Android网络通信的基本实现

似乎很久没有写博客了，今天无意间看了下半年前写的代码，设计似乎很有局限性，但基本的通信也算是实现了。

不知道以后看到现在写的代码会不会也会有这样的想法呢？

进入正题，android网络通信的基本实现的有两种方式，一种是通过HttpClient来实现，一种是通过HttpURLConnection来实现。

直接上代码：

首先是一个抽象的http类

/** * 抽象的Http * @author Jenly * @date 2014-8-7 * */public abstract class AbstractHttp {/** 默认编码  (UTF-8) */public static final String DEFAULT_ENCODING = "UTF-8";    /** GET请求时 url和 参数的分隔符 */    public static final String URL_AND_PARA_SEPARATOR = "?";/** 是否取消请求 */    protected boolean isCancel = false;    public static final int DEFAULT_BYTE_LENGTH = 8192;protected static final int LONG_TIME = 0;protected int connectionTimeOut = LONG_TIME;protected int soTimeOut = LONG_TIME;public enum HttpMethod{/** GET请求 */GET,/** POST请求 */POST}/** * 构造 */public AbstractHttp(){super();}public AbstractHttp(int connectionTimeOut,int soTimeOut){super();if(connectionTimeOut<0 || soTimeOut <0){throw new RuntimeException("connectionTimeOut<0 || soTimeOut<0");}if(connectionTimeOut>0)this.connectionTimeOut = connectionTimeOut;if(soTimeOut>0)this.soTimeOut = soTimeOut;}//-----------------------------------------/** * 取消请求 */protected void cancel(){isCancel = true;}/** * 异步线程 * @param runnable */protected void asyncThread(Runnable runnable){new Thread(runnable).start();}/** * 异步连接  默认GET请求 * @param url * @param httpCallBack */public abstract void asyncConnect(String url,HttpCallBack<String> httpCallBack);/** * 异步连接  默认GET请求 * @param url * @param params * @param httpCallBack */public abstract void asyncConnect(String url,Map<String,String> params,HttpCallBack<String> httpCallBack);/** * 异步连接 * @param url * @param params * @param httpMethod * @param httpCallBack */public abstract void asyncConnect(String url,Map<String,String> params,HttpMethod httpMethod,HttpCallBack<String> httpCallBack);/** * 同步连接  默认GET请求 * @param url * @param httpEntity * @param httpCallBack */public abstract String syncConnect(String url);/** * 同步连接  默认GET请求 * @param url * @param params */public abstract String syncConnect(String url,Map<String,String> params);/** * 同步连接  默认GET请求 * @param url * @param params * @param httpMethod */public abstract String syncConnect(String url,Map<String,String> params,HttpMethod httpMethod);/** * 同步连接  默认GET请求 * @param url * @param httpEntity * @param httpCallBack */public abstract String syncConnect(String url,Map<String,String> params,HttpCallBack<String> httpCallBack);/** * 同步连接 * @param url * @param params * @param httpMethod * @param httpCallBack */public abstract String syncConnect(String url,Map<String,String> params,HttpMethod httpMethod,HttpCallBack<String> httpCallBack);/** * 异步下载文件 * @param url * @param fileName * @param httpDownloadCallBack * @return */public abstract void asyncDownloadFile(String url,String fileName,HttpCallBack<File> httpDownloadCallBack);/** * 同步下载文件 * @param url * @param fileName * @return */public abstract File syncDownloadFile(String url,String fileName);/** * 同步下载文件 * @param url * @param fileName * @param httpDownloadCallBack * @return */public abstract File syncDownloadFile(String url,String fileName,HttpCallBack<File> httpDownloadCallBack);}

监听回调接口：

/** * Http连接回调接口 * @author Jenly * @date 2014-8-7 */public interface HttpCallBack<T>{/** * 开始 * @param url */void onStart(String url);/** * 加载… * @param progress * @param count */void onLoading(long progress,long count);/** * 成功 * @param t 返回的对象 */void onSuccess(T t);/** * 失败 * @param error * @param e */void onFailure(String error,Throwable e);/** * 取消 */void onCancel();}

/** * Http连接请求回调 * @author Jenly * @date 2014-8-7 */public abstract class HttpConnectCallBack implements HttpCallBack<String>{@Overridepublic abstract void onSuccess(String content);}

/** * Http下载回调 * @author Jenly * @date 2014-8-7 */public abstract class HttpDownloadCallBack implements HttpCallBack<File>{@Overridepublic abstract void onSuccess(File file);}

