用户认证
-
用户登录成功后都要进行身份认证,认证通过后才可以预约挂号。
-
认证过程:用户填写基本信息(姓名、证件类型、证件号码和证件照片),提交平台审核
-
用户认证相关接口:
(1)上传证件图片
(2)提交认证
(3)获取认证信息
提交认证
获取认证信息
第01章-阿里云OSS
1、对象存储OSS
用户认证需要上传证件图片,因此我们要做文件服务,为了解决海量数据存储与弹性扩容,项目中我们采用云存储的解决方案:阿里云OSS。
1.1、开通“对象存储OSS”服务
(1)申请阿里云账号
(2)实名认证
(3)开通“对象存储OSS”服务
(4)进入管理控制台
1.2、创建Bucket
为Bucket起一个名字,其余选项默认即可。
注意:项目中涉及身份证照片,读写权限选择默认的“私有”
得到endpoint:创建Bucket后,在概览页面可以获取当前Bucket的endpoint值,这个值后面编程的时候会用到
1.3、上传测试文件
创建一个文件夹,上传一个文件
2、使用RAM子用户
2.1、进入子用户管理页面
2.2、添加用户
2.3、获取子用户Id和key
AccessKeyId, AccessKeySecret
2.4、设置用户权限
添加权限:AliyunOSSFullAccess
3、使用SDK
在对象存储首页的右侧,可以找到帮助文档的入口
第02章-用户认证
1、新建云服务模块
1.1、创建模块
在service模块下创建子模块service-yun
1.2、添加依赖
在service-yun中引入依赖
<dependencies>
<!-- 阿里云oss依赖 -->
<dependency>
<groupId>com.aliyun.oss</groupId>
<artifactId>aliyun-sdk-oss</artifactId>
<version>3.15.1</version>
</dependency>
<!--实体-->
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>model</artifactId>
<version>1.0</version>
</dependency>
<!--服务通用配置-->
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>service-util</artifactId>
<version>1.0</version>
</dependency>
<!--时间日期工具-->
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
</dependency>
<!--自定义安全模块-->
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>spring-security</artifactId>
<version>1.0</version>
</dependency>
<!-- 单元测试 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
1.3、创建配置文件
在server-yun模块中resources目录下创建文件
application.yml
:
spring:
application:
name: service-yun
profiles:
active: dev,redis
application-dev.yml
:
server:
port: 8204
spring:
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
servlet:
multipart:
max-file-size: 10MB
max-request-size: 10MB
logging:
level:
root: info
file:
path: yun
aliyun:
oss: #阿里云 OSS
endpoint: your endpoint
key-id: your accessKeyId
key-secret: your accessKeySecret
bucket-name: your bucketname
1.4、创建启动类
创建ServiceYunApplication
package com.atguigu.syt.yun;
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)//取消数据源配置自动读取
@ComponentScan(basePackages = {"com.atguigu"})
public class ServiceYunApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceYunApplication.class, args);
}
}
1.5、配置网关
在网关中配置如下内容:
- id: service-yun
predicates: Path=/*/yun/**
uri: lb://service-yun
2、文件上传
2.1、从配置文件读取常量
创建常量读取工具类:OssConstantProperties.java
package com.atguigu.syt.yun.utils;
@Configuration
@ConfigurationProperties(prefix="aliyun.oss") //读取节点
@Data
public class OssConstantProperties {
private String endpoint;
private String keyId;
private String keySecret;
private String bucketName;
}
2.2、Controller
创建controller.front包,创建FrontFileController类
package com.atguigu.syt.yun.controller.front;
@Api(tags = "阿里云文件管理")
@RestController
@RequestMapping("/front/yun/file")
public class FrontFileController {
@Resource
private FileService fileService;
/**
* 文件上传
*/
@ApiOperation("文件上传")
@ApiImplicitParam(name = "file",value = "上传文件", required = true)
@PostMapping("/auth/upload")
public Result<Map<String, String>> upload(MultipartFile file) {
Map<String, String> map = fileService.upload(file);
return Result.ok(map);
}
}
2.3、Service
接口:FileService
package com.atguigu.syt.oss.service;
public interface FileService {
/**
* 文件上传
* @param file
* @return
*/
Map<String, String> upload(MultipartFile file);
}
实现:FileServiceImpl
参考SDK中的:Java->上传文件->简单上传->流式上传->上传文件流
package com.atguigu.syt.oss.service.impl;
@Service
@Slf4j
public class FileServiceImpl implements FileService {
@Resource
private OssConstantProperties ossConstantProperties;
/**
* 参考SDK中的:Java->上传文件->简单上传->流式上传->上传文件流
* @param file
* @return
*/
@Override
public Map<String, String> upload(MultipartFile file) {
