I changed slot that connected to finish signal like this :

QByteArray bytes = R->readAll();
    QString str = QString::fromUtf8(bytes.data(), bytes.size());
    int statusCode = R->attribute(QNetworkRequest::HttpStatusCodeAttribute).toInt();
    qDebug() << QVariant(statusCode).toString();

and return 403 code it means forbidden.why?

[Axel Spoerl]

403 is what your server sends. It means that your parameters are incorrect or the server itself has (due to misconfiguration) no access to the requested resource.
Have you tried the call with postman or a browser?

[ali-aydin]

@Axel-Spoerl
Yes I tried by postman and is ok

@ali-aydin
Your platform/web server may/should have the ability to log all requests/responses to a log file? You might switch that on and see if anything helpful there?

[ali-aydin]

@JonB
OS is Windows 10 and qt 5.15.2

[JonB]

@ali-aydin Look in your web server's documentation.

@JonB
API's documentation?

I think you have to add 'Basic ' before your token when you set the Authorization header (or 'Bearer ' if you are doing bearer token auth). If things are working in Postman, check the 'Headers' tab of your request as to what is the actual value being sent for the Authorization.

[ali-aydin]

@mchinand
Bearer must be added to the token.
in postman there is no header
in authorization tab
only added token and in parameters tab is only one parameter :KalaCode
in body tab username,password and grant_type
in the qt when I want to authenticate by

QUrl url("http://localhost:594444/api/authenticate");

it returns "Hello"
but when i changing url to

QUrl url("http://localhost:594444/api/Getmojodi" );

it does not work

[mchinand]

I meant the 'Headers' tab of the Postman request:

The authorization header value above was automatically set when I added a (junk) username and password in the Auth tab:

[ali-aydin]

@mchinand
there is no problem in postman
problem is that how can we do authorization in qt?
i think yhe main problem is this

[mchinand]

Are you setting the Authorization the same in Qt as the value it is set in Postman? Your variables are 'basic_authorization' and 'token', is token just the token or is the token type prepended to it ('Basic ' or 'Bearer ')? Your variable is 'basic_authorization' but in your prior message, you mention adding 'Bearer' before the token, which auth method are you using?

[ali-aydin]

@mchinand
i'm using url.setRawHeader() for add token to url and
and adding bearer to token
i don't use any auth method
how to use that?

[mchinand]

Are you doing Basic (username/password) or Bearer Token? What method are you selecting in Postman? What is the value of your token variable, post the string but modify the actual token part.

[ali-aydin]

@mchinand
in postman i selected bearer method
and token has three part access_ token,token_type and expire_date
in qt i added "bearer" to access_token then adding this token to url.setRawHeader()

[mchinand]

What is the value of your token variable, post the string but modify the actual token part.

[ali-aydin]

@mchinand
this is token file

{
   "access_token": "1zVIXlpahfvS82xJEN2l2L7vPaUvX-AqHD5w_JmrSqHtV_hHdk6dKqdyFx6D62p1jPIcPPMdlVlsOlS4ZcoVUcsnrzTv8Ly42OLINofJYfdkVoitAQGdCzX7vYlnWBYNrxAOsMJiCdbjvONC2MftONA_hxhcsf8D3ax24buIupEkqPUoaBWUd6nx7HTx3Axo8ZdHZhM48SS68CczY-EDVUTDQSvYxv_4gQCxf_uWPuTrjTF2jwCbLfrCmhK7O_WJ07XmV-PYTj2jV7E35CpeFtx6W_FePFlhzim9qLv",
   "token_type": "bearer",
   "expires_in": 86399
}

[mchinand]

Try

QString token = <access_token from file>
token.prepend("Bearer ");
req1.setRawHeader(QByteArrayLiteral("Authorization"), token.toUtf8());

I don't think you want the 'toBase64()' that you have in your code above.

@mchinand
nop it is not ok

Check the request sent by postman and the one from your application and compare for differences.
