ios - Alamofire 4 Swift 3 参数编码自定义

Question

我将我的项目更新为 Swift 3 和 Alamofire 4。我使用的是自定义编码，但它已更改为其他编码方法。我找不到替代品/等效于此:

alamoFire.request(urlString, method: HTTPMethod.post, parameters: [:], encoding: .Custom({
        (convertible, params) in

        let mutableRequest = convertible.URLRequest.copy() as! NSMutableURLRequest
        let data = (body as NSString).data(using: String.Encoding.utf8)
        mutableRequest.httpBody = data
        return (mutableRequest, nil)

    }), headers: headers()).responseJSON { (responseObject) -> Void in

        switch responseObject.result {
        case .success(let JSON):
            success(responseObject: JSON)

        case .failure(let error):
            failure(error: responseObject)
        }
    }

我还尝试通过制作 URLRequest 对象和简单的请求，它也给我错误

var request = URLRequest(url: URL(string: urlString)!)
    let data = (body as NSString).data(using: String.Encoding.utf8.rawValue)
    request.httpBody = data
    request.httpMethod = "POST"
    request.allHTTPHeaderFields = headers()

    alamoFire.request(request).responseJSON { (responseObject) -> Void in

        switch responseObject.result {
        case .success(let JSON):
            success(JSON)

        case .failure(let error):
            failure(responseObject, error)
        }
    }

给我指明方向，如何将 httpbody 与 Alamofire 4 连接

试试这个方法？

Alamofire.request(url, method: HTTPMethod.post, parameters: parameters, encoding: URLEncoding.httpBody, headers: nil).responseObject(completionHandler: { (response : DataResponse<T>)  in

})
