05-若依使用AJ-captcha验证

准备资料:

若依版本 : ruoyi-vue 3.8.2 【点我去下载】
aj-captcha版本:1.3.0 【去下源码】
参考:若依官方文档-集成aj-captcha

开始

若依vue版本的验证码用了数学运算,还得手工输入计算结果。看了官方文档,改成了目前比较流行的拖动滑块方式。

1.引入MAVEN依赖

若依官方引入的是1.2.7版本。我选择了目前最常用的1.3.0版本。
在项目中给的 ruoyi-framework\pom.xml 添加依赖


    <dependency>
        <groupId>com.anji-plusgroupId>
        <artifactId>spring-boot-starter-captchaartifactId>
        <version>1.3.0version>
    dependency>

2.修改application.yml,加入aj-captcha配置

在ruoyi-admin模块中的application.yml中添加aj-captcha配置

# 滑块验证码
aj:
   captcha:
      # 缓存类型
      cache-type: redis
      # blockPuzzle 滑块 clickWord 文字点选  default默认两者都实例化
      type: blockPuzzle
      # 右下角显示字
      water-mark: ruoyi.vip
      # 校验滑动拼图允许误差偏移量(默认5像素)
      slip-offset: 5
      # aes加密坐标开启或者禁用(true|false)
      aes-status: true
      # 滑动干扰项(0/1/2)
      interference-options: 2

这只是基础配置,可以参考aj-captcha详细配置选择自己想用的参数。

3.添加实现类指向设置

在ruoyi-admin\src\main\resources\META-INF\services下创建com.anji.captcha.service.CaptchaCacheService文件同时设置文件内容为:

com.ruoyi.framework.web.service.CaptchaRedisService

4.在SecurityConfig中设置aj-captcha匿名访问权限

在 ruoyi-framework/src/main/java/com/ruoyi/framework/config/SecurityConfig.java 文件中configure方法下的httpSecurity添加如下语句:

.antMatchers("/captcha/get", "/captcha/check").anonymous()

5.修改后台实现代码

若依官方文档让修改 ruoyi-admin\com\ruoyi\web\controller\system\SysLoginController.java,如果使用的是我提到的若依版本,不用修改,官方的文档参考的若依版本可能比较低吧。。

大家在修改代码时,切记不要按照文档官方文档直接覆盖,建议使用文本比较工具将代码进行比对后只更新相关内容,这也是开发人员的良好习惯!!!!

修改ruoyi-framework\com\ruoyi\framework\web\service\SysLoginService.java
抽离改动点比较麻烦,大家自行去比对吧。主要改动login方法。

6.资源导入

将aj-captcha 官方提供的demo中的images包整体引入到resources包下。
文章的最上边提供了下载地址,可自行下载。
至此,后端全部修改完毕。

7.修改前端ruoyi-ui

下载官方提供的前端修改代码

在ruoyi-ui目录下的文件不要全部替换到项目中,建议使用beyondcompare比较一下改动内容。

  • ruoyi-ui\package.json
    dependencies 增加
 "crypto-js": "^4.1.1",
  • ruoyi-ui\src\views\login.vue
    删除原来的验证码部分,增加滑块验证码相关代码

  • 其他资源
    将 “集成aj-captcha实现滑块验证码\ruoyi-ui\src\“ 目录下assets、components两个目录直接复制到项目中。

这就够了。api目录下文件用不到。

8.启动

1.建议先启动后端,再启动前端。
2.前后端都增加了依赖,后端需要更新maven依赖,前端更新crypto-js (npm install --save crypto-js)

最终效果如下:
