Post method request Alamofire - ios

Question

I'm using Swift 3 and Alamofire 4.0.
I want to create similar Alamofire POST request as Postman request shown in screenshot:
I've tried with these lines of code:
var parameters: [String: Any] = [
"client_id" : "xxxxxx",
"client_secret" : "xxxxx",
"device_token" : "xxxx",
"fullname" : "xxxxx",
"gender": "xxx"
]
Alamofire.request(url, method: .post, parameters: parameters).responseJSON { response in
print(response)
}
But I got this error:
How to implement POST request with Body as form-data using Alamofire in Swift 3?

Answer 1

Swift 3.0 - Alamofire - Working code for multipart form data upload *
// Parameters
let params: [String : String] =
["UserId" : "\(userID)",
"FirstName" : firstNameTF.text!,
"LastName" : lastNameTF.text!,
"Email" : emailTF.text!
]
// And upload
Alamofire.upload(
multipartFormData: { multipartFormData in
for (key, value) in params
{
multipartFormData.append((value.data(using: .utf8))!, withName: key)
}
},
to: url,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
debugPrint(response)
}
upload.uploadProgress(queue: DispatchQueue(label: "uploadQueue"), closure: { (progress) in
})
case .failure(let encodingError):
print(encodingError)
}
}
)
Let me know if you still have issues with it.

after too much try I have succeded so try this
override func viewDidLoad() {
super.viewDidLoad()
let parameters: Parameters = ["client_id": "1","user_token":"xxxxxxxx"]
// Do any additional setup after loading the view, typically from a nib.
let url = "http://xxxxxxxxxxx/index.php/Web_api/get_client_profile"
//let timeParameter = self.getLastTimeStamp()
self.request = Alamofire.request(url, method: .post, parameters:parameters)
if let request = request as? DataRequest {
request.responseString { response in
//PKHUD.sharedHUD.hide()
do{
let dictionary = try JSONSerialization.jsonObject(with: response.data!, options: JSONSerialization.ReadingOptions.allowFragments) as! NSDictionary
print(dictionary)
}catch{
}
}
}
}
var request: Alamofire.Request? {
didSet {
//oldValue?.cancel()
}
}

You can post a request using Alamofire.
let url = ""
let headers = [ "Content-Type" : "application/json"]
let para : Parameters = [ "data" : JSONObject]
Alamofire.request(url, method: .post, parameters: para, encoding: JSONEncoding.default, headers : headers)
.responseJSON { response in
print(response)
print(response.result)
}

Nothing to worry about.
Alamofire request method not changed so much(For Swift 3.0) if in case you know how to do that in Swift 2.0/2.2. If you understand the old method then you can easily understand this one also. Now lets take a closer look on the following boilerplate -
Alamofire.request(apiToHit, method: .post, parameters: parametersObject, encoding: JSONEncoding.default, headers: headerForApi).responseJSON { response in switch response.result{
case .success(_):
if let receivedData: Any = response.result.value{
if let statusCode: Int = response.response?.statusCode {
//Got the status code and data. Do your data pursing task from here.
}
}else{
//Response data is not valid, So do some other calculations here
}
case .failure(_):
//Api request process failed. Check for errors here.
}
Now here in my case -
apiToHit //Your api url string
.post //Method of the request. You can change this method as per you need like .post, .get, .put, .delete etc.
parametersObject // Parameters needed for this particular api. Same in case you are sending the "body" on postman etc. Remember this parameters should be in form of [String: Any]. If you don't need this then you can just pass nil.
JSONEncoding.default //This the encoding process. In my case I am setting this as .default which is expected here. You can change this to .prettyPrinted also if you need.
headerForApi //This is the header which you want to send while you are requesting the api. In my case it is in [String: String] format. If you don't need this then you can just pass nil.
.responseJSON //Expecting the response as in JSON format. You can also change this as you need.
Now, in my request I am using Switch inside the request closure to check the result like response in switch response.result{.
Inside case .success(_): case I am also checking for result data and http status code as well like this
if let receivedData: Any = response.result.value{
if let statusCode: Int = response.response?.statusCode {
}
}
Hope this helped. Thanks.
