This line

<pre class="lang-cs prettyprint-override"><code>client.DefaultRequestHeaders.Authorization = 
 new AuthenticationHeaderValue(authValue.Parameter);
</code></pre>

Will produce this header value

<pre><code>Authorization: ACCESS_TOKEN
</code></pre>

Where <code>ACCESS_TOKEN</code> is the value of <code>authValue.Parameter</code>. You want to assign the value you passed instead to get the required header

<pre class="lang-cs prettyprint-override"><code>client.DefaultRequestHeaders.Authorization = authValue;
</code></pre>

Will produce

<pre><code>Authorization: OAuth2 ACCESS_TOKEN
</code></pre>

blocks|key|14108|text|我为此而苦苦挣扎。我一直收到“无效格式”的错误，因为我有一个自定义的实现，Authorization头是根据某些标准进行验证的。但是，以这种方式添加头文件是可行的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|14109|var+http+=+new+HttpClient();

I struggled with this. I kept getting an error saying "invalid format" because I have a custom implementation and the Authorization header is validated against certain standards. Adding the header this way however worked:

<pre><code>var http = new HttpClient();
http.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "key=XXX");
</code></pre>

Had a similar issue when getting AuthenticationHeaderValue to work with my requests.
I was also using JWT JsonWebToken from GitHub.
I was able to get a token from the API, but was struggling to use it in other GETs and POSTs.

<pre><code>var jwt = JsonWebToken.Encode(token, APISECRET, JwtHashAlgorithm.HS256);
var tk = GetTokenFromApi(); // basically returns an encrypted string.
</code></pre>

Manually using WebRequest:
Which worked fine.

<pre><code>request.ContentType = "application/json";
request.Method = "POST";
request.Headers.Set("Authorization", string.Format("Bearer {0}", tk));
</code></pre>

When we switched to an HttpClient, and used the AuthenticationHeaderValue, could not figure out how to set it up correctly.After looking at the request string, i saw it added the "Authorization" for me. Played around with parameters, and this finally this worked.

<pre><code> var authenticationHeaderValue = new AuthenticationHeaderValue("Bearer", tk);
</code></pre>

Maybe intresting for other people. Since I searched on this for a long time. But you have to save your cookies also and give it with your next request. First this is how i got my authentication code and hold my cookies in a static variable (in the first time i call this method I give an empty value to token).

<pre><code> public static CookieContainer CookieContainer;
 public static async Task&lt;string&gt; Post&lt;TRequest&gt;( TRequest requestBody, string path, string token = "")
 {
 var baseUrl = new Uri($"urlFromApi");
 CookieContainer = new CookieContainer();
 using (var handler = new HttpClientHandler() { CookieContainer = CookieContainer })
 using(var client = new HttpClient(handler){BaseAddress = baseUrl})
 {
 client.DefaultRequestHeaders.ConnectionClose = false;
 if (!string.IsNullOrWhiteSpace(token))
 {
 client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", $"{token}");
 }
 ServicePointManager.FindServicePoint(client.BaseAddress).ConnectionLeaseTimeout = 60 * 1000; //1 minute using (var content = new ByteArrayContent(GetByteData(requestBody)))
 using (var content = new ByteArrayContent(GetByteData(requestBody)))
 {
 content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
 var response = await client.PostAsync(String.Empty, content);
 return await GetResponseContent(response);
 }
 }

 }
</code></pre>

After this if I do any request to the api I include the cookies (token is what you get from the first response as a result) 
 public static async Task Get(string path, string token = "")
 {

<pre><code> var baseUrl = $"https://innoviris-ai.collibra.com/rest/2.0{path}";
 using (var handler = new HttpClientHandler() { CookieContainer = CookieContainer })
 using (var client = new HttpClient(handler) {BaseAddress = new Uri(baseUrl)})
 {
 client.DefaultRequestHeaders.ConnectionClose = false;
 if (!string.IsNullOrWhiteSpace(token))
 {
 client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", $"{token}");
 }
 ServicePointManager.FindServicePoint(client.BaseAddress).ConnectionLeaseTimeout = 60 * 1000; //1 minute 

 var response = await client.GetAsync(String.Empty);
 return await GetResponseContent(response);
 }
 }
</code></pre>

blocks|key|14290|text|在你的代码中，你是这样做的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|14291|client.DefaultRequestHeaders.Authorization+=+new+AuthenticationHeaderValue("Bearer",+$"{token}");|code-block|syntax|javascript|14292|我认为在不使用字符串插值的情况下，下面的代码应该以相同的方式工作：|14293|client.DefaultRequestHeaders.Authorization+=+new+AuthenticationHeaderValue("Bearer",+token);|14294|这是因为字符串插值只是生成一个包含令牌的字符串！|14295|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

In your code you are doing this:
<pre><code>client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(&quot;Bearer&quot;, $&quot;{token}&quot;);
</code></pre>
I think the following should work the same manner without using string interpolation:
<pre><code>client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(&quot;Bearer&quot;, token);
</code></pre>
This is because the string interpolation is just generating a string with the token in it!

I have the following code:

<pre><code>...
AuthenticationHeaderValue authHeaders = new AuthenticationHeaderValue("OAuth2", Contract.AccessToken);
string result = await PostRequest.AuthenticatedGetData(fullUrl, null, authHeaders);
return result; 
...

public static async Task&lt;string&gt; AuthenticatedGetData(string url, FormUrlEncodedContent data, AuthenticationHeaderValue authValue)
{

 HttpClient client = new HttpClient();
 client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(authValue.Parameter);

 HttpResponseMessage response = await client.PostAsync(new Uri(url), data);

 response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
 response.EnsureSuccessStatusCode();
 string responseBody = await response.Content.ReadAsStringAsync();
 return responseBody;
}
</code></pre>

The response = await part just continues an ongoing loop and nothing happens. Any ideas what I am doing wrong?

The question really is, how do I send the following header:

<pre><code>Authorization: OAuth2 ACCESS_TOKEN
</code></pre>

to an external web api

Adding authorization to the headers

我有以下代码：...AuthenticationHeaderValue authHeaders = new AuthenticationHeaderValue("OAuth2", Contract.AccessToken);string result = await PostRequest.AuthenticatedG...
