javascript - OAuth弹窗跨域安全React.js

Question

我对如何使用弹出窗口 (window.open) 在 React 中实现 OAuth 感兴趣。

例如我有:

1. mysite.com — 这是我打开弹出窗口的位置。
2. passport.mysite.com/oauth/authorize — 弹出窗口。

主要问题是如何在window.open(弹出窗口)和window.opener之间创建连接(众所周知，由于交叉，window.opener为空)域安全，因此我们不能再使用它)。

⇑ window.opener is removed whenever you navigate to a different host (for security reasons), there is no way around it. The only option should be doing the payment in a frame if it is possible. The top document needs to stay on the same host.

方案:

可能的解决方案:

1. 使用描述的 setInterval 检查打开的窗口 here .
2. 使用 cross-storage (恕我直言，不值得)。

建议者Khanh TO 。带有 localStorage 的 OAuth 弹出窗口。基于react-oauth-popup .

方案:

代码:

oauth-popup.tsx:

import React, {PureComponent, ReactChild} from 'react'

type Props = {
  width: number,
  height: number,
  url: string,
  title: string,
  onClose: () => any,
  onCode: (params: any) => any,
  children?: ReactChild,
}

export default class OauthPopup extends PureComponent<Props> {

  static defaultProps = {
    onClose: () => {},
    width: 500,
    height: 500,
    url: "",
    title: ""
  };

  externalWindow: any;
  codeCheck: any;

  componentWillUnmount() {
    if (this.externalWindow) {
      this.externalWindow.close();
    }
  }

  createPopup = () => {
    const {url, title, width, height, onCode} = this.props;
    const left = window.screenX + (window.outerWidth - width) / 2;
    const top = window.screenY + (window.outerHeight - height) / 2.5;

    const windowFeatures = `toolbar=0,scrollbars=1,status=1,resizable=0,location=1,menuBar=0,width=${width},height=${height},top=${top},left=${left}`;

    this.externalWindow = window.open(
        url,
        title,
        windowFeatures
    );

    const storageListener = () => {
      try {
        if (localStorage.getItem('code')) {
          onCode(localStorage.getItem('code'));
          this.externalWindow.close();
          window.removeEventListener('storage', storageListener);
        }
      } catch (e) {
        window.removeEventListener('storage', storageListener);
      }
    }

    window.addEventListener('storage', storageListener);

    this.externalWindow.addEventListener('beforeunload', () => {
      this.props.onClose()
    }, false);
  };

  render() {
    return (
      <div onClick={this.createPopup)}>
        {this.props.children}
      </div>
    );
  }
}

app.tsx

import React, {FC} from 'react'

const onCode = async (): Promise<undefined> => {
  try {
    const res = await <your_fetch>
  } catch (e) {
    console.error(e);
  } finally {
    window.localStorage.removeItem('code'); //remove code from localStorage
  }
}

const App: FC = () => (
  <OAuthPopup
    url={<your_url>}
    onCode={onCode}
    onClose={() => console.log('closed')}
    title="<your_title>">
    <button type="button">Enter</button>
  </OAuthPopup>
);

export default App;
