// http地址 String httpUrl = "http://192.168.1.110:8080/httpget.jsp"; //HttpPost连接对象 HttpPost httpRequest = new HttpPost(httpUrl); //使用NameValuePair来保存要传递的Post参数 List<NameValuePair> params = new ArrayList<NameValuePair>(); //添加要传递的参数 params.add(new BasicNameValuePair("par", "HttpClient_android_Post")); //设置字符集 HttpEntity httpentity = new UrlEncodedFormEntity(params, "gb2312"); //请求httpRequest httpRequest.setEntity(httpentity); //取得默认的HttpClient HttpClient httpclient = new DefaultHttpClient(); //取得HttpResponse HttpResponse httpResponse = httpclient.execute(httpRequest); //HttpStatus.SC_OK表示连接成功 if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK){ //取得返回的字符串 String strResult = EntityUtils.toString(httpResponse.getEntity()); System.out.println(strResult); }else{ System.out.println("请求错误!"); }
