Re: [Cppcms-users] Page handlers from configuration

[Saikumar G. <sai...@gm...>]

Great. The argument "url" solves my issue. 

    void loginpage(std::string url)
    dispatcher().assign("/login", &server::loginpage, this,0);
  
With this I can lookup the associated page handler through command pattern 
and it can be set in the configuration file.

Thanks.

Re: [Cppcms-users] Cookies

[Saikumar G. <sai...@gm...>]

Good catch. You were right, I had generated the output before 
setting the cookie. 
Moving it before the response().out() solved this issue.

Thank you.

[Cppcms-users] Windows Service and cppcms

[Jean-Marc C. <jm1...@gm...>]

Hello,

At work, we need to build somes WebServices on Windows 2008 R2. We don't 
want to use script language to do theses WS. My questions :

- Is it possible to use cppcms under Windows 2008 R2 Server ?
- Is it possible to compile cppcms with MinGW ?
- Is it possible to start cppcms http server as Windows Service ?

Thanks,

Jean-Marc

Also you have to know, that the cookies are not visible immediately, but
on the next request from the client.

Re: [Cppcms-users] Page handlers from configuration

[Artyom B. <art...@ya...>]

What do you mean?

- You mean what parameter was given?
  

  The obvious

  void loginpage(std::string url)

  dispatcher().assing("/login,&server::loginpage,this,0);
  

- What regular expression was used?
  For "reverse" path generation you can use
  URL mapping (the opposite of dispatching).


- What is the full mapping path? You can use CGI variables:
  request().path_info() to get the full path.

Re: [Cppcms-users] Cookies

[Artyom B. <art...@ya...>]

It is most likely because you had already generated some output before setting the cookie.

if you called response().out() -  than the headers were generated and written to the output.

So make sure you have no output requested.

[Cppcms-users] Cookies

[Saikumar G. <sai...@gm...>]

The cookies set in the cppcms app is not visible in the response header at 
the client side.

    response().set_cookie(cppcms::http::cookie("COOKIE1","value"));

The configuration is through fastcgi from lighttpd.

fastcgi.server = (
  "/main" => ((
    "bin-path" => "/home/dev/myapp/myapp -c /home/dev/myapp/config.js",
    "socket" => "/tmp/hello-fcgi-socket",
    "max-procs" => 1,
    "check-local" => "disable"
  ))
)

Could it be because the lighttpd is not forwarding the cookies sent from the 
cppcms app ?

Am I doing something wrong with the settings ?

Re: [Cppcms-users] URL dispatching help

[Troy W. <dr...@gm...>]

Thank you. I was so frustrated with not being able to figure it out, the
obvious things to do were no longer obvious to me! It was a simple typo on
my part and it seems to work now, but the solution raises a further
question.
What is mapper().assign( "...", "..." ) used for? All my URL dispatching
seems to work by only calling dispatcher().assign(...) to set up the URLs
with a callback function. What concept am I not understanding that would
require the mapper()?

Re: [Cppcms-users] Page handlers from configuration

[Saikumar G. <sai...@gm...>]

If there is a mapping like this

       dispatcher().assign("/login", &Server::loginpage, this);

Is possible to know the assigned path ( "login") at runtime from inside 
the loginpage() method ?

Thanks for the help. I used the code from your reply, but it causes dozens

Re: [Cppcms-users] URL dispatching help

[Artyom B. <art...@ya...>]

If you need two parameters i.e. go(std::string id,std::string urd) that you need provide sleections for both, i.e. 
dispatcher().assign( "/go/(\\d+)(.*)", &application::go, this, 1, 2 );

Where 1 - is first selected subexpression and 2 is the second one.

Also I'm not sure but it seems that you need go(std::string id,std::string url) without const.

[Cppcms-users] URL dispatching help

[Troy W. <dr...@gm...>]

Despite reading the docs and looking at the examples, I can't figure out
complex dispatching/mapping with regexes. I need some help please!

My callback member function looks like this: void go( const std::string id,
const std::string url ) { ... }
And the URL to map to the function looks like this: /go/{integer
id}/{string url}

For example:
/go/10/http://google.com - id=10, url=http://google.com
/go/2921/http://sourceforge.net - id=2921, url=http://sourceforge.net

The best I could come up with was this:

    dispatcher().assign( "/go/(\\d+)(.*)", &application::go, this, 2 );
    mapper().assign( "go", "/go/{1}/{2}" );

...but obviously that doesn't compile. What should the dispatcher and
mapper call look like to get the functionality I'm looking for?

Thank you for such an excellent framework!

Re: [Cppcms-users] pass security credentials using fcgi

[Artyom B. <art...@ya...>]

Sometimes it is very useful to have generic HTTP authentication that can be used across different platforms.

For example if you want to have centralized login connected to Domain controller etc. Apache has wide range
of modules for such authentication - Kerberos that for example allow to run any application behind common
scheme like svn apache module can use any authentication schemes provided by Apache.

In such case you may relay on the authentication that web server provides and use it as is.

