Can you provide examples of using POCO in C++?

Can you provide examples of using POCO in C++?

Sure! POCO is a powerful C++ library for building networked applications. What specific examples are you looking for?

I'd like to see an example of a simple HTTP server.

Here's a basic example of a simple HTTP server using POCO:

#include <Poco/Net/HTTPServer.h>
#include <Poco/Net/HTTPServerRequest.h>
#include <Poco/Net/HTTPServerResponse.h>
#include <Poco/Net/HTTPRequestHandler.h>
#include <Poco/Net/HTTPRequestHandlerFactory.h>
#include <Poco/Util/ServerApplication.h>

class HelloWorldRequestHandler : public Poco::Net::HTTPRequestHandler {
public:
    void handleRequest(Poco::Net::HTTPServerRequest& request, Poco::Net::HTTPServerResponse& response) {
        response.setContentType("text/html");
        std::ostream& out = response.send();
        out << "<h1>Hello, World!</h1>";
    }
};

class HelloWorldRequestHandlerFactory : public Poco::Net::HTTPRequestHandlerFactory {
public:
    Poco::Net::HTTPRequestHandler* createRequestHandler(const Poco::Net::HTTPServerRequest& request) {
        return new HelloWorldRequestHandler();
    }
};

class MyServerApp : public Poco::Util::ServerApplication {
protected:
    int main(const std::vector<std::string>& args) {
        Poco::Net::HTTPServer server(new HelloWorldRequestHandlerFactory(), Poco::Net::ServerSocket(8080), new Poco::Net::HTTPServerParams);
        server.start();
        waitForTerminationRequest(); // wait for CTRL-C or kill
        server.stop();
        return 0;
    }
};

POCO_SERVER_MAIN(MyServerApp)

This code sets up a simple HTTP server that responds with "Hello, World!".

That looks great! Can you explain how to compile this code?

To compile this code, you need to have the POCO libraries installed. You can use the following command:

g++ -o myserver myserver.cpp -lPocoNet -lPocoFoundation

Make sure to replace myserver.cpp with the name of your source file. This command links the necessary POCO libraries.
