我有我使用使用REST API一个HttpClient的。但是我无法建立Authorization头。我需要设置的头，我从做我的OAuth请求接收的令牌。我看到了.NET一些代码，提出以下建议，

httpClient.DefaultRequestHeaders.Authorization = new Credential(OAuth.token);

然而凭证类这是否不存在WinRT中。任何人有任何想法如何设置授权头？

Answer 1:

因此，要做到这一点的方法如下，

httpClient.DefaultRequestHeaders.Authorization =
    new AuthenticationHeaderValue("Bearer", "Your Oauth token");

Answer 2:

request.DefaultRequestHeaders.Authorization = 
    new AuthenticationHeaderValue(
        "Basic", 
        Convert.ToBase64String(
            System.Text.ASCIIEncoding.ASCII.GetBytes(
                string.Format("{0}:{1}", "yourusername", "yourpwd"))));

Answer 3:

我找了一个很好的方式来处理这个问题，我在看同样的问题。希望这个答案将帮助大家谁都有同样的问题，喜欢我。

using (var client = new HttpClient())
{
    var url = "https://www.theidentityhub.com/{tenant}/api/identity/v1";
    client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);
    var response = await client.GetStringAsync(url);
    // Parse JSON response.
    ....
}

从参考https://www.theidentityhub.com/hub/Documentation/CallTheIdentityHubApi

Answer 4:

我同意TheWhiteRabbit的答案，但如果你有很多使用的HttpClient调用的代码似乎有点在我看来重复。

我认为有2种方式，以提高回答了一下。

创建一个辅助类来创建客户端：

public static class ClientHelper
{
    // Basic auth
    public static HttpClient GetClient(string username,string password)
    {
            var authValue = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.UTF8.GetBytes($"{username}:{password}")));

            var client = new HttpClient(){
                DefaultRequestHeaders = { Authorization = authValue}
                //Set some other client defaults like timeout / BaseAddress
            };
            return client;
    }

    // Auth with bearer token
    public static HttpClient GetClient(string token)
    {
            var authValue = new AuthenticationHeaderValue("Bearer", token);

            var client = new HttpClient(){
                DefaultRequestHeaders = { Authorization = authValue}
                //Set some other client defaults like timeout / BaseAddress
            };
            return client;
    }
}

用法：

using(var client = ClientHelper.GetClient(username,password))
{
    //Perform some http call
}

using(var client = ClientHelper.GetClient(token))
{
    //Perform some http call
}

创建一个扩展方法：

没有赢得美奖，但伟大工程:)

    public static class HttpClientExtentions
    {
        public static AuthenticationHeaderValue ToAuthHeaderValue(this string username, string password)
        {
            return new AuthenticationHeaderValue("Basic",
        Convert.ToBase64String(
            System.Text.Encoding.ASCII.GetBytes(
                $"{username}:{password}")));
        }
    }

用法：

using (var client = new HttpClient())
{
    client.DefaultRequestHeaders.Authorization = _username.ToAuthHeaderValue(_password); 
}

再次，我觉得2个以上选项中做出using语句少一点重复的客户端。请记住，这是重用HttpClient的，如果你正在多个HTTP调用最好的做法，但我认为这是一个有点超出范围了这个问题。

Answer 5:

由于这是一个很好的做法重用HttpClient的实例 ，对性能和端口耗尽的问题 ，因为没有一个答案给这个解决方案（甚至导致你走向不好的做法:(），我把这里对我做出了回答链接在一个类似的问题：

Answer 6:

要设置基本身份验证使用C＃的HttpClient。下面的代码为我工作。

   using (var client = new HttpClient())
        {
            var webUrl ="http://localhost/saleapi/api/";
            var uri = "api/sales";
            client.BaseAddress = new Uri(webUrl);
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            client.DefaultRequestHeaders.ConnectionClose = true;

            //Set Basic Auth
            var user = "username";
            var password = "password";
            var base64String =Convert.ToBase64String( Encoding.ASCII.GetBytes($"{user}:{password}"));
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",base64String);

            var result = await client.PostAsJsonAsync(uri, model);
            return result;
        }

Answer 7:

