android与后台请求的例子

public static ClientResponse SendClientRequest(List<BasicNameValuePair> params){    ClientResponse clientResponse = new ClientResponse();    List<ClientResponseData> clientResponseDataList = new ArrayList<>();    clientResponse.setClientResponseDataList(clientResponseDataList);    String url = Switch.url + "ReturnClientInfo";

HttpClient httpClient = new DefaultHttpClient();    httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,5000);    httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,5000);    HttpPost httpPost = new HttpPost(url);    try{        Log.i("66666666666666666666", "66666666666666666666");        httpPost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));

HttpResponse httpResponse = httpClient.execute(httpPost);

if(httpResponse.getStatusLine().getStatusCode() == 200)        {            StringBuilder builder = new StringBuilder();            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent()));            for(String s = bufferedReader.readLine();s != null; s = bufferedReader.readLine())            {                builder.append(s);            }            Log.i("builder",builder.toString());

JSONObject jsonObjectBoss =  new JSONObject(builder.toString());            String jsonObjectStatus = jsonObjectBoss.getString("status");            String jsonObjectMsg = jsonObjectBoss.getString("msg");

if(jsonObjectStatus.equals("success")) {                JSONArray jsonArray = jsonObjectBoss.getJSONArray("content");                for (int i = 0; i < jsonArray.length(); i++) {                    JSONObject jsonObject = (JSONObject) jsonArray.get(i);                    ClientResponseData clientResponseData = new ClientResponseData();                    clientResponseData.setClient_id(jsonObject.getString("client_id"));                    clientResponseData.setClient_name(jsonObject.getString("client_name"));                    clientResponseData.setClient_phone(jsonObject.getString("client_phone"));                    clientResponseData.setClient_picture(jsonObject.getString("client_picture"));                    clientResponseData.setClient_address(jsonObject.getString("client_address"));                    clientResponseData.setUser_id(jsonObject.getString("user_id"));                    clientResponse.getClientResponseDataList().add(clientResponseData);                }            }            clientResponse.setStatus(jsonObjectStatus);            clientResponse.setMsg(jsonObjectMsg);        }        else        {            clientResponse.setStatus("error_msg");            clientResponse.setMsg("返回错误码");        }

}catch (Exception e)    {        e.printStackTrace();        clientResponse.setStatus("request_error");        clientResponse.setMsg("请求错误");    }    return clientResponse;}

这是ClientResponse类：

public class ClientResponse extends Response{    List<ClientResponseData> clientResponseDataList;

public List<ClientResponseData> getClientResponseDataList() {        return clientResponseDataList;    }

public void setClientResponseDataList(List<ClientResponseData> clientResponseDataList) {        this.clientResponseDataList = clientResponseDataList;    }}

这是ClientResponseData类：

public class ClientResponseData implements Serializable{    private String client_id;    private String client_name;    private String client_phone;    private String client_address;    private String client_picture;    private String user_id;

public String getClient_id() {        return client_id;    }

public String getClient_name() {        return client_name;    }

public void setClient_name(String client_name) {        this.client_name = client_name;    }

public String getUser_id() {        return user_id;    }

public void setUser_id(String user_id) {        this.user_id = user_id;    }

public String getClient_picture() {

return client_picture;    }

public void setClient_picture(String client_picture) {        this.client_picture = client_picture;    }

public String getClient_address() {

return client_address;    }

public void setClient_address(String client_address) {        this.client_address = client_address;    }

public String getClient_phone() {

return client_phone;    }

public void setClient_phone(String client_phone) {        this.client_phone = client_phone;    }

public void setClient_id(String client_id) {        this.client_id = client_id;    }}这是Switch类：

public class Switch {    public static String url =http://115.29.40.90/GoodsManager/index.php/Home/Index/;}

