（十九）VueCli3.0全栈——登录页

1、client/src/views下新建login.vue文件

<template>
  <div class="login">
    <section class="form_container">
      <div class="manage_tip">
        <span class="title">在线后台管理系统</span>
        <el-form
          :model="loginUser"
          :rules="rules"
          ref="loginForm"
          label-width="60px"
          class="loginForm"
        >
          <el-form-item label="邮箱" prop="email">
            <el-input v-model="loginUser.email" placeholder="请输入email"></el-input>
          </el-form-item>

          <el-form-item label="密码" prop="password">
            <el-input type="password" v-model="loginUser.password" placeholder="请输入密码"></el-input>
          </el-form-item>

          <el-form-item>
            <el-button type="primary" class="submit_btn" @click="submitForm('loginForm')">登录</el-button>
          </el-form-item>
          <div class="tiparea">
            <p>
              还没有账号？现在
              <router-link to="/register">注册</router-link>
            </p>
          </div>
        </el-form>
      </div>
    </section>
  </div>
</template>

<script>
export default {
  name: "login",
  components: {},
  data() {

    return {
      loginUser: {
        email: "",
        password: "",
      },
      rules: {
        email: [
          {
            type: "email",
            required: true,
            message: "邮箱格式不正确",
            trigger: "blur"
          }
        ],
        password: [
          {
            required: true,
            message: "密码不能为空",
            trigger: "blur"
          },
          {
            min: 6,
            max: 30,
            message: "长度在6到30之间",
            trigger: "blur"
          }
        ]
      }
    };
  },
  methods: {
    submitForm(formName) {
      this.$refs[formName].validate(valid => {
        if (valid) {
          this.$axios
            .post("/api/users/login", this.loginUser)
            .then(res => {
              console.log(res);
            })
            .catch(err => {
              console.log(err);
            });

          // 登录成功,跳转
          this.$router.push('/index');
        } else {
          console.log("error submit!!");
          return false;
        }
      });
    }
  }
};
</script>

<style scoped>
.login {
  position: relative;
  width: 100%;
  height: 100%;
  background: url(../assets/bg.jpg) no-repeat center center;
  background-size: 100% 100%;
}
.form_container {
  width: 370px;
  height: 210px;
  position: absolute;
  top: 10%;
  left: 34%;
  padding: 25px;
  border-radius: 5px;
  text-align: center;
}

.form_container .manage_tip .title {
  font-family: "Microsoft YaHei";
  font-weight: bold;
  font-style: 26px;
  color: #fff;
}
.loginForm {
  margin-top: 20px;
  background-color: #fff;
  padding: 20px 40px 20px 20px;
  border-radius: 5px;
  box-shadow: 0px 5px 10px #cccc;
}
.submit_btn {
  width: 100%;
}
.tiparea{
    text-align: right;
    font-size: 12px;
    color: #333;
}
.tiparea p a{
    color: #409eff;
}

</style>

2、设置路由

在client/src/router.js里面

• 引入：import Login from './views/Login'

• 设置路径

 {
      path:'/login',
      name:'login',
      component:Login
    }

3、修改login.vue

• 把token进行处理，存储到localstorage里面

submitForm(formName) {
      this.$refs[formName].validate(valid => {
        if (valid) {
          this.$axios
            .post("/api/users/login", this.loginUser)
            .then(res => {
                // token 
                const {token} = res.data;
                // 存储到localstorage
                localStorage.setItem("eleToken",token);

                 // 登录成功,跳转
                this.$router.push('/index');

            })
            .catch(err => {
              console.log(err);
            });

         
        } else {
          console.log("error submit!!");
          return false;
        }
      });
    }

• 测试token

  打开浏览器，进入login页，进入开发者模式，打开localstorage，输入正确的邮箱和密码后点击登录，发现存入localstorage成功。

测试token

下一节会对token进行过期处理。
