获得雅虎接触，使用OAuth的android雅虎、OAuth、android

2023-09-05 00:14:44 作者：故事与你

这是我的code以获得在Android的雅虎接触。即时通讯能够获得高达访问令牌，但同时对接触使GET请求即时得到签名无效的错误。

我搜索了很多，但我不能找到什么即时做错了。所以任何人都帮我个忙。

解决方案

我固定与此code这个问题。关键是ü需要连接code所有钥匙和价值，然后连接$ C C的PARMS $了。。请记住，access_token当属$ P $笔codeD。

解决方案

i fixed this issue with this code. the trick is u need to encode all 'key' and 'values', then encode the parms again. . Remember that access_token comes as preencoded.

private void getAllContacts() {


    HttpClient httpclient = new DefaultHttpClient();

    String host_url = "http://social.yahooapis.com/v1/user/" + mUSER_GUID+ "/contacts";

    String nonce = ""+System.currentTimeMillis();
    String timeStamp = ""+(System.currentTimeMillis()/1000L);

    try{
        String params = 
                ""+encode("oauth_consumer_key")+"=" + encode(CONSUMER_KEY)
                + "&"+encode("oauth_nonce")+"="+encode(nonce)
                + "&"+encode("oauth_signature_method")+"="+encode("HMAC-SHA1")
                + "&"+encode("oauth_timestamp")+"="+encode(timeStamp)
                + "&"+encode("oauth_token")+"="+ACCESS_TOKEN
                + "&"+encode("oauth_version")+"="+encode("1.0")

                ;
        String baseString = encode("GET")+"&"+encode(host_url)+"&"+encode(params);
        String signingKey = encode(CONSUMER_SECRET)+"&"+encode(ACCESS_TOKEN_SECRET);
        VIPLogger.info(TAG, "base string: " + baseString);
        String lSignature = computeHmac(baseString, signingKey);
        VIPLogger.info(TAG, "signature: " + lSignature);
        lSignature = encode(lSignature);
        VIPLogger.info(TAG, "signature enacoded: " + lSignature);

        String lRequestUrl = host_url
                            + "?oauth_consumer_key="+CONSUMER_KEY
                            + "&oauth_nonce="+nonce
                            + "&oauth_signature_method=HMAC-SHA1"
                            + "&oauth_timestamp="+timeStamp
                            + "&oauth_token="+ACCESS_TOKEN
                            + "&oauth_version=1.0"
                            + "&oauth_signature="+lSignature
                            ;
        //VIPLogger.info(TAG, lRequestUrl.substring(1202));
        HttpGet httpget = new HttpGet(lRequestUrl);
        ResponseHandler<String> responseHandler = new BasicResponseHandler();
        String responseBody = httpclient.execute(httpget, responseHandler);

        VIPLogger.info(TAG, "contacts response: " + responseBody);
    }catch(Exception e){
        e.printStackTrace();
        VIPLogger.error(TAG, "error while fetching user contacts");
    }

}
