這是我第一次連接到服務器。我正在嘗試將android應用程序的值存儲到運行在我的服務器中的MySQL中。但是，我有問題連接到我的服務器。它顯示「目標服務器無法響應」可能是什麼問題？和解決方案？Android - 無法從服務器獲得響應
的.java類
public void sendRegistrationIdToServer(String deviceId,
String registrationId) {
Log.d("C2DM", "Sending registration ID to my application server");
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://10.28.68.28/test.php?");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
// Get the deviceID
nameValuePairs.add(new BasicNameValuePair("deviceid", deviceId));
nameValuePairs.add(new BasicNameValuePair("registrationid",
registrationId));
//HttpProtocolParams.setUseExpectContinue(client.getParams(), false);
post.addHeader("Content-Type", "application/x-www-form-urlencoded");
post.setEntity(new UrlEncodedFormEntity(nameValuePairs,HTTP.UTF_8));
// Execute HTTP Post Request
HttpResponse response = client.execute(post);
int status = response.getStatusLine().getStatusCode();
System.out.println("HTTP Status = "+status);
BufferedReader rd = new BufferedReader(new InputStreamReader(
response.getEntity().getContent()));
String line = "";
while ((line = rd.readLine()) != null) {
Log.e("HttpResponse", line);
}
} catch (IOException e) {
e.printStackTrace();
}
}

您是否驗證過請求已到達服務器？檢查服務器上的日誌？你能成功使用'curl'嗎？ – nloko 2011-12-30 04:11:18
您確定目標已啓動並且擁有HTTP偵聽器嗎？ – 2011-12-30 04:11:34
嗯，我意識到我沒有任何這些。對不起，如果我問另一個問題，請介意嗎我如何設置這個監聽器？是的，我可以在終端中使用捲曲。 – 2011-12-30 06:57:17
