Hello,

Is it possible to use the websocketpp in threaded non-blocking server ? For example - each connection (and/or on_message event inside the connection event) process with new thread, so the stall/processing of the connections/events can't influence on others. As I understand - for now the default processing model is single threaded - the next connection or event inside connection will not be handled until the previous exits. This is very confusing for many applications.

Thanks

Hi,

Thanks for the library...it looks super useful.

That said, one of the reasons I'm interested in WebSockets as a transport mechanism is the possibility of using it over an http proxy. I've tested this in-browser and it works via the proxy in question, but I can't figure out how I'd do it with websocketpp. I've looked around at boost::asio documentation and don't really see anything in there, either, except for one person that did it with a lot of very specific manual code, which I'm not sure it'd be easy to shoehorn into websocketpp (http://lists.boost.org/boost-users/2008/05/36356.php).

Any advice?

Thanks, Jeff

I use the examples named "echo_client" and "echo_server".The Server and Client can run normally on the Win7 and win8.It prompts "invalid state" when the programs run on the winXP.The Client can't connect with the Server.

And no, I have not blocked the port :) Even if I disable the firewall I cannot connect until I reboot the computer. Restarting the app does not help. Although other apps using boost asio directly or zmq works just fine.

I made a post on stack overflow but since I believe the issue must be related to websocketpp and boost asio somehow I post here too

I am using the echo server in the example directory for my tests.

Check that my app is listen on port 9002:

sudo netstat -lnp | grep 900
tcp6       0      0 :::9002                 :::*                    LISTEN      12695/./bin/echo_se 

Output from the echo server with debug

[2017-03-09 11:38:06] [devel] asio::async_accept

Output from telnet (since I only care about the tcp handshake at this point

telnet localhost 9002
Trying ::1...
(eventually timeout)

And If I close the echo server so no app is listening any more. Then I get (as expected)

telnet localhost 9002
Trying ::1...
Connection failed: Connection refused
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

So, now the OS notice that no one is listening and sends connection refused. I mean. This tells me that the traffic is not blocked and that the application has successfully made bind and listen. So why doesn't it work?

For completeness. After disabling ufw and rebooting the echo server prints this

and telnet this:

telnet localhost 9002
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

So then everything works perfekt!

And "after sudo ufw enable && sudo ufw disable" it does not work any more...

Also see: http://stackoverflow.com/questions/42693473/issue-with-accepting-connection-using-websocketpp-with-firewall-enabled

I also tried to compile the lib with standalone ASIO but it is the same...

Any help appreciated. Is it a way to make websocketpp sever even more minimal to try and find something that works?

Hi, I had an websocketpp server running for about a year now (only occasionally on a local linux machine for integration test of another system, so only one concurrent connection), but suddenly it stopped working: Clients cannot connect anymore (they timeout).

in dmesg i get the following error: request_sock_TCP: Possible SYN flooding on port 9002. Dropping request. Check SNMP counters. But there's only one connection, so it definetely cannot be "real" SYN flooding.

I tried it also with the echo_server and echo_client example => same problem.

I tried fiddling around with the "syn" options in /etc/sysctl.conf (enabling, disabling, changing memory), => no effect.

I also used debug_asio_no_tls => does not give any output on connection attempts.

However, it can't be my system all alone, when trying to set up a node js based websocket server, it works flawlessly.

Any ideas what might be the problem (as it is not a productive environment, workarounds are also highly appreciated)?

Hello,

just have a problem, i'm trying your websocketpp implementation. If i will create a "websocketpp::server request_server" and want to start listening by calling "request_server.listen(...)", there's a exception thrown from "server::start_listen" -> "m_acceptor.open(e.protocol()". The exception said that the handle is not valid! What can it be?

Thanks in Advance, Christian

Hello,

I just started using websocketpp about 2 months ago and now that's it's been integrated into my code for a while now, I'm now experiencing an occasional deadlock between two threads. I don't really understand what's causing it, but it looks like it's deadlocked in the bowels of websocketpp and boost. Does anyone have advice? The callstacks for the 2 threads are below. The line numbers may not be 100% accurate.

Thanks for your time and attention.

