6.  
7. class XiaoKeFuController extends Controller {
8. public function index(){
9. if (isset($_GET['echostr'])) {
10. $this->valid();
11. }else{
12. $this->responseMsg();
13. }
14. }
15.  
16. public function valid()
17. {

19. if($this->checkSignature()){
20. header('content-type:text');
21. echo $echoStr;
22. exit;
23. }else{
24. echo $echoStr.'+++'.TOKEN;
25. exit;
