StatusCode：401，ReasonPhrase：使用C＃通过HTTPClient调用Post方法时显示'未授权'

Question

我试图通过HTTP客户端访问API的Post方法并传递AuthToken。当我尝试访问post man时，我能够得到响应，但是当我用C＃运行时，得到了StatusCode：401，ReasonPhrase：'未授权'错误。我与我的代码一起共享邮递员的请求和响应屏幕。任何人都可以让我知道我在代码中所犯的错误以及如何解决问题。下面

Postman Request Header and Response Body

Postman Request Body

是我的C＃代码。

public class PostEmpData 
{ 
    public string cExternalGUID = "10134", 
    cEmployeeID = "10134", cLastName = "Anderson", cFirstName = "Derek", cAccessGroup = "", cActive = "A"; 
    public int nCardNumber = 10134, nPayMethod = 2; 
    public string[] cGroupsList = new string[0] { }; 
    public DateTime dHireDate = DateTime.Parse("1999/11/03"), dTermDate = DateTime.Parse("01/01/0001"), dRateEffectiveDate = DateTime.Parse("2017 - 07 - 15"); 
    public decimal nPayRate = 1500; 
} 

    public class PostEmployeeClass 
{ 
    public int _interfaceID { get; set; } 
    public int _errorCode { get; set; } 
    public string _errorDescription { get; set; } 
    public List<EmpPostResponse> respList; 
} 

public class EmpPostResponse 
{ 
    public string RetKey { get; set; } 
    public int ErrorCode { get; set; } 
    public string Description { get; set; } 
    public string Success { get; set; } 
    public string SecondaryList { get; set; } 
} 


    static async Task<List<EmpPostResponse>> CallPostEmployeeAsync(object postdata) 
    { 
     Console.WriteLine("Post Employee Process Started"); 
     PostEmployeeClass authclass = null; 
     List<EmpPostResponse> data = null; 
     HttpResponseMessage response = await client.PostAsJsonAsync("xxxxxxV2/api/ED907F98-9132-4C7D-B4D4-7648A2577F6D/Integration/employees", postdata); 
     response.EnsureSuccessStatusCode(); 

     if (response.IsSuccessStatusCode) 
     { 
      Console.WriteLine("success"); 
      authclass = await response.Content.ReadAsAsync<PostEmployeeClass>(); 

      data = authclass.respList; 
     } 
     else 
      Console.WriteLine("fail:" + response.StatusCode.ToString()); 

     return data; 
    } 
    static void Main(string[] args) 
    { 
     Console.WriteLine("Starting the Process"); 
     RunAsync().Wait(); 
    } 
    static async Task RunAsync() 
    { 
     PostEmpData objPost = new PostEmpData(); 
     client.BaseAddress = new Uri("https://xxxx.xxxxx.com/"); 
     client.DefaultRequestHeaders.Accept.Clear(); 
     client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 
     try 
     { 
      string AuthToken="XXXXXXXXXXXXX"; 
      client.DefaultRequestHeaders.Add("AuthToken", AuthToken); 

      Console.WriteLine(AuthToken); 

      var postdata = CallPostEmployeeAsync(objPost); 

     }catch(Exception ex) 
     { 
      Console.WriteLine(ex.ToString()); 
     }

我已阅读了您的代码，并且发现了一些我注意到的事情。

有一件事情不会奏效：PostEmpData将序列化为一个空对象，因为它不包含任何属性。所以身体会是这样的：{}。您需要为课程添加属性：

public class PostEmpData 
{ 
    public string cExternalGUID { get; set; } = "10134"; 
    public string cEmployeeID { get; set; } = "10134"; 
    public string cLastName { get; set; } = "Anderson"; 
    public string cFirstName { get; set; } = "Derek"; 
    public string cAccessGroup { get; set; } = ""; 
    public string cActive { get; set; } = "A"; 
    public int nCardNumber { get; set; } = 10134; 
    public int nPayMethod { get; set; } = 2; 
    public string[] cGroupsList { get; set; }= new string[0] { }; 
    public DateTime dHireDate { get; set; }= DateTime.Parse("1999/11/03"); 
    public DateTime dTermDate { get; set; }= DateTime.Parse("01/01/0001"); 
    public DateTime dRateEffectiveDate { get; set; }= DateTime.Parse("2017 - 07 - 15"); 
    public decimal nPayRate { get; set; }= 1500; 
} 

这很可能会导致未经授权的回复。而且它可能与令牌无关。

与邮递员请求相比，还有另一个区别。通过邮递员发送一个对象[{}]的数组，但通过代码发送一个对象。所以你可能不得不张贴PostEmpData的列表。
