我有一个 wamp 服务器。我已经写了我的安卓客户端。如果我运行该应用程序，则在模拟器上的响应很好……但是相同的代码在真实设备上不起作用，我的意思是我没有得到响应……
这是代码...
public static final String SERVER_URL = "http://192.168.1.3/AndroidListServer/server.php?command=getAnimalList";
private static String executeHttpRequest(String data) {
String result = "";
try {
URL url = new URL(SERVER_URL);
URLConnection connection = url.openConnection();
/*
* We need to make sure we specify that we want to provide input and
* get output from this connection. We also want to disable caching,
* so that we get the most up-to-date result. And, we need to
* specify the correct content type for our data.
*/
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
// Send the POST data
DataOutputStream dataOut = new DataOutputStream(connection.getOutputStream());
dataOut.writeBytes(data);
dataOut.flush();
dataOut.close();
// get the response from the server and store it in result
DataInputStream dataIn = new DataInputStream(connection.getInputStream());
String inputLine;
while ((inputLine = dataIn.readLine()) != null) {
result += inputLine;
}
dataIn.close();
} catch (IOException e) {
/*
* In case of an error, we're going to return a null String. This
* can be changed to a specific error message format if the client
* wants to do some error handling. For our simple app, we're just
* going to use the null to communicate a general error in
* retrieving the data.
*/
e.printStackTrace();
result = null;
}
return result;
