CORS和HTTP基本身份验证

Question

如果包含Basic auth,预检HTTP请求会如何？喜欢以下对话？我无法理解哪些标头需要发送到哪里,也因为无法使用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响应头中的特定源进行响应(因此不能使用通配符*).当然,它也需要响应Access-Control-Allow-Credentials响应头.
