joauth 是 Java 实现用来解析和验证 OAuth 请求的类库。

• Supports OAuth 1.0a and 2.0
• Uses thrust.HttpRequest, which can be used to wrap HttpServletRequests or other HTTP Request representations
• Unpacks Requests, extracts and verifies OAuth parameters from headers, GET, and POST
• Incidentally parses Non-OAuth GET and POST parameters and makes them accessible via a callback
• Custom callbacks to obtain scheme and path from the request in a non-standard way
• Configurable timestamp checking
• Correctly works around various weird URLEncoder bugs in the JVM
• Written in Scala, but should work pretty well with Java

示例代码：

import com.推ter.joauth.{Verifier, VerifierResult}    val verify = Verifier()  verify(oAuth1Request, tokenSecret, consumerSecret) match {    case VerifierResult.BAD_NONCE => // handle bad nonce    case VerifierResult.BAD_SIGNATURE => // handle bad signature    case VerifierResult.BAD_TIMESTAMP => // handle bad timestamp    case VerifierResult.OK => //success!  }
