Ethereum: Binance Futures with LibwebSockets does not work
===================================================== ============= ====================
Introduction
————–
When building a C ++ application that requires a real-time price update from Binance Futures via WebSockets, it may be challenging to use the popular WebSockets Yair Gadel’s WebSockets project. However, in this article we will explore why Binance Futures with LibwebSockets does not work and provide alternative solutions.
Problem
———–
Binance Futures provides WebSocket API to get a real -time market data. Standard websocket API uses’ WSS: // Api.binance.com/WSThe end point, which can be accessed using JavaScript or other programming languages on the client's side. However, for safety limitations, this end point is not directly available from the C ++ application.
In order to overcome this limit, we will use a library called LibwebSockets, which provides a layer of abstraction to communicate WebSocket. In particular, we will use theLibwebSockets-Client ‘library to establish a connection with the WebSocket API Binance Futures.
Why Yair Gadelov’s WebSockets WRAPPER project?
——————————————-
The WebSockets Yair Gadel’s WebSockets project was built at the top of LIBWEBSOKETS and provides a suitable interface to work with WebSockets. However, it does not provide official integration of the binans of the future.
LibwebSockets vs yair gadelov’s webSockets wrap project
—————————————————— ————————————————— ——
Although both libraries provide similar functionality, there are some differences between them:
- LibwebSockets is a more general library that provides support for multiple protocols, including websocket.
- WebSockets Yair Gadelov WebSockets project is especially designed for Binance Futures and its own ownership protocol.
Binance Futures’ WebSocket API
———————————————-
Official webSocket API Binance Futures does not use standard API libwebSockets. Instead, it uses adapted implementation that is specific to their protocol.
In order to establish a connection with the WebSocket API -JAM BINANCE Futures using libwebsokets, we need to change the Webseckets Yair Gadel Websekets project to accommodate API -ja Binance Futures.
Alternative solution
———————-
After researching and experimenting with different libraries, I recommend using the LibssH2 'library' instead of libwebSockets. LibssH2 is a safe implementation of a SSH protocol that can be used to communicate on a website.
Here's an example of how you can useLibssH2to establish a binance with Binance Futures' WebSocket API:
` CPP
#include
#include
// initialize Libssh2 and create a new SSH Sesi
void init_sssh (const char *host, int port) {
SSH2_SESSION* SESS;
SSH2_Session_init (& sess);
// Connect to API Binance Futures’
ssh2_channel_open_connect (host, port, 0, & sess);
Iche
// Establish WebSocket connection to Binance Futures
void eating_Connection (ssh2_session sess, char channel_name) {
IF (SSH2_CHANNEL_OPEN_SESSION (SESS) == -1) {
Std :: cerr << "failed to open the channel:" << ssh2_channel_error (sess) << std :: endl;
return;
Iche
// Use a established connection for websocket communication
Iche
int main () {{)
Const Char *Host = « Bif.binance.
