UniApp Login: Store User Data Securely

In UniApp, you can use the uni.setStorageSync(key, data) method to store user information and the uni.getStorageSync(key) method to retrieve the stored user information. Here is a simple example code for storing user information during login.

1. Create a login page with input fields for username and password, as well as a login button.

<template>
  <view>
    <input v-model="username" placeholder="请输入用户名"></input>
    <input v-model="password" placeholder="请输入密码" type="password"></input>
    <button @tap="login">登录</button>
  </view>
</template>

<script>
export default {
  data() {
    return {
      username: '',
      password: '',
    };
  },
  methods: {
    login() {
      // 进行登录验证
      // ...

      // 登录成功后存储用户信息
      const userInfo = {
        username: this.username,
        password: this.password,
        // 其他用户信息...
      };
      uni.setStorageSync('userInfo', userInfo);

      // 跳转到其他页面
      uni.navigateTo({
        url: '/pages/home/home',
      });
    },
  },
};
</script>

1. Use the uni.getStorageSync(key) method to retrieve the stored user information on the page that requires it.

<template>
  <view>
    <text>{{ userInfo.username }}</text>
  </view>
</template>

<script>
export default {
  data() {
    return {
      userInfo: {},
    };
  },
  onLoad() {
    // 获取存储的用户信息
    const userInfo = uni.getStorageSync('userInfo');
    this.userInfo = userInfo;
  },
};
</script>

The code examples above are for demonstration purposes only, and may need to be modified and improved according to specific circumstances in actual application.
