在App.vue页面中的onLaunch方法中编写相关更新代码

onLaunch:function() {
    
    			
    			const updateManager = uni.getUpdateManager();//本API返回全局唯一的版本更新管理器对象： updateManager，用于管理小程序更新。
    			updateManager.onCheckForUpdate((res)=>{//当向小程序后台请求完新版本信息，进行回调方法
    				
    				if(res.hasUpdate){
    					updateManager.onUpdateReady((res) =>{//当新版本下载完成，会进行回调
    						uni.showModal({
    							title: '更新提示',
    							content: '新版本已经准备好，是否重启应用？',
    							success(res) {
    							  if (res.confirm) {
    								// 新的版本已经下载好，调用 applyUpdate 应用新版本并重启
    								updateManager.applyUpdate();
    							  }
    							}
    						});
    					
    					});
    					updateManager.onUpdateFailed((res)=>{
    						// 新的版本下载失败
    						uni.showModal({
    							title: '更新提示',
    							content: '检查到有新版本，但下载失败，请检查网络设置',
    							success(res) {
    								if (res.confirm) {
    									  // 新的版本已经下载好，调用 applyUpdate 应用新版本并重启
    									  updateManager.applyUpdate();
    								}
    							}
    						});
    					});
    				}
    			})
    			
    		},

在开发时如何测试更新功能呢

1.当编写好相关的代码后编译到微信小程序开发者工具中，点击上方编译模式添加相关编译模式

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjMwNzI4Mw_size_16_color_FFFFFF_t_70][]

2.点击添加编译模式后勾选相对应的操作，自己也可以配置相关参数

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjMwNzI4Mw_size_16_color_FFFFFF_t_70 1][]

3.点击确定后页面就会自动检测是否需要更新

这是成功状态下的模式

失败状态下的

百度端：
