我正在尝试使用Scribe在 Vimeo 中进行身份验证。事情进展不顺利。我不断收到错误代码 100，但它仍然给了我一个授权 URL，当我访问它时，我能够授予访问权限。只是当我输入授权码并尝试将请求令牌换成访问令牌时它不起作用。我正在使用 Facebook 示例并对其进行调整以与 Vimeo 一起使用。我真的不知道我在这里做什么。我之前问了一个问题，并被告知我需要包含apache commons 编解码器在我的类路径上。好吧，我将它包含在我的环境变量中，这并没有改变任何东西。所以我只是将它添加到我的项目库中，这似乎让我更进一步。现在我只是不知道从这里做什么。我不明白为什么我会得到这个。这是我的代码和输出：

public class VimeoTest
{
  private static final String NETWORK_NAME = "Vimeo";
  private static final Token EMPTY_TOKEN = null;

  public static void main(String[] args)
  {
    // Replace these with your own api key and secret
    String apiKey = "MYAPIKEY";
    String apiSecret = "MYAPISECRET";
    OAuthService service = new ServiceBuilder()
                                  .provider(VimeoApi.class)
                                  .apiKey(apiKey)
                                  .apiSecret(apiSecret)
                                  .debug()
                                  .build();
    Scanner in = new Scanner(System.in);

    System.out.println("=== " + NETWORK_NAME + "'s OAuth Workflow ===");
    System.out.println();
    OAuthRequest orequest = new OAuthRequest(Verb.GET, "http://vimeo.com/api/rest/v2");
    orequest.addQuerystringParameter("method", "vimeo.test.null");
    Response send = orequest.send();
    System.out.println(send.getBody());

    // Obtain the Authorization URL
    System.out.println("Fetching the Authorization URL...");
    Token requestToken = service.getRequestToken();

    String authorizationUrl = service.getAuthorizationUrl(requestToken);
    System.out.println("Got the Authorization URL!");
    System.out.println("Now go and authorize Scribe here:");

    //I do NOT want to have to do this. Is there any other way I can have this authorize without going to a web browser to do this?

    System.out.println(authorizationUrl);
    System.out.println("And paste the authorization code here");
    System.out.print(">>");
    Verifier verifier = new Verifier(in.nextLine());
    System.out.println();

    // Trade the Request Token and Verfier for the Access Token
    System.out.println("Trading the Request Token for an Access Token...");
    Token accessToken = service.getAccessToken(EMPTY_TOKEN, verifier);

    //****Breaks on the line above.****
    //I think it's because the orequest.send() returned a 100 error code
    //Note, EMPTY_TOKEN is declared as null, but I think that's ok. Verifier is not null.

    System.out.println("Got the Access Token!");
    System.out.println("(if your curious it looks like this: " + accessToken + " )");
    System.out.println();

这是输出：

编辑：将 .debug() 添加到 new ServiceBuilder() 并相应地更新了输出。

更改此行：

Token accessToken = service.getAccessToken(EMPTY_TOKEN, verifier);

为了：

Token accessToken = service.getAccessToken(requestToken, verifier);

编辑

整个关键未经授权的部分是因为这段代码：

OAuthRequest orequest = new OAuthRequest(Verb.GET, "http://vimeo.com/api/rest/v2");
orequest.addQuerystringParameter("method", "vimeo.test.null");
Response send = orequest.send();
System.out.println(send.getBody());

您正在尝试向 api 根发出 GET 请求（即使这是一个有效资源也不确定），但没有对其进行签名。当然，它会产生未经授权的错误。
