How to implement the login page in uniapp step by step

Uniapp is a cross-end development tool based on the Vue.js framework. It supports writing one code and can run on multiple platforms such as mini programs, apps, and H5 at the same time. It is favored by many developers. Implementing a login page is an essential step in developing an App. Next, this article will introduce in detail how to use Uniapp to implement a simple login page in a step-by-step manner.

1. Create a Uniapp project

Download the latest version of HBuilderX from the official website. After the installation is complete, open HBuilderX, click New Project, select the Uniapp template, and then choose to create a new project.

2. Page layout

According to the requirements, we need to implement a login page that includes mobile phone number and password input boxes and login buttons. During the process of creating a new project, Uniapp creates a page named "index" by default, and we can layout it on this page.

First, we need to write a piece of HTML code in the "index" page to create the basic framework of the login page. As shown below:

<template>
  <view class="login">
    <view class="login-input">
      <input type="number" placeholder="请输入手机号" />
    </view>
    <view class="login-input">
      <input type="password" placeholder="请输入密码" />
    </view>
    <view class="login-btn" @click="login">
      登录
    </view>
  </view>
</template>

3. Page style

Next, add style code to the template to style each element on the page. As shown below:

<style>
  .login {
    margin: 0 auto;
    margin-top: 60px;
    width: 80%;
  }
  .login-input {
    border-bottom: 1px solid #ccc;
    padding: 10px 0;
  }
  input {
    width: 100%;
    border: none;
    font-size: 16px;
    height: 40px;
  }
  .login-btn {
    background-color: #007aff;
    color: #fff;
    font-size: 18px;
    padding: 10px;
    text-align: center;
    margin-top: 20px;
    border-radius: 5px;
  }
</style>

4. Implement login logic

Next, we need to implement login logic, that is, when clicking the login button, send a request to the backend interface, verify the user's identity, and Return the corresponding page based on the verification results.

First, in the
