node.js - 在loopbackjs应用程序上注册新用户

Question

这个问题我已经查过了。但答案与我正在寻找的不太相符。 Extend built-in User model to support more properties and behaviors in loopback

我正在尝试做的事情:在我的测试应用程序上注册一个新用户。我只需要在点击注册时将数据保存到mysql数据库即可。环回文档中用于注册新用户的大多数示例都来自启动脚本。并且这里的示例没有将其保存到数据库 - https://github.com/strongloop/loopback-example-user-management 。这更多是一个问题，为什么我无法将其保存到数据库中，而不能保存到寄存器或用户模型上。但模型 userAccount 是从 User 基础模型扩展而来的。所以我不确定这是否有不同的工作方式。我仍然不完全熟悉 Loopback 框架，因此非常感谢任何帮助。谢谢。

背景将环回 3.0 与 NodeJS 8.1.0 结合使用。使用的连接器 - Loopback-connector-mysql 连接到 Azure 上托管的 MySQL 数据库。

使用loopback创建的POST/userAccounts(默认API端点)可以连接到数据库并保存用户。我只是在使用远程方法 POST/register 时遇到了问题。

Answer 1

What I am trying to do: Register a new user on my test application. I just need to save the data to mysql database when I click register.

默认的User模型允许$everyone创建用户模型。这意味着创建用户最简单的行为就是发布到/api/Users/create。

Most of the examples on the loopback documentation to register new user, is from a boot script. And the example here does not save it to database - https://github.com/strongloop/loopback-example-user-management.

这是因为连接器是内存中连接器，您可以交换任何持久数据源，并且用户将持续存在。

This is more of a problem on why I am not able to save it to database and not so much on the register or user models. But the model userAccount extends from the User base model. So I am not sure if this works differently. I am still not completely familiar with Loopback framework, so any help is greatly appreciated. Thanks.

为了解决您的错误，您正在调用 userAccount(您在函数中创建的类)上的 save 方法，您可能想在 上调用它>usersHR.

旧:

userAccount.save(newUserAccount, function(err) {
        if (err) {
          console.log(err);
        } else {
          console.log('User registered');
        }
      });

新:

usersHR.save(newUserAccount, function(err) {
        if (err) {
          console.log(err);
        } else {
          console.log('User registered');
        }
      });
