Question

尝试使用RestSharp在我的Web API上查询/token。

在Fiddler中我可以编写查询，它执行没有问题： 1.将方法设置为POST 2.添加标题：Content-Type: application/x-www-form-urlencoded 3.将Body设置为：username = username＆amp; password = pass＆amp; grant_type = password

试图在RestSharp中模仿这个：

RestClient tokenClient = new RestClient();
tokenClient.BaseUrl = new Uri(GlobalSettings.WebApiTokenUrl);
RestRequest req = new RestRequest(Method.POST);
req.AddHeader("Content-Type", "application/x-www-form-urlencoded");

//req.Parameters.Add(new Parameter() { Name = "username", Value = User.Identity.Name, Type = ParameterType.RequestBody, ContentType= "application/x-www-form-urlencoded" });
//req.Parameters.Add(new Parameter() { Name = "password", Value = User.Identity.Name, Type = ParameterType.RequestBody, ContentType = "application/x-www-form-urlencoded" });
//req.Parameters.Add(new Parameter() { Name = "grant_type", Value = "password", Type = ParameterType.RequestBody, ContentType = "application/x-www-form-urlencoded" });
//req.Parameters.Add(new Parameter() { Name = "response_type", Value = "token", Type = ParameterType.RequestBody, ContentType = "application/x-www-form-urlencoded" });
req.AddParameter(new Parameter() { Name = "username", Value = User.Identity.Name, Type = ParameterType.RequestBody, ContentType = "application/x-www-form-urlencoded" });
req.AddParameter(new Parameter() { Name = "password", Value = User.Identity.Name, Type = ParameterType.RequestBody, ContentType = "application/x-www-form-urlencoded" });
req.AddParameter(new Parameter() { Name = "grant_type", Value = "password", Type = ParameterType.RequestBody, ContentType = "application/x-www-form-urlencoded" });
//req.AddParameter(new Parameter() { Name = "response_type", Value = "token", Type = ParameterType.RequestBody });


IRestResponse response = tokenClient.Execute(req);

var content = response.Content;
// I get: {"error":"unsupported_grant_type"}

为什么这不起作用的任何想法？另外，为什么Paramter对象中有ContentType参数？我以为应该在标题中设置ContentType？（我也尝试从参数中删除ContentType）

看看是否有效。

     request.AddParameter("Content-Type", "application/x-www-form-urlencoded", ParameterType.HttpHeader);
     string encodedBody = string.Format("username={0}&password= {1}&grant_type={2}", User.Identity.Name, User.Identity.Name,password);
     request.AddParameter("application/x-www-form-urlencoded", encodedBody, ParameterType.RequestBody);
