http - CORS 和 HTTP 基本身份验证

Question

如果包含基本身份验证，预检 HTTP 请求会是什么样子？喜欢下面的对话吗？我无法理解哪些标头需要发送到哪里，也因为它无法使用 Firebug 正确调试它

客户：

OPTIONS /api/resource HTTP/1.1
Access-Control-Request-Method: GET
Origin: http://jsconsole.com

服务器：

HTTP/1.1 200 OK
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST, GET, PUT, DELETE
Access-Control-Allow-Headers: Authorization
Access-Control-Max-Age: 1728000
Access-Control-Allow-Credentials: true

客户：

GET /api/resource HTTP/1.1
Access-Control-Request-Method: GET
Access-Control-Allow-Credentials: true
Origin: http://jsconsole.com

服务器：

HTTP/1.1 401 Unauthorized
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST, GET, PUT, DELETE
Access-Control-Allow-Headers: Authorization
Access-Control-Max-Age: 1728000
Access-Control-Allow-Credentials: true
WWW-Authenticate: Basic realm="Authorisation Required"

客户：

GET /api/resource HTTP/1.1
Access-Control-Allow-Credentials: true
Authorization: Basic base64encodedUserAndPassword
Access-Control-Request-Method: GET
Origin: http://jsconsole.com

服务器：

HTTP/1.1 200 OK
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST, GET, PUT, DELETE
Access-Control-Allow-Headers: Authorization
Access-Control-Max-Age: 1728000
Access-Control-Allow-Credentials: true

如果您正在请求凭据，则服务器必须使用 Access-Control-Allow-Origin 响应标头中的特定来源进行响应（因此不能使用通配符 *）。当然，它也需要使用 Access-Control-Allow-Credentials 响应标头进行响应。
