UNIapp实现局域网内在线升级

首先是UNIapp 生成apk

用Hbuilder 进行打包云打包
可以从网站https://www.yunedit.com/reg?goto=cert 使用自有证书，目测比直接使用云证书要快一些。

发布apk 网站

发布内容用IIS发布即可
注意事项中记录如下内容

第一、需要在 iis 的MiMe 中添加apk 的格式，否则无法下载apk 文件到手持机中。添加方式打开MIME 点击添加
分别输入 apk application/vnd.android.package-archive 点击保存即可

第二、发布新的apk 的时候，需要修改应用版本号（往大了修改），同时版本号.json 文件中
newVersionCode对应的值，也要和新的应用版本号相同（方便检测更新） newVersionName 中保存的是当前PDA的版本名称
versionDesc 中可以添加修改的内容 appName 需要添加新发布的apk 名称（用于下载对应的文件）

第三、将对应的文件夹发布在iis中，同时要修改uniapp 中的http.js文件
uni.setStorageSync(‘loadVersion’, ‘http://127.0.0.1:8032/’); 修改内部的url

要在IIS中添加.apk文件的MIME类型，可以按照以下步骤操作：

打开IIS管理器，找到服务器，右键选择“属性”。
在打开的属性窗口中，选择“MIME类型”选项卡。
点击“MIME类型”按钮，打开MIME类型设置窗口。
选择“新建”来添加一个新的MIME类型。
在“扩展名”中填写“.apk”，在“MIME类型”中填写“.apk”的MIME类型“application/vnd.android.package-archive”。
点击“确定”保存设置。
重启IIS服务，以使更改生效。
完成以上步骤后，IIS就能够正确识别和处理.apk文件了

版本号.json中的内容为

{"newVersionCode":223,"newVersionName":"V1.2.0","versionDesc":"升级了部分功能","appName":"android_debug.apk"}
