1、在控制器页面：

<?PHP
//本类由系统自动生成，仅供测试用途
namespaceHome\Controller;
useThink\Controller\RestController;
classIndexControllerextendsRestController{
//显示页面
publicfunctionindex(){
//print_r($this->_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;
}
}
publicfunctionsel($name){
//print_r($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($name,'id');//获取市idgetFieldBy根据字段查询并返回某个字段的值例如，getFieldByName
//print_r($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：

<?PHP
returnarray(
//'配置项'=>'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'),),);
?>
