|
|
The Response() function queues an HTTP response to this HTTP instance, similar to
|
|
Receive() function in the EFI TCP driver. When the HTTP request is sent successfully,
|
|
or if there is an error, Status in token will be updated and Event will be signaled.
|
|
|
|
The HTTP driver will queue a receive token to the underlying TCP instance. When data
|
|
is received in the underlying TCP instance, the data will be parsed and Token will
|
|
be populated with the response data. If the data received from the remote host
|
|
contains an incomplete or invalid HTTP header, the HTTP driver will continue waiting
|
|
(asynchronously) for more data to be sent from the remote host before signaling
|
|
Event in Token.
|
|
|
|
It is the responsibility of the caller to allocate a buffer for Body and specify the
|
|
size in BodyLength. If the remote host provides a response that contains a content
|
|
body, up to BodyLength bytes will be copied from the receive buffer into Body and
|
|
BodyLength will be updated with the amount of bytes received and copied to Body. This
|
|
allows the client to download a large file in chunks instead of into one contiguous
|
|
block of memory. Similar to HTTP request, if Body is not NULL and BodyLength is
|
|
non-zero and all other fields are NULL or 0, the HTTP driver will queue a receive
|
|
token to underlying TCP instance. If data arrives in the receive buffer, up to
|
|
BodyLength bytes of data will be copied to Body. The HTTP driver will then update
|
|
BodyLength with the amount of bytes received and copied to Body.
|
|
|
|
If the HTTP driver does not have an open underlying TCP connection with the host
|
|
specified in the response URL, Request() will return EFI_ACCESS_DENIED. This is
|
|
consistent with RFC 2616 recommendation that HTTP clients should attempt to maintain
|
|
an open TCP connection between client and host.
