Tp3.2 RESTFul 根据地区查询生成xml、html、json的Api接口的天气信息

1、在控制器页面：

_method);die;        $Name = $_GET['data'];        if(!preg_match("/^[A-Za-z]+$/",$Name)){            echo "输入有误";die;        }        if(__EXT__ == ''){            $type="html";        }else{            $type=__EXT__;        }        switch ($this->_method){               case 'get': // get请求处理代码                      if (__EXT__ == 'html'){                $html = $this->sel($Name);                $this->response($html,'html');                //echo "html";            }elseif(__EXT__  == 'xml'){                 $xml = $this->sel($Name);                $this->response($xml,'xml');                            }elseif(__EXT__  == 'json'){                $json = $this->sel($Name);                $this->response($json,'json');            }                       break;            case 'put': // put请求处理代码                      break;                  case 'post': // post请求处理代码                       break;             }       }    public function sel($name){        //print_r($name);die;        $sheng = M('sheng');  //实例化表        $city = M('city');        $xian = M('xian');        if($name=="china"){            $data=$sheng->select();            return $data;        }else{            $s_id =$sheng->getfieldbypyname($name,'id');  //获取查询省id            //print_r($s_id);die;            //判断获取省id是否为空，如果不为空查询获取省的下级的关联id的相关数据            if(!$s_id==""){                $c_id['p_id']=$s_id;                    $datas = $city->where($c_id)->select();                 //print_r($datas);die;                return $datas;            }else{                $city_id =$city->getfieldbypyname($name,'id'); //获取市id  getFieldBy 根据字段查询并返回某个字段的值 例如，getFieldByName                 //print_r($city_id);die;                if(!$city_id==""){                    $x_id['p_id']=$city_id;                    $data1 = $xian->where($x_id)->select();                    //print_r($data1);                    return $data1;                }else{                    $xian_id = $city_id =$xian->getfieldbypyname($name,'id');                    //print_r($xian_id);die;                    if(!$xian_id==""){                        $cx_id['id']=$xian_id;                        //print_r($cx_id);die;                        $data2 = $xian->where($cx_id)->select();                        //print_r($data2);die;                        return $data2;                    }else{                        echo "没有该地区！";                    }                }            }        }    }}

2、配置文件：

'配置值'/* 数据库设置 */    'DB_TYPE'               => 'mysql',     // 数据库类型    'DB_HOST'               => '127.0.0.1', // 服务器地址    'DB_NAME'               => 'news',          // 数据库名    'DB_USER'               => 'root',      // 用户名    'DB_PWD'                => '',          // 密码    'DB_PORT'               => '3306',        // 端口    'URL_ROUTER_ON'   => true, //开启路由    'URL_ROUTE_RULES'=>array(             'Index/:data' => array('Index/index', 'status=1'),    ),);?>
