如何使用Alamofire 4在HTTP主体中发送具有数据的POST请求？我在swift 2.3中使用了自定义编码，这是很好的。我转换了我的代码swift 3，我试图参数编码，但不工作。这个代码：

how is it possible to send a POST request with a data in the HTTP body with Alamofire 4? I used custom encoding at swift 2.3 it was working good. I converted my code swift 3 and I tried to paramater encoding but not working. This code :

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请求：

and Alamofire request :

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) } }

推荐答案

您需要在swift 3中发送如下所示的请求

You need to send request like below in swift 3

let urlString = "httpbin/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) } }
