你可以将以下代码替换到你的代码中，这样当登录失败且错误为验证码错误时，就会自动刷新验证码：

// 登录方法
login() {
  uni.showLoading({
    title: '登录中...',
    mask: true
  })
  uni.request({
    url: this.$globalVar + '/system/login',
    method: 'POST',
    data: this.form,
    success(res) {
      if (res.data.code === 0) {
        uni.showToast({
          title: "登录成功",
          duration: 2000,
        });
        uni.hideLoading()
        uni.setStorageSync('token', res.data.data.token);
        uni.reLaunch({
          url: '/pages/index/index'
        })
      } else {
        uni.hideLoading()
        if (res.data.msg === '验证码错误') {
          setTimeout(() => {
            this.getCodeUrl()
          }, 2000)
        } else {
          uni.showToast({
            title: res.data.msg,
            icon: 'none',
            duration: 2000
          });
        }
      }
    },
    fail(res) {
      uni.hideLoading()
      uni.showToast({
        title: res.data.msg,
        icon: 'none',
        duration: 2000
      });
    }
  })
},
