php - browsers won't display JSON content automatically -


my php (slim framework) generating json file. have checked file on json validator , fine. when enter index.html, local, angularjs main file, on browser not display json file automatically asks me whether open/save file. i'm using apache virtual host, mysql, xampp. want browser display json without saving file locally, that, when finish project , attach domain, able display json content on computer.

this php file: 

`<?php use \psr\http\message\serverrequestinterface request; use \psr\http\message\responseinterface response;  $app = new \slim\app;  // customers $app->get('/api/calendar', function (request $request, response $response) {      // echo 'calendar'; });      $sql = "select * days";      try {     // db object     $dbcalendar = new dbcalendar();     //connect     $dbcalendar = $dbcalendar->connect();      $stmt = $dbcalendar->query($sql);     $dbcalendar = $stmt->fetchall(pdo::fetch_obj);     // $dbcalendar = null;      return $response->withjson($dbcalendar);      } catch(pdoexception $e) {         $error = array('error' => array('text' => $e->getmessage()));         return $response->withjson($error,500);     } });`

ok. have changed php file (i hope correctly) according fred suggestion: 

`<?php use \psr\http\message\serverrequestinterface request; use \psr\http\message\responseinterface response;  $app = new \slim\app;  // customers $app->get('/api/calendar', function (request $request, response $response) {      // echo 'calendar'; });      $sql = "select * days";      try {     // db object     $dbcalendar = new dbcalendar();     //connect     $dbcalendar = $dbcalendar->connect();      $stmt = $dbcalendar->query($sql);     $dbcalendar = $stmt->fetchall(pdo::fetch_obj);     // $dbcalendar = null;      return $response->withjson($dbcalendar);     header('content-type: application/json');      } catch(pdoexception $e) {         $error = array('error' => array('text' => $e->getmessage()));         return $response->withjson($error,500);     } });`

but there still isn't change.

before output json string, set header, this:

header('content-type: application/json');

that should tell browser expect json content.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
