android平台HttpGet、HttpPost请求实例

使用HttpClient中的HttpGet()方法进行http通信的实例：

/**
*description：Android HttpGet()

*/

package me.gogogoog;

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class MyHttpGetActivity extends Activity{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.result);

TextView resultText = (TextView) this.findViewById(R.id.resultText);

String username="username";
String password="password";

String httpUrl = "http://192.168.1.90:8080/AndroidLogin/loginAction.do?method=login&username="+username+"&password="+password;
//创建httpRequest对象
HttpGet httpRequest = new HttpGet(httpUrl);
try
{
//取得HttpClient对象
HttpClient httpclient = new DefaultHttpClient();
//请求HttpClient，取得HttpResponse
HttpResponse httpResponse = httpclient.execute(httpRequest);
//请求成功
if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK)
{
//取得返回的字符串
String strResult = EntityUtils.toString(httpResponse.getEntity());
resultText.setText(strResult);
}
else
{
resultText.setText("请求错误!");
}
}
catch (ClientProtocolException e)
{
resultText.setText(e.getMessage().toString());
}
catch (IOException e)
{
resultText.setText(e.getMessage().toString());
}
catch (Exception e)
{
resultText.setText(e.getMessage().toString());
}
}
}

使用HttpClient中的HttpPost()方法进行http通信的实例：

/**
*description：Android HttpPost()
*authour:YanEr·Gates
*website:http://www.jb51.net
*/
package me.gogogoog;

import java.io.IOException;

import java.util.ArrayList;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
import android.app.Activity;
import android.widget.TextView;

public class ResultActivity extends Activity{

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.result);

TextView resultText = (TextView) this.findViewById(R.id.resultText);
String username="username";
String password="password";
String httpUrl = "http://192.168.1.90:8080/AndroidLogin/loginAction.do?method=login";

//创建httpRequest对象
HttpPost httpRequest = new HttpPost(httpUrl);

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("username", username));
params.add(new BasicNameValuePair("password", password));

try{
//设置字符集
HttpEntity httpentity = new UrlEncodedFormEntity(params, "gb2312");

//请求httpRequest
httpRequest.setEntity(httpentity);

//取得默认的HttpClient
HttpClient httpclient = new DefaultHttpClient();

//取得HttpResponse
HttpResponse httpResponse = httpclient.execute(httpRequest);

//HttpStatus.SC_OK表示连接成功
if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK){
//取得返回的字符串
String strResult = EntityUtils.toString(httpResponse.getEntity());
resultText.setText(strResult);
}else{
resultText.setText("请求错误!");
}
}catch (ClientProtocolException e){
resultText.setText(e.getMessage().toString());
} catch (IOException e){
resultText.setText(e.getMessage().toString());
}catch (Exception e){
resultText.setText(e.getMessage().toString());
}
