c# - GoToWebinar - 请求不是预期格式 - RestSharp

Question

类似于此论坛帖子: https://developer.citrixonline.com/forum/request-not-expected-format

但是他并没有真正解释他发现他的代码有什么问题。

我正在使用 RestSharp 进行 API 调用。我已经能够很好地使用它来提取即将举行的网络研讨会的列表，但是当我尝试注册参与者时，我不断收到 400/Request not in expected format 错误。

遵循此文档 https://developer.citrixonline.com/api/gotowebinar-rest-api/apimethod/create-registrant ，这是我的代码:

var client = new RestClient(string.Format("https://api.citrixonline.com/G2W/rest/organizers/{0}/webinars/{1}/registrants", "300000000000xxxxxx", btn.CommandArgument));
var request = new RestRequest(Method.POST);
request.RequestFormat = DataFormat.Json;

request.AddHeader("Accept", "application/json");
request.AddHeader("Accept", "application/vnd.citrix.g2wapi-v1.1+json");
request.AddHeader("Authorization", "OAuth oauth_token=" + System.Configuration.ConfigurationManager.AppSettings["GoToWebinar"]);

request.AddParameter("firstName", LoggedInUser.FirstName);
request.AddParameter("lastName", LoggedInUser.LastName);
request.AddParameter("email", LoggedInUser.Email);

var response = client.Execute(request);
var statusCode = response.StatusCode;

关于我如何弄清楚为什么我不断收到该错误的任何见解？

谢谢!

而不是使用 AddParamter(它将键/值参数添加到请求主体)，您需要改为编写 JSON:

request.DataFormat = DataFormat.Json;
request.AddBody(new {
    firstName = LoggedInUser.FirstName,
    lastName = LoggedInUser.LastName,
    email = LoggedInUser.Email
});

如果您想直接指定它们，您还需要清除处理程序(它会自动设置 Accept header ):

client.ClearHandlers();
