【问题描述】：

我目前正在使用 cocoapods 1.1.0.rc.2。我已经安装了 Alamofire 吊舱。对于 1.1.0.rc.2 版本，它应该适用于 swift 3.0。 但是我正在尝试声明以下枚举

enum Router: URLRequestConvertible 
        static let baseURLString = "https://api.instagram.com"
        static let clientID = "myID"
        static let redirectURI = "http://www.example.com/"
        static let clientSecret = "mySecret"

        case PopularPhotos(String, String)
        case requestOauthCode

        static func requestAccessTokenURLStringAndParms(code: String) -> (URLString: String, Params: [String: AnyObject]) 
            let params = ["client_id": Router.clientID, "client_secret": Router.clientSecret, "grant_type": "authorization_code", "redirect_uri": Router.redirectURI, "code": code]
            let pathString = "/oauth/access_token"
            let urlString = Instagram.Router.baseURLString + pathString
            return (urlString, params as [String : AnyObject])
        

        // MARK: URLRequestConvertible

        var URLRequest: NSMutableURLRequest 
            let result: (path: String, parameters: [String: AnyObject]?) = 
                switch self 
                case .PopularPhotos (let userID, let accessToken):
                    let params = ["access_token": accessToken]
                    let pathString = "/v1/users/" + userID + "/media/recent"
                    return (pathString, params as [String : AnyObject]?)

                case .requestOauthCode:
                    let pathString = "/oauth/authorize/?client_id=" + Router.clientID + "&redirect_uri=" + Router.redirectURI + "&response_type=code"
                    return (pathString, nil)
                
            ()

            let baseURL = NSURL(string: Router.baseURLString)!
            let URLRequest = NSURLRequest(url: NSURL(string: result.path ,relativeTo:baseURL as URL)! as URL)
            let encoding = Alamofire.ParameterEncoding.encode(baseURL as! ParameterEncoding)
            //let encoding = Alamofire.ParameterEncoding.URL
            return encoding.encode(URLRequest, parameters: result.parameters).0
        
    

但是在构建这个时我得到了以下错误。

Type 'Router' does not conform to protocol 'URLRequestConvertible'

有人知道我在这里缺少什么吗？

【问题讨论】：

我遇到了同样的问题。你有没有找到任何解决方案。谢谢

@ravisendhav 不，不幸的是我还没有找到任何东西

您可以在我下面的帖子中查看解决方案。

【参考方案1】：

enum Router: URLRequestConvertible 

    static let baseURLString = "www.google.com"


    case getToken([String: AnyObject])

    var method: HTTPMethod 

        switch self 
        case .getToken:
            return .post
        default:
            break

        
    

    var path: String 
        switch self 
        case .getToken:
            return "token"
        default:
            break
        
    


     func asURLRequest() throws -> URLRequest 

        let url = Foundation.URL(string: baseURLString)!

        var urlRequest = URLRequest(url: url.appendingPathComponent(path))
        urlRequest.httpMethod = method.rawValue


        urlRequest.setValue("application/json", forHTTPHeaderField: "Content")
        urlRequest.setValue("keep-alive", forHTTPHeaderField: "Connection")

        switch self 
        case .getToken(let parameters):
            urlRequest = try URLEncoding.default.encode(urlRequest, with: parameters)
        default:
            break
        
        return urlRequest
