使用固定登录更容易，不需要Oauth2尽管手动执行Oauth2并不难，只要将令牌转换为承载身份验证头…

我想知道是否是这样，但是查看类需要的参数，我不知道应该传递什么值，而且看起来太复杂了。我有用户的访问令牌，当然我所需要做的就是将其包含在对API的请求中（正如这里“使用访问令牌”部分所暗示的：，尽管没有说明如何使用.NET客户端库）。我希望我刚开始使用REST API，但是当我发布我的问题时，我已经投资了.NET客户端库！我终于让它工作了——请看我发布的答案。另外，我很想使用OAuth，因为我将有多个用户访问我的应用程序，我希望他们能够像自己一样从API读/写API。但是，如果您能告诉我如何在Ajax调用中成功地传递OAuth访问令牌（可以通过PAT来实现，但无法理解访问令牌），您将是我的英雄！从未听说过PAT tbh：（在C#中，使用HttpClient它是

HttpClient.DefaultRequestHeaders.Authorization=new AuthenticationHeaderValue（“承载人”，“您的Oauth令牌”）；
