Question

当我尝试向Web API发送JSON字符串'parametersString'时，parameterEncoderFailed出现错误消息，有人可以帮助我解决问题

失败（Alamofire.AFError.parameterEncoderFailed（原因： Alamofire.AFError.ParameterEncoderFailureReason.encoderFailed（错误： Alamofire.URLEncodedFormEncoder.Error.invalidRootObject（“ string（\” {\ n \\“ authenticate \\”： {\ n \\“ userName \\”：\\“ fan.doe \\”，\ n \\“ password \\”： \\“ 12345 \\”，\ n \“到期\\”：\\“ 2019-05-03 18:00:00 \\“ \ n} \ n} \”）“）））））））

 static func Login(email:String, password:String, completion: @escaping (_ success: Bool, _ response: DataResponse<Data?>?) -> ()) {
        let urlString: 

        let parametersString = """
        {
        "authenticate": {
        "userName": "\(email)",
        "password": "\(password)",
        "expiry": "2019-05-03 18:00:00"
        }
        }
        """
         var response:DataResponse<Data?>?

        print(urlString)
        AF.request(urlString, method: .post, parameters: parametersString, encoding:  String.Encoding.utf8.rawValue,  headers: headers )
            .response { resp in
                response = resp
                print(response)
                if(response?.response?.statusCode == 200){
                    completion(true, response)

                }
                else {
                    completion(false, nil)
                }
        }

    }
}

您可能需要发送字典[String:Any]

let parametersDic:[String:Any] = [
    "authenticate": [
    "userName": "\(email)",
    "password": "\(password)",
    "expiry": "2019-05-03 18:00:00"
]]

参数Encoder失败，因为invalidRootObject？
