5.9 前端登录页

本次实现了项目的登录前端页面实现
使用了vue和axios

<script setup>
import { User, Lock } from "@element-plus/icons-vue";
import { ElMessage } from "element-plus";
import { ref } from "vue";
import { userRegisterService, userLoginService } from "@/api/user.js";
//控制注册与登录表单的显示， 默认显示注册
const isRegister = ref(false);

//用于注册的数据模型
const registerData = ref({
    username: "",
    password: "",
    rePassword: "",
});
//定义函数,清空数据模型的数据1
const clearRegisterData = () => {
    registerData.value = {
        username: "",
        password: "",
        rePassword: "",
    };
};

//自定义确认密码的校验函数
const rePasswordValid = (rule, value, callback) => {
    if (value == null || value === "") {
        return callback(new Error("请再次确认密码"));
    }
    if (registerData.value.password !== value) {
        return callback(new Error("两次输入密码不一致"));
    }
};
//用于注册的表单校验模型
const registerDataRules = ref({
    username: [
        { required: true, message: "请输入用户名", trigger: "blur" },
        { min: 5, max: 16, message: "用户名的长度必须为5~16位", trigger: "blur" },
    ],
    password: [
        { required: true, message: "请输入密码", trigger: "blur" },
        { min: 5, max: 16, message: "密码长度必须为5~16位", trigger: "blur" },
    ],
    rePassword: [{ validator: rePasswordValid, trigger: "blur" }],
});
// 调用后台接口完成注册
const register = async () => {
    let result = await userRegisterService(registerData.value);
    console.log("result :>> ", result);
    if (result.code === 0) {
        alert(result.msg ? result.msg : "注册成功");
    } else {
        alert("注册失败");
    }
};
import { useRouter } from 'vue-router';
import { useTokenStore } from '@/stores/token.js';
const router = useRouter();
const tokenStore = useTokenStore();
// 登录函数
const login = async () => {
    let result = await userLoginService(registerData.value);
    //保存token
    tokenStore.setToken(result.data)

    ElMessage.success('登录成功!')
    router.push('/')
};
</script>
