Here is an article on how to use WebSocketSharp with BinanceAPI to keep the connection alive until you have your orders in place:
Keeping Your Connection to Binance API Alive – A Guide on How to Use WebSocketSharp
Introduction
————-
When working with Binance APIs, it is essential to establish a persistent connection to ensure a smooth exchange of data. However, disconnections can occur due to various reasons such as server maintenance or network issues. To avoid this, we will explore how to use WebSocketSharp to keep the connection to Binance API alive until you have your orders in place.
Prerequisites
- You have established a connection to BinanceAPI using the
BinanceClient
class.
- You are familiar with 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 establish 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 async Task StartConnectionAsync()
{
wait _ws.ConnectAsync().Wait();
}
public async Task DisconnectAsync()
{
wait _ws.DisconnectAsync().Wait();
}
}
class Program
{
static void Main(string[] args)
{
var client = new BinanceClient();
// Establish 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);
}
// Disconnect the WebSocket connection to close the persistent connection
await client.DisconnectAsync();
}
}
Using WebSocketSharp
Now that we have a persistent connection established, let’s modify our BinanceAPI call using WebSocketSharp:
usingSystem;
using System.Net.Http;
using System.Threading.Tasks;
public class OrderService
{
private readonly HttpClient _httpClient = new HttpClient();
public async Task GetOrderAsync(int id)
{
var orderRequest = new OrderRequest { Id = id };
var response = await _httpClient.PostAsJsonAsync(" orderRequest);
if (response.IsQueueStatusSuccess)
{
return await response.Content.ReadFromJsonAsync();
}
else
{
Console.WriteLine($"Error: {response.StatusCode}");
return null;
}
}
}
In this example, we use WebSocketSharp to establish 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.
Keep the connection alive
To keep the connection alive until you have your orders in place, we need to:
- Establish 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 incorporates these steps:
«`Csharp
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.
