I'm building a website with Azure authentication using MS Graph. As you can see below I want to login and get my own data as well as my managers which is working fine, however the issue begins when I want to select the photo.
$graph = new Graph();
$graph->setAccessToken($accessToken->getToken());
$user = $graph->createRequest('GET', '/me?$expand=manager($levels=1;$select=displayName,givenName,surname,mail)&$select=displayName,givenName,surname,mail&$count=true')
->addHeaders(array("Content-Type" => "application/json"))
->setReturnType(Model\User::class)
->execute();
$photo = $graph->createRequest('GET', '/me/photo/$value')
->addHeaders(array("Content-Type" => "image/jpeg"))
->execute();
$photo = $photo->getRawBody();
$avatar = 'data:image/jpeg;base64,'.base64_encode($photo).'';
When a user does not have a profile photo set it will return a 404 Not Found which is ok, but I don't want my script to stop if there is no photo. What I want is something like this:
if($photo->getStatus(404)){
$avatar = null;
}
else{
$photo = $photo->getRawBody();
$avatar = 'data:image/jpeg;base64,'.base64_encode($photo).'';
}
If there is no photo I want to set $avatar to null instead of getting the following error:
Thanks in advance!

CodePudding user response:
Try to catch the exact exception the error is client exception of 404 status code try to catch it directly and catch its response. Also I have never heard of function $e->getResponseBody()
it should be $e->getResponse()
as given in guzzle docs. You can take more reference from this answer
public function callback(Request $request)
{
// Validate state
// ...
// Initialize the OAuth client
try {
// Make the token request
// ...
// Define user details and manager details
// ...
}
catch(\GuzzleHttp\Exception\ClientException $e){
if($e->hasResponse()){
if ($e->getResponse()->getStatusCode() == '404'){
$avatar = null;
return redirect('/')
->with('error', 'Error requesting access token')
->with('errorDetail', json_encode($e->getResponse()));
}
}

$avatar = null;

CodePudding user response:
I am not familiar with the microsoft graph api, but a basic PHP Try - Catch block should do the trick here.
https://www.php.net/manual/en/language.exceptions.php
Try to fetch the image -> in case an exception occurs set $avatar to null
CodePudding user response:
Please use the try/catch block. This serves the purpose of handling errors at your end rather than the server handling them for you.
Also I have noticed '/me/photo/$value'
this will not replace $value using single quotes properly. Please use double quotes here "/me/photo/$value"
.
use Exception; //import right after namespace
try {
$photo = $graph->createRequest('GET', '/me/photo/$value')
->addHeaders(array("Content-Type" => "image/jpeg"))
->execute();
$photo = $photo->getRawBody();
$avatar = 'data:image/jpeg;base64,'.base64_encode($photo).'';
} catch (Exception $e) {
//in-case of error
$avatar = null;
}
