[Cppcms-users] Problem with Server Side Events

[eric m. <mid...@gm...>]

Hello,

I have been wrestling with a cppcms-problem all day and find myself out of
options. Relevant sources are included.

I'm controlling a robot via a web-interface and always have a single user.
The robot reports status to the browser via SSE which is working fine. The
robot-thread reports status-strings via boost/signal2 to the
StatusStreamServer which sents events to a webpage where I can see them.

There is another stream I use when a new usb-device is discovered or lost
(via the udev library). That also results in a boost-signal but now to the
DeviceManagementStreamServer. This results in a modal popup in the browser.
If the popup is closed by the user, the page is reloaded via
location.reload(true) to accommodate for the new or removed usbdevice (menu
is changed with new or removed options). And that repeats the last
SSE-event for some reason, which results in the same popup again.

I want is to be able to clear SSE events that have been sent but can't
figure out how to do that. Who knows how to do this?

Furthermore I notice that connections are lost about every 30 seconds,
which seems to be some regulated timeout. Where is that configured? The
other thing I notice is that sometimes SSE events are sent without content
and without me initiating them. Where do these come from?

Any help is welcome.

Both StreamServers are created like this:

        // Device Management Stream
        booster::intrusive_ptr<StreamServer> deviceManagementStreamServer =
new DeviceManagementStreamServer(service, "DeviceManagementStreamServer");
        deviceManagementStreamServer->connectSlot();
        service.applications_pool().mount(deviceManagementStreamServer,
cppcms::mount_point("/device_management_stream"));

        // Status Stream
        booster::intrusive_ptr<StreamServer> statusStreamServer = new
StatusStreamServer(service, "StatusStreamServer");
        statusStreamServer->connectSlot();
        service.applications_pool().mount(statusStreamServer,
cppcms::mount_point("/status_stream"));

Kind regards,
Eric

Re: [Cppcms-users] How to fullfill ajax-call from different thread?

[eric m. <mid...@gm...>]

Hi Artyom,

Thanks for clarifying.

To answer your question: I have a thread that controls a motor and another
thread that services a webinterface. I send a command from the webthread to
the motorthread via an ajax-call and that has to be asynchronous otherwise
it will not respond to input from the user. Meanwhile the motorthread
starts doing its thing and that can take a while but it has to report back
status to the user. I now use two asynchronous ajax-calls: one for
receiving the status from the motorthread that waits for it and another one
to send the command to the motorthread that returns immediately. When I
asked the question my intention was to report back with using the second
ajax-call for receiving the status from the motorthread.

There's another thing I'm wondering about. Given the ticker_example: is it
possible to have two independent streams under the same endpoint, say
/ticker/stream1 and /ticker/stream2 and if yes how would I do that?

Kind regards,
Eric

Re: [Cppcms-users] CppCMS-Embedded web root

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

Wouldn't instead of

         { "regex" : "/()" , "pattern" : "/mb.fcgi/index" },
         dispatcher().assign("/index",&site::index,this);

The following would work out of the box

         dispatcher().assign("/",&site::index,this);

i.e. without this specific pattern.

To be honest I don't clearly understand what are you trying to do.

You have two types of applications:

1. Synchronous - running in threads and returning result immediately
2. Asynchronous - running in a single event loop - that can postpone
the response or keep long running open connections if needed.

You can "send" messages from synchronous apps (or what ever thread)
to asynchronous apps by posting callbacks to the main
event loop - i.e. service().post(some_function) such that this
"some_function" would be executed in the event loop and can interact
with the async apps.

So for example you can have a generic thread that posts every minute a
message to the chat from some thread
using this callback method.

Re: [Cppcms-users] CppCMS-Embedded web root

[Rodrigo E. <rod...@gm...>]

Hi Everyone,

First of all, I would like to thanks the fast feedback of Stanimir and good
explanation that Artyom Beilis did. I am glad to say that this *thread was
resolved*.
With base on the Artyom's explanation I understood how the routing of urls
works.
 I resolved my problem in this way:
First, I created index route that is the main page:

           dispatcher().assign("/index",&site::index,this);
            mapper().assign("index","/index");

And all the other url I created in the same form:

           dispatcher().assign("/contact-form",&site::contact_form,this);
            mapper().assign("contact_form","/contact-form");

            dispatcher().assign("/do-something,&site::something,this);
            mapper().assign("something","/do-something");


To accomplish my objective, I used two regex for the rewrite url rules,
like that:

        { "regex" : "/()" , "pattern" : "/mb.fcgi/index" },
        { "regex" : ".*" , "pattern" : "/mb.fcgi$0" }

The first one, does the route for url with "/" and empty urls (
http://domain.com/ and http://domain.com). And the second executes the rest
of the urls (http://domain.com/contact-form and
http://domain.com/do-something).

