以下是一个示例的Android通用WebService响应方法的解决方法:
首先,在你的Android项目中创建一个类,命名为WebServiceUtil,用于处理WebService请求和响应。
import android.os.AsyncTask;
import android.util.Log;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpConnectionParams;
import org.apache.http.params.HttpParams;
import org.apache.http.protocol.HTTP;
import org.json.JSONObject;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
public class WebServiceUtil {
private static final String TAG = "WebServiceUtil";
private static final int TIMEOUT = 30000; // 设置连接超时时间为30秒
public static void callWebService(String url, JSONObject jsonRequest, WebServiceCallback callback) {
new WebServiceTask(url, jsonRequest, callback).execute();
}
private static class WebServiceTask extends AsyncTask {
private String url;
private JSONObject jsonRequest;
private WebServiceCallback callback;
public WebServiceTask(String url, JSONObject jsonRequest, WebServiceCallback callback) {
this.url = url;
this.jsonRequest = jsonRequest;
this.callback = callback;
}
@Override
protected String doInBackground(Void... params) {
String response = null;
try {
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, TIMEOUT);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT);
HttpClient httpClient = new DefaultHttpClient(httpParams);
HttpPost httpPost = new HttpPost(url);
httpPost.setHeader("Content-Type", "application/json; charset=utf-8");
httpPost.setEntity(new StringEntity(jsonRequest.toString(), HTTP.UTF_8));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
if (httpEntity != null) {
InputStream inputStream = httpEntity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, HTTP.UTF_8));
StringBuilder stringBuilder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
stringBuilder.append(line);
}
response = stringBuilder.toString();
}
} catch (Exception e) {
Log.e(TAG, "Error calling web service: " + e.getMessage());
}
return response;
}
@Override
protected void onPostExecute(String response) {
if (callback != null) {
callback.onWebServiceCallComplete(response);
}
}
}
public interface WebServiceCallback {
void onWebServiceCallComplete(String response);
}
}
然后,在你的Activity或Fragment中使用上述的WebServiceUtil类来调用WebService,并处理响应。
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import org.json.JSONException;
import org.json.JSONObject;
public class MainActivity extends AppCompatActivity implements WebServiceUtil.WebServiceCallback {
private static final String TAG = "MainActivity";
private static final String WEB_SERVICE_URL = "http://example.com/webservice";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 构建请求参数
JSONObject jsonRequest = new JSONObject();
try {
jsonRequest.put("param1", "value1");
jsonRequest.put("param2", "value2");
} catch (JSONException e) {
e.printStackTrace();
}
// 调用WebService
WebServiceUtil.callWebService(WEB_SERVICE_URL, jsonRequest, this);
}
@Override
public void onWebServiceCallComplete(String response) {
// 在这里处理WebService的响应
if (response != null) {
try {
JSONObject jsonResponse = new JSONObject(response);
// 解析响应数据
String result = jsonResponse.getString("result");
Log.d(TAG, "WebService response: " + result);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
在上述代码中,首先在Activity的onCreate()方法中构建WebService请求的JSON参数,然后调用WebServiceUtil的callWebService()方法来发起WebService请求。当请求完成后,WebServiceUtil会调用MainActivity中的onWebServiceCallComplete()方法,你可以在该方法中处理WebService的响应数据。
请注意,上述示例代码仅供参考,实际使用时,你需要根据自己的
