本节学习目标

通用登录功能开发

新增登录页面

src/views目录下新增login目录，login目录下新增index.vue

<template>
  <div>
    <div>
      <el-form class="login" ref="formRef" :model="user" :rules="rules" label-width="86px">
        <h3>登录</h3>
        <el-form-item label="用户名" prop="email">
          <el-input
            v-model="user.email"
            placeholder="请输入用户名"
            prefix-icon="user"
          ></el-input>
        </el-form-item>
        <el-form-item label="密码" prop="password">
          <el-input
            v-model="user.password"
            type="password"
            placeholder="请输入密码"
            prefix-icon="lock"
          ></el-input>
        </el-form-item>
        <el-form-item label>
          <el-button
            type="primary"
            class="w100p"
            @click="doLogin"
          >登录</el-button>
        </el-form-item>
        <div class="txt-r">
          <router-link to="/register">没有账号？去注册</router-link>
        </div>
      </el-form>
    </div>
  </div>
</template>
<script setup lang="ts">
import { useRouter } from 'vue-router';
import { login } from '@/api';
import { useUserStore } from '@/stores/user';
import { ref, reactive, computed } from 'vue'
import type { User } from '@/types';
const router = useRouter();
const userStore = useUserStore();
const { setUser } = userStore;
const user = reactive<User>({
  email: '',
  password: '',
});

const formRef = ref();

const rules = computed(() => {
  return {
    email: [
      {
        required: true,
        message: '请输入用户名',
        trigger: ["change", "blur"],
      }
    ],
    password: {
      required: true,
      min: 4,
      message: '密码error',
      trigger: ["change", "blur"],
    },
  }
});

function doLogin() {
  formRef.value.validate(async (valid: any) => {
    if (!valid) return;
    try {
    
      const res = await login({ user:user });
      setUser(res.data.user);

      router.push({ name: 'Home' });
    } catch (error) {
    }
  });
}
</script>
<style lang="scss">
.login {
  width: 480px;
  margin: 200px auto 0;
  text-align: center;
}
</style>

新增登录接口

新增登录路由

修改注册页面，实现已有账号？去登录跳转链接

测试，验证
