[英]How to connect Android app to an static ip address
我正在尝试开发一个需要通过wifi连接到另一台设备的应用程序。 我知道另一台设备的IP地址,但是当我尝试连接到它时,却无法。
private static String getUrl(String direccion) throws ConnectException{
try {
URL u = new URL("http://192.168.1.216");
HttpURLConnection co = (HttpURLConnection) u.openConnection();
BufferedReader reader = new BufferedReader(new InputStreamReader(co.getInputStream()));
String line;
while ((line = reader.readLine()) != null)
//buffer.append(line);
System.out.println(line);
reader.close();
co.disconnect();
System.out.println("######InputStream CORRECTA... "+u);
return line;
} catch (MalformedURLException e) {
throw new ConnectException();
} catch (java.net.ConnectException e){
throw e;
} catch (IOException e) {
throw new ConnectException();
}
}
您还需要指定以下内容:
co.setRequestMethod("GET");
co.setDoOutput(true);
co.connect();
因此,请尝试以下操作:
private static String getUrl(String direccion) throws ConnectException {
try {
URL u = new URL("http://192.168.1.216");
HttpURLConnection co = (HttpURLConnection) u.openConnection();
co.setRequestMethod("GET");
co.setDoOutput(true);
co.connect();
BufferedReader reader = new BufferedReader(new InputStreamReader(co.getInputStream()));
String line;
while ((line = reader.readLine()) != null)
//buffer.append(line);
System.out.println(line);
reader.close();
co.disconnect();
System.out.println("######InputStream CORRECTA... "+u);
return line;
} catch (MalformedURLException e) {
throw new ConnectException();
} catch (java.net.ConnectException e){
throw e;
} catch (IOException e) {
throw new ConnectException();
}
}
