带有Alamofire 4的数据的POST请求

Question

如何使用Alamofire 4在HTTP正文中发送带有数据的POST请求？我在swift 2.3上使用自定义编码它运行良好.我转换了我的代码swift 3,我尝试使用paramater编码,但没有工作.这段代码:

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)
                    }
    }

Answer 1

您需要在swift 3中发送如下所示的请求

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)
                }
}

Alamofire 使用 post 方法 import UIKit import Alamofire

class ViewController: UIViewController {
    let parameters = [
        "username": "foo",
        "password": "123456"
    ]
    let url = "https://httpbin.org/post"

override func viewDidLoad() {
        super.viewDidLoad()
Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: [:]).responseJSON {
            response in
            switch (response.result) {
            case .success:
                print(response)
                break
            case .failure:
                print(Error.self)
            }
        }
}
