Post Request with Data in Body with Alamofire 4

POST request with data in body with Alamofire 4

You need to send request like below in swift 3

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:

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
        }
    }

Alamofire post request:

There are many ways to implement the requests using Alamofire, this is a simple example:

First, do you have to create the parameters, URL from your API and headers:

let parameters = [
    "username": "foo",
    "password": "123456"
]

let url = "https://httpbin.org/post"

static private var headers: HTTPHeaders {
        get {
            return [
               "Authorization" : "Bearer \(Session.current.bearerToken ?? "")"
            ]
        }
    }

So you call the function from Alamofire and pass your data:

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

:)

Alamofire set request body with Data

Alamfire accepts [String:Any]

 do {
     let params  = try JSONSerialization.jsonObject(with: data, options: []) as! [String:Any]
     Alamofire.request(url, method: .post, parameters:params, encoding: JSONEncoding.default, headers: headers)
    request.validate().responseJSON {
     ...
    }
  } 
  catch {
      print(error)
  }

Swift 4.2

Alamofire.request(url, method: .post, parameters: [:], encoding: "test", headers: [:])  

extension String: ParameterEncoding {

    public func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var request = try urlRequest.asURLRequest()
        request.httpBody = data(using: .utf8, allowLossyConversion: false)
        return request
    }

}

How to send a POST request with BODY in swift

You're close. The parameters dictionary formatting doesn't look correct. You should try the following:

let parameters: [String: AnyObject] = [
    "IdQuiz" : 102,
    "IdUser" : "iosclient",
    "User" : "iosclient",
    "List": [
        [
            "IdQuestion" : 5,
            "IdProposition": 2,
            "Time" : 32
        ],
        [
            "IdQuestion" : 4,
            "IdProposition": 3,
            "Time" : 9
        ]
    ]
]

Alamofire.request(.POST, "http://myserver.com", parameters: parameters, encoding: .JSON)
    .responseJSON { request, response, JSON, error in
        print(response)
        print(JSON)
        print(error)
    }

Hopefully that fixed your issue. If it doesn't, please reply and I'll adjust my answer accordingly.
