电子应用程序在导出为 Snap 时无法获取 ipaddress

问题描述

我正在尝试为我的小应用程序“OpenSpeedTest-Server”做一个快照，这是一个简单的网络性能评估工具。 它在 Windows、Mac 和 Linux (DEB) 上运行良好。当我在 Snap 中导出相同的内容时，应用程序无法获取客户端设备的 IP 地址。

我尝试了“禁闭”：“经典”，并插入网络观察等，但没有任何效果。

我手动添加了“@davidwinter/electron-forge-maker-snap”DevDependency 并将其导出为实际工作的 snap。

唯一的问题是应用程序无法获取设备 IP 地址。

我的 Electron Forge package.json

解决方法

{
“name”: “@davidwinter/electron-forge-maker-snap”,“config”: {
“name”: “OpenSpeedTest_Server”,“categories”: [
“Utility”
],“stagePackages”: [
“default”,“iproute2”
]
}
},

},"dependencies": {
"cors": "^2.8.5","electron-squirrel-startup": "^1.0.0","express": "^4.17.1","internal-ip": "^6.2.0","tcp-port-used": "^1.0.2"
},

内部IP负责获取ip地址。

https://www.npmjs.com/package/internal-ip 该模块返回由默认网关确定的面向 Internet 的接口的地址。当由于某种原因无法确定地址时，将返回 undefined。 该模块依赖于操作系统工具。在 Linux 和 Android 上，ip 命令必须可用，默认情况下可能不会安装取决于发行版。它通常由 iproute2 包提供。 .v4.sync() 和 .v6.sync() 在浏览器中不受支持，只返回 undefined。

所以我们需要在 stagePackages 中添加 iproute2 以使其在 snap 上工作。
