qt class lib rest api

Mr.alaa

Hi everyboy i wanna to make class library to rest api with model like c# what i mean that i have created shared class lib and add my methods there with add data , update and delete .... and created my functions for that i need to make mdel with all properties wherei can p[ass json result to theese items or properties i use qt and c++

my mainclass.h method is

//Method to genrate token
std::string  GenerateToken( QString& Uname,  QString& password);

my main .cpp

std::string MicrosoftGraph::GenerateToken( QString& Uname, QString& password)
{
QNetworkAccessManager * manager = new QNetworkAccessManager();
QByteArray jsonDocument("{}");

QUrl url("https://google.com/oauth2/token");
QNetworkRequest request(url);
request.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");

QUrlQuery params;
params.addQueryItem("username", Uname);
params.addQueryItem("password", password);

  QNetworkReply* reply =  manager->post(request, params.query().toUtf8());

    std::cout << "Ok, Server response : " << reply << std::endl;
    std::string token = "tahnks";

    return token;

}

what i need as i mentioned to get return to variable whuch declared like model in c#

for example in header file

namespace getdata {

struct Body {
      QString token;
      QString msg;
  };

}

Hi,

First thing: you are leaking QNetworkAccessManager objects for each call to GenerateToken.

Qt is asynchronous so you want to have a slot or a lambda to parse the answer.

Not knowing what you want to do with that structure, its not possible to give further advices.

@SGaist Thanks for response what i try to do is try to make c++ library to get and post api data and return result which comes from json . json contain many value which i try to return all values like models in c# then i will use it in my c# application

@SGaist I try to make c++ library

where i can call functions to excute apsi

to get ot post data and return resul

Then you mean you want a synchronous behaviour ?
If so, you can use QEventLoop to "block the execution flow". Do not forget to take into account error management.
