Android网络常用的请求---HttpURLConnection和HttpClient

<span style="font-size:18px;">/**     * method one:     * */    public static void sendHttpRequest(final String urlStr, final HttpCallBackListener listenser) {        new Thread(new Runnable() {            @Override            public void run() {                HttpURLConnection connection = null;                try {                    URL url = new URL(urlStr);                    connection = (HttpURLConnection) url.openConnection();                    connection.setRequestMethod("GET");                    connection.setConnectTimeout(8000);                    connection.setReadTimeout(8000);                    InputStream in = connection.getInputStream();                    BufferedReader reader = new BufferedReader(new InputStreamReader(in));                    StringBuilder response = new StringBuilder();                    String line;                    while ((line = reader.readLine()) != null) {                        response.append(line);                    }                    if (listenser != null) {                        listenser.onfinish(response.toString());                    }                } catch (Exception e) {                    if (listenser != null) {                        listenser.onError(e);                    }                } finally {                    if (connection != null) {                        connection.disconnect();                    }                }            }        }).start();    }    public interface HttpCallBackListener {        void onfinish(String response);        void onError(Exception e);    }    /**     * method two: HttpClient--HttpGet     * */    public String cookieStr = "";    public String sendRequestWithHttpClient(final String urlStr) {        String response = null;        HttpClient httpClient = new DefaultHttpClient();        HttpGet httpGet = new HttpGet(urlStr);        httpGet.setHeader("Cookie", cookieStr);        HttpResponse httpResponse;        try {            httpResponse = httpClient.execute(httpGet);            if (httpResponse.getStatusLine().getStatusCode() == 200) {                HttpEntity entity = httpResponse.getEntity();                response = EntityUtils.toString(entity, "utf-8");            }        } catch (Exception e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        return response;    }    /**     * method two: HttpClient--HttpPost     * requestBody:"<Result><UserName>MeiMei</UserName></Result>"     */    public synchronized String post(String requestBody, URI url) {        String requestResult = null;        HttpPost httpRequest = new HttpPost();        httpRequest.setURI(url);        httpRequest.setHeader("Cookie", cookieStr);        try {            List<NameValuePair> params = new ArrayList<NameValuePair>();            params.add(new BasicNameValuePair("inputXml", requestBody));            httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));            HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);            if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {                Header[] headers = httpResponse.getAllHeaders();                for (Header header : headers) {                    if ("Set-Cookie".equals(header.getName())) {                        String temp = header.getValue();                        int index = temp.indexOf("Version=");                        cookieStr += temp.substring(0, index);                    }                }                requestResult = EntityUtils.toString(httpResponse.getEntity());            }        } catch (Exception e) {            e.printStackTrace();        }        return requestResult;    }</span>
