带有Alamofire 4数据的POST请求

怎么可能用Alamofire 4发送POST请求与HTTP正文中的数据？ 我使用自定义编码在迅速2.3它工作良好。 我转换我的代码swift 3，我试图参数编码，但不工作。 此代码：

public struct MyCustomEncoding : ParameterEncoding { private let data: Data init(data: Data) { self.data = data } public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest { var urlRequest = try urlRequest.asURLRequest() do { urlRequest.httpBody = data urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type") } catch { throw AFError.parameterEncodingFailed(reason: .jsonEncodingFailed(error: error)) } return urlRequest } 

和Alamofire要求：

 let enco : ParameterEncoding = MyCustomEncoding(data: ajsonData) Alamofire.request(urlString, method: .post , parameters: [:], encoding: enco , headers: headers).validate() .responseJSON { response in switch response.result { case .success: print(response) break case .failure(let error): print(error) } }

你需要在swift 3中发送如下的请求

 let urlString = "https://httpbin.org/get" Alamofire.request(urlString, method: .post, parameters: ["foo": "bar"],encoding: JSONEncoding.default, headers: nil).responseJSON { response in switch response.result { case .success: print(response) break case .failure(let error): print(error) } }
