我正在尝试将数据传递到Web API并通过json检索结果。我一直得到f.f.错误：远程服务器返回错误：（401）未经授权。 这是代码。 我尝试过的事情：

string authInfo = XXXXXXX + ： + XXXXXXX; authInfo = Convert.ToBase64String（Encoding.Default.GetBytes（authInfo））; HttpWebRequest request =（HttpWebRequest）WebRequest.Create（ @ https：// elig。 nhia.gov.gh:5007/api/hp/authenticate/app）; request.Method = POST; request.Accept = application / json; charset = utf-8; request.Headers [ 授权] = 基本 + authInfo; 使用（ var streamWriter = new StreamWriter（request.GetRequestStream（））） { string json = new JavaScriptSerializer（）。Serialize（ new { GhanaCardNo = ， UMN = membershipNoTextBox.Text }）; streamWriter.Write（json）; streamWriter.Flush（）; streamWriter.Close（）; } var response =（HttpWebResponse）request.GetResponse（）; string strResponse = ; 使用（ var sr = new StreamReader（response.GetResponseStream（））） { strResponse = sr.ReadToEnd（）; }

解决方案

1）请永远不要发布您的登录凭据。 2）当使用Postman测试API，您将在响应正文中看到错误消息：

必须通过x-nhia-apikey请求头参数提供有效的API密钥。

因此，您还必须提供此处无人知晓的有效API密钥。 您应该联系网站所有者以获取所需信息。

I'm trying to pass data to a web API and retrieve results via json. I keep getting the f.f. error: The remote server returned an error: (401) Unauthorized. Here is the code. What I have tried:

string authInfo = "XXXXXXX" + ":" + "XXXXXXX"; authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo)); HttpWebRequest request =(HttpWebRequest)WebRequest.Create(@"elig.nhia.gov.gh:5007/api/hp/authenticate/app"); request.Method = "POST"; request.Accept = "application/json; charset=utf-8"; request.Headers["Authorization"] = "Basic " + authInfo; using (var streamWriter = new StreamWriter(request.GetRequestStream())) { string json = new JavaScriptSerializer().Serialize(new { GhanaCardNo = "", UMN = membershipNoTextBox.Text }); streamWriter.Write(json); streamWriter.Flush(); streamWriter.Close(); } var response = (HttpWebResponse)request.GetResponse(); string strResponse = ""; using (var sr = new StreamReader(response.GetResponseStream())) { strResponse = sr.ReadToEnd(); }

解决方案

1) Please never ever publish your logon credentials. 2) When testing the API with Postman you will see an error message in the response body:

A valid API Key must be provided via x-nhia-apikey request header parameter.

You therefore also must supply a valid API key which nobody here knows. You should contact the web site owner in order to get the needed information.
