POST request with data in body with Alamofire 4

提问by Cagatay

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 :

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 中使用了自定义编码，效果很好。我转换了我的代码 swift 3 并尝试参数编码但没有工作。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
}

and Alamofire request :

和 Alamofire 请求：

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)
                    }
    }

You need to send request like below in swift 3

您需要在 swift 3 中发送如下请求

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)
                }
}

Swift 5 with Alamofire 5:

Swift 5 与 Alamofire 5：

AF.request(URL.init(string: url)!, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers).responseJSON { (response) in
        print(response.result)

        switch response.result {

        case .success(_):
            if let json = response.value
            {
                successHandler((json as! [String:AnyObject]))
            }
            break
        case .failure(let error):
            failureHandler([error as Error])
            break
        }
    }

This will work better in Swift 4.

这在 Swift 4 中效果更好。

let url = "yourlink.php". // This will be your link
let parameters: Parameters = ["User_type": type, "User_name": name, "User_email": email, "User_contact": contact, "User_password": password, "from_referral": referral]      //This will be your parameter

Alamofire.request(url, method: .post, parameters: parameters).responseJSON { response in
    print(response)
}

Alamofire using post method import UIKit import Alamofire

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)
            }
        }
}

Alamofire for GET and POST method using Alamofire

使用 Alamofire 实现 GET 和 POST 方法的 Alamofire

1.Create a file named "GlobalMethod" for multiple use

1.创建一个名为“GlobalMethod”的文件以供多次使用

import Alamofire
class GlobalMethod: NSObject {

    static let objGlobalMethod = GlobalMethod()

    func ServiceMethod(url:String, method:String, controller:UIViewController, parameters:Parameters, completion: @escaping (_ result: DataResponse<Any>) -> Void) {

            var headers = Alamofire.SessionManager.defaultHTTPHeaders
            headers["HeaderKey"] = "HeaderKey"
            if method == "POST" {
                methodType = .post
                param = parameters
            }
            else {
                methodType = .get
            }
            Alamofire.request(url, method: methodType, parameters: param, encoding: JSONEncoding.default, headers:headers
                ).responseJSON
                { response in

                    completion(response)
            }
        }
}

1. In the View Controller call "ServiceMethod" created in GlobalMethod by sending values to call API Service

   let urlPath = "URL STRING"
   let methodType = "GET" or "POST" //as you want
   let params:[String:String] = ["Key":"Value"]
   
   GlobalMethod.objGlobalMethod.ServiceMethod(url:urlPath, method:methodType, controller:self, parameters:params)
           {
               response in
   
               if response.result.value == nil {
                   print("No response")
                   return
               }
               else {
                 let responseData = response.result.value as! NSDictionary
                 print(responseData)
               }
           }
   

2. 在 View Controller 中，通过发送值调用 API 服务来调用 GlobalMethod 中创建的“ServiceMethod”

   let urlPath = "URL STRING"
   let methodType = "GET" or "POST" //as you want
   let params:[String:String] = ["Key":"Value"]
   
   GlobalMethod.objGlobalMethod.ServiceMethod(url:urlPath, method:methodType, controller:self, parameters:params)
           {
               response in
   
               if response.result.value == nil {
                   print("No response")
                   return
               }
               else {
                 let responseData = response.result.value as! NSDictionary
                 print(responseData)
               }
           }