I hope this thread may help another person with the same doubt

Best Regard

[Cppcms-users] How to fullfill ajax-call from different thread?

[eric m. <mid...@gm...>]

Hi,

Taking the json_rpc_chat example as a starting point, is it possible to
respond to get() from another thread? Let me elaborate a bit on that.

In the chat example the get activates a callback that is called by a post
from the browser via the broadcast method. Is it possible to let this
callback be called by a different server-thread that is performing a task
and comes back with the result to be returned to the original get activated
by the browser?

To put it differently, is it possible to interact with the json_rpc_server
and fullfill callbacks from outside?

Reason for asking is that I'm using ajax-calls to perform tasks on the
server but I do not want the browser to hang up on it while waiting for the
result.

Kind regards,
Eric

Re: [Cppcms-users] CppCMS-Embedded web root

[Rodrigo E. <rod...@gm...>]

Hi Everyone,

I decided to give up CppCMS-Embedded and fight with the lighttpd. I
configured the lighttpd to execute the application in the "root" of the web
service with the following configuration:

server.port = 8080
server.bind = "127.0.0.1"

fastcgi.server = ( "/" => ( "localhost" => (
        "bin-path" =>
"/home/emygdio/Documents/Estudo/Progamacao/C++/CppCms/RootWebServer/hello
-c
/home/emygdio/Documents/Estudo/Progamacao/C++/CppCms/RootWebServer/etc/config-lighthttpd-2.js",
        "socket" => "/tmp/hello-fcgi-socket",
        "fix-root-scriptname" => "enable",
        "check-local" => "disable",
  )))

The pretty urls work very well, like http://domain.com/some-pretty-url. But
the empty router like this http://domain.com/, still doesn't work.

Any assist will be very welcome

Thanks

Re: [Cppcms-users] CppCMS-Embedded web root

[Rodrigo E. <rod...@gm...>]

I think that I need to explain better what I would like expect from the
CppCms. I have a little application that I wrote in Java and have specific
urls indexed by google:
    http://domain.com/ --> reflects the main page
    http://domain.com/[others-pretty-url] --> reflects each functions of
the application.
The application urls were indexed by google, and I don't want to lose these
urls. I need to rewrite this application in C++ and I decided to use
CppCms. Then I expect to use the same URLs as were indexed by Google. The
main page need to responds the root url (http://domain.com/) and the other
urls need respond like pretty urls (http://domain.com/some-pretty-url).

I did as Artyom tells me to do. Changing the rewrite rules as below:

change:

{ "regex" : ".*" , "pattern" : "/mb.fcgi$0" }

for this:

{ "regex" : "/(.*)" , "pattern" : "/mb.fcgi$1"}

Immediately resolved the problem with the root url, but the rest of urls
stop to work because the server takes the part after the "/" and
concatenates with the /mb.fcgi. Unhappily  there isn't any url with no "/"
before them.
I tried overcome that  changing the dispatcher configuration of the url,
like that:

I changed this:
   dispatcher().assign("/contact-form",&my_app::contact_form,this);
   mapper().assign("contact_form","/contact-form");

For this:
   dispatcher().assign("contact-form",&my_app::contact_form,this);
   mapper().assign("contact_form","contact-form");

Unhappily this changing didn't work.

Anybody has some idea how I can resolve that.
Thanks

[Rodrigo E. <rod...@gm...>]

Hi Artyom,

Thanks very much for your feedback. I tested the virtual main method and is
executing properly. I changed the regex and the root url works very well.
The problem now is that any other url just works if I add an extra "/" on
the begin on the path.

Thanks

1st check if cppcms::application::main is called (I think it should)
it is virtual
member function so you can override it.

2nd When you access to "localhost:8080" you get request GET / HTTP/1.0
it is mapped according to the rules to

   /mb.fcgi/

Than /mb.fcgi is matched and the path you get is "/"

When you map to "" you Require empty path and thus it does not get dispatched.

The correct is always to map to something starting with "/" or map to
"/?" i.e. last "/" is optional.


You can also use little bit different rule

Instead of this

{ "regex" : ".*" , "pattern" : "/mb.fcgi$0" }

Use

{ "regex" : "/(.*)" , "pattern" : "/mb.fcgi$1" }

Than none of your urls will start from "/"

it does not matter how do you do it - just pic and convention and stick to it.

