方案一：给原生APP提供api接口
使用TP框架时 放在common文件夹下文件名就叫function.php
<?php /** * Created by zhangkx * Email: zkx520tnhb@163.com * Date: 2015/8/1 * Time: 23:15 */ /*************************** api开发辅助函数 **********************/ /** * @param null $msg 返回正确的提示信息 * @param flag success CURD 操作成功 * @param array $data 具体返回信息 * Function descript: 返回带参数，标志信息，提示信息的json 数组 * */ function returnApiSuccess($msg = null,$data = array()){ $result = array( 'flag' => 'Success', 'msg' => $msg, 'data' =>$data ); print json_encode($result); } /** * @param null $msg 返回具体错误的提示信息 * @param flag success CURD 操作失败 * Function descript:返回标志信息 ‘Error'，和提示信息的json 数组 */ function returnApiError($msg = null){ $result = array( 'flag' => 'Error', 'msg' => $msg, ); print json_encode($result); } /** * @param null $msg 返回具体错误的提示信息 * @param flag success CURD 操作失败 * Function descript:返回标志信息 ‘Error'，和提示信息，当前系统繁忙，请稍后重试； */ function returnApiErrorExample(){ $result = array( 'flag' => 'Error', 'msg' => '当前系统繁忙，请稍后重试！', ); print json_encode($result); } /** * @param null $data * @return array|mixed|null * Function descript: 过滤post提交的参数； * */ function checkDataPost($data = null){ if(!empty($data)){ $data = explode(',',$data); foreach($data as $k=>$v){ if((!isset($_POST[$k]))||(empty($_POST[$k]))){ if($_POST[$k]!==0 && $_POST[$k]!=='0'){ returnApiError($k.'值为空！'); } } } unset($data); $data = I('post.'); unset($data['_URL_'],$data['token']); return $data; } } /** * @param null $data * @return array|mixed|null * Function descript: 过滤get提交的参数； * */ function checkDataGet($data = null){ if(!empty($data)){ $data = explode(',',$data); foreach($data as $k=>$v){ if((!isset($_GET[$k]))||(empty($_GET[$k]))){ if($_GET[$k]!==0 && $_GET[$k]!=='0'){ returnApiError($k.'值为空！'); } } } unset($data); $data = I('get.'); unset($data['_URL_'],$data['token']); return $data; } }
查询单个果品详细信息
/** * 发布模块 * * 获取信息单个果品详细信息 * */ public function getMyReleaseInfo(){ //检查是否通过post方法得到数据 checkdataPost('id'); $where['id'] = $_POST['id']; $field[] = 'id,fruit_name,high_price,low_price,address,size,weight,fruit_pic,remark'; $releaseInfo = $this->release_obj->findRelease($where,$field); $releaseInfo['remark'] = mb_substr($releaseInfo['remark'],0,49,'utf-8').'...'; //多张图地址按逗号截取字符串，截取后如果存在空数组则需要过滤掉 $releaseInfo['fruit_pic'] = array_filter(explode(',', $releaseInfo['fruit_pic'])); $fruit_pic = $releaseInfo['fruit_pic'];unset($releaseInfo['fruit_pic']); //为图片添加存储路径 foreach($fruit_pic as $k=>$v ){ $releaseInfo['fruit_pic'][] = 'http://'.$_SERVER['HTTP_HOST'].'/Uploads/Release/'.$v; } if($releaseInfo){ returnApiSuccess('',$releaseInfo); }else{ returnApiError( '什么也没查到(+_+)！'); } }
findRelease() 方法的model
/** * 查询一条数据 */ public function findRelease($where,$field){ if($where['status'] == '' || empty($where['status'])){ $where['status'] = array('neq','9'); } $result = $this->where($where)->field($field)->find(); return $result; }
app端接收到的数据（解码json之后）
{ "flag": "success", "message": "", "responseList": { "id": "2", "fruit_name": "苹果", "high_price": "8.0", "low_price": "5.0", "address": "天津小白楼水果市场", "size": "2.0", "weight": "2.0", "remark": "急需...", "fruit_pic": [ "http://fruit.txunda.com/Uploads/Release/201508/55599e7514815.png", "http://fruit.txunda.com/Uploads/Release/201508/554f2dc45b526.jpg" ] } }
app端接收到的数据（原生json串）
复制代码 代码如下:
{"flag":"success","message":"","responseList":{"id":"2","fruit_name":"\u82f9\u679c","high_price":"8.0","low_price":"5.0","address":"\u5929\u6d25\u5c0f\u767d\u697c\u6c34\u679c\u5e02\u573a","size":"2.0","weight":"2.0","remark":"\u6025\u9700...","fruit_pic":["http:\/\/fruit.txunda.com\/Uploads\/Release\/201508\/55599e7514815.png","http:\/\/fruit.txunda.com\/Uploads\/Release\/201508\/554f2dc45b526.jpg"]}}
方案二：另外我们还可以通过ThinkPHP实现移动端访问自动切换主题模板，这样也可以做到移动端访问
ThinkPHP的模板主题机制，如果只是在PC，只要需修改 DEFAULT_THEME （新版模板主题默认是空，表示不启用模板主题功能）配置项就可以方便的实现多模板主题切换。
