https://api.twitter.com/oauth/request_token黑莓原生SDK失败

Question

我正试图通过oAuth连接到Twitter。我正在向API发出POST请求https://api.twitter.com/oauth/request_token.

这是我的Base签名字符串示例

POST&https%3A%2F%2Fapi.twitter.com%2Foauth%2Frequest_token&oauth_callback%3Dhttp%253A%252F%252Fapi.ec2.phunware.com%252Fapi%252Ftwitter%26oauth_consumer_key%3D6jq5dNZcccoPbApAJ0sOaA%26oauth_nonce%3DN2ZiMjViYzhlMDUxNDIyZWIwYjQ4NmU0ZjM1MDg4NTY%3D%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1362843354%26oauth_version%3D1.0

我用过这个工具http://quonos.nl/oauthTester/验证我的基本签名。

这里是对应的标题

OAuth oauth_callback="http%3A%2F%2Fapi.ec2.phunware.com%2Fapi%2Ftwitter",oauth_consumer_key="6jq5dNZcccoPbApAJ0sOaA",oauth_nonce="N2ZiMjViYzhlMDUxNDIyZWIwYjQ4NmU0ZjM1MDg4NTY=",oauth_signature_method="HMAC-SHA1",oauth_signature="7ney2RxElbHUl2t1Jnz57pQpmFs%3D",oauth_timestamp="1362843354",oauth_version="1.0" 

我在我的MAC终端中尝试了以下命令

curl --request 'POST' 'https://api.twitter.com/oauth/request_token' --header 'Authorization: OAuth oauth_callback="http%3A%2F%2Fapi.ec2.phunware.com%2Fapi%2Ftwitter",oauth_consumer_key="6jq5dNZcccoPbApAJ0sOaA",oauth_nonce="N2ZiMjViYzhlMDUxNDIyZWIwYjQ4NmU0ZjM1MDg4NTY=",oauth_signature_method="HMAC-SHA1",oauth_signature="7ney2RxElbHUl2t1Jnz57pQpmFs%3D",oauth_timestamp="1362843354",oauth_version="1.0"' --verbose

我得到401未经授权的错误。我试图设置oauth_callback="oob"，但我仍然得到同样的错误。

请帮助。我正在使用Blackberry NativeSDK编码。我在这里粘贴代码。当我尝试通过Blackberry 10.1 Simulator时，我得到204错误。

您提到您正在使用NativeSDK，您是否也在使用Cascades？如果是这样，您可能会更幸运地使用GitHub的bb-cascades-oauth库。它内置了对OAuth1和OAuth2的支持。

此外，根据这里的提示，错误的时间戳可能是一个常见问题，因此请确保您的模拟器具有正确的日期和时间。

另一位开发人员发现http://quonos.nl/oauthTester/需要一个不正确的双转义标头，并在发出实际身份验证请求时导致401个错误。我注意到您使用了相同的测试仪，并且上面的基本签名字符串中也有双转义，因此您可能希望尝试不使用双转义。
