POST request from curl example

[SGaist]

Did you check the server logs ?
Did you connect the reply errorOccured and sslErrors signals ?

[Damian7546]

@SGaist working! Tahnks for help.

[SGaist]

What did you do to fix the problem ?

[Damian7546]

@SGaist In Ubuntu (where I developing my app) I had a problem with ssl, and below solution fixed my problem:
https://forum.qt.io/topic/144102/qsslsocket-failure-from-online-installer-version-ubuntu/8

And added to *.pro file:

LIBS += -L/opt/openssl-1.1.1q -lcrypto 
LIBS += -L/opt/openssl-1.1.1q -lssl

I have no idea how to run it on my destinatiom machine based on Debian System ....

To generate file to my destination machine I use CQtDeployer , which one generate below directories:

but inside I do not see any files related with ssl.

@SGaist What can I do ?

[SGaist]

@Damian7546 you don't . You have to deploy the libraries along with your application.

[Damian7546]

@SGaist hmm... but I do not know how....

[JonB]

@Damian7546 Start by looking at the alternatives mentioned in https://forum.qt.io/topic/154740/where-is-linuxdeployqt

[Damian7546]

@JonB I Use CQtDeployer.
I am currently using two options:
cqtdeployer -bin -qmlDir
To add libs from my .pro file :
LIBS += -L/opt/openssl-1.1.1q -lcrypto
LIBS += -L/opt/openssl-1.1.1q -lssl

Which one options I should add ? -libDir or -extraLibs ?

[Damian7546]

@JonB @SGaist

I copied dictionary with ssl library to my qt project location:

.../Lib/openssl-1.1.1q

And changed the *.pro file to:

LIBS += -L$$PWD/Lib/openssl-1.1.1q/ -lcrypto
LIBS += -L$$PWD/Lib/openssl-1.1.1q/ -lssl

Application works , when is runnig form qt creator . But when I run without qt creator it doesnt work ...

[JonB]

@Damian7546
Assuming by "doesnt work" you mean you are told it cannot find the OpenSSL shared libraries at runtime.

Then the implication is that the environment/search path is somehow different from Creator than without. E.g. check your LD_LIBRARY_PATH.

From a terminal try running ldd on your executable. Does that show it requiring certain *.so files which cannot be found?

I believe the OpenSSL runtime provides some runtime openssl.so (or whatever name) file(s). Find these.

I copied dictionary with ssl library to my qt project location:

That may be enough for linking, but I don't think it is for locating the .so files at runtime under Linux. Unless they are picked up off the RPATH which was linked into the program.

[Damian7546]

@JonB Now work!

I copied from: ..../Lib/openssl-1.1.1q below files:
libcrypto.so
libcrypto.so.1.1
libssl.so
libssl.so.1.1

to my deployed application

It look like by default, an SSL library are dynamically loads any installed OpenSSL library at run-time.

[SGaist]

Yes, by default Qt builds dlopens OpenSSL.
