oAuth2 RestClient 获取令牌不工作，即使 Postman 工作

Question

以下是在 Postman 中获取成功令牌所需的参数。

代币名称：Sage Access Token

授权类型：授权码

回调URL: https://dummyaddress

使用浏览器授权：未勾选

授权URL: https://dummyaddress

访问令牌URL：https://id.sage.com/oauth/token

客户端 ID：您的客户端 ID

客户端密码：您的客户端密码

范围：openid 配置文件电子邮件 offline_access

客户端身份验证：作为基本身份验证发送 header

当我尝试通过代码时，我得到了 UnAuthorized。

        var client = new RestClient("https://id.sage.com/oauth/token");
        var request = new RestRequest(Method.POST);
        request.AddHeader("cache-control", "no-cache");
        request.AddHeader("content-type", "application/x-www-form-urlencoded");
        //  request.AddParameter("application/x-www-form-urlencoded", "grant_type=Authorization_Code&client_id=DxpXMEWXW1oVjn5l4DwRuw9d0bRzpUlG&client_secret=MlUMsZINFBovHODAjmtfG8rO8kjVyiaDYgvfyeg1lmaMArC2ihyd1jh-5u2GyqU&Scope=openid profile email offline_access&Callback_URL=https://customerdataquestuk--sage--c.visualforce.com/apex/SageCode &Auth_URL=https://id.sage.com/authorize?audience=s200ukipd/sage200", ParameterType.RequestBody);
        request.AddParameter("Grant_Type", "Authorization Code");
        request.AddParameter("Callback_URL", "https://dummyaddress");
        request.AddParameter("Auth_URL", "https://dummyaddress");
        request.AddParameter("Client_ID", your client ID);
        request.AddParameter("Client_Secret", your client secret);
        request.AddParameter("Scope", "openid profile email offline_access");
        IRestResponse response = client.Execute(request);

Answer 1

您的代码中缺少基本身份验证 header，您可以使用以下 C# 代码手动创建基本身份验证 header：

var credentials = string.Format("{0}:{1}", clientId, clientSecret);
var headerValue = Convert.ToBase64String(Encoding.UTF8.GetBytes(credentials));

var client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", headerValue);

或者如果您使用 RestClient

var client = new RestClient("http://localhost");
client.Authenticator = new HttpBasicAuthenticator(clientId,clientSecret);
