Android根本Http基本通信

Android基本Http基本通信

关于http通信的其实自己也不是很懂，就是略微知道一些基本的通信方法

方法1：

   DefaultHttpClient httpclient = new DefaultHttpClient();// 创建http客户端

   HttpGet httpget = new HttpGet(httpUrl); 

   HttpResponse response = httpclient.execute(httpget);

   HttpEntity entity = response.getEntity();//得到http的内容

   response.getStatusLine().getStatusCode();//得到http的状态返回值

   result = EntityUtils.toString(response.getEntity());//得到具体的返回值，一般是xml文件

   entity.consumeContent();//如果entity不为空，则释放内存空间

       httpclient.getCookieStore();//得到cookis

   httpclient.getConnectionManager().shutdown();//关闭http客户端

方法2：

DefaultHttpClient httpclient = new DefaultHttpClient();

  HttpPost httpPost = new HttpPost(httpUrl);

  httpclient.setCookieStore(DataDefine.mCookieStore);

  HttpParams params = httpclient.getParams(); // 计算网络超时用

  HttpConnectionParams.setConnectionTimeout(params, 5 * 1000);

  HttpConnectionParams.setSoTimeout(params, 2 * 1000);

  httpPost.setHeader("Content-Type", "text/xml"); 

  StringEntity httpPostEntity = new StringEntity(base64, "UTF-8");//base64是经过编码的字符串，可以理解为字符串

  //StringEntity httpPostEntity = new StringEntity("UTF-8");

  httpPost.setEntity(httpPostEntity);

  HttpResponse response = httpclient.execute(httpPost);