HI Stanimir,

First, thank you very much for your feedback . Yes, I did read both of
these documentations.
Below have the main class of the example that I'm trying to execute:

#include <cppcms/application.h>#include
<cppcms/applications_pool.h>#include <cppcms/service.h>#include
<cppcms/http_response.h>#include <cppcms/url_dispatcher.h>#include
<cppcms/url_mapper.h>#include <iostream>#include "content.h"
   class my_app : public cppcms::application{
      public:
         my_app(cppcms::service& s) : cppcms::application(s){
               dispatcher().assign("",&my_app::well_come,this);
               mapper().assign("");
               mapper().root("");
         }
    void well_come(){
        content::index ci;
        ci.message = "Hello ";
        render("index",ci);
    }
  };
  int main(int argc,char ** argv){
    try{
        cppcms::service srv(argc,argv);
        srv.applications_pool().mount(
          cppcms::applications_factory<my_app>()
        );
        srv.run();
     }catch(std::exception const & e){
         std::cerr<<e.what()<<std::endl;
     }}



Thanks,
Rodrigo

Re: [Cppcms-users] CppCMS-Embedded web root

[Stanimir M. <sta...@zo...>]

Hello Rodrigo,

Did you try this documentation
http://cppcms.com/wikipp/en/page/run_application_web_server_root#CppCMS-Embedded
If it didn't help, then try to put this line in the constructor of
your my_app (the one that inherited from cppcms::application)

  mapper().root("");

See here http://cppcms.com/wikipp/en/page/cppcms_1x_tut_url_mapping#Mapping

[Cppcms-users] CppCMS-Embedded web root

[Rodrigo E. <rod...@gm...>]

Hi Everyone,

I am trying a simple example with CppCms and I would like to execute all my
applications relative to the web application root. I don't want execute the
application relative to the script path. Ex localhost:
8080/script-path/relative-path-to-my-application, and instead of this, I
would like the path for my application would be like: localhost:
8080/relative-path-to-my-application. I would like to execute this
application using the CppCMS-Embedded. I am trying a super simple example
and I had no success. All the time I try the root url (
http://localhost:8080/) I get a 404 error like that:


Connection              close

Content-Encoding  gzip

Content-Type           text/html; charset=utf-8

User-Agent            Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:44.0)
Gecko/20100101 Firefox/44.0

Below the config.js of my example:


config.js:

{
  "http" : {
      "script" : "/mb.fcgi",
      "rewrite" : [
          { "regex" : "/media(/.*)?", "pattern" : "$0" },
          { "regex" : ".*" , "pattern" : "/mb.fcgi$0" }
      ]
   },
   "service": {
      "api":"http",
      "port":8080
    },
   "views" : {
       "paths" : [ "./" ],
       "skins" : [ "my_app"],
    },}


What's I missing in my configurations? Why the CppCMS-Embedded is not
routing for the web application root .

Thanks.

Re: [Cppcms-users] json

[Василий Т. <par...@gm...>]

All the ways to deserialize this string (or alternative - with nested json
inside array) to cppcms::json::value give undefined result.

load() stops on '[' or something like that.

(ver.1.0.5)

Is there a way to deal with json arrays like

I can't force cppcms to load such string into json without error.
The only way is to use nested array as string value for a while :(

Not really...

It is one of 1000 tricks to work on Bots. If it becomes common than bot would
know how to find them. i.e. they wouldn't run entire JS engine but
rather search for document.write.

See it isn't really security feature as it isn't enhances security it
rather limits
users who does not run JavaScript to use the form. Which isn't always desirable.

It works it particular case but it does not help in general. Fighting spammers
is never ending battle that needs you to trick a spammer or detect one.

In my bot fight I needed to do many things, sometimes that are very
tight to a specific application domain. So there is no "general way to go"

Finally it is your effort vs his effort - your trick vs his. It is
very different
from general secure programming which is about stopping bad guy who
knows exactly what are you doing and can do whatever he wants to
hack your system.

I am not debating. As long as its design has nothing to do with attack
protection, I will leave it as is.

Re: [Cppcms-users] Why wikipp calls document.write() to generate simple <form> tag?

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

It is simple spam robot filter.

i.e. most spam bots search HTML for form tag and look the post address
to send some garbage.
Most of them do not run JavaScript so they wouldn't find the address
to post data unless they
write specific code for wikipp - which is likely isn't something bot
writers would bother.

Simple but yet efficient anti-robot security layer.
