I’m trying to create an url shortener app using google’s url shortener api (https://developers.google.com/url-shortener/v1/getting_started#shorten). The problem is that I get a bad request.
Here is the error:
Error: Error downloading https://www.googleapis.com/urlshortener/v1/url – server replied: Bad Request
What did I do wrong?
Here is the code:
void MainWindow::ppp(QString longurl)
{
QNetworkAccessManager* manager = new QNetworkAccessManager(this);
connect(manager, SIGNAL(finished(QNetworkReply *)), this, SLOT(replyFinished(QNetworkReply *)));
QUrl url = QUrl("https://www.googleapis.com/urlshortener/v1/url");
QNetworkRequest request(url);
request.setHeader(request.ContentTypeHeader,"application/json");
QByteArray postData;
postData.append("longUrl=");
postData.append(longurl);
manager->post(request,postData);
}
void MainWindow::replyFinished(QNetworkReply *reply)
{
if(reply->error() != QNetworkReply::NoError)
{
ui->textBrowser->setText("Error: " + reply->errorString());
}
else
{
QByteArray responseData = reply->readAll();
QString qstr(responseData);
ui->textBrowser->setText(qstr);
}
}
