ios - JWT 'DecodeResult' 没有名为 'Success' 的成员

Question

我正在尝试使用 Swift JWT pod解码 JWT token 。

// Get and decode the response
    var response = NSURLConnection.sendSynchronousRequest(request, returningResponse: AutoreleasingUnsafeMutablePointer<NSURLResponse?>(), error: NSErrorPointer())
    let responseContent = NSString(data:response!, encoding:NSUTF8StringEncoding)

    let decoded = JWT.decode(responseContent! as String, .HS256(secret))

    println(decoded.Success)

此代码出现错误:

'DecodeResult' does not have a member named 'Success'

看起来 DecodedResult 有一个 Enum:https://github.com/kylef/JSONWebToken.swift/blob/master/JWT/Decode.swift#L50

我怎样才能访问其中的有效负载？

您需要使用开关来提取枚举的关联值。

switch decoded {
case .Success(let header, let payload, let signature, let signatureInput):
    // do something with the values
case .Failure(let invalidToken):
    // handle the failure
}
