在Nativescript中获取mac地址和ip [英] Get mac address and ip in Nativescript

问题描述

我们正在实现服务器分发应用程序，我们需要通过以下方式限制对应用程序的访问:

• mac地址
• ip

目前，我还没有找到任何模块可以使用nativescript从设备中获取此数据，所以我不知道是否有插件，或者我怎么能实现这一目标.

解决方案

在nativescript中，您可以访问设备的本地api 因此，如果没有任何模块/插件，则可以使用此选项访问本机api. https://docs.nativescript.org/core-concepts/使用javascript访问本机apis

例如，在此处 在JAVA中:

WifiManager wifiManager = (WifiManager)  getSystemService(Context.WIFI_SERVICE);
WifiInfo wInfo = wifiManager.getConnectionInfo();
String mac = wInfo.getMacAddress();

我们可以像这样用javascript编写它:

首先，我们应该在getSystemService的位置罚款:

搜索android文档后，我们发现:

getSystemService在android.content.Context中 用于访问本机脚本中的上下文 http://docs.nativescript.org/cookbook/application

我们可以做到:

import app = require("application");
app.android.context;

所以让我们用javascript来编写它:

我们在javascript中没有类型，所以我们改用var;

  var context = android.content.Context;
  var wifiManager = app.android.context.getSystemService(context.WIFI_SERVICE);
  var wInfo = wifiManager.getConnectionInfo();
  var mac = wInfo.getMacAddress();

注意1:如上面的java解决方案链接中所述，您应该将此权限<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>添加到app/App_Resources/AndroidManifest

注2:以上解决方案适用于android，对于ios，您应该找到具有Objective_c的解决方案，并借助nativescript文档转换为javascript.

注意3:在android 6中，您可能需要请求权限

您还可以使用此方法为本地脚本创建插件.

We are implementing a server for app distribution and we need restrict the access to the apps by:

• mac address
• ip

At the moment I have not found any module that can obtain this data from the device in nativescript, so i don't know if there's a plugin or how else can I achieve this.

解决方案

In nativescript you can access native apis of device so if there isn't any module/plugin for it you can use this option for accessing native apis. https://docs.nativescript.org/core-concepts/accessing-native-apis-with-javascript

for example there is solution for mac adress here in JAVA:

WifiManager wifiManager = (WifiManager)  getSystemService(Context.WIFI_SERVICE);
WifiInfo wInfo = wifiManager.getConnectionInfo();
String mac = wInfo.getMacAddress();

we can write it in javascript like this:

first we should fine where is this getSystemService:

after searching in documentation of android we found:

getSystemService is in android.content.Context for accessing context in nativescript http://docs.nativescript.org/cookbook/application

we can do:

import app = require("application");
app.android.context;

so let's write it in javascript:

we don't have types in javascript so we use var instead;

  var context = android.content.Context;
  var wifiManager = app.android.context.getSystemService(context.WIFI_SERVICE);
  var wInfo = wifiManager.getConnectionInfo();
  var mac = wInfo.getMacAddress();

NOTE1 : as mentioned in above java solution link you should add this permision <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> to app/App_Resources/AndroidManifest

NOTE2 : the above solution was for android,for ios you should find the solution with objective_c and convert to javascript with help of nativescript documentation.

NOTE3:In android 6 you might need request permision

You can also use this method to create a plugin for nativescript.
