Ethereum: WebSocketSharp with BinanceAPI

Here is an article on how to use WebSocketSharp with BinanceAPI to keep the connection alive until your order arrives:

Keeping Your Binance API Connection Alive: A Guide to Using WebSocketSharp

Introduction

————-

When working with Binance APIs, it is essential to establish a persistent connection for smooth data exchange. However, connection interruptions can occur for various reasons, such as server maintenance or network issues. To avoid this, we will look at how you can use WebSocketSharp to keep your connection to the Binance API alive until your orders are placed.

Prerequisites

• You have established a connection to the BinanceAPI using the BinanceClient class.

• Know the basics of the WebSocket protocol and the BinanceAPI WebSocket endpoint (ws.binance.com).

Connection Setup

Before we dive into the solution, let’s create a simple example to demonstrate how to create a persistent connection:

using System;
using System.Net.Http;
using System.Threading.Tasks;
public class BinanceClient
{
private, readonly HttpClient _httpClient = new HttpClient();
private, readonly WebSocket _ws = new WebSocket ("ws.binance.com:9001");
public asynchronous Task StartConnectionAsync()
{
await _ws.ConnectAsync().Wait();
}
public asynchronous Task DisconnectAsync()
{
await _ws.DisconnectAsync().Wait();
}
}
Class Program
{
static void Main(string[] args)
{
var client = new BinanceClient();
// Create a persistent connection by calling StartConnectionAsync
await client.StartConnectionAsync();
// Simulate some API calls to test the connection
for (int i = 0; i < 10; i++)
{
var result = await client.GetOrderAsync(i);
Console.WriteLine(result);
// Wait 1 second before checking again
await Task.Delay(1000);
}
// To close the persistent connection, close the WebSocket connection
await client.DisconnectAsync();
}
}

Using WebSocketSharp

Now that we have a persistent connection, let’s modify the BinanceAPI call using WebSocketSharp:

using system;
using System.Net.Http;
using System.Threading.Tasks;
Public class OrderService
{
private, read-only HttpClient _httpClient = new HttpClient();
public async Task GetOrderAsync(int id)
{
var orderRequest = new OrderRequest { Id = id };
var response = await _httpClient.PostAsJsonAsync(" orderRequest);
if (response.IsSuccessStatusCode)
{
return await response.Content.ReadFromJsonAsync();
}
else
{
Console.WriteLine($"Error: {response.StatusCode}");
return null;
}
}
}

In this example, we use WebSocketSharp to create a persistent connection and simulate API calls to retrieve orders. The “GetOrderAsync” method sends a POST request to the BinanceAPI endpoint with the order details in JSON format.

Keeping the connection alive

To keep the connection alive until your order arrives, we need the following:

• Create a persistent connection using StartConnectionAsync.

• Simulate API calls to test the connection.

• Wait 1 second before checking again and reconnecting if necessary.

Here is an updated code snippet that includes the following steps:

using System;

using System.Net.Http;

using System.Threading.Tasks;

Public class OrderService

{

private, readonly HttpClient _httpClient = new HttpClient();

private static readonly WebSocket _ws = new WebSocket (“ws.binance.
