How to use OpenSSL in POCO C++ library correctly

Question

According to the Specification in POCO assistant:

Initialize the NetSSL library, as well as the underlying OpenSSL libraries, by calling Poco::Crypt

Answer 1

Let's take Net/samples/httpget as an example, let's copy httpget/ as a new httpsget directory:

1. open Makefile, add "PocoNetSSL" to target_libs
2. replace 'HTTPClientSession' with 'HTTPSClientSession'
3. you need to create Poco::Net::Context for SSL use
4. replace 'HTTPClientSession session(uri.getHost(), uri.getPort());' with following two lines:

const Context::Ptr context = new Context(Context::CLIENT_USE, "", "", "", Context::VERIFY_NONE, 9, false, "ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH");
HTTPSClientSession session(uri.getHost(), uri.getPort(), context);

Summary:

1. add PocoNetSSL as a lib_depends
2. use Poco::Net::Context with HTTPSClientSession
