|

|
|

|
|
The client accesses protected resources by presenting the access
|
||
|
|
token to the resource server. The resource server MUST validate the
|
||
|
|
access token and ensure that it has not expired and that its scope
|
||
|
|
covers the requested resource. The methods used by the resource
|
||
|
|
server to validate the access token (as well as any error responses)
|
||
|
|
are beyond the scope of this specification but generally involve an
|
||
|
|
interaction or coordination between the resource server and the
|
||
|
|
authorization server::
|
||
|
|
|
||
|
|
# For most cases, returning a 403 should suffice.
|
||
|
|
|
||
|
|
The method in which the client utilizes the access token to
|
||
|
|
authenticate with the resource server depends on the type of access
|
||
|
|
token issued by the authorization server. Typically, it involves
|
||
|
|
using the HTTP "Authorization" request header field [RFC2617] with an
|
||
|
|
authentication scheme defined by the specification of the access
|
||
|
|
token type used, such as [RFC6750]::
|
||
|
|
|
||
|
|
# Access tokens may also be provided in query and body

|
|
https://example.com/protected?access_token=kjfch2345sdf # Query
