Actix middleware can retrieve the response body and change the headers by implementing the Middleware
trait and implementing its fn response
method.
The response
method takes two arguments: a Request
object and a ServiceResponse
object. The ServiceResponse
object contains the response body and headers.
To retrieve the response body, middleware can call the response.take_body()
method, which consumes the ServiceResponse
object and returns the response body as a Body
object.
To change the headers, middleware can access the ServiceResponse
object's headers through its headers_mut()
method and modify them as needed.
Once the changes to the response body and headers have been made, the middleware can return a new ServiceResponse
object using the ServiceResponse::new()
method, passing in the modified headers and response body as arguments.