通过HttpClient实现的方式

/** * Http网络通信(httpClient实现) * @author Jenly * @date 2014-8-7 */public class Http extends AbstractHttp{public Http() {super();}public Http(int connectionTimeOut, int soTimeOut) {super(connectionTimeOut, soTimeOut);}/** * 获得一个HttpClient * @return */private HttpClient getHttpClient(){HttpParams httpParams = new BasicHttpParams();if(connectionTimeOut != LONG_TIME && soTimeOut != LONG_TIME){HttpConnectionParams.setConnectionTimeout(httpParams,connectionTimeOut);HttpConnectionParams.setSoTimeout(httpParams, soTimeOut);}HttpConnectionParams.setTcpNoDelay(httpParams, true);HttpConnectionParams.setSocketBufferSize(httpParams,DEFAULT_BYTE_LENGTH);HttpProtocolParams.setVersion(httpParams, HttpVersion.HTTP_1_1);SchemeRegistry schemeRegistry = new SchemeRegistry();schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));schemeRegistry.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));ThreadSafeClientConnManager threadSafeClientConnManager = new ThreadSafeClientConnManager(httpParams, schemeRegistry);return new DefaultHttpClient(threadSafeClientConnManager,httpParams);}/** * 获得HttpUriRequest * @param url * @param httpMethod * @param params * @return */private HttpUriRequest getHttpUriRequest(String url,HttpMethod httpMethod,Map<String,String> params){if(HttpMethod.POST == httpMethod){HttpPost httpPost = new HttpPost(url);if(params!=null){List<NameValuePair> list = new ArrayList<NameValuePair>();for(String key : params.keySet()){list.add(new BasicNameValuePair(key, params.get(key)));}try {httpPost.setEntity(new UrlEncodedFormEntity(list,DEFAULT_ENCODING));} catch (UnsupportedEncodingException e) {LogUtils.e(e);}}return httpPost;}else{if(params!=null){List<NameValuePair> list = new ArrayList<NameValuePair>();for(String key : params.keySet()){list.add(new BasicNameValuePair(key, params.get(key)));}url += URL_AND_PARA_SEPARATOR;url += URLEncodedUtils.format(list,DEFAULT_ENCODING);}LogUtils.v("GET:"+ url);HttpGet httpGet = new HttpGet(url);return httpGet;}}@Overridepublic void asyncConnect(String

InputStreamReader(httpResponse.getEntity().getContent()));StringBuffer buffer = new StringBuffer();String line = null;long progress = 0;long count = httpResponse.getEntity().getContentLength();isCancel = false;if(httpCallBack != null && count!=-1)httpCallBack.onLoading(progress, count);while ((!isCancel) && (line = reader.readLine())!=null) {buffer.append(line);if(httpCallBack != null && count!=-1){progress+= line.getBytes().length;httpCallBack.onLoading(progress, count);}}if(httpCallBack != null){if(!isCancel){progress = count;httpCallBack.onLoading(progress, count);}else{reader.close();httpCallBack.onCancel();return null;}}reader.close();if(httpCallBack != null && !isCancel)httpCallBack.onSuccess(buffer.toString());if(httpClient!=null)httpClient.getConnectionManager().shutdown();return buffer.toString();}else{if(httpCallBack !=

url,final String fileName,final HttpCallBack<File> httpDownloadCallBack) {asyncThread(new Runnable() {@Overridepublic void run() {syncDownloadFile(url,fileName,httpDownloadCallBack);}});}@Overridepublic File syncDownloadFile(String url,String fileName) {return syncDownloadFile(url, fileName, null);}public File syncDownloadFile(String url,String fileName,HttpCallBack<File> httpDownloadCallBack) {if(TextUtils.isEmpty(url)){return null;}File file = null;BufferedInputStream bis = null;FileOutputStream fos = null;HttpClient httpClient = null;int statusCode = -1;try {LogUtils.v(url);if(TextUtils.isEmpty(fileName)){return null;}if(httpDownloadCallBack!=null)httpDownloadCallBack.onStart(url);HttpUriRequest httpUriRequest = getHttpUriRequest(url, HttpMethod.GET, null);httpClient = getHttpClient();HttpResponse httpResponse = httpClient.execute(httpUriRequest);statusCode =

{LogUtils.e(e);if(httpDownloadCallBack!=null)httpDownloadCallBack.onFailure(String.valueOf(statusCode), e);}finally{if(httpClient!=null)httpClient.getConnectionManager().shutdown();}return file;}}

通过HttpURLConnection实现的方式：

/** * Http网络通信(HttpURLConnection实现) * @author Jenly * @date 2014-8-7 */public class KingHttp extends AbstractHttp{public KingHttp() {super();}public KingHttp(int connectionTimeOut, int soTimeOut) {super(connectionTimeOut, soTimeOut);}private HttpURLConnection getHttpURLConnection(String url,HttpMethod httpMethod,Map<String,String> params) throws MalformedURLException, IOException{String paras

==httpMethod){httpURLConnection.setDoOutput(true);httpURLConnection.setRequestMethod("POST");LogUtils.v("POST:"+
