onLaunch: async function (options) { this.init() //var _this = this; let menuButtonObject = wx.getMenuButtonBoundingClientRect(); const res = await wx.cloud.callFunction({name: 'getServerTime'}); // 使用await等待异步请求结果 console.log('服务器时间：',res.result) const cloudTimeStamp = res.result;// 需要从res中取出result console.log('服务器时间：',cloudTimeStamp) // 获取小程序系统时间戳 const systemTimeStamp = Date.now(); console.log('运行环境系统时间：',systemTimeStamp) // 计算时间戳差值，单位为秒 const diff = Math.abs(cloudTimeStamp - systemTimeStamp) / 1000; console.log('时间差值：',diff) // 如果时间戳差值大于一定值，则认为小程序系统时间被篡改 if (diff > 100) { wx.showToast({ title: '小程序系统时间被篡改，请检查时间设置', icon: 'none', }); return; } wx.getSystemInfo({ success: res => { let statusBarHeight = res.statusBarHeight, navTop = menuButtonObject.top, navHeight = statusBarHeight + menuButtonObject.height + (menuButtonObject.top - statusBarHeight) * 2; this.globalData.navHeight = navHeight; this.globalData.navTop = navTop; this.globalData.windowHeight = res.windowHeight; }, fail(err) { console.log(err); } }) },怎么修改这个函数让diff大于100时，停止运行小程序

你可以在函数的开头部分添加一个判断，如果diff大于100则直接return，代码如下：

onLaunch: async function (options) {
    this.init()
    let menuButtonObject = wx.getMenuButtonBoundingClientRect();
    const res = await wx.cloud.callFunction({name: 'getServerTime'});
    const cloudTimeStamp = res.result;
    const systemTimeStamp = Date.now();
    const diff = Math.abs(cloudTimeStamp - systemTimeStamp) / 1000;
    if (diff > 100) {
        wx.showToast({
            title: '小程序系统时间被篡改，请检查时间设置',
            icon: 'none',
        });
        return; // 添加这行代码
    }
    wx.getSystemInfo({
        success: res => {
            let statusBarHeight = res.statusBarHeight,
                navTop = menuButtonObject.top,
                navHeight = statusBarHeight + menuButtonObject.height + (menuButtonObject.top - statusBarHeight) * 2;
            this.globalData.navHeight = navHeight;
            this.globalData.navTop = navTop;
            this.globalData.windowHeight = res.windowHeight;
        },
        fail(err) {
            console.log(err);
        }
    })
}

当diff大于100时，会弹出一个提示框，并且直接return，停止运行小程序。
