Uniapp version update hot update and natural update

Ha ha ha Today to record uniapp How to update the version of

First, it is divided into hot renewal and natural renewal

1. A hot update is a forced update Must be updated When the system appears bug when Or when new functions affect the use Use hot update
2. Natural renewal is Optional updates Click the download button to download Click Cancel to discard the update

All right. Next, code it

1. stay App.vue page
   Uninstall onLaunch Inside You can also uninstall methods And then in onLaunch call I use the latter method

methods: {
    
		...mapMutations(['login']),// What is not needed here can be commented out 
			
		/**
		 *  Detection and update implementation of Android applications 
		 */

			var _this = this;
			var version  = 101;
			// console.log(version);
			uni.request({
    
				// Request address , Set up your own server link 
				// url: '*************/index.php/System/version', // This is the full domain name 
				//  You can also write the domain name in the warehouse   Then it calls   In case the domain name is changed back and forth 
				url: _this.baseUrl +'index.php/System/version', 
				method: 'POST',
				data: {
    },
				success: resMz => {
    
					console.log(" Version number information ",resMz.data);
					// Version number returned 
					var server_version = resMz.data.data.version;
					// Time stamp returned  
					var currTimeStamp = resMz.data.data.timestamp;
					// Status code returned  0  It's natural renewal  1 Is forced update 
					var status = resMz.data.data.update_status;
					console.log(" Local version number version= "+ version + ", Update code ="+status + ", Background version number ="+server_version+ ", Time stamp "+ currTimeStamp);
					if (status == 1) {
    
						// Force update   Also known as hot update    The system appears large bug  Must update 
						_this.MustcheckVersionToLoadUpdate(server_version,version);
					} else if (status == 0) {
    
						// Natural renewal 
						uni.getStorage({

								var tipTimeLength = 0;
								console.log( " The time interval ",tipTimeLength);
								let cha = lastTimeStamp + tipTimeLength - currTimeStamp;
								console.log(" Local time stamp =",lastTimeStamp);
								console.log(" Time stamp difference ",cha);
								if (lastTimeStamp + tipTimeLength > currTimeStamp) {
    
									// Don't bother here 
									console.log(' Only when the background timestamp is greater than the local timestamp will it enter ');
								} else {
    
									console.log(' Update immediately ');
									// Reset timestamp 
									_this.setStorageForAppVersion(currTimeStamp);
