How to download using QHttp?

[ChrisW67]

I have used QHttp for downloading it, now the file is being downloaded , and saved in the local disk, But i just want to read that file, storing it in a variable, and not saving it as a file in local hard disk. How to perform this with QHttp??

Even if you persist in using the obsolete class you can use QHttp::readAll() to put the data into a QByteArray (either bit-by-bit using in response to readyRead(), or all at once in response to finished()). That is, use exactly the same method as used in the HTTP Example. This information really easy to find if you read the docs and work through the examples (until you understand them).

How to read the whole file at once using readAll()?

[ChrisW67]

Wait until the QNetworkReply::finished() or QNetworkAccessManager::finished() signal is emitted and then call readAll(). If you are still using QHttp then you can work out the equivalent for yourself.

If your file is large, or you don't know its size, then trying to hold the whole thing in memory might be a mistake.
