Json 如何使用Swift和Alamofire连接http服务器

嗨，我是swift的新手，我的服务器连接有问题。我正在尝试使用post方法请求使用用户名和密码登录到服务器。如何连接到服务器并进行身份验证

错误消息：

 ["id": <null>, "error": {
    code = "-32700";
    message = "Parse error";
}, "jsonrpc": 2.0]

我需要获取的服务器上的Json：

{"jsonrpc":"2.0","id":1,"result":[0,{"ubus_rpc_session":"07e111d317f7c701dc4dfde1b0d4862d","timeout":300,"expires":300,"acls":{"access-group":{"superuser":["read","write"],"unauthenticated":["read"]},"ubus":{"*":["*"],"session":["access","login"]},"uci":{"*":["read","write"]}},"data":{"username":"root"}}]}

请求应该如下所示：

"{ \"jsonrpc\": \"2.0\", \"id\": 1, \"method\": \"call\", \"params\": [ \"00000000000000000000000000000000\", \"session\", \"login\", { \"username\": \"root\", \"password\": \"admin01\"  } ] }"

请尝试使用以下代码：

 Alamofire.request(url, method: .post, parameters: parameters).responseJSON { response in
                    if(response.result.isFailure){
                        print("no data!");

                    }else{
                      print("received data!");

// make sure we got some JSON since that's what we expect
            guard let json = response.result.value as? [String: Any] else {
                print("didn't get todo object as JSON from API")
                print("Error: \(response.result.error)")
                return
            }

            print(json)
                    }
                }

尝试将let param:[String:Any]更改为let param:[String:String]这两次尝试了，没有帮助您尝试在浏览器中点击您的url吗？基本上，此url是路由器，url不在浏览器上工作，但使用android和请求它的工作完美见：我得到：收到数据！这意味着这是可行的。现在把你的代码放在那里，然后我尝试打印结果json，我得到相同的错误代码=“-32700”；message=“解析错误”；}；id=“”；jsonrpc=“2.0”@然后，您需要正确地检查JSON格式。Parse error表示解析JSON时出现了问题。我将在我的问题请求中添加terminal和我应该得到的JSON，你能帮我吗？

 Alamofire.request(url, method: .post, parameters: parameters).responseJSON { response in
                    if(response.result.isFailure){
                        print("no data!");

                    }else{
                      print("received data!");

// make sure we got some JSON since that's what we expect
            guard let json = response.result.value as? [String: Any] else {
                print("didn't get todo object as JSON from API")
                print("Error: \(response.result.error)")
                return
            }

            print(json)
                    }
                }
