java - 尝试检索 SSID

Question

我正在尝试构建一个基于 Windows 的 Web 小程序来获取 PC 连接到的 SSID！这就是我目前正在做的事情，但我很想看到另一种方法或对此的改进。这个想法是让 JavaScript 向小程序发送请求，然后将来自 Java 小程序的响应附加到文本框的值中。

JavaScript

 var ssid = applet.getNetworkParameter("SSID", networkInterface);

爪哇

public String getNetworkParameter(final String parameter, final String arg1){
setAppletStringReturnValue("");
AccessController.doPrivileged(new PrivilegedAction(){
  public Object run() {
    try {
if (osName.indexOf("win") > -1)
{
  this.osNetDriver = new Windows7NetServices();
}

if (parameter.equals("SSID")){
        SmartConfig.this.setAppletStringReturnValue(SmartConfig.this.osNetDriver.getSSID(arg1));
 }
  }
    }
    return null;
  }
 });
return this.appletStringValue;
}


public String getSSID(String interfaceName){
try
{
String cmd = "NETSH WLAN SHOW INTERFACE";
boolean parsingAllowed = false;
Runtime run = Runtime.getRuntime();
Process pr = run.exec(cmd);
pr.waitFor();

BufferedReader buf = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String line = "";
while ((line = buf.readLine()) != null)
{
  String[] arr = line.split(":");
  if (arr.length >= 2)
  {
    String parameter = arr[0].trim();
    String value = arr[1].trim();

    if (parameter.equals("Name"))
    {
      parsingAllowed = value.equals(interfaceName);
    }

    if ((parameter.equals("SSID")) && (parsingAllowed))
    {
      return value;
    }
  }
}
}
return "";
}
