HttpClient和HttpUrlConnection的请求网路

请求网络

public class NetWorkUtils {
public static String getString(String path){
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(path);

try {
HttpResponse response = client.execute(get);
if(response.getStatusLine().getStatusCode()==200){
String string = EntityUtils.toString(response.getEntity(), "utf-8");
return string;
}
} catch (Exception e) {
e.printStackTrace();
}    return null;
}

public class NetWorkUtils {
public static String getString(String path){
try {
URL url =new URL(path);
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setConnectTimeout(5*1000);
conn.setReadTimeout(5000);
conn.setRequestMethod("GET");
int code = conn.getResponseCode();
