Android之HttpPost與HttpGet使用

一）HttpGet :doGet()方法
//doGet():將參數的鍵值對附加在url后面來傳遞
        public String getResultForHttpGet(String name,String pwd) throws ClientProtocolException, IOException{
                //服務器  ：服務器項目  ：servlet名稱
                String path="http://192.168.5.21:8080/test/test";
                String uri=path+"?name="+name+"&pwd="+pwd;
                //name:服務器端的用戶名，pwd:服務器端的密碼
                //注意字符串連接時不能帶空格
               
                String result="";
               
                HttpGet httpGet=new HttpGet(uri);
                //取得HTTP response
                HttpResponse response=new DefaultHttpClient().execute(httpGet);
                //若狀態碼為200
                if(response.getStatusLine().getStatusCode()==200){
                        //取出應答字符串
                        HttpEntity entity=response.getEntity();
                        result=EntityUtils.toString(entity, HTTP.UTF_8);
                }
                return result;
        }

（二）HttpPost ：doPost()方法
//doPost():將參數打包到http報頭中傳遞
        public String getReultForHttpPost(String name,String pwd) throws ClientProtocolException, IOException{
                //服務器  ：服務器項目  ：servlet名稱
                String path="http://192.168.5.21:8080/test/test";
                HttpPost httpPost=new HttpPost(path);
                //注意：httpPost方法時，傳遞變量必須用NameValuePair[]數據存儲，通過httpRequest.setEntity()方法來發出HTTP請求
                List<NameValuePair>list=new ArrayList<NameValuePair>();
                list.add(new BasicNameValuePair("name", name));
                list.add(new BasicNameValuePair("pwd", pwd));
                httpPost.setEntity(new UrlEncodedFormEntity(list,HTTP.UTF_8));
               
                String result="";
               //取得HTTP response
                HttpResponse response=new DefaultHttpClient().execute(httpPost);
                //若狀態碼為200
                if(response.getStatusLine().getStatusCode()==200){
                        //取出應答字符串
                        HttpEntity entity=response.getEntity();
                        result=EntityUtils.toString(entity, HTTP.UTF_8);
                }
                return result;
        }
