设置HttpClient的授权头

我有一个HttpClient，我正在使用一个REST API。但是，我在设置授权标头时遇到了麻烦。我需要将标头设置为我从执行OAuth请求中接收到的令牌。我看到了一些。net的代码，建议如下:

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

然而，凭据类在WinRT中不存在。有人知道如何设置授权头吗?

当前回答

如果你想重用HttpClient，建议不要使用DefaultRequestHeaders，因为它们是用来发送每个请求的。

你可以试试这个:

var requestMessage = new HttpRequestMessage
    {
        Method = HttpMethod.Post,
        Content = new StringContent("...", Encoding.UTF8, "application/json"),
        RequestUri = new Uri("...")
    };

requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Basic", 
    Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes($"{user}:{password}")));

var response = await _httpClient.SendAsync(requestMessage);

方法是这样的，

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

在net .core中，您可以使用Identity Server 4

var client = new HttpClient();
client.SetBasicAuthentication(userName, password);

var client = new HttpClient();
client.SetBearerToken(token);

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

我在寻找一个好的方法来处理这个问题，我也在考虑同样的问题。希望这个答案能帮助到每个和我一样有同样问题的人。

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.
    ....
}
