OAuth的与Android [英] OAuth with Android

问题描述

我试图访​​问Yelp的API。我已经得到我的钥匙，看了大约40篇解释什么，我需要做的，我已经尝试了一切。关键的，哪些不是有效。我收到以下内容：

  05-16 17：39：54.955：E / AndroidRuntime（538）：java.lang.NoClassDefFoundError的：oauth.signpost.commonshttp.CommonsHttpOAuthConsumer
 

我已经导入了commons- codeC-1.6罐，路标，commonshttp4-1.2.1.2.jar和路标 - 核心1.2.1.2.jar。

我仍然得到错误信息。任何帮助吗？

解决方案

转到项目 - >属性，并根据您的Java构建路径 - >订单和出口标签确保这些JAR文件检查

和，只是以供将来参考，如果这些是你真正的钥匙，我会确保为不可以把它们放在公共网站上。只是在说。

I am attempting to access the Yelp API. I have obtained my keys and have read about 40 articles explaining what I need to do and I have attempted everything. The key and what not are valid. I am getting the following:

05-16 17:39:54.955: E/AndroidRuntime(538): java.lang.NoClassDefFoundError: oauth.signpost.commonshttp.CommonsHttpOAuthConsumer

I have imported the commons-codec-1.6 jar, the signpost-commonshttp4-1.2.1.2.jar, and the signpost-core-1.2.1.2.jar.

I am still getting the error message. Any help?

        String urlToPost = "http://api.yelp.com/v2/search";
        Map<String, String> myMap = new HashMap<String, String>();
        myMap.put(OAuth.OAUTH_CONSUMER_KEY, consumerKey);
        myMap.put(OAuth.OAUTH_TOKEN, token);

        myMap.put(OAuth.OAUTH_NONCE, "asdf");

        urlToPost = OAuth.addQueryParameters(urlToPost, myMap);

        HttpURLConnection myCon = (HttpURLConnection) (new URL(urlToPost)).openConnection();
        myConsumer.sign(myCon);

        myCon.connect();
        return myCon.getResponseMessage();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
  }
}

解决方案

Go to Project -> Properties, and under your Java Build Path -> Order and Export tab make sure those JARs are checked.

And, just for future reference, if those are your real keys, I would make sure to not put them on a public website. Just sayin.
