javascript - 实现自定义 ember-simple-auth 身份验证器

Question

首先，我不是经验丰富的 JS 开发人员，所以请原谅我可能犯的明显错误。

我正在尝试实现自定义身份验证器以使用 Keycloak 对用户进行身份验证使用需要将 client_id 作为请求正文的一部分传递的 OAuth2 密码授予。

import OAuth2PasswordGrant from 'ember-simple-auth/authenticators/oauth2-password-grant';
export default OAuth2PasswordGrant.extend({   
  serverTokenEndpoint: 'http://localhost:8080/something/token', 
  makeRequest(url, data, headers = {}) {
    data.client_id = 'my-app';
    return this._super(url, data, headers);
  }
});

我有一个 Controller 通过调用此操作来使用此 Authenticator:

actions: {
  authenticate() {
    let {username, password} = this.getProperties('username', 'password');
    this.get('session').authenticate('authenticator:oauth2', username, password).then(() => {
      // Do something
    }).catch((response) => {
      // Show error
    });
  }
}

这会导致 Firefox 挂起并给我一条无响应的脚本消息。

如果我从 makeRequest() 方法中删除 return ，我可以从浏览器调试器中看到对 Keycloak 的调用实际上正确地返回了包含我的对象 token 等。然而，ember 检查员显示了一些与 Unresolved promise 相关的错误。但我想那是因为我不再兑现 promise 。

我在这里做错了什么？

如何解决脚本无响应的问题？

还有其他方法可以实现我的目标吗？

编辑 1:这是我删除返回的时间

这是返回的实际对象:

Answer 1

实际上，您的解决方案看起来是正确的。

我猜你在服务器响应或请求方法不匹配方面有问题 GET/POST。要解决此问题，请尝试在 makeRequest 中调试 promise。

    return new RSVP.Promise((resolve, reject) => {
  fetch(url, options).then((response) => {
    response.text().then((text) => { //<-- here debug text 
      let json = text ? JSON.parse(text) : {};
      if (!response.ok) { //<-- and here debug response 
        response.responseJSON = json;
        reject(response);
      } else {
        resolve(json);
      }
    });
  }).catch(reject);

因此，如果这里出现问题，只需重写 makeRequest 的整个方法，并使用自定义 fetch 添加您自己的 promise 。

另一种方法是编写自定义 Authenticator，重写 authenticate、restore 和(可选)invalidate 方法作为在文档中写道:https://github.com/simplabs/ember-simple-auth#implementing-a-custom-authenticator
