尽管我得到了“代码”，但仍然在 vimeo api 上得到“invalid_client”

Question

我得到了代码，但在显示“invalid_client”的代码下方运行此代码。我在 Spotify 上测试了。

{
  "error":"invalid_client",
  "error_description":"A valid client ID must be provided along with any request made to Vimeo's API"
}

var SpotifyUrl = "https://api.vimeo.com/oauth/authorize?client_id=" + Uri.EscapeDataString("7......e96c30f") + " &response_type=code&redirect_uri=" + Uri.EscapeDataString("http://localhost:8888/callback") + "&state=xyzbc&show_dialog=true";
            var StartUri = new Uri(SpotifyUrl);
            var EndUri = new Uri("http://localhost:8888/callback");

var postData = new List<KeyValuePair<String, String>>();
            postData.Add(new KeyValuePair<String, String>("grant_type", "authorization_code"));
            postData.Add(new KeyValuePair<String, String>("code", code));
            postData.Add(new KeyValuePair<String, String>("redirect_uri", Uri.EscapeDataString("http://localhost:8888/callback")));
            postData.Add(new KeyValuePair<String, String>("client_id", clientid));     
            HttpContent content = new FormUrlEncodedContent(postData);
            String response = "";
            try
            {
                var data = await client.PostAsync("https://api.vimeo.com/oauth/access_token", content);
                byte[] result =  data.Content.ReadAsByteArrayAsync().Result;
                response = Encoding.UTF8.GetString(result, 0, result.Length);
            }

我相当确定您的问题是您添加到 client_id 的尾随空格...

（向右滚动，我已经指明了地点）

var SpotifyUrl = "https://api.vimeo.com/oauth/authorize?client_id=" + Uri.EscapeDataString("7......e96c30f") + " &response_type=code&redirect_uri=" + Uri.EscapeDataString("http://localhost:8888/callback") + "&state=xyzbc&show_dialog=true";
----------------------------------------------------------------------------------------------------------------^

这将在 client_id 的末尾附加一个 %20（空格）
