Convert CURL to Swift for using in Alamofire

Question

My CURL is

curl --header "secret: mytoken" --data "a=addPost&session=mySession&postBody=test" https://example.com/testing/

I want to use it with Alamofire. How to convert it to Swift code?

Update.

My code is:

@IBAction func postTapped(_ sender: UIButton) {
    guard let url = URL(string: "https://example.com/testing/") else { return }

    let headers = [
        "secret": "mytoken"
    ]

    let parameters = [
        "a": "addPost",
        "session": "mySession",
        "postBody": "test"
    ]

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

But I am getting this error:

FAILURE: responseSerializationFailed(reason: Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(error: Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.}))

Update 2.

When I use this CURL in mac os terminal I got the correct JSON:

{"result":100,"data":{"id":"mydata"}

But in swift code I got error.

The error says that the returned data is not JSON. Print the received data as string to see what you get. You might tell the server that the data type is JSON. — vadian, May 03 '19 at 11:20
Does the HTML you obtained contain an error message? You can get HTML string like this. https://stackoverflow.com/questions/38421011/alamofire-swift-get-html-source — shtnkgm, May 03 '19 at 11:28

let parameters: Parameters = [
    "a": "addPost",
    "session": "mySession",
    "postBody": "test"
]

let headers: HTTPHeaders = [
    "secret": "mytoken"
]

Alamofire.request("https://example.com/testing/", parameters: parameters, headers: headers).responseJSON { response in
    // do something
}

Solution - use URLEncoding(destination: .httpBody)(thx Larme):

Alamofire.request(url, method: .post, parameters: parameters, encoding: URLEncoding(destination: .httpBody), headers: headers).responseJSON { (response) in
    print(response)
}
