远程服务器返回错误：（401）未经授权。 [英] The remote server returned an error: (401) unauthorized.

问题描述

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(@"https://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.
