How do I put the exception message from gsoap then send to a std::string?

Question

I know the code below could print the exception, but how do I put the exception message to the std::string?

The code below prints the exception

    proxy.soap_stream_fault(std::cout);

soap_stream_fault takes any std::ostream&, according to its prototype. Just create a stringstream (or ostringstream). This would probably do it:

std::stringstream strstream;
proxy.soap_stream_fault(strstream);
std::string str{strstream.str()};
