qt6.6 network get "The credentials were not recognized "

[lingxing]

@jsulm it's a http request。this is a login case。user pass username and password to login。
most people it work fine，but a few man it work error。

@lingxing said in qt6.6 network get "The credentials were not recognized ":

user pass username and password to login

Then you will need to show your code so that others can see how your assembling the GET request with credentials.

As @jsulm says. Show one example of username/password which works and one which does not.

qtnetwork:QHttpThreadDelegate log

Debug: QHttpThreadDelegate::startRequest() thread= 0x13dc ((null):0, (null))
Debug: QHttpThreadDelegate::finishedWithErrorSlot() thread= 0x13dc error= QNetworkReply::UnknownNetworkError "The credentials were not recognized / Invalid argument" ((null):0, (null))

when success，the log is ：
Debug: QHttpThreadDelegate::startRequest() thread= 0x25f4 ((null):0, (null))

@lingxing It would be helpful if you would provide information asked (like code or example of username/password)...

something，the problem not happen on sdk qt6.4.3。
before i use qt6.4.3 for a long tome，when i update sdk to 6.6.0，meet the problem。

[lingxing]

sample code below
link text

[lingxing]

the situation is blow：

• the error occur on a few compture，and always happen。the error happen don't relate to which url i request。every 'https request' will lead to the error。

@lingxing This is different from what you said previously. What/how have you set up SSL?

[lingxing]

@JonB

i only use this code （getrequest.cpp)，no other code to set up ssl。
do i neet to set up ssl by myself？

[jsulm]

@lingxing Please post code as text, not pictures.
What @JonB probably means is whether you provide OpenSSL libs together with your application. You can find out if you set QT_DEBUG_PLUGINS env variable to one in the terminal where you start your app and check its output. See https://doc.qt.io/qt-6/debug.html
Also see https://doc.qt.io/qt-5/windows-requirements.html

@lingxing
As @jsulm has said. I don't doubt that your SSL code is correct. You have runtime behaviour which might indicate a problem with SSL/https, you need to check that your runtime OpenSSL is installed and acting correctly.

[lingxing]

@jsulm yes，i have libcrypto-3-x64.dll with my application together。because one sdk depend it。 this make effect for my qt application?

[jsulm]

@lingxing As far as I know there are two libraries needed for SSL support: libssl and libcrypto

[lingxing]

i will try 3ks

[JoeCFD]

@lingxing Are you using openssl-3 now?

[lingxing]

i think it may be effect for me。the question can close now。if has problem, i will ask again。thanks for all of you。
