What are some examples of using POCO libraries in C++?

Can you give me some examples of using POCO libraries in C++?

Sure! POCO libraries provide a set of C++ class libraries for network programming, file handling, and more. For example, you can use the Net library to create a simple HTTP server.

How do I set up a basic HTTP server using POCO?

To set up a basic HTTP server, you can use the following code snippet:

#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();
        server.stop();
        return 0;
    }
};

POCO_SERVER_MAIN(MyServerApp)

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

What other features do POCO libraries offer?

POCO libraries offer a wide range of features including:

• Networking (HTTP, FTP, SMTP)
• Data access (ODBC, SQLite)
• XML and JSON parsing
• Multithreading and synchronization
• File system access and manipulation These features make it a powerful toolkit for C++ developers.
