android---HttpGet访问服务器

HttpClientUtil在之前的HttpPost中已经定义过了，就不再重复贴出代码。，GET跟post的实现方法基本差不多。

package com.example.httpget;

import java.util.Map;

import org.apache.http.HttpResponse;

import org.apache.http.HttpStatus;

import android.os.Handler;

import android.os.Message;

import cn.leature.istarbaby.utils.InputStreamTransferUtil;

public class HttpGetUtil{

public static final int HTTP_GET_DONE = 1;

public static final int HTTP_GET_ERROR = 0;

private Handler handler;

private int mRequestCode;

public HttpGetUtil(Handler handler,int requestCode)

{

this.handler = handler;

this.mRequestCode = requestCode;

}

private void requestWithHttpGet(String requestUrl,

Map<String, String> params) {

int resultCode = 0;

String result = "";

try {

HttpResponse response = HttpClientUtil.executeWithGet(requestUrl,

params);

if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {

resultCode = HTTP_GET_DONE;

result = InputStreamTransferUtil.inputStream2String(response

.getEntity().getContent());

} else {

resultCode = HTTP_GET_ERROR;

}

} catch (Exception e) {

e.printStackTrace();

resultCode = HTTP_GET_ERROR;

} finally {

// 返回结果

sendMessage(resultCode, result);

}

}

public void execute(final String requestUrl,

final Map<String, String> params) {

new Thread(new Runnable() {

@Override

public void run() {

requestWithHttpGet(requestUrl, params);

}

}).start();

}

private void sendMessage(int responseCode, String responseMessage) {

Message msg = Message.obtain();

msg.arg1 = mRequestCode;

msg.obj = responseMessage;

msg.what = responseCode;

handler.sendMessage(msg);

}

}