这就是我已经做到了：

using (HttpClient httpClient = new HttpClient())
{
   Dictionary<string, string> tokenDetails = null;
   var messageDetails = new Message { Id = 4, Message1 = des };
   HttpClient client = new HttpClient();
   client.BaseAddress = new Uri("http://localhost:3774/");
   var login = new Dictionary<string, string>
       {
           {"grant_type", "password"},
           {"username", "sa@role.com"},
           {"password", "lopzwsx@23"},
       };
   var response = client.PostAsync("Token", new FormUrlEncodedContent(login)).Result;
   if (response.IsSuccessStatusCode)
   {
      tokenDetails = JsonConvert.DeserializeObject<Dictionary<string, string>>(response.Content.ReadAsStringAsync().Result);
      if (tokenDetails != null && tokenDetails.Any())
      {
         var tokenNo = tokenDetails.FirstOrDefault().Value;
         client.DefaultRequestHeaders.Add("Authorization", "Bearer " + tokenNo);
         client.PostAsJsonAsync("api/menu", messageDetails)
             .ContinueWith((postTask) => postTask.Result.EnsureSuccessStatusCode());
      }
   }
}

Answer 8:

使用基本授权和JSON参数。

using (HttpClient client = new HttpClient())
                    {
                        var request_json = "your json string";

                        var content = new StringContent(request_json, Encoding.UTF8, "application/json");

                        var authenticationBytes = Encoding.ASCII.GetBytes("YourUsername:YourPassword");

                        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
                               Convert.ToBase64String(authenticationBytes));
                        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

                        var result = await client.PostAsync("YourURL", content);

                        var result_string = await result.Content.ReadAsStringAsync();
                    }

Answer 9:

使用AuthenticationHeaderValue类的System.Net.Http组装

public AuthenticationHeaderValue(
    string scheme,
    string parameter
)

我们可以设置或更新现有Authorization头为我们httpclient像这样：

httpclient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", TokenResponse.AccessToken);

Answer 10:

6年后但如果添加此它可以帮助别人。

https://www.codeproject.com/Tips/996401/Authenticate-WebAPIs-with-Basic-and-Windows-Authen

var authenticationBytes = Encoding.ASCII.GetBytes("<username>:<password>");
using (HttpClient confClient = new HttpClient())
{
  confClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", 
         Convert.ToBase64String(authenticationBytes));
  confClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(Constants.MediaType));  
  HttpResponseMessage message = confClient.GetAsync("<service URI>").Result;
  if (message.IsSuccessStatusCode)
  {
    var inter = message.Content.ReadAsStringAsync();
    List<string> result = JsonConvert.DeserializeObject<List<string>>(inter.Result);
  }
}

Answer 11:

我设置了承载令牌

httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

它是在一个端点的工作，而不是其他。问题是，我不得不小写b的"bearer" 。变更后，现在它适用于这两种API的我打。这样一件容易的事情错过，如果你不甚至考虑它的草堆中寻找针的一个。

确保有"Bearer" -资本。

Answer 12:

这可以帮助设置页眉：

WebClient client = new WebClient();

string authInfo = this.credentials.UserName + ":" + this.credentials.Password;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
client.Headers["Authorization"] = "Basic " + authInfo;

Answer 13:

这可能工作，如果您收到一个JSON或从服务的XML，我认为这可以给大家介绍一下头和T型的工作原理也一样，如果你使用的功能MakeXmlRequest（把结果xmldocumnet）的想法和MakeJsonRequest （把JSON在您希望具有相同的结构，该JSON响应类）在接下来的方式

/*-------------------------example of use-------------*/
MakeXmlRequest<XmlDocument>("your_uri",result=>your_xmlDocument_variable =     result,error=>your_exception_Var = error);

MakeJsonRequest<classwhateveryouwant>("your_uri",result=>your_classwhateveryouwant_variable=result,error=>your_exception_Var=error)
/*-------------------------------------------------------------------------------*/


public class RestService
{
    public void MakeXmlRequest<T>(string uri, Action<XmlDocument> successAction, Action<Exception> errorAction)
    {
        XmlDocument XMLResponse = new XmlDocument();
        string wufooAPIKey = ""; /*or username as well*/
        string password = "";
        StringBuilder url = new StringBuilder();
        url.Append(uri);
        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url.ToString());
        string authInfo = wufooAPIKey + ":" + password;
        authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
        request.Timeout = 30000;
        request.KeepAlive = false;
        request.Headers["Authorization"] = "Basic " + authInfo;
        string documento = "";
        MakeRequest(request,response=> documento = response,
                            (error) =>
                            {
                             if (errorAction != null)
                             {
                                errorAction(error);
                             }
                            }
                   );
        XMLResponse.LoadXml(documento);
        successAction(XMLResponse);
    }



    public void MakeJsonRequest<T>(string uri, Action<T> successAction, Action<Exception> errorAction)
