如何在 Nativescript 中获取 mac 地址和 ip?

问题描述

我想从我的移动 Android 获取 IP 地址.

var context = application.android.context;var wifiMgr = context.getSystemService("wifi");var wifiInfo = wifiMgr.getConnectionInfo();var ip = wifiInfo.getIpAddress();console.log('ip', ip)

结果为:JS: ip -2029999936

但实际上这不是我的IP.

你能问我任何想法吗?

更新:

我关注this.我有这个代码:

第一步.在我的组件中添加以下代码:

import app = require("application");app.android.context;构造函数(){var context = android.content.Context;var wifiManager = app.android.context.getSystemService(context.WIFI_SERVICE);var wInfo = wifiManager.getConnectionInfo();var mac = wInfo.getMacAddress();}

步骤 2.在 AndroidManifest.xml 添加

错误:[ts] 找不到名称android".[2304] 在这一行:var上下文 = android.content.Context;错误 TS1202:定位 ECMAScript 模块时无法使用导入分配.考虑使用 'import * as ns from "mod"'、'import {a} from "mod"'、'import d from "mod"' 或其他模块格式.

解决方案

您应该在 AndroidManifest.xml 中拥有 ACCESS_WIFI_STATE 权限以捕获 IP 地址.

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

那么你所要做的就是，

import * as application from 'tns-core-modules/application';声明var android;const wifiManager = application.android.context.getSystemService(android.content.Context.WIFI_SERVICE);const connectionInfo = wifiManager.getConnectionInfo();const ip = android.text.format.Formatter.formatIpAddress(connectionInfo.getIpAddress());

declare var android; 是为了避免访问原生api时出现TS错误.另一种方法是安装 tns-platform-declarations 插件并将声明文件指向 references.d.ts.

关于 Mac 地址，因为 Android6.0

为了向用户提供更好的数据保护，从本版本开始，Android 移除了使用 Wi-Fi 和蓝牙 API 的应用对设备本地硬件标识符的编程访问.WifiInfo.getMacAddress() 和 BluetoothAdapter.getAddress() 方法现在返回一个常量值 02:00:00:00:00:00.

所以它似乎没有得到官方支持.

I want to get IP address from my mobile Android.

var context = application.android.context;
var wifiMgr = context.getSystemService("wifi");
var wifiInfo = wifiMgr.getConnectionInfo();
var ip = wifiInfo.getIpAddress();
console.log('ip', ip)

The result is: JS: ip -2029999936

But in fact this is not my IP.

Can you ask me any idea?

Update:

I follow this . I have this code:

Step1. In my component add this code:

import app = require("application");
app.android.context;
      constructor() {
      var context = android.content.Context;
      var wifiManager = app.android.context.getSystemService(context.WIFI_SERVICE);
      var wInfo = wifiManager.getConnectionInfo();
      var mac = wInfo.getMacAddress();
        }

Step2.In AndroidManifest.xml add

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

解决方案

You should have ACCESS_WIFI_STATE permission in AndroidManifest.xml for capturing IP address.

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

Then all you have to is,

import * as application from 'tns-core-modules/application';
declare var android;

const wifiManager = application.android.context.getSystemService(android.content.Context.WIFI_SERVICE);
const connectionInfo = wifiManager.getConnectionInfo();
const ip = android.text.format.Formatter.formatIpAddress(connectionInfo.getIpAddress());

declare var android; is to avoid TS errors while access native apis. An alternative is to install tns-platform-declarations plugin and point the declaration files in your references.d.ts.

Regarding the Mac Address, since Android 6.0

So it doesn't seem officially supported.
