swift - URL 请求的编码参数

Question

我创建了一个路由器来生成 URL 请求。

enum Router: URLRequestConvertible {
    static let baseURLString = "SERVERIP"

    case GetAEDInRange(String) 
    // match URLRequest routes to Alamofire methods
    var URLRequest: NSMutableURLRequest {
        var method: Alamofire.Method {
            switch self {

            case .GetAEDInRange:
                return .GET
            }
        }

        // The output contains the path and parameters like ("aeds", newAED)
        let result: (path: String, parameters: [String: AnyObject]?) = {
            switch self {

            case .GetAEDInRange(let parameters):
                return ("aeds", parameters)
        }()

        // Generate URL Request
        let URL = NSURL(string: Router.baseURLString)!

        // Append the path components from the result
        print(result.path)
        let URLRequest = NSURLRequest(URL: URL.URLByAppendingPathComponent(result.path))

        // Create URLRequest inclunding the encoded parameters
        let encoding = Alamofire.ParameterEncoding.JSON
        let (encodedRequest, _) = encoding.encode(URLRequest, parameters: result.parameters)
        encodedRequest.HTTPMethod = method.rawValue
        return encodedRequest
    }
}

我期望的输出是:http://BASEURL/v1/aed?latitude=100&longitude=100

当我使用 Alamofire 发出带有附加参数的 GET 请求时，它工作正常:

    Alamofire.request(.GET, "http://SERVER/v1/aeds", parameters: parameters).responseJSON { (response) -> Void in
        print(response.result.value)
    }

当我改用我的路由器时，输出没有按预期生成:

    Alamofire.request(Router.GetAEDInRange(parameters)).responseJSON { (response) -> Void in
        print(response.result.value)
    }

当我打印 URL 字符串时，我得到:`http://SERVER/v1/aeds/ `` 我需要如何更换路由器？我以某种方式与参数组件作斗争。

改变这一行

let encoding = Alamofire.ParameterEncoding.JSON

为此:

let encoding = Alamofire.ParameterEncoding.URLEncodedInURL
