如何解决 OKTA 托管注销上的 CORS 错误

Question

我正在尝试将 OKTA 添加到我的 React 应用程序中。我已经登录，可以正常工作。但我正在为注销而苦苦挣扎。

设置：我按照 OKTA 的这些说明将 OKTA 添加到我的项目中。

这大部分有效，但包括这些调用登录的说明

  const { authState, authService } = useOktaAuth();
  const login = () => authService.login('/profile');

authService找不到。所以我去了OKTA示例并将其更改为

  const { authState, oktaAuth } = useOktaAuth();
  const login = async () => oktaAuth.signInWithRedirect();

这也意味着

authService.signOut();

变成

oktaAuth.signOut();

问题：正如我上面所说，我可以正常登录。authState.isAuthenticated解析为 True。

但是，当我尝试退出时，React 报告“未处理的拒绝（AuthApiError）”错误：

控制台报告这些错误：

Access to XMLHttpRequest at 'https://dev-7869221.okta.com/oauth2/default/v1/revoke' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

POST https://dev-7869221.okta.com/oauth2/default/v1/revoke net::ERR_FAILED

Uncaught (in promise) AuthApiError

我克隆了 OKTA 示例代码，并在我的应用程序详细信息中进行了硬编码。登录/注销在演示应用程序上运行良好。当我注销配置对象时，它们匹配。所以我得出结论：

• 我的 OKTA 应用程序配置正确。
• 示例应用程序正在做一些我没有注意到的事情
• OKTA 文档对于这些详细信息已经过时。

为了完整起见，我的源代码和 package.json 如下。该应用程序是create-react-app使用打字稿模板创建的。

export const config = {
    clientId,
    issuer: `https://${domain}/oauth2/default`,
    redirectUri: 'http://localhost:3000/login/callback',
    scopes: ['openid', 'profile', 'email'],
    pkce: true,
    disableHttpsCheck: false,
};

const oktaAuth = new OktaAuth(config);

const CALLBACK_PATH = '/login/callback';

function App() {
    return (
        <Router>
            <Security oktaAuth={oktaAuth}>
                <Switch>
                    <Route path={CALLBACK_PATH} component={LoginCallback}/>
                    <Route path={'/'} component={Main} exact/>
                    <Route path={'/orgList'} component={OrgList}/>
                </Switch>
            </Security>
        </Router>
    );
}

export default App;

import React from 'react';
import { useOktaAuth } from '@okta/okta-react';

function Main() {
    const { authState, oktaAuth } = useOktaAuth();

    const login = async () => oktaAuth.signInWithRedirect();
    const logout = async () => oktaAuth.signOut();

    if( authState.isPending ) {
        return (
            <>
                <div>Loading authentication...</div>
            </>
        );
    } else if( !authState.isAuthenticated ) {
        return (
            <>
                <div>
                    <button onClick={login}>Login</button>
                </div>
            </>
        );
    }
    return (
        <>
            <button onClick={logout}>Logout</button>
        </>
    );
}

您需要在 Okta 中添加您的主机名作为“可信来源”。为此，请登录 Okta Admin > Security > API > Trusted Origins > 单击 Add Origin 并输入您的应用程序 URL，例如http://127.0.0.1:3000
