设置HttpClient的授权标头

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了设置HttpClient的授权标头相关的知识，希望对你有一定的参考价值。
我有一个HttpClient，我用于REST API。但是，我在设置Authorization标头时遇到问题。我需要将标头设置为我从执行OAuth请求时收到的令牌。我看到.NET的一些代码表明以下内容，
httpClient.DefaultRequestHeaders.Authorization = new Credential(OAuth.token);
但是，Credential类在WinRT中不存在。任何人有任何想法如何设置授权标头？
答案
所以这样做的方法如下，
httpClient.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("Bearer", "Your Oauth token");

6年后，但添加这个，以防它有助于某人。
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);
}
}
另一答案
使用AuthenticationHeaderValue类System.Net.Http汇编
public AuthenticationHeaderValue(
string scheme,
string parameter
)
我们可以为我们的Authorization设置或更新现有的httpclient标头，如下所示：
httpclient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", TokenResponse.AccessToken);
另一答案
UTF8选项
request.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue(
"Basic", Convert.ToBase64String(
System.Text.Encoding.UTF8.GetBytes(
$"{yourusername}:{yourpwd}")));
另一答案
这可能有用，如果你从服务接收json或xml，我想如果你使用函数MakeXmlRequest（把结果放在xmldocumnet中）和MakeJsonRequest，你可以让你知道标题和T类型是如何工作的。 （将json放在你想要的类中，与json响应具有相同的结构）
/*-------------------------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)
{
string wufooAPIKey = "";
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;
// request.Accept = "application/json";
// request.Method = "GET";
MakeRequest(
request,
(response) =>
{
if (successAction != null)
{
T toReturn;
try
{
toReturn = Deserialize<T>(response);
}
catch (Exception ex)
{
errorAction(ex);
return;
}
successAction(toReturn);
}
},
(error) =>
{
if (errorAction != null)
{
errorAction(error);
}
}
);
}
private void MakeRequest(HttpWebRequest request, Action<string> successAction, Action<Exception> errorAction)
{
try{
using (var webResponse = (HttpWebResponse)request.GetResponse())
{
using (var reader = new StreamReader(webResponse.GetResponseStream()))
{
var objText = reader.ReadToEnd();
successAction(objText);
}
}
}catch(HttpException ex){
errorAction(ex);
}
}
private T Deserialize<T>(string responseBody)
{
try
{
var toReturns = JsonConvert.DeserializeObject<T>(responseBody);
return toReturns;
}
catch (Exception ex)
{
string errores;
errores = ex.Message;
}
var toReturn = JsonConvert.DeserializeObject<T>(responseBody);
return toReturn;
}
}
}
另一答案
这可能有助于设置标题：
WebClient client = new WebClient();
string authInfo = this.credentials.UserName + ":" + this.credentials.Password;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
client.Headers["Authorization"] = "Basic " + authInfo;
另一答案
request.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue(
"Basic", Convert.ToBase64String(
System.Text.ASCIIEncoding.ASCII.GetBytes(
$"{yourusername}:{yourpwd}")));

我寻找一个处理这个问题的好方法，我正在寻找同样的问题。希望这个答案能帮助每个有同样问题的人都喜欢我。
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.
....
}

我同意TheWhiteRabbit的答案，但如果你使用HttpClient进行大量调用，我认为代码似乎有点重复。
我认为有两种方法可以改善答案。
创建一个帮助程序类来创建客户端：
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}
