QUrl encoding problem (Qt 5.0.2)

Hey All,
I've been banging my head against the wall with this issue for hours, hoping someone here has a workaround!Is there a way to set a QUrl without it being 'smart' and automatically messing with the URL encoding? This default behaviour makes it impossible to form a valid request.
I am using a rest API that requires me to POST to a URL which contains a path+filename. Here is my attempt to upload a file named "first;second.jpg"
I construct a QByteArray that has the encoding I want, and print it out:
@QByteArray rawUrl;
...
qDebug() << "as QByteArray" << rawUrl;OUTPUT: as QByteArray "https://www.example.com/0/io/init_upload/%2FDesktop Uploads%2Fsemicolons%2Ffirst%3Bsecond.jpg"@
As you can see the semicolon is nicely encoded as a %3B
Then I construct a QUrl from it:
@QUrl url(rawUrl); // using url.setUrl(rawUrl, QUrl::StrictMode) has same effect
Q_ASSERT(url.isValid()); // succeeds
qDebug() << "as QUrl " << url.toEncoded(QUrl::FullyEncoded);OUTPUT: as QUrl "https://www.example.com/0/io/init_upload/%2FDesktop Uploads%2Fsemicolons%2Ffirst;second.jpg"@
As you can see the semicolon was decoded. When I create a QNetworkRequest with this URL, and observe what it is doing on the network with Charles Proxy I can see the request being made exactly matches that debug output.
The expected behaviour is that the semicolon remains as %3B
(This request fails because ; is just like ? or & and cuts the URL short as if arguments were to follow, and they arent. ugh.)

(on a related note, I had to URL encode this entire post for it to show up correctly. Looks like this forum automagically decodes things as well! haha dang.)

The forum ate this post, here is the RAW text: http://codepad.org/ykMXCtXN

To paraphrase.
Is it possible to create a QUrl that contains %3B (percent-three-be) in it? Not a semicolon, but that exact sequence of three characters.
I cannot find a way to do this.

@
QUrl url;
url.setScheme("https");
url.setHost("www.example.com");
url.setEncodedPath("0/io/init_upload/%2FDesktop%20Uploads%2Fsemicolons%2Ffirst%3Bsecond.jpg");
qDebug() << url.toEncoded();url = QUrl::fromEncoded("https://www.example.com/0/io/init_upload/%2FDesktop Uploads%2Fsemicolons%2Ffirst%3Bsecond.jpg");
qDebug() << url.toEncoded();
@
Outputs:
@
"https://www.example.com/0/io/init_upload/%2FDesktop Uploads%2Fsemicolons%2Ffirst%3Bsecond.jpg"
"https://www.example.com/0/io/init_upload/%2FDesktop Uploads%2Fsemicolons%2Ffirst%3Bsecond.jpg"

That looks sound, but unfortunately setEncodedPath() doesn't seem to exist in QT 5.0.2 anymore :(
@qurl.h
...
QT_DEPRECATED void setEncodedPath(const QByteArray &value)
{ setPath(fromEncodedComponent_helper(value)); }
...
@Is there a way to access the deprecated function, or something new in 5 that has replaced it?
-
Hmmm, nice change of behaviour. I'll have to give it some thought.
-
This is still an issue with no apparent way to work around.
How should I got about filing a bug / making a request?

Hi,
Even I am facing similar issue, in my case colon (:) is getting decoded by default.
I found this ticket https://bugreports.qt-project.org/browse/QTBUG-31660 logged for this issue, but it does not say anything about when the fix will be available.
