uni-app写的微信小程序如何实现账号密码登录后获取token(而token的有效器一般是30分钟,当页面在操作时token是不会过去,,离开页面第二天登录时token就是过期状态,因为记住了账号密码就不会操作再次登录,但是这样会出现一个token过期的问题,会导致页面无法获取到参数,导致页面无法正确的拿到相关的内容),并且每天的第一次登录后都会直接获取参数而不是耀重新登录
在app.vue中
<script>
import { login, appgetInfo } from '@/src/api/api.js';
export default {
data() {
return {
lastLeaveTime: null,
threshold: 2 * 60 * 60 * 1000, // 2小时
};
},
onLaunch: function() {
console.log('App Launch');
this.autoLogin();
},
onShow: function() {
// 用户重新进入小程序时,检查是否需要自动登录
const currentTime = new Date().getTime();
if (this.lastLeaveTime && (currentTime - this.lastLeaveTime) > this.threshold) {
this.autoLogin();
}
},
onHide: function() {
// 记录用户离开的时间
this.lastLeaveTime = new Date().getTime();
},
methods: {
autoLogin() {
const username = uni.getStorageSync('userName');
const password = uni.getStorageSync('userPassword');
if (username && password) {
this.login(username, password);
}
},
async login(username, password) {
try {
const response = await login(username, password);
if (response.token) {
uni.setStorageSync('token', response.token);
uni.switchTab({
url: '/pages/mine/mine',
});
} else {
throw new Error('用户名或密码不正确');
}
} catch (error) {
console.error('自动登录失败:', error);
uni.showModal({
title: '自动登录失败',
content: error.message || '用户名或密码不正确',
showCancel: false,
});
}
}
}
}
</script>
在/pagesA/login/login.vue登录页
