Android之HttpPost与HttpGet使用

一）HttpGet :doGet()方法
//doGet():将参数的键值对附加在url后面来传递
        public String getResultForHttpGet(String name,String pwd) throws ClientProtocolException, IOException{
                //服务器  ：服务器项目  ：servlet名称
                String path="http://192.168.5.21:8080/test/test";
                String uri=path+"?name="+name+"&pwd="+pwd;
                //name:服务器端的用户名，pwd:服务器端的密码
                //注意字符串连接时不能带空格

                String result="";

                HttpGet httpGet=new HttpGet(uri);
                //取得HTTP response
                HttpResponse response=new DefaultHttpClient().execute(httpGet);
                //若状态码为200
                if(response.getStatusLine().getStatusCode()==200){
                        //取出应答字符串
                        HttpEntity entity=response.getEntity();
                        result=EntityUtils.toString(entity, HTTP.UTF_8);
                }
                return result;
        }

（二）HttpPost ：doPost()方法
//doPost():将参数打包到http报头中传递
        public String getReultForHttpPost(String name,String pwd) throws ClientProtocolException, IOException{
                //服务器  ：服务器项目  ：servlet名称
                String path="http://192.168.5.21:8080/test/test";
                HttpPost httpPost=new HttpPost(path);
                //注意：httpPost方法时，传递变量必须用NameValuePair[]数据存储，通过httpRequest.setEntity()方法来发出HTTP请求
                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);
                //若状态码为200
                if(response.getStatusLine().getStatusCode()==200){
                        //取出应答字符串
                        HttpEntity entity=response.getEntity();
                        result=EntityUtils.toString(entity, HTTP.UTF_8);
                }
                return result;
        }
