如何为登录系统创建Web服务? [英] How to create a webservice for a login system?

问题描述

我想知道是否可以使用Web服务创建登录系统，因为我需要在Smartface App Studio中的应用程序中添加登录系统?

I was wondering if it was possible to create a login system using a webservice as I need to add a login system in my app in Smartface App Studio?

谢谢

推荐答案

是的，有可能.
一种可能的解决方案是从服务器获取用户信息，并比较用户键入的密码和来自服务器的密码(如果相等)，请登录.我个人使用Firebase作为服务器，因此我保存了用户的密码.对象名称作为他的电子邮件，因此每次我想要获取该用户的对象时，我都会使用URL中的他的电子邮件发出GET请求.
例如

Yes, it's possible.
One of the possible solutions is to get the user's information from a server and compare the password that the user typed and the one that came from the server, if it's equal, log in. I personally use Firebase as my server, so I save user's object name as his email, so every time I want to get this user's object, I make a GET request with his email in the URL.
Eg.

var webclient = new SMF.Net.WebClient({
  URL : "https://exampleapp.firebaseio.com/Users/[e-mail]",
  httpMethod : "GET",
  ...
  onSyndicationSuccess : function(e){
    var response = JSON.parse(e.responseText);
    if(response.password === Pages.Page1.UserPassword.text){
      //Login
    } else {
      alert("Wrong Password!");
    }
  }
});

希望有帮助！ :)

                            //User logged, do something
                            callback();
                        } else {
                            //Password is wrong, do something

                        //User doesn't exist, do something
                    }
                },
                onServerError : function (e) {
                    //Server error, do something
                }
            });
        wcLogin.run(true);
    }
  }

将此代码放在全局范围内的某个地方(在空白区域)，当您要用户登录时，请使用firebase.login(someEmail, somePassword, callback)，其中callback是要在登录完成后运行的函数.并且，当您要注册用户时，请使用firebase.register(someEmail, somePassword, callback).

Put this code somewhere in global scope (in an empty space) and when you want the user to login, use firebase.login(someEmail, somePassword, callback), where callback is a function that you want to run when the login is finished. And when you want to register a user, use firebase.register(someEmail, somePassword, callback).

OBS.只要记住要在Firebase规则中更改auth值即可.

OBS. Just remember to change the auth value in Firebase rules.
