以下是一个简单的安卓应用通过HTTPS请求获取数据的示例代码:
import android.os.AsyncTask;
import android.util.Log;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class HttpsRequestTask extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... params) {
String urlString = params[0];
try {
URL url = new URL(urlString);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setConnectTimeout(5000);
connection.setReadTimeout(5000);
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
return response.toString();
} else {
Log.e("HttpsRequest", "HTTP error code: " + responseCode);
return null;
}
} catch (Exception e) {
Log.e("HttpsRequest", "Exception: " + e.getMessage());
return null;
}
}
@Override
protected void onPostExecute(String result) {
if (result != null) {
Log.d("HttpsRequest", "Response: " + result);
} else {
Log.d("HttpsRequest", "Failed to get response");
}
}
}
