我正在尝试使用提取API在我的应用程序中发送请求,并且如果收到401 Unauthorized
响应,我想读取WWW-Authenticate
响应标头的值。这在Chrome上可以正常运行,但是在Firefox上,即使我的回复的WWW-Authenticate
标头中包含了Access-Control-Expose-Headers
标头,我也看不到。
我的代码:
const api = async (endpoint, fetchOptions) => {
// fetchOptions:
// {
// "credentials": "same-origin",
// "method": "GET",
// "headers": {
// "Accept": "application/json",
// "Content-Type": "application/json"
// }
// }
const response = await fetch(endpoint, fetchOptions)
.catch(r => r)
.then(r => { r.headers.forEach(console.log.bind(console)); return r; });
// handle 401 errors
if (!response.status === 401 && response.headers.has('WWW-Authenticate')) {
const authenticate = response.headers.get('WWW-Authenticate');
const authEndpoint = authenticate.match(/authorization_endpoint="([^"]+)/i)[1];
window.location.href = authEndpoint;
return;
}
};
我的要求:
GET /api/login HTTP/1.1

有人知道为什么Firefox无法读取该响应标头吗?

存在一个已知错误,其中包含多个WWW-Authenticate响应头,您可能会遇到以下问题:https://bugzilla.mozilla.org/show_bug.cgi?id=1491010。
