登录界面

ruoyi-ui/src/views/login.vue

点击登录按钮进入handleLogin方法

     handleLogin() {
      //验证数据是否合法
      this.$refs.loginForm.validate(valid => {
        if (valid) {
          this.loading = true;
          //如果记住密码被勾选
          if (this.loginForm.rememberMe) {
            //直接在cookie中存入相关信息，过期时间为30天
            Cookies.set("username", this.loginForm.username, { expires: 30 });
            Cookies.set("password", encrypt(this.loginForm.password), { expires: 30 });
            Cookies.set('rememberMe', this.loginForm.rememberMe, { expires: 30 });
          } else {
            Cookies.remove("username");
            Cookies.remove("password");
            Cookies.remove('rememberMe');
          }
          //调用vuex中的action
          this.$store.dispatch("Login", this.loginForm).then(() => {
            //登录成功后，直接访问主界面
            this.$router.push({ path: this.redirect || "/" }).catch(()=>{});
          }).catch(() => {
            this.loading = false;
            //登录失败，重新生成验证码
            if (this.captchaEnabled) {
              this.getCode();
            }
          });
        }
      });
    }

loginForm

data() {
    return {
      codeUrl: "",
      loginForm: {
        username: "admin",
        password: "admin123",

      },
      loading: false,
      // 验证码开关
      captchaEnabled: true,
      // 注册开关
      register: false,
      redirect: undefined
    };
  },

actions中的Login方法

// 登录
    Login({ commit }, userInfo) {
      //将loginForm的值传递过来做赋值
      const username = userInfo.username.trim()
      const password = userInfo.password
      const code = userInfo.code
      const uuid = userInfo.uuid
      return new Promise((resolve, reject) => {
        //调用具体的login方法，对象传到后端
        login(username, password, code, uuid).then(res => {
          //用户登录成功后保存用户的登录状态，
          let data = res.data
          //保存token以及过期时间，调用auth.js中的具体的function给当前cookies存放token以及过期时间的
          //把token存入cookies,调用了auth.js中的setToken
          setToken(data.access_token)
          //触发mutations，把token存入state
          commit('SET_TOKEN', data.access_token)
          setExpiresIn(data.expires_in)
          commit('SET_EXPIRES_IN', data.expires_in)
          resolve()
        }).catch(error => {
          reject(error)
        })
      })
    },