// Endpoint以华东1(杭州)为例,其它Region请按实际情况填写。
String endpoint = ossConstantProperties.getEndpoint();
// 阿里云账号AccessKey拥有所有API的访问权限,风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维,请登录RAM控制台创建RAM用户。
String accessKeyId = ossConstantProperties.getKeyId();
String accessKeySecret = ossConstantProperties.getKeySecret();
// 填写Bucket名称,例如examplebucket。
String bucketName = ossConstantProperties.getBucketName();
// 文件名称
String originalFilename = file.getOriginalFilename();
String dateString = new DateTime().toString("yyyyMMdd");
// 填写Object完整路径,完整路径中不能包含Bucket名称,例如exampledir/exampleobject.txt。
String objectName =
dateString
+ "/" + UUID.randomUUID().toString().replace("-", "")
+ originalFilename.substring(originalFilename.lastIndexOf("."));
// 创建OSSClient实例。
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
try {
InputStream inputStream = file.getInputStream();
// 创建PutObjectRequest对象。
PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, objectName, inputStream);
// 设置该属性可以返回response。如果不设置,则返回的response为空。
putObjectRequest.setProcess("true");
// 创建PutObject请求。
PutObjectResult result = ossClient.putObject(putObjectRequest);
// 如果上传成功,则返回200。
log.info(Integer.toString(result.getResponse().getStatusCode()));
if(result.getResponse().getStatusCode() != 200){
throw new GuiguException(ResultCodeEnum.FAIL);
}
//返回图片路径
//参考SDK中的:Java-> Java授权访问-> 生成以GET方法访问的签名URL
// 设置URL过期时间为1小时,单位:毫秒
Date expiration = new Date(new Date().getTime() + 60 * 60 * 1000);
URL url = ossClient.generatePresignedUrl(bucketName, objectName, expiration);
Map<String, String> map = new HashMap<>();
map.put("previewUrl", url.toString()); //页面中授权预览图片
map.put("url", objectName); //数据库存储
return map;
} catch (OSSException oe) {
System.out.println("Caught an OSSException, which means your request made it to OSS, "
+ "but was rejected with an error response for some reason.");
System.out.println("Error Message:" + oe.getErrorMessage());
System.out.println("Error Code:" + oe.getErrorCode());
System.out.println("Request ID:" + oe.getRequestId());
System.out.println("Host ID:" + oe.getHostId());
throw new GuiguException(ResultCodeEnum.FAIL, oe);
} catch (GuiguException ce) {
System.out.println("Caught an ClientException, which means the client encountered "
+ "a serious internal problem while trying to communicate with OSS, "
+ "such as not being able to access the network.");
System.out.println("Error Message:" + ce.getMessage());
throw new GuiguException(ResultCodeEnum.FAIL, ce);
} catch (IOException e) {
throw new GuiguException(ResultCodeEnum.FAIL, e);
} finally {
if (ossClient != null) {
ossClient.shutdown();
}
}
}
}
3、授权校验
3.1、辅助类
在service-util模块中添加AuthContextHolder.java
package com.atguigu.common.service.utils;
/**
* 授权校验
*/
@Component
public class AuthContextHolder {
@Resource
private RedisTemplate redisTemplate;
/**
* 校验token是否存在并返回UserId
* @param request
*/
public Long checkAuth(HttpServletRequest request){
//从http请求头中获取token
String token = request.getHeader("token");
if(StringUtils.isEmpty(token)) {
throw new GuiguException(ResultCodeEnum.LOGIN_AUTH);
}
Object userIdObj = redisTemplate.opsForValue().get("user:token:" + token);
//数据存入redis时,按照实际的大小分配空间,取出时int能存下,默认使用int类型,int存不下再用long
//我们无法判断redis中存储的是什么类型的id,因此在此做一个转换
Long userId = null;
if(userIdObj instanceof Integer){
userId = ((Integer)userIdObj).longValue();
}else if(userIdObj instanceof Long){
userId = (Long)userIdObj;
}else if(userIdObj instanceof String){
userId = Long.parseLong(userIdObj.toString());
}
if(StringUtils.isEmpty(userId)) {
throw new GuiguException(ResultCodeEnum.LOGIN_AUTH);
}
return userId;
}
}
3.2、修改文件上传controller
添加校验代码
...
public class FrontFileController {
...
@Resource
private AuthContextHolder authContextHolder;
...
public Result<Map<String, String>> upload(MultipartFile file, HttpServletRequest request) {
authContextHolder.checkAuth(request);
...
}
}
3.3、测试文件上传
首先添加全局参数token,然后再进行测试
4、提交认证
4.1、Controller
创建FrontUserInfoController中添加如下方法
package com.atguigu.syt.user.controller.front;
@Api(tags = "用户管理")
@RestController
@RequestMapping("/front/user/userInfo")
public class FrontUserInfoController {
@Resource
private UserInfoService userInfoService;
@Resource
private AuthContextHolder authContextHolder;
@ApiOperation(value = "用户认证")
@ApiImplicitParam(name = "userAuthVo",value = "用户实名认证对象", required = true)
@PostMapping("/auth/userAuth")
public Result userAuth(@RequestBody UserAuthVo userAuthVo, HttpServletRequest request) {
Long userId = authContextHolder.checkAuth(request);
userInfoService.userAuth(userId, userAuthVo);
return Result.ok();
}
}
4.2、Service
接口:UserInfoService
/**
* 保存实名认证信息
* @param userId
* @param userAuthVo
*/
void userAuth(Long userId, UserAuthVo userAuthVo);
实现:UserInfoServiceImpl
@Override
public void userAuth(Long userId, UserAuthVo userAuthVo) {
//设置认证信息
UserInfo userInfo = new UserInfo();
userInfo.setId(userId);
userInfo.setName(userAuthVo.getName());
userInfo.setCertificatesType(userAuthVo.getCertificatesType());
userInfo.setCertificatesNo(userAuthVo.getCertificatesNo());
userInfo.setCertificatesUrl(userAuthVo.getCertificatesUrl());
userInfo.setAuthStatus(AuthStatusEnum.AUTH_RUN.getStatus());
//信息更新
baseMapper.updateById(userInfo);
}
5、获取认证信息
5.1、Controller
在service-user模块的FrontUserInfoController中添加如下方法
@ApiOperation(value = "获取认证信息")
@GetMapping("/auth/getUserInfo")
public Result<UserInfo> getUserInfo(HttpServletRequest request) {
Long userId = authContextHolder.checkAuth(request);
UserInfo userInfo = userInfoService.getUserInfoById(userId);
return Result.ok(userInfo);
}
5.2、Service
主类添加
@EnableFeignClients("com.atguigu.syt")
接口:UserInfoService
/**
* 根据用户id获取用户信息
* @param userId
* @return
*/
UserInfo getUserInfoById(Long userId);
实现:UserInfoServiceImpl
@Override
public UserInfo getUserInfoById(Long userId) {
UserInfo userInfo = baseMapper.selectById(userId);
return this.packUserInfo(userInfo);
}
辅助方法:UserInfoServiceImpl
@Resource
private DictFeignClient dictFeignClient;
/**
* 封装用户状态、认证状态、证件类型信息
* @param userInfo
* @return
*/
private UserInfo packUserInfo(UserInfo userInfo) {
String certificatesTypeString = dictFeignClient.getName(
DictTypeEnum.CERTIFICATES_TYPE.getDictTypeId(),
userInfo.getCertificatesType()
);
userInfo.getParam().put("certificatesTypeString", certificatesTypeString);
userInfo.getParam().put(
"authStatusString", AuthStatusEnum.getStatusNameByStatus(userInfo.getAuthStatus())
);
userInfo.getParam().put(
"statusString", UserStatusEnum.getStatusNameByStatus(userInfo.getStatus())
);
return userInfo;
}
6、显示图片
6.1、Controller
InnerFileController类
package com.atguigu.syt.yun.controller.inner;
@Api(tags = "阿里云文件管理")
@RestController
@RequestMapping("/inner/yun/file")
public class InnerFileController {
