Alamofire JSONをPOST

パラメータにJSONを指定する例

curlだとこう

curl -X POST \
  http://api.exsample.com/api/v1/login \
  -H 'Content-Type: application/json' \
  -H 'cache-control: no-cache' \
  -d '{
    "auth": {
        "phone_number": "090xxxxxxxx",
        "password": "password"
    }
}'

Alamofireの場合

let parameters = [
    "auth": [
             "phone_number": "090xxxxxxxx",
             "password": "password"
            ]
    ]

Alamofire.request("http://api.exsample.com/api/v1/login",
  method: .post, 
  parameters: parameters, 
  encoding: JSONEncoding.default, headers: nil)
.responseJSON { response in
    if let result = response.result.value as? [String: Any] {
       print(result)
    }
}
