Error Domain=NSCocoaErrorDomain Code=3840 "Unescaped control character
around character 981." UserInfo={NSDebugDescription=Unescaped control
character around character 981.}

我在响应请求时收到上述错误。

下面是代码行:

Alamofire.request(.POST, urlStr, parameters: parameter, encoding: .JSON, headers: nil).validate().responseJSON {
    response in switch response.result {

        case .Success(let JSON):
            completionHandler(JSON as! NSDictionary)

        case.Failure(let Error):

            print(Error)
    }
}

它在 Postman 中给出一个 JSON 响应。

我在 Postman 中得到的响应:

最佳答案

据您所知，存在与“\n”相关的问题。

所以我建议您可以添加适合您的“”，如下所示:

"\n"=> "\\n"

因为这是一个叫做退格符的特殊字符。
