使用Java路标的Yelp V2 API-无效的\u签名

尝试从Java应用程序（Android）调用v2 api，利用 路标oauth图书馆。我已将代码提取到一个独立的 可以从命令行运行的版本（不依赖于 Android）。请看一看，让我知道我做错了什么

您可以通过键入：java-jar YelpV2Test.jar直接运行该示例 我还包括了一个zip文件，它是源代码，并且是必需的 库，设置为Eclipse项目。我还在粘贴代码 就在下面

我试着从GET换到POST，结果一模一样 结果。使用v1api没有问题。解决这个问题有什么帮助吗 将不胜感激

--代码的开始--

--代码结束--

我看到的测试结果如下：

$java-jar YelpV2Test.jar

RunMe>>签名查询：

运行时>>结果：{“错误”：{“文本”：“签名无效” 无效，“id”：“无效的签名”，“说明”：“无效的签名”。 预期的签名基字符串：GET&http%3A%2F%2Fapi.yelp.com %2Fv2%2搜索和分类过滤器%3Dbanks%26限制%3D15%26ll %3D30.361471%252C-87.164326%26oauth\u用户密钥 %3dpbsjw9p08到当前的%26oauth %3D483128657125973388%26oauth_签名法%3DHMAC- SHA1%26oauth_时间戳%3D1296021631%26oauth_令牌 %3DARfbDucxkBi89lBHARTgygLkcMw9h8eW%26oauth_版本%3D1.0%26offset

你找到解决方案了吗？？？？？我最后使用了另一个库。在Android上使用路标时出现了一些bug。现在可能已经修好了，我不确定。你用的是什么库？我用的是scribe oauth java库。见：
