APP.vue
在这里插入图片描述

登陆成功后，保存登陆信息

if (res.code === 200) {uni.setStorageSync('loginResult', res)uni.setStorageSync('token', res.token);uni.setStorageSync('login',false);uni.navigateTo({url: "/pages/learning/learning"})
}

退出登录

toLogout: function() {uni.showModal({title: "确认退出登录吗",content: "",confirmText: "确定",showCancel: true,success: (res) => {if (res.confirm) {uni.showLoading();var params = {url: "/user/logout",method: "DELETE",data: {},callBack: res=> {uni.hideLoading()console.log(res)uni.removeStorageSync('loginResult');uni.removeStorageSync('token');uni.removeStorageSync('hadLogin');uni.removeStorageSync('code');uni.removeStorageSync('login');uni.navigateTo({url:"/pages/login/login"})}};http.request(params);}}})	
}
