httpclient方式提交資料到伺服器

標籤：

get方式:
            //使用HttpClient請求伺服器將使用者密碼發送伺服器驗證
                try{
                String path = "http://192.168.13.83:8080/xuexi/servlet/LoginServlet?username="+URLEncoder.encode(username,"utf-8")+"&pwd="+URLEncoder.encode(password,"utf-8");
                //1.建立一個httpClient對象
                HttpClient httpclient = new DefaultHttpClient();
                
                //2.佈建要求的方式
                HttpGet httpget = new HttpGet(path);
                //3.執行一個http請求
                HttpResponse response = httpclient.execute(httpget);
                //4.擷取請求的狀態代碼，
                StatusLine statusLine = response.getStatusLine();
                int code = statusLine.getStatusCode();
                
                //5.判斷狀態代碼後擷取內容
                if(code == 200){
                    HttpEntity entity = response.getEntity();//擷取實體內容，中封裝的有http請求返回的流資訊
                    InputStream inputStream = entity.getContent();
                    //將流資訊轉換成字串
                    String result = StreamUtils.streamToString(inputStream);
                    
                    Message msg = Message.obtain();
                    msg.what = 1;
                    msg.obj = result;
                    handler.sendMessage(msg);
                }
                
                }catch (Exception e) {
                    e.printStackTrace();
                }

 

    post方式：

            //使用UrlConncetion請求伺服器將使用者密碼發送伺服器驗證

                        //1.建立一個httpclient對象
                        HttpClient httpclient = new DefaultHttpClient();
                        //2.建立一個請求方式
                        HttpPost httppost = new HttpPost(path);
                        //建立集合封裝資料
                        ArrayList<BasicNameValuePair> arrayList = new ArrayList<BasicNameValuePair>();
                        BasicNameValuePair nameValuePair = new BasicNameValuePair("username",username);
                        arrayList.add(nameValuePair);
                        BasicNameValuePair nameValuePair1 = new BasicNameValuePair("pwd",password);

                        //建立一個Entity
                        UrlEncodedFormEntity entity = new UrlEncodedFormEntity(arrayList, "utf-8");
                        //佈建要求時的內容
                        httppost.setEntity(entity);
                        
                        //3.執行一個請求,返回一個response對象
                        HttpResponse response = httpclient.execute(httppost);
                        //4.擷取狀態代碼
                        int code = response.getStatusLine().getStatusCode();
                        //5.判斷並擷取內容
                        if(code == 200){
                            HttpEntity entity1 = response.getEntity();//擷取實體內容，中封裝的有http請求返回的流資訊
                            InputStream inputStream = entity1.getContent();
