Alamofire post request with body - ios

Question

I am trying to send POST HTTP request with body using Alamofire and would appreciate any help.
My body:
{"data":{"gym":{"country":"USA","city":"San Diego","id":1}}}
Should I do something like this?
let parameters: [String: Any] = [ "data": [
"gym": [
"country":"USA",
"city":"San Diego",
"id":1
]]]
Alamofire.request(URL, method: .post, parameters: parameters, headers: headers())
.responseJSON { response in
print(response)
}

Answer 1

If you wish to send the parameters in json format use encoding as JSONEncoding. So add parameter for encoding in request as follows:
Alamofire.request(URL, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers())
.responseJSON { response in
print(response)
}
Hope it helps...

Try this method to convert your json string to dictionary
func convertToDictionary(text: String) -> [String: Any]? {
if let data = text.data(using: .utf8) {
do {
return try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
} catch {
print(error.localizedDescription)
}
}
return nil
}
let str = "{\"data\":{\"gym\":{\"country\":\"USA\",\"city\":\"San Diego\",\"id\":1}}}"
let dict = convertToDictionary(text: str)
and send dictionary as a param in your request.
Alamofire.request(URL, method: .post, parameters: dict, headers: headers())
.responseJSON { response in
print(response)
}

What I think is that you should try and prepare your dictionary in the this format:
var gym = [String:Any]()
gym["country"] = "USA"
gym["city"] = "San"
var data = [[String:Any]]()
data.append(gym)
var metaData = [String:Any]()
metaData["data"] = data

Answer 4

Your parameters is wrong...
let parameters: [String: Any] = { "data":
{
"gym": {
"country":"USA",
"city":"San Diego",
"id":1
}
}
}
Alamofire.request(<YOUR-URL>,
method: .post,
parameters: parameters,
encoding: URLEncoding(destination: .queryString),
headers: <YOUR-HEADER>
).validate().responseString { response in
switch response.result {
case .success:
debugPrint("Good to go.")
debugPrint(response)
case .failure:
let errMsg = String(data: response.data!, encoding: String.Encoding.utf8)!
debugPrint(errMsg)
debugPrint(response)
}
}
Hope this help. BTW, in Alamofire 5, debugPrint(response) can print out response.data directly.

You can use the httpBody property of URLRequest along with Alamofire Session request:
var req = try? URLRequest(url: url, method: method, headers: headers)
req?.httpBody = someJson
Alamofire.Session(configuration: .default).request(req!).validate().response { response in
// Handle the response
}
