[移动开发]uniapp 安卓ios端热更新

1.封装热更新方法??

import {
	httpRequest,
	hostURL
} from '@/utils/httpRequest'
async function getNewVersion( success, fail) {
	let params = {};
	if (uni.getSystemInfoSync().platform == "ios") {
		params = {
			appType: "storeApp",
			client: "ios",
		};
	} else {
		params = {
			appType: "storeApp",
			client: "az",
		};
	}
	var [err, res] = await uni.request({
		url: hostURL + '/data-dist/api/dist/appHotUpdate/version',
		data: params
	});
	if (res && success) {
		success(res.data);
	}
	if (err && fail) {
		fail(err);
	}
}

function update(fileName) {
	let downURL = hostURL + "/upload-app/" + fileName;
	console.log('下载地址', downURL, hostURL);
	//后台显示进度条
	let dtask = plus.downloader.createDownload(
		downURL, {},
		function(d, status) {
			//下载完成
			uni.showModal({
				title: "更新提示",
				content: "新版本已经准备好，是否更新应用？",
				success: (res) => {
					if (res.confirm) {
						install(d, status);
					}
				},
			});
		}
	);
	start(dtask);
};

function start(dtask) {
	try {
		dtask.start(); //开启下载任务
		let prg = 0;
		let showLoading = plus.nativeUI.showWaiting("正在下载");
		dtask.addEventListener("statechanged", function(task, status) {
			switch (task.state) {
				case 1:
					showLoading.setTitle("正在下载");
					break;
				case 2:
					showLoading.setTitle("已连接到服务器");
					break;
				case 3:
					prg = parseInt(
						(parseFloat(task.downloadedSize) /
							parseFloat(task.totalSize)) *
						100
					);
					showLoading.setTitle("  正在下载" + prg + "%  ");
					break;
				case 4:
					plus.nativeUI.closeWaiting();
					break;
			}
		});

	} catch (err) {
		plus.nativeUI.closeWaiting();
		uni.showToast({
			title: "更新失败-03",
			mask: false,
			duration: 1500,
		});
	}
};

function install(d, status) {
	//下载完成
	if (status === 200) {
		plus.runtime.install(d.filename, {
			force: false
		}, function() {
			plus.nativeUI.closeWaiting();
			plus.nativeUI.alert("应用资源更新完成！是否重启应用！", function() {
				plus.runtime.restart();
			});
		}, function(e) {
			plus.nativeUI.closeWaiting();
			console.log("安装wgt文件失败[" + e.code + "]：" + e.message);
			plus.nativeUI.alert("安装wgt文件失败[" + e.code + "]：" + e.message);
		});
	} else {
		uni.showToast({
			title: "下载失败",
			mask: false,
			duration: 1500,
		});
	}
};

function close(version) {
	try {
		console.log( '保存要跳过的版本', version)
	    uni.setStorageSync('skip_version', version);
	} catch (e) {
	    // error
	}
};

function signOut() {
	// #ifdef APP-PLUS
	plus.runtime.quit();
	// #endif
}

export const getUpdate = function(oldversion, back) {
	getNewVersion( function(res) {
		console.log('获取热更新版本信息', res, oldversion, back);
		if (res.succ == 1 && res.result) {
			let result = res.result;
			if(back){
				try {
				    const value = uni.getStorageSync('skip_version');
					console.log( '是否跳过当前版本',value, result.version)
				    if (value && value === result.version) {
				        return;
				    }
				} catch (e) {
					
				}
			}
			if (result.version != oldversion) {
				console.log('有新版本要更新', result);
				result.back = back;
				plus.nativeUI.confirm(result.remark, function(e) {
					if (e.index === 0) {
						update(result.fileName);
					} else if (result.strategy == '强制') {
						signOut();
					} else if (result.strategy == '推荐') {
						close(result.version);
					}
				}, {
					"title": "新版本",
					"buttons": ["立即更新", result.strategy == '强制' ? "退出应用" : "暂不更新"]
				});
			} else if (!back) {
				plus.nativeUI.alert("当前已是最新版本！");
			}
		}else if (!back) {
				plus.nativeUI.alert("当前已是最新版本！");
			}
	});
}

2.调用热更新方法? （放在App.vue onLaunch生命周期中，在未登录之前就调用）

<style lang="scss">
	/* 注意要写在第一行，同时给style标签加入lang="scss"属性 */
	@import "uview-ui/index.scss";
</style>
<script>
	import {getUpdate} from '@/utils/hotUpdate';
	export default {
		onLaunch: function() {
			console.log('App Launch');
			// #ifdef APP-PLUS
			plus.runtime.getProperty(plus.runtime.appid, function(widgetInfo) {
				uni.setStorageSync("当前版本", widgetInfo.version);
				let oldversion = widgetInfo.version;
				console.log("我的版本login", oldversion);
				getUpdate(oldversion, true);
			});
			// #endif
		},
		onShow: function() {
			console.log('App Show')

		},
		onHide: function() {
			console.log('App Hide')
		},
		globalData: {
			test: ''
		},
		methods: {
		},
	}
</script>

再附上后台管理热更新的图片

自己项目中的代码，真实有效!?
