Alamofire 4 Error Request 'Extra Argument in Call'

Extra argument in call Alamofire Swift

you have create simple method.you need to create completion block parameter

try this code

  class func checkServerForLogin(_ url:String,email: String, password: String,success:@escaping (JSON) -> Void, failure:@escaping (Error) -> Void) {

            let parameters = [
                "email": email,
                "password": password
                ] as [String : Any]

            Alamofire.request(url, method: .post, parameters: parameters).responseString { (response) in

                if response.result.isSuccess {
                    let resJson = JSON(response.result.value!)
                    success(resJson)
                }
                if response.result.isFailure {
                    let error : Error = response.result.error!
                    failure(error)
                }
            }
        }

AuthService.checkServerForLogin(URL_CHECK_LOGIN, email: email_input, password: password_input, success: { (responseObject) in
            print(responseObject)
        }) { (error) in
            print(error.localizedDescription)
        }

Alamofire 4 error request 'extra argument in call'

The encoding argument of request(...) expects static properties, not enum cases.

We can take a look at the signature of the static request(...) method of Alamofire (Alamofire/Source/Alamofire.swift)

public func request(
    _ url: URLConvertible,
    method: HTTPMethod = .get,
    parameters: Parameters? = nil,
    encoding: ParameterEncoding = URLEncoding.default,
    headers: HTTPHeaders? = nil)
    -> DataRequest
{ /* ... */ }

The first argument is one which conforms to the protocol URLConvertible, to which String is valid; all good so far.

The type of the 2nd argument is simply an enum to which .post is a valid case, OK.

The third argument should be of type Parameters, which is a typealias for [String: Any]

/// A dictionary of parameters to apply to a `URLRequest`.
public typealias Parameters = [String: Any]

The argument you supply, pulseNewVote, is of type Dictionary<String, Array<Dictionary<String, Any>>>, but should still be able to be consumed by the expected argument type (Dictionary<String, Any>). So this should still be OK, even if you might want to consider helping Swift out by explicitly type annotating the type of pulseNewVote to [String: Any]:

var pulseNewVote: [String: Any] = ...

The fourth argument, the encoding, however, is not an enum, but a protocol ParameterEncoding to which a few struct types conform. These type have static members (returning an instance of self) which may look like enum cases when explicitly type, but which must include the explicit typing

public struct JSONEncoding: ParameterEncoding {

    // MARK: Properties
    /// Returns a `JSONEncoding` instance with default writing options.
    public static var `default`: JSONEncoding { return JSONEncoding() }
    // ...
}

Hence, you need to replace the value supplied to your fourth argument, .json, with e.g. JSONEncoding.default. With this fix, your call to request should look like:

Alamofire.request(pulseVoteEndpoint, method: .post, parameters: pulseNewVote, encoding: JSONEncoding.default)

The error you're given (additional parameters) come from, however, the completion handler to the reponse call. The completion handler supplied to a call to response is one which takes a single DefaultDataResponse as argument (not 4 different arguments as in your attempt). An instance of the DefaultDataResponse type have public members request, response, data and error, which you may access via the single response parameter (of type DefaultDataResponse) in the completion handler. Adapting the completion handler in your response call to this fact (using the example from the Alamofire documentation, we may construct the final request and response chained call:

Alamofire.request(pulseVoteEndpoint, method: .post, parameters: pulseNewVote, encoding: JSONEncoding.default)
    .response { response in
    // note that these are all optionals, so
    // you might want to unwrap them first
    print(response.request)
    print(response.response)
    print(response.error)
}

Extra argument 'method' in call Alamofire swift 4

There is something wrong with your AppDelegate.NOTIFICATION_URL variable in the AppDelegate.

Because when I removed the key, the piece of code started working.. Hope this will help you find the solution.

    func setUpPushNotification(fromDevice: String) {

    let title = ""
    let url = "something"
    let body = "You got a friend request"
    let toDeviceID = fromDevice
    var headers:HTTPHeaders = HTTPHeaders()
    let Method = Alamofire.HTTPMethod.post

    headers = ["Content-Type":"application/json","Authorization":"key=1236"]

    let notification = ["to":"\(toDeviceID)","notification":["body":body,"title":title,"badge":1,"sound":"default"]] as [String : Any]

    Alamofire.request(url as URLConvertible , method: Method, parameters: notification, encoding: JSONEncoding.default, headers: headers)
}

Extra argument in .request call -- Alamofire + Swift

I figured out the issue, no thanks to any documentation or GitHub threads.

The logic in the above code snippet (from the question) referenced a constant called headers, which was declared outside of getPlaceData(url:parameters:). This is because in order to access the Yelp Fusion API you need to include an extra field in the HTTP header you send to include the private API key using the format mentioned here.

I moved the headers data structure inside of getPlaceData(url:parameters:) and it fixed the issue, so my resulting function is as follows:

static func getPlaceData(url: String, parameters: [String: String]) {
  let headers: HTTPHeaders = [
    "Authorization": "Bearer /*PRIVATE KEY*/"
  ]

  Alamofire.request(url, method: .get, parameters: parameters, encoding: 
  JSONEncoding.default, headers: headers).responseJSON { (response) in
    if response.result.isSuccess {
      let json: JSON = JSON(response.result.value!)
      print(json)
    } else {
      print("error")
    }
  }
}

Not sure why this fixed the issue, but the code works now.

Swift Alamofire Request Error - Extra Argument in call

Try change your request to something like this:

Alamofire.request(searchURL, method: .get, parameters: ["query": term, "region": 2, "lang": "en"], encoding: JSONEncoding.default, headers: nil)

Alamofire post request error Extra argument 'method' in call

your attributes probably aren't valid (if the types don't match Xcode will tell you the error with the closest matching function)

try changing JSONEncoding to JSONEncoding.default and that your body matches [String:Any]

Alamofire.request(String, method: HTTPMethod.post, parameters: [String:Any], encoding: JSONEncoding.default, headers: header)

something along these lines (I don't know about the header attribute I usually have this at nil)

Alamofire v4 extra argument method in call error

I had this issue upgrading to Alamofire 4 and solved it by moving the headers argument and making it the last argument in the call. Also encoding: .JSON should be encoding: JSONEncoding.default.

Call should look like this:

Alamofire.request(url: myUrl, method: .put, parameters: myParams,
     encoding: JSONEncoding.default, headers: myHeaders)
