Добрый день. Никак не соображу как правильно оформить POST запрос для того чтобы загрузить изображение. Искал по сети, перебрал несколько вариантов, пока все время выдает в ответ на запрос "(#324) Requires upload file".
Вот авторизация:
ui->webView->load(QUrl("https://www.facebook.com/dialog/oauth?"
"client_id=XXXXXXXXXX&"
"display=popup&"
"response_type=token&"
"scope=user_status,user_photos,publish_actions&"
"redirect_uri=https://www.facebook.com/connect/login_success.html"));
Вот какие варианты перебрал
I.
QString uploadUrl = "https://graph.facebook.com/me/photos?access_token=" +
accessToken;
QString photoPath = QCoreApplication::applicationDirPath() + "/image_example.png";
QFileInfo fileInfo(photoPath);
QFile file(photoPath);
QString comment = "User provided message";
QString bound="---------------------------17673466415141";
QByteArray data;
data.append("--" + bound + "\r\n");
data.append("Content-Disposition: form-data; name=\"access_token\"\r\n\r\n");
data.append(accessToken + "\r\n");
data.append("--" + bound + "\r\n");
data.append("Content-Disposition: form-data; name=\"source\"; filename=\""
+ file.fileName()+"\"\r\n");
data.append("Content-Type: image/" + fileInfo.suffix().toLower() + "\r\n\r\n");
data.append(file.readAll());
data.append("\r\n");
data.append("--" + bound + "\r\n");
data.append("Content-Disposition: form-data; name=\"message\"\r\n\r\n");
data.append(comment);
data.append("--" + bound + "\r\n");
QNetworkRequest request(uploadUrl);
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("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7");
request.setRawHeader("Keep-Alive", "300");
request.setRawHeader("Content-Type",
QString("multipart/form-data; boundary=" + bound).toLatin1());
request.setRawHeader("Content-Length", QString(data.size()).toLatin1());
QNetworkAccessManager * manager = new QNetworkAccessManager(this);
QNetworkReply * reply = manager->post(request, data);
QEventLoop wait;
connect(manager, SIGNAL(finished(QNetworkReply*)), &wait, SLOT(quit()));
connect(manager, SIGNAL(finished(QNetworkReply*)), manager, SLOT(deleteLater()));
QTimer::singleShot(10000, &wait, SLOT(quit()));
wait.exec();
QByteArray answer = reply->readAll();
reply->deleteLater();
qDebug() << answer;
II
QString uploadUrl = "https://graph.facebook.com/me/photos?access_token=" +
accessToken;
QString photoPath = QCoreApplication::applicationDirPath() + "/image_example.png";
QFileInfo fileInfo(photoPath);
QFile file(photoPath);
QPixmap pixmap;
pixmap.load(photoPath);
QByteArray data;
QBuffer buffer(&data);
buffer.open(QIODevice::ReadWrite);
pixmap.save(&buffer, "png");
buffer.close();
QHttpMultiPart * multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);
QHttpPart imagePart;
imagePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("image/png"));
imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"source\"; filename=\""+ file.fileName()));
imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"message\""));
imagePart.setBody(data);
multiPart->append(imagePart);
QNetworkAccessManager * manager = new QNetworkAccessManager(this);
QNetworkReply * reply = manager->post(request, multiPart);
QEventLoop wait;
connect(manager, SIGNAL(finished(QNetworkReply*)), &wait, SLOT(quit()));
connect(manager, SIGNAL(finished(QNetworkReply*)), manager, SLOT(deleteLater()));
QTimer::singleShot(10000, &wait, SLOT(quit()));
wait.exec();
QByteArray answer = reply->readAll();
reply->deleteLater();
qDebug() << answer;
Буду рад любой помощи. Спасибо
