接uni-app写的微信小程序如何实现账号密码登录后获取token,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(1),

在main.js中

import App from './App'

// #ifndef VUE3
import Vue from 'vue'
import './uni.promisify.adaptor'
Vue.config.productionTip = false
App.mpType = 'app'

const app = new Vue({
  ...App
})
app.$mount()
// #endif

// #ifdef VUE3
import { createSSRApp } from 'vue'
export function createApp() {
  const app = createSSRApp(App)
  return {
    app
  }
}
// #endif

async function checkAndLogin() {
  const token = uni.getStorageSync('token');
  const username = uni.getStorageSync('userName');
  const password = uni.getStorageSync('userPassword');

  if (!token) {
    try {
      const response = await request({
        url: '/login',
        method: 'POST',
        data: { username, password }
      });

      if (response.token) {
        uni.setStorageSync('token', response.token);
      } else {
        throw new Error('用户名或密码不正确');
      }
    } catch (error) {
      uni.showModal({
        title: '登录失败',
        content: error.message || '用户名或密码不正确',
        showCancel: false,
      });
    }
  }
}

// 在 App.vue 或 main.js 中调用 checkAndLogin
async function onLaunch() {
  await checkAndLogin();
}

在pages.json

创建一个空的{
            "path": "pages/login/login",
            "style": {
                "navigationBarTitleText": "登录"
            }
        },

让路径为pages/login/login里面什么内容都没有,这样保证每次进入的第一个页面都是空白页面

"pages": [
		{
			"path": "pages/login/login",
			"style": {
				"navigationBarTitleText": "登录"
			}
		},
		{
			"path": "pages/mine/mine",
			"style": {
				"navigationBarTitleText": "我的"
			}
		},
		{
			"path": "pages/home/home",
			"style": {
				"navigationBarTitleText": "首页"
			}
		},
		{
			"path": "pages/Operation/Operation",
			"style": {
				"navigationBarTitleText": "运维"
			}
		},
		{
			"path": "pages/index/index",
			"style": {
				"navigationBarTitleText": "服务"
			}
		},
		{
			"path" : "pages/shebe/shebe",
			"style" : 
			{
				"navigationBarTitleText" : "设备"
			}
		}
	],
	"globalStyle": {
		"navigationBarTextStyle":"black",
		"navigationBarBackgroundColor": "#fff",
		"navigationBarTitleText": "uni-app",
		"backgroundColor": "#F8F8F8",
		"enablePullDownRefresh": true,

	},
	"uniIdRouter": {},
	"tabBar": {

		"color": "#7A7E83",
		"selectedColor": "#1296db",
		"borderStyle": "black",
		"backgroundColor": "#F8F8F8",
		"list": [

				"text": "首页",
				"iconPath": "static/imgs/imgs55.png",
				"selectedIconPath": "static/imgs/imgs5.png"

			{
				"pagePath": "pages/Operation/Operation",

				"selectedIconPath": "static/imgs/imgs6.png"
			},
			{
				"pagePath": "pages/shebe/shebe",

				"iconPath": "static/imgs/imgs44.png",
				"selectedIconPath": "static/imgs/imgs4.png"
			}
		]
	},"subPackages": true,
	"noParse": [],
	"subPackages": [
		{
				"root": "pagesA/",
				"pages":[
					{
						"path": "login/login",
