嗨，我正在尝试实现OAuth1.0以下本教程在本教程中，有一个标题OAuthGetRequestToken
在中，为了获得请求令牌，我们必须向URL
发送post请求www.google.com/accounts/OAuthGetRequestToken我在我的谷歌应用程序引擎的代码发送一个post请求我的代码是:

我在域名imehandirattaritesh.appspot.com上托管我的应用程序，我想可能我把我所有的参数都正确了。可能在教程链接签名是一个非常小的字符串，但在我的情况下，它是一个非常大的字符串，我把我的。pk8文件的内容，它是由证书。pem文件生成的。我希望我的输入像这样
oauth_token=ab3cd9j4ks73hf7g&oauth_token_secret=ZXhhbXBsZS5jb20&oauth_callback_confirmed=true
但是在这个地方，我得到了发送post请求的响应
signature_invalidbase_string:POST&https%3A%2F%2Fwww.google.com%2Faccounts%2FOAuthGetRequestToken&oauth_callback%3Dhttps%253A%252F%252Fimehandirattaritesh.appspot.com%252Fauthsub%26oauth_consumer_key%3Dimehandirattaritesh.appspot.com%26oauth_nonce%3D1357733037248%26oauth_signature_method%3DRSA-SHA1%26oauth_timestamp%3D1357733037%26oauth_version%3D1.0%26scope%3Dhttp%253A%252F%252Fwww.google.com%252Fcalendar%252Ffeeds
my oauth_callback is https://imehandirattaritesh.appspot.com/authsub
我正试图删除这个错误，但每次都失败了，请任何人帮助如何删除这个错误或资源或链接，我将得到任何帮助。请不要建议我使用java客户端OAuth1.0。我必须使用谷歌预测api，然后从我的应用程序和java客户端库中调用，没有与调用谷歌预测api相关的功能。请帮助我如何消除这个错误，并得到正确的输出
很明显签名无效。您的RSA密钥不是您的签名。请参考同一教程的签名请求来创建有效的签名。https://developers.google.com/accounts/docs/OAuth_ref SigningOAuth .
