将 blazor-server 应用程序发布到服务器后无法从 tes.net.binance.vision 获得结果 [在本地主机工作]

Question

这是发布到服务器后的错误 [UBUNTU]

fail: Microsoft.AspNetCore.Components.Server.Circuits.CircuitHost[111]
      Unhandled exception in circuit 'YT-5hUsabWHhqsnewYD0_YAdubDWkaPxkx144q2ZYN0'.
      Binance.Common.BinanceClientException: Exception of type 'Binance.Common.BinanceClientException' was thrown.
         at Binance.Common.BinanceService.SendAsync[T](String requestUri, HttpMethod httpMethod, Object content)
         at Binance.Common.BinanceService.SendPublicAsync[T](String requestUri, HttpMethod httpMethod, Dictionary`2 query, Object content)
         at Binance.Spot.Market.CurrentAveragePrice(String symbol)
         at TORCHAIN.Components.CryptoTracker.PricesComponent.OnInitializedAsync() in A:\Users\sam_sepi0l\Desktop\PROJECTS\NEWFORUM\TORCHAIN\Components\CryptoTracker\PricesComponent.razor.cs:line 25
         at Microsoft.AspNetCore.Components.ComponentBase.RunInitAndSetParametersAsync()
         at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle, ComponentState owningComponentState)

这是 25 行：

   var result = await market.CurrentAveragePrice(symbol);

在本地主机上，它运行完美，我得到了结果，但在发布后它说这个错误。

这是方法调用：

private static HttpClient _httpClient = new HttpClient();
public List<string> Lista = new List<string>();
protected async override Task OnInitializedAsync()
{
    #region BinanceAPI
    using (_httpClient = new HttpClient())
    {
        _httpClient.BaseAddress = new Uri("https://testnet.binance.vision");
        _httpClient.Timeout = new TimeSpan(0, 0, 5);
        _httpClient.DefaultRequestHeaders.Clear();
        _httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
        _httpClient.DefaultRequestHeaders.Add("X-MBX-APIKEY", "APIKEY");
        _httpClient.DefaultRequestHeaders.Add("SecretKey", "SECRETKEY");
        var symbol = "BTCBUSD";
        var market = new Market(_httpClient);
        var result = await market.CurrentAveragePrice(symbol);
        BinancePrice? Token = JsonConvert.DeserializeObject<BinancePrice>(result);
        Lista.Add(Token!.Price.ToString());
    }
    #endregion
}

＃＃更新

我认为这是 linux 的问题。也许是一些代理或我应该打开或关闭的东西？

Answer 1

服务器位置和 binance 的制裁存在问题。 我将位置从美国更改为欧洲并且它有效。
