本文介绍了一个基于AsyncHttpClient的网络请求封装方案，适用于Android平台。该方案通过创建HttpUtil类简化了HTTP请求流程，并利用AsyncHandler接口处理请求结果。此外，还提供了一个网络状态检测类NetUtil确保在网络可用的情况下进行请求。

接口类：AsyncHandler.java

package com.hxsmart.intelligentizepos.util;

/**
 * Developer : xiongwenwei@aliyun.com
 * Create Time :
 * Function：
 */
public interface AsyncHandler {
    public void onSuccess(String json);
    public void onFailure(String error);
}

HttpUtil.java

package com.hxsmart.intelligentizepos.util;

import android.content.Context;

import com.hxsmart.intelligentizepos.application.IntelligentizeApplication;
import com.loopj.android.http.AsyncHttpClient;
import com.loopj.android.http.BaseJsonHttpResponseHandler;

import org.apache.http.Header;
import org.apache.http.entity.StringEntity;
import org.json.JSONObject;


/**
 * Developer : xiongwenwei@aliyun.com
 * Create Time :2016-5-23 14:05:26
 * Function：网络请求框架AsyncHttp二次封装
 */
public class HttpUtil {

    /**
     * @param url     API接口地址
     * @param params  请求参数
     * @param handler 请求结果
     */
    public void post(Context context,String url, JSONObject params, final AsyncHandler handler) {
        if(NetUtil.checkNetworkAvailable(IntelligentizeApplication.getInstance())){
            try {
                SharedPreferencesUtils msp = new SharedPreferencesUtils(context);
                String host = "http://"+msp.get(SharedPreferencesUtils.SVRIP,"")+":"+msp.get(SharedPreferencesUtils.SVRPORT,"")+"/";
                LogUtil.i("请求地址", host + url);
                LogUtil.i("请求参数", params.toString());

                AsyncHttpClient client = new AsyncHttpClient();
                client.setTimeout(10 * 1000);//设置超时:10秒
                StringEntity entity = new StringEntity(params.toString(), "UTF-8");
                String contentType = "application/json";//返回数据类型;charset=utf-8
                client.post(IntelligentizeApplication.getInstance(), ApiUtil.HOST + url, entity, contentType, new BaseJsonHttpResponseHandler<String>() {

                    @Override
                    public void onSuccess(int i, Header[] headers, String s, String s2) {
                        try {
                            handler.onSuccess(s);
                            LogUtil.i("请求结果", s );
                        } catch (Exception e) {
                            handler.onSuccess(null);
                            e.printStackTrace();
                        }
                    }

                    @Override
                    public void onFailure(int i, Header[] headers, Throwable throwable, String s, String s2) {
                        handler.onFailure("网络请求失败!");
                        LogUtil.i("请求结果", "本次网络请求失败！！！");
                    }

                    @Override
                    protected String parseResponse(String s, boolean b) throws Throwable {
                        return null;
                    }
                });
            } catch (Exception e) {
                e.printStackTrace();
            }
        }else{
            LogUtil.i("请求结果","无网络连接!");
            ToastUtil.show("无网络连接!");
        }
    }
}

使用：

HttpUtil httpUtil = new HttpUtil();
                    httpUtil.post(context,ApiUtil.GetSms, getSmsParams(etPhoneNumber.getText().toString()), new AsyncHandler() {
                        @Override
                        public void onSuccess(String json) {
                            GetSmsBean bean = BeanUtil.getBean(json, GetSmsBean.class);
                            if (bean.getRetCode().equals("00")) {
                                //变换布局、发送计时器
                                includePhone.setVisibility(View.GONE);
                                includeSmsCode.setVisibility(View.VISIBLE);
                                Message message = handler.obtainMessage(1);
                                handler.sendMessageDelayed(message, 0); //发送message
                                ToastUtil.show(bean.getTip());
                            } else {
                                ToastUtil.show("获取短信验证码失败");
                            }
                        }

                        @Override
                        public void onFailure(String error) {
                            ToastUtil.show(error);
                        }
                    });

网络检测类：NetUtil.java

package com.hxsmart.intelligentizepos.util;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;

/**
 * Developer : xiongwenwei@aliyun.com
 * Create Time :2016-5-23 13:36:53
 * Function：检查设备是否有网络
 */
public class NetUtil {
    // 检测网络
    public static boolean checkNetworkAvailable(Context context) {
        ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        if (connectivity == null) {
            LogUtil.i(null, "couldn't get connectivity manager");
        } else {
            NetworkInfo[] info = connectivity.getAllNetworkInfo();
            if (info != null) {
                for (int i = 0; i < info.length; i++) {
                    if (info[i].isAvailable()) {
//                        LogUtil.i(null, "network is available");
                        return true;
                    }
                }
            }
        }
//        LogUtil.i(null, "network is not available");
        return false;
    }
}
