无法让包装器 binance.net 工作

Question

我已经从https://github.com/JKorf/Binance.Net安装了包装器

使用他们的示例代码，我的应用中有以下内容：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using Binance.Net;
using Binance.Net.Enums;
using Binance.Net.Objects;
using Binance.Net.Objects.Spot;
using CryptoExchange.Net.Authentication;
using CryptoExchange.Net.Logging;

namespace binance_stream_user_data_updates
{
    class Program
    {
        static void Main(string[] args)
        {
            var client = new BinanceClient(new BinanceClientOptions{
                ApiCredentials = new ApiCredentials("key","secret"),
                BaseAddress = "https://testnet.binance.vision",
                LogVerbosity = LogVerbosity.Debug,
                LogWriters = new List<TextWriter> { Console.Out }
            });

            var startResult = client.Spot.UserStream.StartUserStream();

            if(!startResult.Success)
                throw new Exception($"Failed to start user stream: {startResult.Error}");

            var socketClient = new BinanceSocketClient();

            socketClient.Spot.SubscribeToUserDataUpdates(startResult.Data,
            null,
            data => {
                Console.WriteLine(data.Orders);
                },
            null,
            null);

            Console.ReadLine();

            socketClient.UnsubscribeAll();


        }
    }
}

然后我运行上面的应用程序，它似乎连接并开始等待，如下所示：

dotnet run
2021/02/26 20:36:51:863 | Binance    | Debug | Client configuration: LogVerbosity: Debug, Writers: 1, Credentials: Set, BaseAddress: https://testnet.binance.vision/, Proxy: -, RateLimiters: 0, RateLimitBehaviour: Wait, RequestTimeout: 00:00:30

2021/02/26 20:36:54:732 | Binance    | Debug | [3] Response received in 694ms: {"listenKey":"key"}

然后我发布订单

发布https://testnet.binance.vision/api/v3/order?symbol=BNBUSDT&side=SELL&type=MARKET&quantity=0.1&newClientOrderId=my_order_id_201&newOrderRespType=FULL&timestamp=1614370483356&signature=58cfd86cffc626703eac32f14bf0fa2e9af4850fb33974a03d1eee3f666df15f

当我这样做时，从上述代码运行的 websocket 什么也不输出。知道我做错了什么吗？

Answer 1

有些事情必须做才能得到正确的结果：

1. 您必须为BinanceSocketClient 指定选项
2. 您必须等待某个事件才能取消订阅
3. 在等待期间，您必须使用带有凭据的 Postman 应用程序（或其他类似应用程序）添加新订单（或新 OCO 订单）。 （这不在下面的代码中）

请看下面的代码：

async static Task Main(string[] args)
{
    var client = new BinanceClient(new BinanceClientOptions
    {
        ApiCredentials = new ApiCredentials("key", "secret"),
        BaseAddress = "https://testnet.binance.vision",
        LogVerbosity = LogVerbosity.Debug,
        LogWriters = new List<TextWriter> { Console.Out }
    });

    var startResult = client.Spot.UserStream.StartUserStream();

    if (!startResult.Success)
        throw new Exception($"Failed to start user stream: {startResult.Error}");

    var socketClient = new BinanceSocketClient(new BinanceSocketClientOptions
    {
        ApiCredentials = new ApiCredentials("key", "secret"),
        BaseAddress = "wss://testnet.binance.vision",
        LogVerbosity = LogVerbosity.Debug,
        LogWriters = new List<TextWriter> { Console.Out }
    });

    var stop = false;
    var subscribeResponse = socketClient.Spot.SubscribeToUserDataUpdates(
        startResult.Data,
        data =>
        {
            stop = true;
            Console.WriteLine($"Order updated: {data}");
        },
        data =>
        {
            stop = true;
            Console.WriteLine($"OCO Orders updated: {data.Orders}");
        },
        null,
        data =>
        {
            stop = true;
            Console.WriteLine($"Balance updated: ${data}");
        });
    
    if (subscribeResponse.Success)
    {
        while (!stop)
        {
            await Task.Delay(100);
        }
    }

    await socketClient.UnsubscribeAll();
}

Answer 2

您的socketClient 在订阅后立即取消订阅。

你需要换行

socketClient.UnsubscribeAll();
Console.ReadLine();

订阅事件直到控制台中的行被读取。

Answer 3

在您提供的代码中，您使用测试网 URL 创建一个带有选项的 BinanceClient，然后创建一个带有默认选项的 BinanceSocketClient，该选项将使用 wss://stream.binance.com:9443/ 作为基本 URL。

但是如果你使用测试网络，那么你必须使用对应的wss://testnet.binance.vision/ web socket URL；否则，你在真实网络中订阅了一个没有功能的listenKey，它不会通知你测试网络中发生的订单更新。

只需像这样创建BinanceSocketClient 实例：

socketClient = new BinanceSocketClient(new BinanceSocketClientOptions
{
    BaseAddress = "wss://testnet.binance.vision",
    LogWriters = new List<TextWriter> { Console.Out }
});
