册")
@PostMapping("register")
public R register(@RequestBody RegisterInfoVo registerInfoVo){
    log.info("注册的用户信息"+registerInfoVo);
    memberService.register(registerInfoVo);
    return R.ok();
}

2、service层

/**
 * 会员注册
 * @param registerInfoVo
 */
@Override
public void register(RegisterInfoVo registerInfoVo) {
    //获取注册信息,进行校验
    String mobile = registerInfoVo.getMobile();
    String nickname = registerInfoVo.getNickname();
    String password = registerInfoVo.getPassword();
    String code = registerInfoVo.getCode();
    //校验参数
    if(StringUtils.isEmpty(mobile) ||
       StringUtils.isEmpty(mobile) ||
       StringUtils.isEmpty(password) ||
       StringUtils.isEmpty(code)) {
        throw new SuperCourseException(ResultCode.ERROR,"注册信息不能为空,请重新输入");
    }
    //校验校验验证码
    //从redis获取发送的验证码
    String redisCode = redisTemplate.opsForValue().get(mobile);
    log.info("redis中的验证码:"+redisCode);
    log.info("用户输入的验证码:"+code);
    if (!code.equals(redisCode)){
        throw new SuperCourseException(ResultCode.ERROR,"验证码不正确!");
    }
    //查询数据库中是否存在相同的手机号码
    QueryWrapper<User> wrapper = new QueryWrapper<>();
    wrapper.eq("mobile",mobile);
    Integer count = baseMapper.selectCount(wrapper);
    if(count > 0) {
        throw new SuperCourseException(ResultCode.ERROR, "手机号码已存在!");
    }
    //添加注册信息到数据库
    User user = new User();
    user.setNickname(nickname);
    user.setMobile(mobile);
    user.setPassword(MD5.encrypt(password));
    user.setAvatar(Avatar.AVATAR);
    System.out.println(user);
    baseMapper.insert(user);
}

二、微信登录的实现

微信登录步骤都是死的,没上面好说的,我也没有申请,要企业相关资料才可以,我是用别人的几个信息,来进行本地式微信登录,只能重定向到本地,因为这个账户的服务器写好,重定向到本地特定的接口,在实际中,步骤也都差不多,只是修改重定向的url

一、准备工作

https://open.weixin.qq.com

1、注册

2、邮箱激活

3、完善开发者资料

4、开发者资质认证

准备营业执照,1-2个工作日审批、300元

5、创建网站应用

提交审核,7个工作日审批

6、熟悉微信登录流程

参考文档:https://open.weixin.qq.com/cgi-bin/showdocument?action=dir_list&t=resource/res_list&verify=1&id=open1419316505&token=e547653f995d8f402704d5cb2945177dc8aa4e7e&lang=zh_CN

二、后端开发

1、添加依赖

 <!--httpclient-->
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
</dependency>
<!--commons-io-->
<dependency>
   <groupId>commons-io</groupId>
   <artifactId>commons-io</artifactId>
</dependency>
<!--gson-->
<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
</dependency>

1、添加配置

application.properties添加相关配置信息

# 微信开放平台 appid
wx.open.app_id=你的appid
# 微信开放平台 appsecret
wx.open.app_secret=你的appsecret
# 微信开放平台 重定向url
wx.open.redirect_url=http://你的服务器名称/api/ucenter/wx/callback

2、创建常量类

创建util包,创建ConstantPropertiesUtil.java常量类

@Component
public class ConstantWxUtils implements InitializingBean {

    @Value("${wx.open.app_id}")
    private String appId;

    @Value("${wx.open.app_secret}")
    private String appSecret;

    @Value("${wx.open.redirect_url}")
    private String redirectUrl;

    public static String WX_OPEN_APP_ID;
    public static String WX_OPEN_APP_SECRET;
    public static String WX_OPEN_REDIRECT_URL;

    @Override
    public void afterPropertiesSet() throws Exception {
        WX_OPEN_APP_ID = appId;
        WX_OPEN_APP_SECRET = appSecret;
        WX_OPEN_REDIRECT_URL = redirectUrl;
    }
}

3、创建controller

@CrossOrigin
@Controller//注意这里没有配置 @RestController
@RequestMapping("/api/ucenter/wx")
public class WxApiController {

