在代码中发布到Web API返回“未授权”

Question

我正在尝试发布到使用基本身份验证的Web API。当我使用Fiddler进行POST时，我能够成功发布数据。现在我试图在C＃控制台应用程序中做同样的事情，但我仍然得到401未经授权的响应。

当我通过调试运行代码时，我可以播种凭证正在正确获取Base64编码。在网上做一些研究，我相信我有正确的代码。任何人看到我是否错过了什么？

if (lstEmployee != null && lstEmployee.Count > 0) 
{ 
    try 
    { 
     using (var client = new HttpClient()) 
     { 
      client.BaseAddress = new Uri("https://website.com/api/employees/upload";); 


      //set credentials and add them to the client header 
      string credentials = Convert.ToBase64String(Encoding.Default.GetBytes("username:password"));  
      client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", credentials); 


      //set to use JSON 
      client.DefaultRequestHeaders.Clear(); 
      client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 


      foreach (var employee in lstEmployee) 
      { 
       //Convert to JSON with Newtonsoft 
       string employeeJSON = JsonConvert.SerializeObject(employee); 


       HttpResponseMessage response = client.PostAsJsonAsync(fullServiceURL, employeeJSON).Result; 


       if (response.IsSuccessStatusCode) 
       { 
        //If successfull, do something. 

       } 
       else 
       { 
        logger.Error("Error posting to Web API. Employee: {0} | {1} ({2})", employee.EmployeeNumber, (int)response.StatusCode, response.ReasonPhrase); 
       } 
      } 
     } 
    } 
    catch (Exception ex) 
    { 
     logger.Error("Error posting to Web API. | {0} | Trace: {1}", ex.Message, ex.StackTrace); 
    } 
} 
else 
{ 
    logger.Info("No records found."); 
} 

在菲德勒我只是添加了以下到作曲家选项卡中的头与身体中的一些JSON数据一起和它的工作。

Authorization: Basic abChaXJ3YXlzLmludGVncmF0aW9uOnRlc3Q0ZGNhYTIwMTU= 
Host: services.website.com 
Content-Length: 374 
Content-Type: application/json; charset=utf-8 

**更新**

我调整了代码如下。现在，我收到错误状态400“错误请求”。它似乎在抱怨数据格式不正确。但是，我记录了JSON列表值并将其添加到Fiddler的主体中。我可以在Fiddler中发布捕获的JSON就好了。我不知道还有什么要检查的，看看它有什么问题。

这是我的JSON列表经过Newtonsoft后的结果。我只拉用于测试目的

[{"EmployeeNumber":"22449","CompanyHireDate":"2014-12-15T00:00:00","Username":"EN022449","LastName":"AVIVA","FirstName":"JOE","MiddleInitial":null,"BirthDate":"1967-10-06T00:00:00","PhoneNumber":null,"EmailAddress":"EN999-Joe.Aviva@company.com","Location":"BOS","Address1":null,"Address2":null,"City":null,"State":null,"Zip":null,"OverrideSeniorityOrder":0}] 

这是我更新的代码的一个记录：

if (lstEmployee != null && lstEmployee.Count > 0) 
{ 
    logger.Info("Employee count: " + lstEmployee.Count); 

    string baseUrl = "https://services.website.com/api/"; 
    string serviceUrl = "employees/upload"; 

    string fullServiceURL = baseUrl + serviceUrl; 
    logger.Debug("Web API Uri: " + fullServiceURL); 

    try 
    { 
     //Convert the list to JSON 
     string employeeJSON = JsonConvert.SerializeObject(lstEmployee); 
     logger.Debug("employeeJSON: " + employeeJSON); 

     //Add credentials to Client Handler 
     var credentials = new NetworkCredential("username", "password"); 
     var handler = new HttpClientHandler { Credentials = credentials }; 

     using (var client = new HttpClient(handler)) 
     { 
      //set URI and to use JSON 
      client.BaseAddress = new Uri(fullServiceURL); 
      client.DefaultRequestHeaders.Clear(); 
      client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

      HttpResponseMessage response = client.PostAsJsonAsync(fullServiceURL, employeeJSON).Result; 
      if (response.IsSuccessStatusCode) 
      { 
       //success 
      } 
      else 
      { 
       logger.Error("Error posting to Web API. {0} ({1})", (int)response.StatusCode, response.ReasonPhrase); 
      } 
     } 
    } 
    catch (Exception ex) 
    { 
     logger.Error("Error posting to Web API. | {0} | Trace: {1}", ex.Message, ex.StackTrace); 
    } 
} 
else 
{ 
    logger.Info("No records found."); 
}

的HttpClientHandler，在.NET 4.5介绍，从有手工编码认证头为您节省。像这样使用它：

var credentials = new NetworkCredential(userName, password); 
var handler = new HttpClientHandler { Credentials = credentials }; 
using (var http = new HttpClient(handler)) 
{ 
    // ... 
}
