Swift Alamofire Getting Token from Refresh Token Request Error

问题:

I'm pretty new to using Alamofire, and I am banging my head against the wall with this request. I'm using GIDSignIn, and successfully get a token and refresh token for the user, with the scope ["https://www.googleapis.com/auth/youtube.readonly"].

I'm trying to complete this request, as shown as an example on the site. The site says to ignore using client_secret for iOS, which I do.

POST /oauth2/v4/token HTTP/1.1 Host: www.googleapis.com Content-Type: application/x-www-form-urlencoded  client_id=<your_client_id>& client_secret=<your_client_secret>& refresh_token=<refresh_token>& grant_type=refresh_token 

Below is how I've implemented it with Alamofire. My client_id is the value from the CLIENT_ID key in the GoogleService-Info.Plist, a string ending in .apps.googleusercontent.com. The refresh_token also seems to have the right format from other examples I've seen online.

let endpoint = "https://www.googleapis.com/oauth2/v4/token" let parameters = [     "client_id" : client_id,      "refresh_token" : refresh_token,      "grant_type" : "refresh_token" ]  Alamofire.request(endpoint, method: .post,                    parameters: parameters,                    encoding: JSONEncoding.default)          .responseJSON { (data) in             print("data: \(data)")             let json = JSON(data.result)         } 

The data response is

data: SUCCESS: {     error = "unsupported_grant_type";     "error_description" = "Invalid grant_type: "; } 

Not terribly successful. Do I need to configure my request differently, or get appropriate access / permission to get the token? Thank you so much!

@BikeshThakur helped me figure it out! The URLEncoding.httpBody did the trick! I don't need any headers either.

Alamofire.request(endpoint, method: .post,                    parameters: parameters,                    encoding: URLEncoding.httpBody)

i have tired in my code like this way , you also need to check sometime encoding type URLEncoding.httpBody hope it may help

  let headers = [         "Content-Type": "application/x-www-form-urlencoded"     ]      Alamofire.request("https://accounts.google.com/o/oauth2/revoke?token={\(token)}", method: .post, parameters: parameters, encoding:  URLEncoding.httpBody, headers: headers).responseJSON { (response:DataResponse<Any>) in
