即使访问令牌成功，我也会在 Get() 异步方法中收到未经授权的 401

Question

目前我必须异步方法 Post(( & Get((。对于我的 Post(( 方法返回一个访问令牌，如果您查看我的 post 方法的底部，我也在其中调用我的 Get((，原因很简单，能够在我的 get 中调用字符串结果。但即使访问令牌成功，我也不断收到 401 未经授权的状态代码，为什么？

缺少以下内容：

client.DefaultRequestHeaders.Add("Authorization", "Bearer " + Accesstoken);

这是您的默认标头，一旦您插入它，您就可以从您的 URL 获取字符串数据......

代码将如下所示：

 public async Task<string> Get(string Accesstoken)
    {
         string res = "";
         using (var client = new HttpClient())
        {
            Accesstoken = Accesstoken.Substring(17, 28);
            client.BaseAddress = new Uri("https://api.elliemae.com/");
            client.DefaultRequestHeaders.Add("Authorization", "Bearer " + Accesstoken);
            var response = client.GetAsync("encompass/v1/loans/ea7c29a6-ee08-4816-99d2-fbcc7d15731d").Result;
            using (HttpContent content = response.Content)
            {
                // ... Read the string.
                Task<string> result = content.ReadAsStringAsync();
                res = result.Result;
            }
