api - 如何使用 AutoRest 客户端传递客户端证书

Question

我们正在使用 AutoRest 基于 API Swagger 文件生成客户端代码。

我正在尝试将客户端证书传递给 API。但注意到生成的客户端代码不接受 WebRequestHandler。

生成的代码如下所示:

public MyTestApiV1(Uri baseUri, params DelegatingHandler[] handlers) : this(handlers)
        {
            if (baseUri == null)
            {
                throw new ArgumentNullException("baseUri");
            }
            this.BaseUri = baseUri;
        }

我觉得我错过了一些东西。有人设法使用 AutoRest 发送客户端证书吗？

尝试过这个，但 webRequestHandler 始终为空:

var webRequestHandler = client.HttpMessageHandlers.First() as WebRequestHandler;
            if (webRequestHandler != null)
            {
                var secretRetrieved = keyVault.GetSecretAsync("my-cert");
                var pfxBytes = Convert.FromBase64String(secretRetrieved.Result);
                // or recreate the certificate directly
                var certificate = new X509Certificate2(pfxBytes);
                webRequestHandler.ClientCertificates.Add(certificate);
            }

Answer 1

您可以使用另一个重载构造函数:

/// <summary>
/// Initializes ServiceClient using base HttpClientHandler and list of handlers.
/// </summary>
/// <param name="rootHandler">Base HttpClientHandler.</param>
/// <param name="handlers">List of handlers from top to bottom (outer handler is the first in the list)</param>
protected ServiceClient(HttpClientHandler rootHandler, params DelegatingHandler[] handlers)

ServiceClient 是生成的客户端的基类。因此，代码可能如下所示:

var secretRetrieved = keyVault.GetSecretAsync("my-cert");
var pfxBytes = Convert.FromBase64String(secretRetrieved.Result);
// or recreate the certificate directly
var certificate = new X509Certificate2(pfxBytes);
WebRequestHandler webRequestHandler = new WebRequestHandler();
webRequestHandler.ClientCertificates.Add(certificate);
var client = new MyTestApiV1(webRequestHandler);
client.BaseUri = baseUri;
