how to get Login and access data from https://10.201.58.88:2342/kirk/1.0/hosts/0/physicaldrives

/ QString USER_AGENT = "Mozilla/5.0";

QUrl serviceURL("https://10.201.58.87:2342/kirk/1.0/session");
QNetworkRequest request(serviceURL);


request.setRawHeader("Host","10.201.58.88:2342");

qDebug() << "post" << reply;
qDebug() << "get" << manager.get(request);
QByteArray response = reply->readAll();

qDebug() << " response" << response;
loop.exec();
I have tried this but getting

post QNetworkReplyHttpImpl(0x2386790)
get QNetworkReplyHttpImpl(0x365a50)
response ""
error "Unknown error"

Depends entirely on the server application. You'll have to find/read/digest the server API documentation to determine how to properly authenticate your requests. Could be simple authentication using HTTP basic authentication (i.e. Authorization HTTP header), or something more complex like OAuth2, etc.

Your code snippet seems to miss the line where you actually run the nested event loop.

QEventLoop loop;

QUrl serviceURL;
serviceURL.setUrl("https://10.201.58.87:2342/kirk/1.0/session");

QNetworkRequest request(serviceURL);
QNetworkAccessManager manager;
QNetworkReply* reply;


request.setRawHeader("Host","10.201.58.88:2342");
request.setRawHeader("host_key", "824D10304899A");
request.setRawHeader("User-Agent", "Mozilla/Firefox ");
request.setRawHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
request.setRawHeader("Accept-Language", "en-US,en;q=0.5");
request.setRawHeader("Accept-Encoding", " gzip, deflate");
request.setRawHeader("Referer", "https://10.201.58.87:2342/ui/core/index.html");
request.setRawHeader("Content-Type", "application/json");
request.setHeader(QNetworkRequest::ContentTypeHead er,"application/x-www-form-urlencoded;charset=UTF-8");
request.setRawHeader("Content-Length", "46");
request.setRawHeader("Connection", "keep-alive");

QByteArray usr = "root";
QByteArray pwd = "asd@123";
QByteArray jsonString = "{\"uname\":\"" +usr+"\", \"pwd\":\""+pwd+"\"}";

connect(&manager, SIGNAL(finished(QNetworkReply*)), &loop, SLOT(quit()));
reply = manager.post(request, jsonString);

qDebug() << "post" << reply;
qDebug() << "get" << manager.get(request);

QByteArray response = reply->readAll();
qDebug() << " response" << response;

QUrl Url("https://10.201.58.87:2342/kirk/1.0/hosts/0" );
reply = manager.get(QNetworkRequest(Url));
reply->ignoreSslErrors();
loop.exec();

qDebug() << "error" <<reply->errorString();
QString strReply = (QString)reply->readAll();


//parse json
qDebug() << "URL Reply:" << strReply;

return 1;



got this :
post QNetworkReplyHttpImpl(0x3f60a40)
get QNetworkReplyHttpImpl(0x3f60b80)
response ""
error "Unknown error"
URL Reply: ""
error "Unknown error"
URL Reply: ""

Hint: what is wrong here (taken directly from your code)?



reply = manager.post(request, jsonString);

QByteArray response = reply->readAll();

loop.exec();
