Swift 5 & Alamofire 5 : GET method ERROR:

error: urlRequestValidationFailed(reason: Alamofire.AFError.URLRequestValidationFailureReason.bodyDataInGETRequest(2 bytes))

解決方法

使用 URLEncoding.default 代替 JSONEncoding.default

AF.request(path, 
          method: .get, 
      parameters: params, 
        encoding: URLEncoding.default, 
         headers: nil)
  .response { (responseData) in

}
