原生php实现查询接口（查询一个）

 while($row = mysqli_fetch_assoc($result)) { $data[] = $row; } $json = json_encode(array( "resultCode"=>200, "message"=>"查询成功！", "data"=>$data ),JSON_UNESCAPED_UNICODE); //转换成字符串JSON echo($json); }else{ $json = json_encode(array( "resultCode"=>200, "message"=>"暂无数据", "data"=>'' ),JSON_UNESCAPED_UNICODE); //转换成字符串JSON echo($json); } ?>
