Pass parameter with json field when invoking POST in Alamofire - ios

Question

I have encountered an issue in swift 3:
I have an API which I need to access for data in my app, but the parameter that it demands is in the following format:
"jsonRequest" = {
"header" : "GetLocationListReq",
"accessKey" : "1234567890abcdefghij"
}//this is in json format.
I tried to pass this parameter as dictionary to call the API, but at that point I obtained this message error:
Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed
Any one knows how I can solve the problem?

Answer 1

I think you want to pass these things in header of the request.
for that you need to do like this
let headers = ["header": "GetLocationListReq",
"accessKey": "1234567890abcdefghij"]
Alamofire.request(url, method: .post, parameters: nil, encoding: JSONEncoding.default, headers: headers).responseJSON{
r in
//do what you want here
}
hope this will work.

Answer 2

try to post this code
let par:[String:Any] = ["jsonRequest":[
"header" : "GetLocationListReq",
"accessKey" : "1234567890abcdefghij"
]]
pass it like that in Alamofire
Alamofire.request(url, method: .post, parameters: par, encoding: JSONEncoding.default, headers: nil).responseJSON{
r in
//do what you want here
}