@Resource
private FileService fileService;
@ApiOperation(value = "获取图片预览Url")
@ApiImplicitParam(name = "objectName",value = "文件名", required = true)
@GetMapping("/getPreviewUrl")
public String getPreviewUrl(@RequestParam String objectName) {
return fileService.getPreviewUrl(objectName);
}
}
6.2、Service
接口:FileService
/**
* 获取图片url地址
* @param objectName
* @return
*/
String getPreviewUrl(String objectName);
实现:FileServiceImpl
@Override
public String getPreviewUrl(String objectName) {
// Endpoint以华东1(杭州)为例,其它Region请按实际情况填写。
String endpoint = ossConstantProperties.getEndpoint();
// 阿里云账号AccessKey拥有所有API的访问权限,风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维,请登录RAM控制台创建RAM用户。
String accessKeyId = ossConstantProperties.getKeyId();
String accessKeySecret = ossConstantProperties.getKeySecret();
// 填写Bucket名称,例如examplebucket。
String bucketName = ossConstantProperties.getBucketName();
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);
// 设置URL过期时间为1小时,单位:毫秒
Date expiration = new Date(new Date().getTime() + 60 * 60 * 1000);
URL url = ossClient.generatePresignedUrl(bucketName, objectName, expiration);
System.out.println(url.toString());
return url.toString();
}
6.3、创建service-yun-client
6.4、定义FeignClient
接口:
package com.atguigu.syt.yun.client;
@FeignClient(
value = "service-yun",
contextId = "fileFeignClient",
fallback = FileDegradeFeignClient.class
)
public interface FileFeignClient {
@GetMapping("inner/yun/file/getPreviewUrl")
String getPreviewUrl(@RequestParam String objectName);
}
降级:
package com.atguigu.syt.yun.client.impl;
@Component
public class FileDegradeFeignClient implements FileFeignClient {
@Override
public String getPreviewUrl(String objectName) {
return "图片显示失败";
}
}
6.5、service中添加依赖
<dependency>
<groupId>com.atguigu</groupId>
<artifactId>service-yun-client</artifactId>
<version>1.0</version>
</dependency>
6.6、远程调用
UserInfoServiceImpl:
@Resource
private FileFeignClient fileFeignClient;
UserInfoServiceImpl:packUserInfo方法中添加如下代码
String previewUrl = fileFeignClient.getPreviewUrl(userInfo.getCertificatesUrl());
userInfo.getParam().put("previewUrl", previewUrl);
注意:由于是远程调用阿里云服务器,因此配置文件中feignClient的远程超时时间可以设置的稍微长一些,避免个别情况下由于网络原因出现的图片无法加载的情况
7、用户认证前端
7.1、api
创建api/userInfo.js
import request from '@/utils/request'
//引入js-cookie
import cookie from 'js-cookie'
export default {
saveUserAuth(userAuth) {
return request({
url: `/front/user/userInfo/auth/userAuth`,
method: 'post',
data: userAuth,
headers:{token: cookie.get('token')}
})
},
getUserInfo() {
return request({
url: `/front/user/userInfo/auth/getUserInfo`,
method: `get`,
headers:{token: cookie.get('token')}
})
}
}
7.2、页面渲染
pages/user/index.vue文件
资料:资料>实名认证>user
7.3、统一发送请求头
也可以统一发送请求头:删除api/user.js 中对请求头的设置,修改utils/request.js文件如下
//引入js-cookie
import cookie from 'js-cookie'
修改请求拦截器文章来源:https://www.toymoban.com/news/detail-481960.html
// http request 拦截器
service.interceptors.request.use(
config => {
//从cookie中取出token,并且在请求头中携带token
if (cookie.get('token')) {
config.headers['token'] = cookie.get('token')
}
return config
},
err => {
return Promise.reject(err)
})
