我目前正在尝试向 login.microsoftonline/发送帖子请求XXX / oauth2 / token 端点，用于检索应用程序的访问令牌和刷新令牌。使用axios将发布请求发送到端点时，会发送预检，但不会返回任何响应。

Im currently trying to send a post request to login.microsoftonline/XXX/oauth2/token endpoint to retrieve an access token and refresh token for an application. When sending the post request to the endpoint using axios, the preflight is sent off, however no response is returned.

错误：

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'localhost:3000' is therefore not allowed access.

然而，对于axios post请求使用不同的方法，它返回数据但没有预检并给出一个不同的错误：

However using a different approach to the axios post request, it returns the data but has no preflight and gives the a different error:

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'localhost:3000' is therefore not allowed access.

两个Axios请求：

const data = new FormData(); data.append('grant_type', this.config.grant_type); data.append('client_id', this.config.client_id); data.append('code', localStorage.getItem('auth_code')); data.append('redirect_uri', this.config.redirect_uri); data.append('client_secret', this.config.client_secret); data.append('resource', this.config.client_id); axios.post(`login.microsoftonline/${this.config.tenant}/oauth2/token`, data);

方法2：

axios({ method: 'post', contentType: 'application/json', url: `login.microsoftonline/${this.config.tenant}/oauth2/token`, data: { grant_type: this.config.grant_type, client_id: this.config.client_id, code: localStorage.getItem('auth_code'), redirect_uri: this.config.redirect_uri, client_secret: this.config.client_secret, resource: this.config.client_id } });

这是axios请求本身或端点的问题吗？

Is this a problem with the axios request itself or with the endpoint?

推荐答案

您需要使用隐式授权流来获取访问令牌。您不能使用来自前端JavaScript的授权代码流！

You need to use the Implicit Grant flow to get the access token. You cannot use authorization code flow from front-end JavaScript!

您的客户机密（AKA您的应用密码）目前公开给任何访问者您的网站！

Your client secret (AKA your app's password) is currently public to anyone who visits your site!

您无法在前端JavaScript中使用客户端密钥。

You cannot use a client secret in front-end JavaScript.

您需要在应用程序的清单中启用隐式流，然后在您的应用程序中使用以下URL重定向到Azure AD：

You will need to enable implicit flow in the app's manifest, and then in your app make a redirect to Azure AD with a URL like this:

login.microsoftonline/tenant-id-here/oauth2/authorize?client_id=your-client-id&response_type=id_token+token&resource=resource-id-for-api&redirect_uri=your-app-redirect-url