I'm compiling with gcc 7.3.0 on Ubuntu 18.04

I'm using the latest master branch of websocketpp and standalone asio from here https://github.com/chriskohlhoff/asio/tree/84e9a48ae6ff040311dfdd9bd4b8e761832509fd

I'm not sure if you can fix this or it's an issue with asio but I want to let you know about this.

Here's my code: example0.cpp

#define ASIO_STANDALONE
#include <websocketpp/config/asio_client.hpp>

int main() {
	return 0;
}

We have tried using this version and it works well as a websocket server.Is this branch an official release??? Since the descriptions quotes a list of features to be implemented would like to know when the official release would be??

Feature request to allow WebSocket++ to handle POST/PUT/ other non-GET methods with request bodies.

Example usage case: File Uploads (#164)

This is low priority because WebSocket++ is primarily a WebSocket server and not an HTTP server. However, the request is not particularly hard and WebSocket++ can already be hacked a bit to do it so a more clean/stable interface might be useful.

Sometimes when browser closes connection to my websocketpp server, I get:

[2016-09-09 19:40:53] [error] handle_read_frame error: websocketpp.transport:7 (End of File)

How I can fix it?

do i need use dh on tls server?

websocketpp::lib::asio::ssl::context::single_dh_use ctx->use_tmp_dh_file("dh.pem")

in the echo server example use this

Dear ALL: When I use demo broadcast server, if one of clients stop un-normal，how can i get the status of connection handler, that i can clear the handler:

It's basically impossible to add custom logging for this, as the logger instance is forcefully created internally within the library for each connection and you don't get to have any access to it, which makes it unnecessarily hard to have uniform logging.

It would be much preferable to have the option to specify the logger, by either passing it to the constructor of the client / server objects, or have callbacks that are called for logging purposes.

I'm trying to run this code from this example on Windows with vscode + cmake + vcpkg:

#include <websocketpp/config/asio_no_tls_client.hpp>
#include <websocketpp/client.hpp>
 
#include <iostream>
#include <string>
 
typedef websocketpp::client<websocketpp::config::asio_client> client;
 
int main() {
    bool done = false;
    std::string input;
 
    while (!done) {
        std::cout << "Enter Command: ";
        std::getline(std::cin, input);
 
        if (input == "quit") {
            done = true;
        } else if (input == "help") {
            std::cout
                << "\nCommand List:\n"
                << "help: Display this help text\n"
                << "quit: Exit the program\n"
                << std::endl;
        } else {
            std::cout << "Unrecognized Command" << std::endl;
        }
    }
 
    return 0;
}

With MSVC I have the following error:

[build] I:\code\test_websocketpp\build\vcpkg_installed\x86-windows\include\websocketpp/common/random.hpp(59,18): fatal error C1083: Cannot open include file: 'boost/random/uniform_int_distribution.hpp': No such file or directory [I:\code\test_websocketpp\build\ws-client.vcxproj]

Both seems to be lacking some boost files. So I've added entire boost to my vcpkg.json and wait for it to install and now my build folder is of 1GB size...

Thois solved problem with MSVC, but next mingw error was undefined reference to '__imp_WSAStartup', so I linked ws2_32 library.

Final version worked for me with both compilers:

cmake_minimum_required(VERSION 3.0.0)
project(wspp VERSION 0.1.0)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)

add_executable(ws-client ws-client.cpp)

find_package(websocketpp CONFIG REQUIRED)

target_link_libraries(ws-client PRIVATE 
    websocketpp::websocketpp
)

target_link_libraries(ws-client PRIVATE ws2_32)

{
    "name": "wspp",
    "version": "1.0.1",
    "dependencies": [
        "websocketpp",
        "boost"
	  ]
}

Is there a simpler way to compile the same example?

AFAIK websocket++ uses boost::thread and boost::regex to work correctly. Can this dependency be linked to std::threads and std::regex maybe? I'm trying to use websocket++ on a microcontroller and there's no API wrapper for boost::threads but there's one for std::thread.

Sorry I'm new to websocket++. I like what I'm seeing so far. But how can I load a certificate bundle (windows or linux) for the TLS connection? What API foo am I looking for? Also, is there more documentation on the API in general except for this tutorial?
