如何根据API类型使用BODY发送POST或GET请求

我创建了一个网络管理器类，允许通过控制器共享响应实例。根据控制器类型，我调用定义为方法GET的API，但是在某些情况下，它需要POST方法来发送服务器并等待以授予令牌身份验证开始的响应。

在网络管理器类中，我创建了调用HttpRequest的函数

   func callingHttpRequest(params:Dictionary<String,Any>, apiname:String,cuurentView:UIViewController,taskCallback: @escaping (Int,
        AnyObject?) -> Void)  {

        let urlString  = HOST_NAME + apiname

        print("url",urlString)
        print("params", params)
        Alamofire.request(urlString,method: .get,parameters:params).validate().responseJSON { response in
            switch response.result {
            case .success(let resultData):
                taskCallback(1,resultData as AnyObject)
                break
            case .failure(let error):

                 let returnData = String(data: response.data! , encoding: .utf8)
                 print("returnData" ,returnData)
                print("request URL", response.request)

                if !Connectivity.isConnectedToInternet(){
                    NetworkManager.sharedInstance.dismissLoader()
                    cuurentView.view.isUserInteractionEnabled = true
                    let AC = UIAlertController(title: "Warning", message: error.localizedDescription, preferredStyle: .alert)
                    let okBtn = UIAlertAction(title: "Retry", style: .default, handler: {(_ action: UIAlertAction) -> Void in
                        taskCallback(2, "" as AnyObject)
                    })
                    let noBtn = UIAlertAction(title: "Cancel", style: .destructive, handler: {(_ action: UIAlertAction) -> Void in
                    })
                    AC.addAction(okBtn)
                    AC.addAction(noBtn)
                    cuurentView.present(AC, animated: true, completion: { _ in })
                }
                else{
                    let errorCode:Int = error._code;
                    if errorCode != -999 && errorCode != -1005{
                        NetworkManager.sharedInstance.dismissLoader()
                        cuurentView.view.isUserInteractionEnabled = true
                        let AC = UIAlertController(title: "Warning", message: error.localizedDescription, preferredStyle: .alert)
                        let okBtn = UIAlertAction(title: "Retry", style: .default, handler: {(_ action: UIAlertAction) -> Void in
                            taskCallback(2, "" as AnyObject)
                        })
                        let noBtn = UIAlertAction(title: "Cancel", style: .destructive, handler: {(_ action: UIAlertAction) -> Void in
                        })
                        AC.addAction(okBtn)
                        AC.addAction(noBtn)


                        cuurentView.present(AC, animated: true, completion: { _ in })
                   }else if errorCode == -1005{
                       NetworkManager.sharedInstance.dismissLoader()
                       taskCallback(2, "" as AnyObject)
                    }

                }
                break;

            }


        }

    }

在ViewController中时，我正在调用tokenRequest函数来创建从服务器授予的令牌。

func tokenRequest(){
    var tokenRequest = [String:String]();
    tokenRequest["Authorization"] = token_auth;
    tokenRequest["token_id"] = "token_id";
    tokenRequest["token_id"] = "token_id";
    NetworkManager.sharedInstance.callingHttpRequest(params:tokenRequest, apiname:"feed/api/gettoken", cuurentView: self){val,responseObject in
        if val == 1{
            print("responseobjec", responseObject)
            let dict = responseObject as! NSDictionary
            sharedPrefrence.set(dict.object(forKey: "access_token") as! String, forKey: "access_token")
            sharedPrefrence.synchronize();
            self.callingHttppApi()
        }else if val == 2{
            NetworkManager.sharedInstance.dismissLoader()
            self.loginRequest()
        }
    }
}

默认情况下，网络管理器具有Alamofire.request(urlString,method: .get,parameters:params)get方法，但是功能tokenRequest需要method: .post。

我在函数中添加方法发布

NetworkManager.sharedInstance.callingHttpRequest(params:loginRequest, apiname:"feed/rest_api/gettoken&grant_type=client_credentials", method: .post, cuurentView: self

这将返回错误“调用中的额外参数'方法'”。
