由 醉酒当歌 提交于 2021-02-16 10:04:07
之前用vue开发了一个单页应用，后台嵌入微信公众号里了,在商品详情收藏该商品地址是 安卓是： http://XXXXX.com.cn/demandDet... ios是： http://XXXXX.com.cn/ 很是好奇为ios 为什么不更新url呢? 多次测试时,当你刷新ios 再次复制链接发现是自己想要的地址; 这是就想到能不能重新构建url呢? 方法一: 在路由导航守卫... router.beforeEach((to, from, next) => { if (to.path !== global.location.pathname) { location.href = location.origin +'/'+ location.hash; } next(); }); 方法二: 个别界面 beforeDestory(){ //清理标识 sessionStroage.replaceItem('flag') }, mounted(){ 　　if( sessionStroage.getItem('flag') === null ){ 　　sessionStroage.setItem('flag',1) 　　location.href = location.origin + +'/'+ location.hash; } } 来源： oschina 链接： https://my

Does Android Jetpack require the use of the Kotlin language?

由 雨燕双飞 提交于 2021-02-16 10:01:58
问题 I can't seem to find a clear answer to this in Google, and all the documentation and samples I've seen for Jetpack seem to refer to and use Kotlin. But do you HAVE to use Kotlin in order to use Jetpack? Or can Jetpack be used with traditional Java programs? I was looking at Kotlin but it adds almost a MB to your app size. And seeing as my entire app is only about 200KB currently, I don't think Kotlin is worth increasing the size of my app by 500%! 回答1: Jetpack is a collection of libraries

由 蓝咒 提交于 2021-02-16 09:15:08
问题 On some android devices (regardless of the OS or Bluetooth version) there is a problem after BLE device connect. The services / characteristics are not up to date. This usually happens when the peripheral changes his services. (while the app was not connected) In this state, it is not possible to use the device. To verify this issue you can discover all characteristics and you see that there are outdated (no more existing) characteristics loaded from cache of the android device. Current

原 使用iperf测试网卡吞吐性能 2018年12月17日 12:38:41 lancewoo 阅读数：138 首先配置待测试的两个网卡的网络地址到同一网段，保证ping对方的IP地址时可以通。两个网卡用网线连接到同一个交换机上，或者直连，交换机交换最大速率不能低于待测试网卡的标称速率。 在两台机器上分别运行命令，哪台做服务端，哪台做客户端都可以： 服务端命令： iperf -s -P 0 -i 1 -p 5001 -w 2M -f k 客户端命令： iperf -c 192.168.1.3 -i 1 -w 2M -t 600 这里服务端设置的IP地址是：192.168.1.3 运行结果： 附 ipef命令行工具： arm Android命令行下载： https://github.com/lancewoo/iperf-android-bin/raw/master/iperf Ubuntu Linux可直接安装： sudo apt install iperf Windows命令行及jpef界面： https://download.csdn.net/download/lancewoo/10845156 来源： oschina 链接： https://my.oschina.net/u/4335973/blog/3572118
