I'm doing an API with Slim Framework and when I test the answer with Postman everything works fine, however when I put it on the server and tried to make an ajax call to test I got the error below.
Failed to load link : Redirect from ' link ' to ' link 'has been blocked by CORS policy: No' Access-Control-Allow-Origin 'header is present on the requested resource. Origin ' link ' is therefore not allowed access.
Here is the method I use to return Json:
public function withCustomJson($meta = null, $data = null)
{
if (isset($data)) {
$finalResponse['data'] = $data;
}
$finalResponse['meta'] = array(
'status' => (isset($meta['status']) ? $meta['status'] : null),
'message' => (isset($meta['message']) ? mb_convert_encoding($meta['message'], "UTF-8", "auto") : null)
);
$response = $this->withBody(new Body(fopen('php://temp', 'r+')));
$response->body->write($json = json_encode($finalResponse));
// Ensure that the json encoding passed successfully
if ($json === false) {
throw new \RuntimeException(json_last_error_msg(), json_last_error());
}
//Allowing CORS as Slim docs states
$responseWithJson = $response->withHeader('Content-Type', 'application/json;charset=utf-8')
->withHeader('Access-Control-Allow-Origin', '*')
->withHeader('Access-Control-Allow-Headers', 'X-Requested-With, Content-Type, Accept, Origin, Authorization')
->withHeader('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS');
if (isset($meta['codStatus'])) {
return $responseWithJson->withStatus($meta['codStatus']);
}
return $responseWithJson;
}
And here's my Ajax call:
<script type="text/javascript">
try {
$.ajax({
url: 'https://api.mydomain.net/usuario/autenticar',
type: 'GET',
dataType: 'json',
data: {
xAuthClienteID:'2',
xAuthChaveApi: '3851b1ae73ca0ca6e3c24a0256a80ace',
login: 'admin',
senha: 'teste'
},
ContentType: 'application/json',
success: function(response){
console.log(response);
},
error: function(err){
console.log(err);
}
});
}
catch(err) {
alert(err);
}
</script>
It seems that the problem is that CORS requests are not active on my server, so I took a look at the Slim documentation on how to activate and applied to my method of returning Json, but I still get the error. Where am I going wrong?
