getResponseHeader doesn't return all fields

niqt

Hi,
i'm using var xhr = new XMLHttpRequest(); to do a post request, when i read the response header i don't find all the fields (i.e. Autohorization). Using the c++ classes i can read all the fields. What's the problem with js function?

@niqt
you need to be more specific.

i assume you are using QML / QQmlEngine? Or do you use QtScript?
Whats the url you are posting to? A custom web server/service?
Show some code please, maybe you are reading the response too early.

My code it's in js file and i call it from qml

function requestRestUser(verb, endpoint, obj, cb) {
    var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function() {

        if(xhr.readyState === XMLHttpRequest.DONE) {
            if(cb) {
                if (xhr.status == "200") {
                    console.log("header" + xhr.getAllResponseHeaders());
                    cb(true, xhr.getResponseHeader('Authorization'));
                } else if (xhr.status == "400" || xhr.status == "401") {
                    cb(false, "");
                }
            }
        }
    }
    xhr.open(verb, endpoint);
    xhr.setRequestHeader('Content-Type', 'application/json');
    var data = (obj)?JSON.stringify(obj):''
    xhr.send(data)
}

I have 200 code, but the xhr.getResponseHeader('Authorization') is empty (if i do the same with c++ i got it). The remote server ia java rest server.

@niqt
even though QML's XMLHttpRequest object doesn't enforce the same origin policy, it may be still related to such or similar.
In case i am right and it's a CORS related issue you might want to try to add the following:

xhr.setRequestHeader('Access-Control-Expose-Headers', 'Authorization');

Can you sniff the HTTP requests and corresponding responses done with XMLHttpRequest and also with QNetworkAccessManager and post them here? For sniffing you can use a tool like Wireshark for example.

Maybe your Java webservice doesn't like something about the request sent via XMLHttpRequest. But this should be clearly seen when comparing the Request- and Response-Headers.

Can be a problem https?

@niqt said in getResponseHeader doesn't return all fields:

Can be a problem https?

shouldn't be, since the data after all should be the same.

From today it's ok and i don't know why.
