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。