When you relay on the web server you indeed need to use specific CGI variables that should

be defined by the web server, see: http://tools.ietf.org/html/draft-robinson-www-interface-00#page-10
as you had already mentioned them.

However it is not common practice for public web sites to use HTTP authentication.

Also once you use HTTP authentication you will still need to handle the authorization in your
application to handle the permissions.

[Cppcms-users] pass security credentials using fcgi

[Markus R. <us...@ma...>]

Hello Group!

I have a rather general question about fcgi but I still post in this group 
because I am interested in a solution which plays nicely with cppcms.

One way to authenticate users is to have some authentication code within 
cppcms and keep the auth state within a session. The drawback of this is:
- you need to write the authentication yourself
- you need to have a (in the worst case redudant) passwd/shadow

Another way is to use authentication methods found within webservers.
I am interested in how those security credentials are passed using fcgi.
E.g. in nginx I found "fastcgi_pass_header Authorization;" and to pass the 
information if we are in a secure session "fastcgi_param HTTPS $https;".
I wonder if other webservers also have this feature?

Is there a standard for which environment variables should be declared and 
how they should behave? Are the implementations found in apache/lighttpd 
fcgi standard compliant?

It seems like AUTH_TYPE and REMOTE_USER should be set for this feature.
Cppcms seems to have convenience functions for those.
Unfortunately I could not find detailed information about these.

Is this approach used in practice?

I also could not find anything about authentification in
http://cppcms.com/wikipp/en/page/secure_programming


best regards
Markus

Re: [Cppcms-users] session.server.settings example

[Artyom B. <art...@ya...>]

First of all take a look on some ready modules in contrib section

contrib/server_side/sessions


The factory function is called from CppCMS as

   f(srv.settings().find("session.server.settings")



So in your case the code

         base_ = val.get<std::string>("dir", "/tmp/");
          BOOSTER_INFO("session_memory_ext") << "base folder '" << base_;


Is not correct as the "val" is a string object i.e. is is STRING "dir:'/session_storage/'"

I would suggets:

1. Try to print to "val" to the stream so you know what you get in the factory.
2. Print the backtrace of the exception you catch so you can see where it comes from

Re: [Cppcms-users] Page handlers from configuration

[Artyom B. <art...@ya...>]

In general there is no built in loadable module support of the applications, it is planned for next
release: http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#Provide.Plugin.Framework

But many users had already implement such kind of support, there is class that allows to load modules easily

http://cppcms.com/cppcms_ref/latest/classbooster_1_1shared__object.html


And cppcms templates are fully pluggable, i.e. they are self registered so only thing you need to do is to link
the templates to shared object that you are loading.

[Cppcms-users] Page handlers from configuration

[Saikumar G. <sai...@gm...>]

Before I reinvent the wheel, I wanted to check with you first to see if there 
is an easier method to accomplish this.

Goal: I want to specify the dispatch handler method through means of a class 
whose instance is created through a class factory using a service name.
Why: So that we can specify the page handlers through the configuration file and
 not touch the main module for adding/updating/deleting a page. 

You can notice that the service module is created using a class factory and used 
for the assign method in dispatcher.
I know the below code is wrong and will not work, but wanted to show you the 
concept what I would like to accomplish.
Any ideas ?

void CPPCMSServer::initmapping( cppcms::service &srv ) {
	  string page = "/login"; // Read from the configuration
	  // Creates an instance of LoginServiceModule
	  ServiceModule *sm = CreateServiceModuleFactory(page);  
          dispatcher().assign(page, &ServiceModule::processRequest, sm);
}

class ServiceModule
{
public:
    virtual void processRequest(cppcms::application &app) = 0;
};

class LoginServiceModule : public ServiceModule {
public:
    LoginServiceModule() {}
    void processRequest(cppcms::application &app);
};

void LoginServiceModule::processRequest(cppcms::application &app) {
    // Process page request for "/main/login" page.
}

                        "shared_object":"/opt/libcppcms_session_memory_ext.so",
                        "settings":"dir:'/session_storage/'"
                }
        },

        session_memory_ext_storage(cppcms::json::value const &val)
        {

Re: [Cppcms-users] Dispatcher and URL Mapping

[Saikumar G. <sai...@gm...>]

Artyom, Thanks for your moderation.
Point noted. Will check the docs/list before reaching out.
Excellent Framework. Great work ! Thanks.

Re: [Cppcms-users] Dispatcher and URL Mapping

[Artyom B. <art...@ya...>]

Please guys stop...

Both you are right and wrong...

@Saikumar Gndapodi: please try to search for the answer next time in docs or in the list (this is a common issue) 
@Shiv Shankar Dayal: I would really expect that after that long time, other users would be able to answer or point to the answer for such a common question. It is not ok that I'm the only person helping others around. 

And finally try to be respectful to other list members even if you disagree.

Its quite apparent that you didn't understand a word I said earlier and 
it seems that you are in good mood to have an argument without taking 
anything into your mind.
Anyway. Thanks a lot and don't bother replying by wasting your time unless 
you have something to contribute to help others.
