MSAL 2.*.js 是否适用于 IE 11？

Question

我已经按照此处提到的相同方式实施了 SPA - https://docs.microsoft.com/en-us/azure/active-directory/develop/tutorial-v2-javascript-spa#configure-your-javascript-spa

我已经根据 - https://github.com/Azure-Samples/active-directory-b2c-javascript-msal-singlepageapp/issues/61#issuecomment-630953375

更改了代码

我的代码仍然无法在 IE 11 上运行。与上述代码唯一不同的是我使用的是 MSAL 2.13。1.js。

2.*.js 是否适用于 IE11？

我用过的代码如下。它不会重定向到 IE 11 中的 Microsoft 登录页面。它在 chrome 和 edge.

中工作正常

Answer 1

简而言之：是的。 MSAL 2.0 支持 IE。但是，它确实需要一个 Promise polyfill 来做到这一点，但它不包括在内。

What browsers are supported by MSAL.js?
MSAL.js has been tested and supports the last 2 stable and supported versions of the following browsers:

Chrome

Edge (Chromium)

Firefox

Safari

Opera

MSAL.js has also been tested and supports the following browsers with Promise polyfills (not included):

IE 11

Edge (Legacy)

Answer 2

问题是 msalConfig 应该在 myMSALObj 之上。

var msalConfig = {
                    auth: {
                        clientId: "XXXXXXXXXXXXXXXXXXXXXXXXX",
                        authority: "https://login.microsoftonline.com/XXXXXXXXXXXXXX",
                        redirectUri: "https://localhost:44342/Ie11.html"
                    },
                    cache: {
                        cacheLocation: "sessionStorage",
                        // This configures where your cache will be stored
                        storeAuthStateInCookie: true // Set this to "true" if you are having issues on IE11 or Edge
        
                    }
                };
var myMSALObj = new msal.PublicClientApplication(msalConfig);
                var username = "";
