c# - Kusto 客户端无法向服务 : Request headers must contain only ASCII characters 发送请求

Question

我正在使用以下代码生成连接字符串

var kustoUri = $"https://{clusername}.{region}.kusto.windows.net";
var dmKustoUri = $"https://ingest-{clusername}.{region}.kusto.windows.net";

this.engineKustoConnectionStringBuilder = new KustoConnectionStringBuilder(kustoUri)
    .WithAadApplicationKeyAuthentication(applicationClientId, applicationKey, authority);
this.dmKustoConnectionStringBuilder =
    new KustoConnectionStringBuilder(dmKustoUri)
        .WithAadApplicationKeyAuthentication(applicationClientId, applicationKey, authority);

但是当我运行如下命令时

using (var client = KustoClientFactory.CreateCslAdminProvider(this.engineKustoConnectionStringBuilder))
{
    var command = CslCommandGenerator.GenerateTableCreateCommand(table, columns);

    client.ExecuteControlCommand(command);
}

我不断收到错误消息“Kusto 客户端无法向服务发送请求:请求 header 必须仅包含 ASCII 字符。”

我已启用详细跟踪，但我发现它仍在尝试连接我的 Azure 用户而不是 AadApplicationKeyAuthentication

这是日志行:

使用的 Nuget 包:

<PackageReference Include="Microsoft.Azure.Kusto.Data.NETStandard" Version="6.1.8" />
<PackageReference Include="Microsoft.Azure.Kusto.Ingest.NETStandard" Version="6.1.8" />

更新:

如果我使用 FullFx 4.7.1 和他们的 NuGetPackages 就可以了!

  <package id="Microsoft.Azure.Kusto.Data" version="6.1.8" targetFramework="net471" />
  <package id="Microsoft.Azure.Kusto.Ingest" version="6.1.8" targetFramework="net471" />

感谢您报告此事，@JSC。快速浏览一下，我认为 .NET Framework 的 HttpClient 中的 HttpClient 行为与我们将要查看的行为之间存在差距。
