Alamofire 的身份验证一直失败

Question

我最近将我的项目迁移到 Swift 2.0，但出现了很多错误。我修复了大部分，但是这个一直出错。

我正在使用 Alamofire 调用 Bing 搜索 API，如下所示，我收到一条错误消息，提示 "Error Domain=NSCocoaErrorDomain Code=3840 " 字符 0 周围的值无效。” UserInfo={NSDebugDescription=字符周围的值无效0.}"

我理解这意味着身份验证失败。有人可以告诉我如何解决这个问题吗？

let percentedKeyword = searchKey.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())
Let ulrStr: String = "https://api.datamarket.azure.com/Bing/Search/v1/News" + "? Query=" + percentedKeyword! + "&$top=10&$format=JSON"
let credentials = ":\(bingApiKey)"
let plainText = credentials.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
let base64 = plainText!.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))

let headers = ["Authorization": "Basic \(base64)"]

Alamofire.request(.GET, urlStr, headers: headers)
    .responseJSON { request, response, data in
        switch data {
        case Result.Success(let receivedValue):
            self.bingJson = JSON(receivedValue)
        case Result.Failure(_, let error as NSError):
            print(error)
        default:
            print("do nothing")
        }
}

Xcode 版本 7.0 Alamofire 版本 2.0.2

[更新]

我尝试了 urlStr("https://api.datamarket.azure.com/Bing/Search/News?Query=%E4%B8%AD%E5%9B%BD&$top=10&$format=JSON") 网络浏览器。它要求我输入用户名和密码，所以我输入 apiKey 作为密码，并按照 Microsoft doc

的说明将用户名留空

我明白了 error:Parameter: 查询不是字符串类型

根据Whosebug，这是因为关键字没有百分比，但我在关键字字符串中添加了百分比...

原来我搜索关键词需要单引号。

let percentedKeyword = searchKey.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())
        let urlStr: String = "https://api.datamarket.azure.com/Bing/Search/News" + "?Query=" + "'" + percentedKeyword! + "'" + "&$top=10&$format=JSON"
        let credentials = ":\(bingApiKey)"
        let plainText = credentials.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
        let base64 = plainText!.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))

        let headers = ["Authorization": "Basic \(base64)"]

        Alamofire.request(.GET, urlStr, headers: headers)
            .responseJSON { request, response, data in
                switch data {
                case Result.Success(let receivedValue):
                    self.bingJson = JSON(receivedValue)
                case Result.Failure(_, let error as NSError):
                    print(error)
                default:
                    print("do nothing")
                }
        }
    }
