StarBlog Blog Development Notes: Frontend Development (6) - Login Page

Preface

The preparation work for frontend development has been completed earlier. Now it's time to start building pages (Copy/Paste)~

Writing pages with ElementUI is straightforward—just follow the official documentation and copy/paste the code to get things done.

Writing Code

Nothing much to say, just code.

Layout

<template>
  <el-form :model="loginForm" :rules="fieldRules" ref="loginForm" label-position="left" label-width="0px"
           class="demo-ruleForm login-container">
    <span class="tool-bar">
    </span>
    <h2 class="title">System Login</h2>
    <el-form-item prop="account">
      <el-input type="text" v-model="loginForm.account" auto-complete="off" placeholder="Account"></el-input>
    </el-form-item>
    <el-form-item prop="password">
      <el-input type="password" v-model="loginForm.password" auto-complete="off" placeholder="Password"></el-input>
    </el-form-item>
    <el-form-item style="width:100%;">
      <el-button type="primary" style="width:48%;" @click.native.prevent="reset">Reset</el-button>
      <el-button type="primary" style="width:48%;" @click.native.prevent="login" :loading="loading">Login</el-button>
    </el-form-item>
  </el-form>
</template>

import Cookies from "js-cookie"

export default {
  name: "Login",
  data() {
    return {
      loading: false,
      loginForm: {
        account: 'admin',
        password: 'admin',
        src: ''
      },
      fieldRules: {
        account: [
          {required: true, message: 'Please enter your account', trigger: 'blur'}
        ],
        password: [
          {required: true, message: 'Please enter your password', trigger: 'blur'}
        ]
      },
      checked: true
    }
  },
  methods: {
    login() {
      this.loading = true
      let userInfo = {
        account: this.loginForm.account, 
        password: this.loginForm.password,
      }
      this.$api.login.login(userInfo).then((res) => {  // Call the login API
        if (res.msg != null) {
          this.$message({message: res.msg, type: 'error'})
        } else {
          Cookies.set('token', res.data.token) // Place token in Cookie
          sessionStorage.setItem('user', userInfo.account) // Save user to local session
          this.$router.push('/')  // Login successful, redirect to homepage
        }
        this.loading = false
      }).catch((res) => {
        this.$message({message: res.message, type: 'error'})
      })
    },
    reset() {
      this.$refs.loginForm.resetFields()
    }
