}

以下是接口的封裝

// MARK:- 請求AccessToken
extension NetworkTools{
    
    func loadAccessToken(code : String, finished : @escaping (_ result : [String :  Any]?, _ error : Error?) -> ()){
        // 1.獲取請求的URLString
        let urlString = "https://api.weibo.com/oauth2/access_token"
        // 2.獲取請求的參數
        let parameters = ["client_id" : app_key, "client_secret" : App_Secret, "grant_type" : "authorization_code", "redirect_uri" : redirect_uri, "code" : code]
        // 3.發(fā)送網絡請求
        request(methodType: .POST, urlString: urlString, parameters: parameters as [NSString : Any]) { (result, error) in
            finished(result as? [String : Any], error)
        }
    }
}

// MARK:- 請求用戶的信息
extension NetworkTools {
    
    func loadUserInfo(access_token : String,uid:String, finished : @escaping ( _ result : [String : Any]?,_ error:Error?) -> ()){
        let urlString = "https://api.weibo.com/2/users/show.json"
        let parameters = ["access_token" : access_token,"uid" : uid]
        request(methodType: .GET, urlString: urlString, parameters: parameters as [NSString : Any]) { (result, error) in
            finished(result as? [String : Any], error)
        }
    }
}