    @Autowired
    private UserService userService;
    //1 生成微信扫描二维码
    @GetMapping("login")
    public String getWxCode() {
        //固定地址,后面拼接参数
//        String url = "https://open.weixin.qq.com/" +
//                "connect/qrconnect?appid="+ ConstantWxUtils.WX_OPEN_APP_ID+"&response_type=code";

        // 微信开放平台授权baseUrl  %s相当于?代表占位符
        String baseUrl = "https://open.weixin.qq.com/connect/qrconnect" +
                "?appid=%s" +
                "&redirect_uri=%s" +
                "&response_type=code" +
                "&scope=snsapi_login" +
                "&state=%s" +
                "#wechat_redirect";

        //对redirect_url进行URLEncoder编码
        String redirectUrl = ConstantWxUtils.WX_OPEN_REDIRECT_URL;
        try {
            redirectUrl = URLEncoder.encode(redirectUrl, "utf-8");
        }catch(Exception e) {
        }

        //设置%s里面值
        String url = String.format(
                baseUrl,
                ConstantWxUtils.WX_OPEN_APP_ID,
                redirectUrl,
                "superCourse"
        );

        //重定向到请求微信地址里面
        return "redirect:"+url;
    }

    @GetMapping("callback")
    public String callback(String code, String state) {
        try {
            //1 获取code值,临时票据,类似于验证码
            //2 拿着code请求 微信固定的地址,得到两个值 accsess_token 和 openid
            String baseAccessTokenUrl = "https://api.weixin.qq.com/sns/oauth2/access_token" +
                    "?appid=%s" +
                    "&secret=%s" +
                    "&code=%s" +
                    "&grant_type=authorization_code";
            //拼接三个参数 :id  秘钥 和 code值
            String accessTokenUrl = String.format(
                    baseAccessTokenUrl,
                    ConstantWxUtils.WX_OPEN_APP_ID,
                    ConstantWxUtils.WX_OPEN_APP_SECRET,
                    code
            );
            //请求这个拼接好的地址,得到返回两个值 accsess_token 和 openid
            //使用httpclient发送请求,得到返回结果
            String accessTokenInfo = HttpClientUtils.get(accessTokenUrl);

            //从accessTokenInfo字符串获取出来两个值 accsess_token 和 openid
            //把accessTokenInfo字符串转换map集合,根据map里面key获取对应值
            //使用json转换工具 Gson
            Gson gson = new Gson();
            HashMap mapAccessToken = gson.fromJson(accessTokenInfo, HashMap.class);
            String access_token = (String)mapAccessToken.get("access_token");
            String openid = (String)mapAccessToken.get("openid");

            //把扫描人信息添加数据库里面
            //判断数据表里面是否存在相同微信信息,根据openid判断
            User user = UserService.getUserByOpenId(openid);
            if(user == null) {//user是空,表没有相同微信数据,进行添加

                //3 拿着得到accsess_token 和 openid,再去请求微信提供固定的地址,获取到扫描人信息
                //访问微信的资源服务器,获取用户信息
                String baseUserInfoUrl = "https://api.weixin.qq.com/sns/userinfo" +
                        "?access_token=%s" +
                        "&openid=%s";
                //拼接两个参数
                String userInfoUrl = String.format(
                        baseUserInfoUrl,
                        access_token,
                        openid
                );
                //发送请求
                String userInfo = HttpClientUtils.get(userInfoUrl);
                //获取返回userinfo字符串扫描人信息
                HashMap userInfoMap = gson.fromJson(userInfo, HashMap.class);
                String nickname = (String)userInfoMap.get("nickname");//昵称
                String headimgurl = (String)userInfoMap.get("headimgurl");//头像

                user = new UcenterMember();
                user.setOpenid(openid);
                user.setNickname(nickname);
                user.setAvatar(headimgurl);
                userService.save(member);
            }
            //使用jwt根据member对象生成token字符串
            String jwtToken = JwtUtils.getJwtToken(user.getId(), user.getNickname());
            //最后:返回首页面,通过路径传递token字符串
            return "redirect:http://localhost:3000?token="+jwtToken;
        }catch(Exception e) {
            throw new SuperCourseException(ResultCode.ERROR,"登录失败");
        }
    }
}

4、业务层

业务接口:UserService.java

@Override
public User getUserByOpenId(String openid) {
    QueryWrapper<UcenterMember> queryWrapper = new QueryWrapper<>();
    queryWrapper.eq("openid", openid);
    UcenterMember member = baseMapper.selectOne(queryWrapper);
    return member;
}
