Is there an "example-openssl" project?

[Tzu-Lun Huang]

Hi,

I'd like to use OpenSSL to replace Libressl
but I cannot find the right way to integrate oatpp-openssl module into my oat++ project
is there any example project just like https://github.com/oatpp/example-libressl??

• AppComponent.hpp

  #include "oatpp-openssl/Config.hpp"
  #include "oatpp-openssl/server/ConnectionProvider.hpp"
...
  /**
   *  Create ConnectionProvider component which listens on the port 8443 (https)
   */
  OATPP_CREATE_COMPONENT(std::shared_ptr<oatpp::openssl::server::ConnectionProvider>, serverConnectionProvider)
  ([] {
    const char* crtFile = "cert/test_cert.crt";
    const char* pemFile = "cert/test_key.pem";

    auto config = oatpp::openssl::Config::createDefaultServerConfigShared(pemFile, crtFile);
    auto connectionProvider = oatpp::openssl::server::ConnectionProvider::createShared(config, {"localhost", 8443});
    return connectionProvider;
  }());
...

• App.cpp

  // Get connection provider component (https)
  OATPP_COMPONENT(std::shared_ptr<oatpp::openssl::server::ConnectionProvider>, connectionProvider);

And I got the following compiling errors

...
../http_server/lib/win64/liboatpp-openssl.a(ConnectionProvider.cpp.obj):ConnectionProvider.cpp:(.text$_ZN9__gnu_cxx13new_allocatorIN5oatpp7network3tcp6server18ConnectionProviderEE9constructIS5_JRKNS2_7AddressERbEEEvPT_DpOT0_[_ZN9__gnu_cxx13new_allocatorIN5oatpp7network3tcp6server18ConnectionProviderEE9constructIS5_JRKNS2_7AddressERbEEEvPT_DpOT0_]+0x5c): undefined reference to `oatpp::network::tcp::server::ConnectionProvider::ConnectionProvider(oatpp::network::Address const&, bool)'

...

thank you :)

Update:

I solved my problem by switching the order in the "CMakeLists.txt"

    ${oatpp-openssl}
    ${oatpp}

But when I start my server, the error message is:

terminate called after throwing an instance of 'std::runtime_error'
  what():  [oatpp::openssl::configurer::CertificateChainFile::configure()]: Error. Call to 'SSL_CTX_use_certificate_chain_file' failed.

I use the certificate keys in the https://github.com/oatpp/example-libressl/tree/master/cert
is that OK?

[Tzu-Lun Huang]

Oops!

I made a typo for my certificate filename

I think this ticket can be closed

I'm using MSYS2 on windows environment
So the OpenSSL::Crypto & OpenSSL::SSL are from MSYS2 package server
And I use MinGW to build the oatpp-openssl related libraries for my project

This is my CMakeLists.txt

cmake_minimum_required(VERSION 3.14)
