Talk:Creating an HTTP network request in Qt

From Wiki
Jump to: navigation, search

Creating an HTTP network request is one of the baseline tasks required of most developers in this day and age. This article spells out in clear, yet concise steps, the information required to accomplish this task.

In addition to a relevant list of preconditions, this article steps the reader through the relevant coding sections in a well thought out manner. The frequent line level coding documentation was useful for this reader (and better than his own). In the example code, the author demonstrates two alternate ways of using the reply read from the network, both of which will be helpful to developers that are new to QT.

This code goes against QT's own documentation

From the Article:

   // We receive ownership of the reply object
   // and therefore need to handle deletion.
   delete reply;

QT documentation (for signal finished()):

   Note: Do not delete the reply object in the slot connected to this signal. Use deleteLater().

Suggest changing the code to reply.deleteLater();

This code:

   QByteArray bytes = reply.readAll();  // bytes 
   QString string(bytes); // string

is wrong. Use

   QString string = QString::fromXXX(bytes); 

where XXX is the encoding of the data in the bytearray, ie fromUtf8(...)

It would be really helpful to have Qt Code double-checked by someone from Qt Dev, or at the very least allow editing of this kind of articles. Wrong information is worse than no information.

Patxitron - The C++ is wrong

In adition to the errors pointed by -apoenitz2, in the MyHttpEngine::finishedSlot since reply is a pointer to QNetworkReply the line

QByteArray bytes = reply.readAll();  // bytes 

is wrong. It should be

QByteArray bytes = reply->readAll();  // bytes 

Best regards

Hamishwillee - Thanks Patxitron

I've fixed up your error, as it is basic C++. Didn't fix the other stuff. This is a wiki, so if you're absolutely sure of yourself then you can change the article to fix it yourself.