接下来是客户端要给服务端传送的数据：

1、返回仓库的所有物品信息，不用传参数

http://115.29.40.90/GoodsManager/index.php/Home/Index/ReturnStoreInfo

服务端接收后返回给客户端的信息：

         失败后的返回数据：             ‘status‘ => ‘error‘,             ‘msg‘ => ‘查询错误或者无查询结果‘,             ‘content‘ => ‘null‘

         成功后的返回数据：

‘status‘ => ‘success‘,             ‘msg‘ => ‘查询成功‘,             ‘content‘ => $data       //这是返回的商品内容

2、给仓库添加物品

http://115.29.40.90/GoodsManager/index.php/Home/Index/IntoStorage

客户端需要传送的数据：

goods_id:物品id，形如：’00001’

goods_num:物品数量，形如：‘2000’

goods_name:物品名称，形如：‘电脑’

goods_vender:生产厂家，形如：‘华硕电脑城’

goods_type:型号，形如：‘Xl520’

goods_norms:物品规格，形如：‘合格’

storageUnitName:生产单位名称，形如：‘广州电脑城’

operator:送货或者提货人的姓名，形如：‘小明’

in_out:出库还是入库：1代表出库，0代表入库，这是int

day:出库或者入库的日，形如：‘1日’

month:出库或者入库的月期，形如：‘5月’

year:出库或者入库的年期，形如：‘2016年’

服务端接收后返回给客户端的数据： 

插入成功： 

‘status‘ => ‘success‘,‘msg‘    => ‘插入成功‘,‘content‘=> ‘null‘

插入错误：

‘status‘ => ‘error‘,‘msg‘    => ‘插入错误‘,‘content‘=> ‘null‘

网络错误等原因：

‘status‘ => ‘error‘,‘msg‘    => ‘查询错误‘,‘content‘=> ‘null‘

商品已经存在，不能重复插入：

‘status‘ => ‘exist‘,‘msg‘    => ‘商品已存在‘,‘content‘=> ‘null‘

3、删除物品

http://115.29.40.90/GoodsManager/index.php/Home/Index/DeleteStorage

客户端需要传送的数据：

goods_id：物品id

商品不存在：

‘status‘ => ‘noexist‘,‘msg‘    => ‘用户不存在‘,‘content‘=> ‘null‘

由于网络等原因造成的失败：

‘status‘ => ‘error‘,‘msg‘    => ‘查询错误‘,‘content‘=> ‘null‘

删除成功：

‘status‘ => ‘success‘,‘msg‘    => ‘删除成功‘,‘content‘=> ‘null‘

4、按日期返回入库或者出库物品信息

http://115.29.40.90/GoodsManager/index.php/Home/Index/ReadByDay

客户端需要传送的数据：

day：日期

返回成功：

‘status‘ => ‘success‘,‘msg‘    => ‘返回成功‘,‘content‘=> $end,           //这是返回的商品内容‘num‘ => $data              //这是返回的商品数量

仓库没有记录：

‘status‘ => ‘none‘,‘msg‘    => ‘返回空值‘,‘content‘=> ‘null‘,‘num‘ => $data

请求错误（由于网络原因等等）：

‘status‘ => ‘error‘,‘msg‘    => ‘请求错误‘,‘content‘=> ‘null‘,‘num‘ => ‘0‘

5、按月期返回入库或者出库的物品信息

http://115.29.40.90/GoodsManager/index.php/Home/Index/ReadByMonth

客户端需要传送的数据：

month：月期

6、按年期返回入库或者出库的物品信息

http://115.29.40.90/GoodsManager/index.php/Home/Index/ReadByYear

客户端需要传送的数据：

year：年期

5和6的服务端返回值跟4的一样；

android调用的格式是：

List<BasicNameValuePair>  pairs = null;

ClientResponse clientResponse = null;pairs = new ArrayList<>();pairs.add(new BasicNameValuePair("user_id", “1881555100”));clientResponse = FuckyApi.SendClientRequest(pairs);

这样就返回了clientResponse的实例。
