Problem with HttpClient and API request

API Discussion
#1

Hi there,

I’m trying to get every realm by requesting the wow’s API.

My code :

public function getRealms()
{
    $response = $this->client->request(
        'GET',
        'https://eu.api.blizzard.com/data/wow/realm/index',
        [
            'auth_bearer' => $this->auth_bearer,
            'headers' => [
                'Cache-Control' => 'no-cache',
                'Connection' => 'keep-alive'
            ],
            'query' => [
                'namespace' => 'dynamic-eu',
                'locale' => 'en_EN'
            ]
        ]
    );

    $statusCode = $response->getStatusCode();
    dump($statusCode); // show "200"

    $contentType = $response->getHeaders()['content-type'][0];
    dump($contentType); // show "application/json;charset=UTF-8"

    $contentArray = $response->toArray(); // <== TIMEOUT ERROR 
    dump($contentArray); 

    return $contentArray;
}

And after default timeout I get this error

Idle timeout reached for “https:// eu.api.blizzard .com/data/wow/realm/index?namespace=dynamic-eu&locale=en_EN”.

I do not understand why I’m getting this error while I’m getting a 200 success code. I’m using HttpClient which is embedded with Symfony framework. And my function is on a service class.

Any ideas ?

EDIT : I’m testing every request with Postman. And it works on Postman. And I tested with more items on another API (500+ items), this function works fine.

My guess it has something to do with the content you are expecting. On top-level this is not an array, but an object containing a property (“realms”) which is an array.
I am not familiar with Symfony or its HttpClient. But most examples will call $response->getContent() before proceeding.

I would try changing the Connection header to close instead of keep-alive. I remember people had some trouble with the API server not closing the connection properly before.

Hi ! Thank’s for the help ! I tried with getContent() before that and it leads to the same trouble.

I changed my code to be sure that it’s neither the dump() nor the code after the return’s function that is causing this.

public function getRealms()
{
    $response = $this->client->request(
        'GET',
        'https://eu.api.blizzard.com/data/wow/realm/index',
        [
            'auth_bearer' => $this->auth_bearer,
            'headers' => [
                'Cache-Control' => 'no-cache',
                'Connection' => 'keep-alive'
            ],
            'query' => [
                'namespace' => 'dynamic-eu',
                'locale' => 'fr_FR'
            ]
        ]
    );

    $statusCode = $response->getStatusCode();
    $contentType = $response->getHeaders()['content-type'][0];
    $contentArray = $response->getContent();
    echo "ok";
    die;
    return $contentArray;
}

Unfortunately the echo never comes and I get the same error.

EDIT: I tried to replace keep-alive by close but nothing changed and I tried to remove it. Same :frowning:

I just wanna make sure I’m following, you do receive the response headers with a 200 status. I mean this line is working:

dump($contentType); // show "application/json;charset=UTF-8"

however it stops on this line until it times out ?

$contentArray = $response->toArray(); // <== TIMEOUT ERROR

or you receive the timeout error just after the 200 is received ?

#6

The timeout comes when I try to do a getContent() or a toArray();

Lines dumping contentType and statusCode are working and they return
statusCode : 200
contentType : application/json;charset=UTF-8

EDIT: Other requests work, if I try to call
https:// eu.api.blizzard. com/data/wow/realm/hyjal?namespace=dynamic-eu&locale=en-EN
I get my response. So I thought it was a “length/weight” problem, but when I try with larger request on others API (500+ items) it works too.

#7

Interesting, I don’t think that is the problem but just in case, can you add the request header 'Accept' => 'application/json' ?

#8

Just tried, but no :frowning:

#9

Ok, one last try :roll_eyes:. Set the header 'Accept-Encoding' => 'gzip'.

#10

Hmm I have not tried this one yet, but it did nothing. I’m up for any ideas, even crazy ones, I do not understand why THIS call is crashing while responding 200.
And it is good on Postman, It must come from these getContent and toArray methods. I want to try another lib to make http requests like Guzzle but I can’t stand not understanding this one.

Unfortunately I gotta go back to work now, consider joining the Community Discord Server there are a lot of nice people over there who can help you.
And I’ll try to help you more later if you still need. Good luck.

Thank you very much Schiller, I’ll join the Discord, nice tip. Have a nice day !

EDIT :

Ok, we solved this by replacing HttpClient and adding the Curl layer, CurlHttpClient which is normaly embedded with HttpClient. I still don’t know why HttpClient was not enough for this request.

public function __construct()
{
    // $this->client = HttpClient::create();
    $this->client = new CurlHttpClient();
    $this->auth_bearer = $this->getAuthBearer();
}

thx Schiller !

Had the same problem with HttpClient after updating php and symfony.
At the end this was a problem with the php.ini setting:

default_socket_timeout = -1

somehow the HttpClient seems not to like the default value “-1”

I changed it to “60” and everything was OK.
This solved my problem.
