【问题描述】：
我有一个 SPA，它使用提供的解决方案 here 向 Azure AD 进行身份验证，并且一切都按预期工作。现在我想迁移它以使用 MSAL.js。
我使用下面的登录方式：
import * as MSAL from 'msal'
...
const config = {
auth: {
tenantId: '<mytenant>.com',
clientId: '<myclientid>',
redirectUri: <redirecturi>,
},
cache: {
cacheLocation: 'localStorage',
}
};
const tokenRequest = {
scopes: ["User.Read"]
};
export default {
userAgentApplication: null,
/**
* @return {Promise}
*/
initialize() {
let redirectUri = config.auth.redirectUri;
// create UserAgentApplication instance
this.userAgentApplication = new MSAL.UserAgentApplication(
config.auth.clientId,
'',
() => {
// callback for login redirect
},
{
redirectUri
}
);
// return promise
return new Promise((resolve, reject) => {
if (this.userAgentApplication.isCallback(window.location.hash) || window.self !== window.top) {
// redirect to the location specified in the url params.
}
else {
// try pull the user out of local storage
let user = this.userAgentApplication.getUser();
if (user) {
resolve();
}
else {
// no user at all - go sign in.
this.signIn();
}
}
});
},
signIn() {
this.userAgentApplication.loginRedirect(tokenRequest.scopes);
},
然后我使用下面来获取令牌：
getCachedToken() {
var token = this.userAgentApplication.acquireTokenSilent(tokenRequest.scopes);
return token;
}
isAuthenticated() {
// getCachedToken will only return a valid, non-expired token.
var user = this.userAgentApplication.getUser();
if (user) {
// get token
this.getCachedToken()
.then(token => {
axios.defaults.headers.common["Authorization"] = "Bearer " + token;
// get current user email
axios
.get('<azureapi-endpoint>' + '/GetCurrentUserEmail')
.then(response => { })
.catch(err => { })
.finally(() => {
});
})
.catch(err => { })
.finally(() => { });
return true;
}
else {
return false;
}
},
}
但登录后出现以下错误：
Access to XMLHttpRequest at 'https://login.windows.net/common/oauth2/authorize?response_type=code+id_token&redirect_uri=<encoded-stuff>' (redirected from '<my-azure-api-endpoint>') from origin 'http://localhost:8080' 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.
我得到的令牌似乎也是无效的，因为我在尝试使用令牌调用 api 时遇到 401 错误。根据https://jwt.io/ 检查令牌后，我得到一个无效签名。
我非常感谢任何人的意见，因为我已经度过了好几天，但还没有任何结果。

似乎是 Azure 端的配置问题。
