C# 通过代理使用KeyVault客户端
目前,我在启动期间使用Azure KeyVault加载一些配置,如下所示:C# 通过代理使用KeyVault客户端,c#,azure,asp.net-core,azure-keyvault,C#,Azure,Asp.net Core,Azure Keyvault,目前,我在启动期间使用Azure KeyVault加载一些配置,如下所示: configBuilder .AddAzureKeyVault(keyVaultConfigSection.Vault, GetKeyVaultClient(clientConfigSection, keyVaultConfigSection), new DefaultKeyVaultSecretManager()) .AddEnvironmentVariables(); private static
configBuilder
.AddAzureKeyVault(keyVaultConfigSection.Vault, GetKeyVaultClient(clientConfigSection, keyVaultConfigSection), new DefaultKeyVaultSecretManager())
.AddEnvironmentVariables();
private static KeyVaultClient GetKeyVaultClient(ClientConfigSection clientConfigSection, KeyVaultConfigSection keyVaultConfigSection)
{
HttpClient httpClient = null;
//proxy
if (!CustomEnvironment.NotProductionEnvironment())
{
var handler = new HttpClientHandler()
{
Proxy = new WebProxy(keyVaultConfigSection.Proxy),
UseProxy = true
};
httpClient = new HttpClient(handler);
}
return new KeyVaultClient(async (authority, resource, scope) =>
{
var authContext = new AuthenticationContext(authority);
var clientCred = new ClientCredential(clientConfigSection.ClientId, clientConfigSection.ClientSecret);
var result = await authContext.AcquireTokenAsync(resource, clientCred);
if (result == null)
throw new InvalidOperationException("Failed to retrieve access token for Key Vault");
return result.AccessToken;
}, httpClient ?? new HttpClient()
);
}
当我不在生产环境中时,这很好用。
但在我们的生产环境中,keyvault被阻止,因此我们必须通过代理
但在运行代码时,我收到以下错误:Microsoft.Azure.KeyVault.Models.KeyVaultErrorException:“操作返回了无效的状态代码“BadRequest”
以前有没有人这样做过,可以为我指出正确的方向?这似乎还没有解决,下面是答案 1.引用
System.Net.Http.WinHttpHandler
Nuget包以访问.Net核心中的WinHttpHandler
2.创建了一个新的MyKeyVaultCredential,该凭证继承自KeyVaultCredential并覆盖ProcessHttpRequestAsync
方法
public override async Task ProcessHttpRequestAsync(HttpRequestMessage request, CancellationToken cancellationToken)
{
if (request == null)
{
throw new ArgumentNullException("request");
}
var accessToken = await PreAuthenticate(request.RequestUri).ConfigureAwait(false);
if (!string.IsNullOrEmpty(accessToken))
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
else
{
var httpClientHandler = new WinHttpHandler()
{
WindowsProxyUsePolicy = WindowsProxyUsePolicy.UseCustomProxy,
Proxy = new MyWebProxy(configuration),
SendTimeout = TimeSpan.FromSeconds(120),
ReceiveDataTimeout = TimeSpan.FromSeconds(120),
ReceiveHeadersTimeout = TimeSpan.FromSeconds(120),
};
3.当我实例化KeyVault服务时,我必须向WinHttpHandler提供我的代理和新的key vault凭据实例
var httpClientHandler = new WinHttpHandler()
{
WindowsProxyUsePolicy = WindowsProxyUsePolicy.UseCustomProxy,
Proxy = new MyWebProxy(configuration),
SendTimeout = TimeSpan.FromSeconds(120),
ReceiveDataTimeout = TimeSpan.FromSeconds(120),
ReceiveHeadersTimeout= TimeSpan.FromSeconds(120),
};
var httpClient = new HttpClient(httpClientHandler);
client = new KeyVaultClient(new MyKeyVaultCredential(configuration, GetToken), httpClient)
希望这能有所帮助。它似乎还没有被修复,下面是答案 1.引用
