Question

在我的控制台应用程序中，我想刷新令牌，因为一个小时后令牌失效，我正尝试实现Refreshing a Token部分，我的代码如下：

 var client = new RestClient("https://login.microsoftonline.com/common/oauth2/v2.0/token");
 var request = new RestRequest(Method.POST);
 request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
 request.AddParameter("grant_type", "refresh_token");
 request.AddParameter("refresh_token", [My_Token]);
 request.AddParameter("client_id", [My_ClientId]);
 request.AddParameter("client_secret", [My_ClientSecret]);
 request.AddParameter("scope", "offline_access");
 request.AddParameter("redirect_uri", "urn:ietf:wg:oauth:2.0:oob");
 IRestResponse response = client.Execute(request);
 var content2 = response.Content;

但是我得到了答复：

{“错误”：“ invalid_request”，“错误描述”：“ AADSTS900144：请求正文必须包含以下参数：'refresh_token'。\ r \ n跟踪ID：56e56b4a-92b3-445a-9fcf-972b7a481300 \ r \ n关联ID：5cb2b84b-f128-4d4f-888c-6c9a3be1d70b \ r \ n时间戳：2019-05-16 13：01：57Z“，”错误代码“：[900144]，”时间戳“：” 2019-05-16 13:01 ：57Z“，” trace_id“：” 56e56b4a-92b3-445a-9fcf-972b7a481300“，” correlation_id“：” 5cb2b84b-f128-4d4f-888c-6c9a3be1d70b“}

PostSharp默认情况下以JSON或XML序列化主体。您需要GetOrPost来修复https://github.com/restsharp/RestSharp/wiki/ParameterTypes-for-RestRequest#getorpost

 request.AddParameter("grant_type", "refresh_token", ParameterType.GetOrPost);
 request.AddParameter("refresh_token", [My_Token], ParameterType.GetOrPost);
 request.AddParameter("client_id", [My_ClientId], ParameterType.GetOrPost);
 request.AddParameter("client_secret", [My_ClientSecret], ParameterType.GetOrPost);
 request.AddParameter("scope", "offline_access", ParameterType.GetOrPost);
 request.AddParameter("redirect_uri", "urn:ietf:wg:oauth:2.0:oob", ParameterType.GetOrPost);

@SergeyKovalev指出，您需要在参数中添加参数类型。

 request.AddParameter("refresh_token", [My_Token], ParameterType.GetOrPost);

此外，您不应该对内容类型使用表单编码，请尝试json

request.AddHeader("Content-Type", "application/json");

用restsharp刷新令牌
