PageCompiler: Extracted page write from handleRequest

Open Fabio3rs opened this issue 2 years ago • 0 comments

Hi. I would like to use the Poco PageCompiler to create HTML emails, so I made these tweaks. I hope you will find it useful.

Thanks.

Example: Input page template

<%@ page class="TimeHandler" %>
<%!
    #include "Poco/DateTime.h"
    #include "Poco/DateTimeFormatter.h"
    #include "Poco/DateTimeFormat.h"


    using Poco::DateTime;
    using Poco::DateTimeFormatter;
    using Poco::DateTimeFormat;
%><%
    DateTime now;
    std::string dt(DateTimeFormatter::format(now, DateTimeFormat::SORTABLE_FORMAT));
%>
<html>
<head>
<title>Time Sample</title>
</head>
<body>
<h1>Time Sample</h1>
<p><%= dt %></p>
</body>
</html>

Output header TimeHandler.h:

#ifndef TimeHandler_INCLUDED
#define TimeHandler_INCLUDED


#include "Poco/Net/HTTPRequestHandler.h"
namespace Poco {
namespace Net {
class HTMLForm;
}
}


class TimeHandler: public Poco::Net::HTTPRequestHandler
{
public:
	void handleRequest(Poco::Net::HTTPServerRequest& request, Poco::Net::HTTPServerResponse& response) override;
	void stringify(std::ostream &responseStream, Poco::Net::HTMLForm &form);
};


#endif // TimeHandler_INCLUDED

Ouput source TimeHandler.cpp:

#include "TimeHandler.h"
#include "Poco/Net/HTTPServerRequest.h"
#include "Poco/Net/HTTPServerResponse.h"
#include "Poco/Net/HTMLForm.h"
#line 2 "/mnt/projects/Projects/poco/build/bin/aaa/page.cpsp"

    #include "Poco/DateTime.h"
    #include "Poco/DateTimeFormatter.h"
    #include "Poco/DateTimeFormat.h"


    using Poco::DateTime;
    using Poco::DateTimeFormatter;
    using Poco::DateTimeFormat;


using namespace std::string_literals;


void TimeHandler::handleRequest(Poco::Net::HTTPServerRequest& request, Poco::Net::HTTPServerResponse& response)
{
	response.setChunkedTransferEncoding(true);
	response.setContentType("text/html"s);

	Poco::Net::HTMLForm form(request, request.stream());
	std::ostream& responseStream = response.send();
	stringify(responseStream, form);
}

void TimeHandler::stringify(std::ostream &responseStream, [[maybe_unused]] Poco::Net::HTMLForm &form)
{
	responseStream << "\n";
#line 11 "/mnt/projects/Projects/poco/build/bin/aaa/page.cpsp"

    DateTime now;
    std::string dt(DateTimeFormatter::format(now, DateTimeFormat::SORTABLE_FORMAT));
	responseStream << "\n";
	responseStream << "<html>\n";
	responseStream << "<head>\n";
	responseStream << "<title>Time Sample</title>\n";
	responseStream << "</head>\n";
	responseStream << "<body>\n";
	responseStream << "<h1>Time Sample</h1>\n";
	responseStream << "<p>";
#line 21 "/mnt/projects/Projects/poco/build/bin/aaa/page.cpsp"
	responseStream << ( dt );
	responseStream << "</p>\n";
	responseStream << "</body>\n";
	responseStream << "</html>\n";
	responseStream << "\n";
}

Example use with MailMessage:


        Poco::Net::MailMessage message;

        std::stringstream sstr;

        TimeHandler msg;
        Poco::Net::HTMLForm form;
        msg.stringify(sstr,  form);
        
        message.setContentType("text/html; charset=UTF-8");
        message.setContent(sstr.str(), Poco::Net::MailMessage::ENCODING_8BIT);
