使用 ASP.NET 核心在 POST 请求的 Header 中包含身份验证

Question

我正在尝试请求接收 session ID 以与支付网关集成。

var m = System.Text.Encoding.Unicode.GetBytes("merchant." + merchant_Id + ":" + merchant_pass);
var b64Val = Convert.ToBase64String(m);
var SerSession = JsonConvert.SerializeObject(sessionRequest);
var client = new HttpClient();
string _ContentType = "application/json";
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(_ContentType));
client.DefaultRequestHeaders.Add("Authorization", String.Format("Basic {0}", b64Val));

var _UserAgent = "d-fens HttpClient";
client.DefaultRequestHeaders.Add("User-Agent", _UserAgent);
HttpContent _Body = new StringContent(SerSession);
]_Body.Headers.ContentType = new MediaTypeHeaderValue(_ContentType);
HttpResponseMessage response;
response = await  client.PostAsync(api_URL, _Body);
var content = response.Content.ReadAsStringAsync().Result;
return Ok(content); 

我收到（无效凭据）并且我确定我使用的凭据是正确的。我已经在 Python 和 PHP.

中测试了它们

试试这个

var authenticationString = $"{merchant_Id}:{merchant_pass}";
var base64EncodedAuthenticationString = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(authenticationString));
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", base64EncodedAuthenticationString);
