问题描述
当我在模拟器中使用IP：10.0.2.2时，它会获得完美的JSON响应。@H_404_1@
现在我想在手机上进行测试。@H_404_1@
我的服务器正在本地计算机上运行。我找到了本地计算机IP，并给URL像新的JsonTask（）。execute（“ http://192.168.x.xxx:8080/rsi/v1”）; 但是我无法获得JSON响应。@H_404_1@
MainActivity.java @H_404_1@
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new JsonTask().execute("http://192.168.x.xxx:8080/rsi/v1");
//new JsonTask().execute("http://127.0.0.1:8080/rsi/v1");//device
//new JsonTask().execute("http://10.0.2.2:8080/rsi/v1");//emulator
}
private class JsonTask extends AsyncTask<String,String,String> {
protected void onPreExecute() {
super.onPreExecute();
pd = new ProgressDialog(MainActivity.this);
pd.setMessage("Please wait");
pd.setCancelable(false);
pd.show();
}
protected String doInBackground(String... params) {
HttpURLConnection connection = null;
BufferedReader reader = null;
try {
URL url = new URL(params[0]);
connection = (HttpURLConnection) url.openConnection();
connection.connect();
InputStream stream = connection.getInputStream();
reader = new BufferedReader(new InputStreamReader(stream));
StringBuffer buffer = new StringBuffer();
String line = "";
while ((line = reader.readLine()) != null) {
buffer.append(line + "\n");
Log.d("TAG","socket===>res==>" + line); //here u ll get whole response...... :-)
}
return buffer.toString();
} catch (MalformedURLException e) {
e.printstacktrace();
} catch (IOException e) {
e.printstacktrace();
} finally {
if (connection != null) {
connection.disconnect();
}
try {
if (reader != null) {
reader.close();
}
} catch (IOException e) {
e.printstacktrace();
}
}
return null;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (pd.isShowing()) {
pd.dismiss();
}
//txtJson.setText(result);
Log.d("TAG","socket====>result===>" + result);
}
}

注意：当我输入链接（http://127.0.0.1:8080/rsi/v1）时，本地计算机的Web浏览器会获得正确的响应。@H_404_1@
请问我做错了什么。@H_404_1@
