* 检测升级 使用说明
|
||
* 上传包：
|
||
* 1. 根据传参，先检测传参是否完整，appid appVersion wgtVersion 必传
|
||
* 2. 先从数据库取出所有该平台（从上下文读取平台信息，默认 Andriod）的所有线上发行更新
|
||
* 3. 再从所有线上发行更新中取出版本最大的一版。如果可以，尽量先检测wgt的线上发行版更新
|
||
* 4. 使用上步取出的版本包的版本号 和传参 appVersion、wgtVersion 来检测是否有更新，必须同时大于这两项，否则返回暂无更新
|
||
* 5. 如果库中 wgt包 版本大于传参 appVersion，但是不满足 min_uni_version < appVersion，则不会使用wgt更新，会接着判断库中 app包version 是否大于 appVersion
