tp自带的api,get请求接口html
/**
* 显示资源列表
*
* @return \think\Response
*/
public function index(Request $request)
{
// $request_method = strtolower($_SERVER['REQUEST_METHOD']);
// $return_onj = new RestRequest();
// $data = db('ShopGoods')->select();
$data = RestUtils::processRequest();
$method = $data->getMethod();
// print_r($method);
switch($method){
case 'get':
$user_list = db('ShopGoods')->limit(2)->select();
// print_r($user_list);
if($data->getHttpAccept() == 'json'){
RestUtils::sendResponse(200, json_encode($user_list), 'application/json');
}else if ($data->getHttpAccept() == 'xml') {
// using the XML_SERIALIZER Pear Package
$options = array
(
'indent' => ' ',
'addDecl' => false,
// 'rootName' => $fc->getAction(),
XML_SERIALIZER_OPTION_RETURN_RESULT => true
);
$serializer = new XML_Serializer($options);
RestUtils::sendResponse(200, $serializer->serialize($user_list), 'application/xml');
}
break;
case 'post':
$user = new User();
$user->setFirstName($data->getData()->first_name); // just for example, this should be done cleaner
// and so on...
$user->save();
break;
// etc, etc, etc...
}
}
二、 实现接口请求处理和请求处理的方法‘’apache

*/
namespace app\api\controller;
use app\api\controller\RestRequest;
//简单的class来存储request的一些信息（RestRequest），和一个提供几个静态方法的class来处理请求和响应
class RestUtils
{
//根据请求的内容类型来处理JSON或者XML，可是让咱们如今简单一点。那么，咱们处理请求的方法将会相似于这样
public static function processRequest(){
// get our verb 获取动做
$request_method = strtolower($_SERVER['REQUEST_METHOD']);
$return_obj = new RestRequest();
// we'll store our data here 在这里存储请求数据
$data = array();
switch ($request_method){
// gets are easy...
case 'get':
$data = $_GET;
break;
// so are posts
case 'post':
$data = $_POST;
break;
// here's the tricky bit...
case 'put':
// basically, we read a string from PHP's special input location,
// and then parse it out into an array via parse_str... per the PHP docs:
// Parses str as if it were the query string passed via a URL and sets
// variables in the current scope.
parse_str(file_get_contents('php://input'), $put_vars);
$data = $put_vars;
break;
case 'delete':
break;
}
// store the method
$return_obj->setMethod($request_method);
// set the raw data, so we can access it if needed (there may be
// other pieces to your requests)
$return_obj->setRequestVars($data);
if(isset($data['data'])){
// translate the JSON to an Object for use however you want
$return_obj->setData(json_decode($data['data']));
}
return $return_obj;
}
public static function sendResponse($status = 200, $body = '', $content_type = 'text/html'){
$status_header = 'HTTP/1.1 ' . $status . ' ' . RestUtils::getStatusCodeMessage($status);
// set the status
header($status_header);
// set the content type
header('Content-type: ' . $content_type);
// pages with body are easy
if($body != ''){
// send the body
echo $body;
exit;
}
// we need to create the body if none is passed
else
{
// create some body messages
$message = '';
// this is purely optional, but makes the pages a little nicer to read
// for your users. Since you won't likely send a lot of different status codes,
// this also shouldn't be too ponderous to maintain
switch($status) {

$signature = ($_SERVER['SERVER_SIGNATURE'] == '') ? $_SERVER['SERVER_SOFTWARE'] . ' Server at ' . $_SERVER['SERVER_NAME'] . ' Port ' . $_SERVER['SERVER_PORT'] : $_SERVER['SERVER_SIGNATURE'];
// this should be templatized in a real-world solution

<hr />
<address>' . $signature . '</address>
</body>
</html>';
echo $body;
exit;
}
}
public static function getStatusCodeMessage($status){
// these could be stored in a .ini file and loaded
// via parse_ini_file()... however, this will suffice
// for an example
// 这些应该被存储在一个.ini的文件中，而后经过parse_ini_file()函数来解析出来，然而这样也足够了，好比：

return (isset($codes[$status])) ? $codes[$status] : '';
