c# - 将工作邮递员请求转换为 C# (HttpClient)

问题描述

很难将成功的 Postman 请求转换为 C# 中的成功请求。使用 HttpClient 显示我的代码，但也尝试使用 PostSharp 和 HttpRequest。我正在使用具有密码的本地 pfx 证书文件。

在邮递员中：

• Added the PFX cert to Client Certificates
• Authorization tab has username and password (Basic Auth)
• Authorization header automatically generates based on above ("Basic <encoded username/password>")
• Body is "{}"

发送成功 (200)。

使用 HttpClient：

        var host = @"https://thehost/service/verb?param1=blah&param2=1111111";
        const string certName = @"C:\Key.pfx";
        const string userName = "userName";
        const string certPassword = "password1";
        const string authPassword = "password2";

        var handler = new HttpClientHandler();
        handler.ClientCertificateOptions = ClientCertificateOption.Manual;
        //tried many combinations here
        handler.SslProtocols = SslProtocols.Tls| SslProtocols.Tls11 | SslProtocols.Tls12 | SslProtocols.Tls13;
        var cert = new X509Certificate2(certName, certPassword);
        handler.ClientCertificates.Add(cert);
        //not sure if this is needed
        handler.ServerCertificateCustomValidationCallback += (message, certificate2, arg3, arg4) => true;
        
        var client = new HttpClient(handler);
        //not sure if these are needed
        client.DefaultRequestHeaders.Clear();
        client.DefaultRequestHeaders.ConnectionClose = true;
        //added this to both the request and the client.  Also tried "*/*" for both
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        
        var request = new HttpRequestMessage();
        request.RequestUri = new Uri(host);
        request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        request.Content = new StringContent("{}", Encoding.UTF8, "application/json");
        request.Method = HttpMethod.Post;

        //basic auth header
        var authenticationString = $"{userName}:{authPassword}";
        var base64EncodedAuthenticationString = Convert.ToBase64String(Encoding.UTF8.GetBytes(authenticationString));
        var authHeader = new AuthenticationHeaderValue("Basic", base64EncodedAuthenticationString);
        request.Headers.Authorization = authHeader;

        try
        {
            var httpResponseMessage = client.SendAsync(request).ConfigureAwait(false).GetAwaiter().GetResult();
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        }

这将返回未经授权 (401)。响应文本包含“无效的用户名或密码”。

关于两个请求之间可能不匹配的任何想法？
