uni-app sets login restrictions, if you are not logged in, you will jump to the login interface

Foreword:

The login judgment of the uni-app data, you can continue to view it when you log in, and put it on the login interface if you are not logged in.

Specific steps:

1. Encapsulate the cache method: util/auth.js

const TokenKey = 'uni_token';

// 认证令牌
export function getToken() {
	return uni.getStorageSync(TokenKey)
}

export function setToken(token) {
	return uni.setStorageSync(TokenKey, token)
}

export function removeToken() {
	return uni.removeStorageSync(TokenKey)
}

2. Login page, introduce cache method, login successfully and add token

import {setToken} from '../../util/auth';


登录成功以后
setToken('111111')

3. App.vue page plus control method

import {getToken} from './util/auth';
onLaunch: function() {
    //判断是否登录
		let token = getToken()
		if(!token){
			//不存在则跳转至登录页
			uni.reLaunch({
				url: "/pages/login/login"
			})
		}
}
