我在写我自己的盒子SDK为WP8做出最出任务。 我无法获得访问令牌。 我总是得到这样的回报： 

{"error":"invalid_request","error_description":"Invalid grant_type parameter or parameter missing"}

代码（均在C＃）我使用的是： 

    internal const String TokenURL = "https://api.box.com/oauth2/token";

CloudHttpAsync.DownloadResponceStreamAsync
(
    CloudHttpAsync.PostAsync
    (
        TokenURL,
        new MemoryStream
        (
            UTF8Encoding.UTF8.GetBytes
            (
                HttpUtility.UrlEncode
                (
                    String.Format
                    (
                        "grant_type=authorization_code&code={0}&client_id={1}&client_secret={2}&redirect_uri={3}",
                        Code,
                        ClientID,
                        ClientSecret,
                        RedirectURI
                    )
                )
            )
        ),
        null,
        null
    ),
    null
).ContinueWith((AsyncStream) =>
    {
        try
        {
            if (AsyncStream.Exception != null)
            {
                TaskSource.TrySetException(AsyncStream.Exception.InnerExceptions);
                return;
            }

            String Result = "";
            using (StreamReader Reader = new StreamReader(AsyncStream.Result))
            {
                Result = Reader.ReadToEnd();
            }

            BoxAuthToken Token = JsonConvert.DeserializeObject<BoxAuthToken>(Result);
            TaskSource.TrySetResult(Token);
        }
        catch (Exception e)
        {
            TaskSource.TrySetException(e);
        }
    });

对不起有大量的代码，我喜欢一般写:)

Answer 1:

这不是盒API文档上的任何地方上市，但是对于检索访问令牌的请求需要头Content-Type: application/x-www-form-urlencoded

我还停留在这一部分一段时间，直到我发现StackOverflow的答案。 我忘了链接到它虽然。



Answer 2:

请求/响应将是有益的。 它看起来像你的URL编码整个查询字符串，而不是仅仅每个值。 这将提交给我们：grant_type％3Dauthorization_code％26code％3Dxyz％26client_id％3Dxyz％26client_secret％3Dxyz％26redirect_uri％3Dxyz

代替：grant_type = authorization_code＆代码= XYZ＆CLIENT_ID = XYZ＆client_secret = XYZ＆REDIRECT_URI = XYZ



Answer 3:

我认为，包括redirect_uri在你的请求主体可能是复杂的东西，特别是因为它看起来被设置为无效值（ https://CloudBoxWP8 ）你可以通过设置你的应用程序来处理自定义协议（解决此cloudboxwp8:// ）和预先配置盒当令牌被授予重定向到。

  1. 注册自定义协议为您的WP8应用程序。 例如， cloudboxwp8 。
  2. 增加自己的WP8应用程序以处理对协议的一些端点的请求。 例如， cloudboxwp8://tokengranted 。 在这里实现你的令牌处理逻辑。
  3. 编辑您的盒子的应用程序和浏览到的OAuth2 paramters部分（通过管理箱应用程序 =>编辑应用程序）
  4. 在redirect_uri场，将该值设置为从步骤2中保存更改自定义的协议和端点。
  5. 取出redirect_uri从您的请求主体，并再次尝试您的请求。


Answer 4:

在Windows手机8.1的WinRT 

Dictionary<string, string> contentList = new Dictionary<string, string>();

contentList.Add("code", code);
contentList.Add("client_id", client_id);
contentList.Add("client_secret", clientSecret);
contentList.Add("redirect_uri", redirectUri);
contentList.Add("grant_type", "authorization_code");

FormUrlEncodedContent content = new FormUrlEncodedContent(contentList);

var response = await client.PostAsync(baseURL, content);
YouTubeAutenticationResponse res =       JsonConvert.DeserializeObject<YouTubeAutenticationResponse>(await     response.Content.ReadAsStringAsync());

public class YouTubeAutenticationResponse
{
    [JsonProperty("access_token")]
    public string AccessToken { get; set; }
    [JsonProperty("token_type")]
    public string TokenType { get; set; }
    [JsonProperty("expires_in")]
    public string ExpiresIn { get; set; }
    [JsonProperty("refresh_token")]
    public string RefreshToken { get; set; }
}
