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

查询单个果品详细信息
/**

*/
public function getMyReleaseInfo(){
//检查是否通过post方法得到数据
checkdataPost('id');
$where['id'] = $_POST['id'];

//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'] = <a href="https://www.baidu.com/s?wd=array_filter&tn=44039180_cpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1d9ryc1uyckrj-WmHN9Pj9b0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EPWbsnjm1PWcdnW04nWmLP1mY" target="_blank" class="-highlight">array_filter</a>(explode(',', $releaseInfo['fruit_pic']));

//为图片添加存储路径

}
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）
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"]}}
