UniApp implements detailed analysis of user login and authorization
In modern mobile application development, user login and authorization are essential functions. As a cross-platform development framework, UniApp provides a convenient way to implement user login and authorization. This article will explore the details of user login and authorization in UniApp, and attach corresponding code examples.
1. Implementation of the user login function
- Create a login page
The user login function usually requires a login page, which contains the user’s input account number and Password form and login button. In UniApp, you can use the form component provided by the uni-app
component library to create a login page.
<template> <view> <form> <input type="text" v-model="username" placeholder="请输入账号" /> <input type="password" v-model="password" placeholder="请输入密码" /> <button @click="login">登录</button> </form> </view> </template>
- User login interface call
After the user enters the account and password on the login page, this information needs to be sent to the server for verification. You can use the uni.request
method to send an HTTP request and handle it accordingly after the request is successful.
methods: { login() { uni.request({ url: 'https://example.com/login', method: 'POST', data: { username: this.username, password: this.password }, success: (res) => { if (res.statusCode === 200) { // 登录成功,保存用户信息到本地 uni.setStorageSync('userInfo', res.data.userInfo); uni.showToast({ title: '登录成功', icon: 'success' }); // 跳转到首页 uni.switchTab({ url: '/pages/home/index' }); } else { uni.showToast({ title: res.data.message, icon: 'none' }); } }, fail: (err) => { console.error(err); uni.showToast({ title: '登录失败', icon: 'none' }); } }); } }
- Use local cache to save user information
After successful login, user information can be saved to the local cache for use in other pages. UniApp provides uni.setStorageSync
and uni.getStorageSync
methods to implement data storage and reading.
methods: { login() { // ... if (res.statusCode === 200) { // 登录成功,保存用户信息到本地 uni.setStorageSync('userInfo', res.data.userInfo); // ... } // ... } }
2. Implementation of user authorization function
- WeChat Mini Program User Authorization
For UniApp applications based on the WeChat Mini Program platform, user authorization is usually It refers to obtaining the user’s basic information on WeChat, such as nickname, avatar, etc. You can use the uni.getUserInfo
method to request user authorization and obtain user information after obtaining permission.
uni.getUserInfo({ success: (res) => { const userInfo = res.userInfo; uni.setStorageSync('userInfo', userInfo); // ... }, fail: () => { // 授权失败的处理逻辑 } })
- H5 platform user authorization
On the H5 platform, user authorization can be achieved through the native Web API, such as navigator.geolocation
Get geography Location information, navigator.getUserMedia
obtain media device access permissions, etc. UniApp provides the uni.getSetting
method to obtain and set the current user's authorization information.
uni.getSetting({ success: (res) => { if (res.authSetting['scope.userLocation']) { // 用户已授权获取地理位置信息 navigator.geolocation.getCurrentPosition((position) => { const { latitude, longitude } = position.coords; // ... }); } else { // 用户未授权获取地理位置信息 // ... } } })
Through the above code examples, we can see that UniApp provides a series of APIs and components to facilitate user login and authorization functions. Whether it is based on the WeChat mini program platform or the H5 platform, UniApp can provide a unified and convenient implementation approach. Developers only need to understand the interfaces and components provided by UniApp to easily implement user login and authorization functional requirements.
