好的,所以,我正在为Android制作Tumblr客户端,我一直在尝试并且未能让OAuth工作一周左右。以下是它的发展方式:

用户启动应用。主要活动onCreate这样做:

settings = getSharedPreferences(PREFS_NAME, 0);
authToken=settings.getString("OauthToken", "none");
authTokenSecret=settings.getString("OauthSecret", "none");
if(authToken=="none" || authTokenSecret=="none"){
    Intent i = new Intent(getApplicationContext(),Authentication.class);
    startActivity(i);
}

这将启动包含WebView的身份验证活动。该活动成功获取请求令牌,并将WebView发送到Tumblr登录屏幕。要求用户允许应用访问他们的数据,他们按下允许,然后我的WebViewClient捕获回调URL,并使用它执行此操作:

String[] token = helper.getVerifier(url);
            if (token != null) {
                try {
                    String accessToken[] = helper.getAccessToken(token[1]);
                    editor.putString("OauthToken", accessToken[0]);
                    editor.putString("OauthSecret", accessToken[1]);
                    editor.commit();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            finish();

帮助程序类的getAccessToken和getVerifier看起来像这样:

public String[] getVerifier(String myUrl) {
    // extract the token if it exists
    Uri uri = Uri.parse(myUrl);
    if (uri == null) {
        return null;
    }

    String token = uri.getQueryParameter("oauth_token");
    String verifier = uri.getQueryParameter("oauth_verifier");
    return new String[] { token, verifier };
}

public String[] getAccessToken(final String verifier)
        throws OAuthMessageSignerException, OAuthNotAuthorizedException,
        OAuthExpectationFailedException, OAuthCommunicationException {
    new Thread(new Runnable() {
        public void run() {
                try {
                    mProvider.retrieveAccessToken(mConsumer, verifier);
                } catch (OAuthMessageSignerException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (OAuthNotAuthorizedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (OAuthExpectationFailedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (OAuthCommunicationException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
        }
    }).start();
    return new String[] {
            mConsumer.getToken(), mConsumer.getTokenSecret()
    };
}

然后我终于回到主应用程序屏幕并尝试进行我的第一次API调用,以获取用户仪表板上最近的十个帖子:

OAuthConsumer myConsumer = new CommonsHttpOAuthConsumer(MainView.authToken, MainView.authTokenSecret);
            HttpGet request = new HttpGet("http://api.tumblr.com/v2/user/dashboard?limit=10");
            myConsumer.sign(request);
            HttpClient httpClient = new DefaultHttpClient();
            HttpResponse response = httpClient.execute(request);
            HttpEntity entity = response.getEntity();
            BufferedReader reader = new BufferedReader(new InputStreamReader(entity.getContent()));
            String line;
            while ((line = reader.readLine()) != null) {
                builder.append(line);
            }

然而,我没有像我应该那样得到一个不错的JSON响应,而是得到了这个:

10-20 16:36:18.110: D/Result(22817): {"meta":{"status":401,"msg":"Not Authorized"},"response":[]}

那我哪里出错了?感谢

我已成功使用带有Appache HttpCommons GET / POST / PUT的路标库。

首先,我使用以下代码(ActivityLogin.java)启动了WebView以进行登录:

private static CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(AppConfig.CONSUMER_KEY, AppConfig.CONSUMER_SECRET);
private static OAuthProvider provider = new DefaultOAuthProvider (AppConfig.requestURL, AppConfig.accessURL, AppConfig.authURL);

private void logMeIn() throws ...{
    String authUrl = provider.retrieveRequestToken(consumer,AppConfig.CALLBACK_URL);
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
}

然后,我使用了onNewIntent(Intent)来接收先前发布的Activity的OAuth回调:

AppConfig.java代码snipet:

/** OAuth Authorization URL  */
public static final String authURL = mainOAuthUrl+"/authorize/?theme=android";

/** OAuth Request URL    */
public static final String requestURL = mainOAuthUrl+"/request/token/";

/** OAuth Access URL     */
public static final String accessURL = mainOAuthUrl+"/access/token/";

/** OAuth CALLback URL*/
public static final String CALLBACK_URL = "yourapp://twitt";

ActivityLogin.java代码snipet:

protected void onNewIntent(Intent intent) {
    Uri uri = intent.getData();
    if (uri != null && uri.toString().startsWith(AppConfig.CALLBACK_URL)) {  
        String verifier = uri.getQueryParameter(OAuth.OAUTH_VERIFIER);  

        provider.retrieveAccessToken(consumer, verifier);
        Data.OAuthAccessKey = consumer.getToken();
        Data.OAuthAccessSecret = consumer.getTokenSecret();
    }

}

然后,我的连接代码如下:

public HttpResponse sampleOauthConnect(String url) throws ...{

    /** setup some connection params */
    HttpContext context = new BasicHttpContext();

    HttpRequestBase request = new HttpGet(url);

    if (Data.OAuthConsumer == null)
        Data.OAuthConsumer = new CommonsHttpOAuthConsumer(AppConfig.CONSUMER_KEY, AppConfig.CONSUMER_SECRET);

    if (Data.OAuthAccessKey == null || Data.OAuthAccessSecret == null)
        throw new LoginErrorException(LoginErrorException.NOT_LOGGED_IN);

    Data.OAuthConsumer.setTokenWithSecret(Data.OAuthAccessKey, Data.OAuthAccessSecret);

    try {
        Data.OAuthConsumer.sign(request);
    } catch (OAuthMessageSignerException e) {
        throw new LoginErrorException(LoginErrorException.OAUTH_EXCEPTION, e);
    } catch (OAuthExpectationFailedException e) {
        throw new LoginErrorException(LoginErrorException.OAUTH_EXCEPTION, e);
    } catch (OAuthCommunicationException e) {
        throw new LoginErrorException(LoginErrorException.OAUTH_EXCEPTION, e);
    }

    HttpClient client = new DefaultHttpClient();

    /** finally execute this request */
    return client.execute(request, context);
}

目前,Tumblr不支持MultipartEntity,因此您必须使用NameValuePairs添加参数。

如果您想发布照片,您必须将该照片转换为ARRAY并对其进行网址编码!
