To: devel, Ray Ni, Zhichao Gao; +Cc: Vladimir Olovyannikov
Introduce an http client utilizing EDK2 HTTP protocol, to
allow fast image downloading from http/https servers.
HTTP download speed is usually x30 times faster than tftp.
The client is based on the same approach as tftp dynamic command, and
uses the same UEFI Shell command line parameters. This makes it easy
integrating http into existing UEFI Shell scripts.
Note that to enable HTTP download, feature Pcd
gEfiNetworkPkgTokenSpaceGuid.PcdAllowHttpConnections must
be set to TRUE.

+".SH NAME\r\n"
+"Download a file from HTTP server.\r\n"
+".SH SYNOPSIS\r\n"
+" \r\n"
+"HTTP [-i interface] [-l <port>] [-t <timeout>]\r\n"
+" host[:port] http_uri [localfilepath]\r\n"
+".SH OPTIONS\r\n"
+" \r\n"
+" -i interface - Specifies an adapter name, i.e., eth0.\r\n"
+" -l port - Specifies the local port number. Default value is 0\r\n"
+" and the port number is automatically assigned.\r\n"
+" -t <timeout> - The number of seconds to wait for a response after\r\n"
+" sending a request packet. Default value is 0 which is 'automatic'.\r\n"
+" host - Specify HTTP Server IPv4 address.\r\n
+ Can be either address or 'http (or https)://addr'\r\n
+ Can use addresses resolvable by DNS as well. \r\n
+ Port can be specified after ':' if needed. \r\n
+ By default port 80 is used.\r\n"
+" http_uri - HTTP server URI to download the file.\r\n"
+" localfilepath - Local destination file path.\r\n"
+".SH DESCRIPTION\r\n"
+" \r\n"
+"NOTES:\r\n"
+" 1. The HTTP command allows geting of the file specified by its 'http_uri'\r\n"
+" path from the HTTP server specified by its 'host' IPv4 address. If the\r\n"
+" optional 'localfilepath' parameter is provided, the downloaded file is\r\n"
+" stored locally using the provided file path. If the local file path is\r\n"
+" not specified, the file is stored in the current directory using the file\r\n"
+" server's name.\r\n"
+" 2. Before using the HTTP command, the network interface intended to be\r\n"
+" used to retrieve the file must be configured. This configuration may be\r\n"
+" done by means of the 'ifconfig' command.\r\n"
+" 3. If a network interface is defined with the '-i' option then only this\r\n"
+" interface will be used to retrieve the remote file. Otherwise, all network\r\n"
+" interfaces are tried in the order they have been discovered during the\r\n"
+" DXE phase.\r\n"
+".SH EXAMPLES\r\n"
+" \r\n"
+"EXAMPLES:\r\n"
+" * To get the file "dir1/file1.dat" from the HTTP server 192.168.1.1, port 8080, and\r\n"
+" store it as file2.dat in the current directory :\r\n"
+" fs0:\> http 192.168.1.1:8080 dir1/file1.dat file2.dat\r\n"
+" * To get the file /image.bin via HTTPS from server 192.168.1.1 at port 443 \r\n"
+" (default HTTPS port), and store it in the current directory: \r\n"
+" fs0:\> http https://192.168.1.1 image.bin\r\n"
+".SH RETURNVALUES\r\n"
+" \r\n"
+"RETURN VALUES:\r\n"
+" SHELL_SUCCESS The action was completed as requested.\r\n"
+" SHELL_INVALID_PARAMETER One of the passed-in parameters was incorrectly\r\n"
+" formatted or its value was out of bounds.\r\n"
+" SHELL_HTTP_ERROR No EFI errors, but the server reported a status code\r\n
+ which should be treated as an error. If an error body sent\r\n
+ by the server, it would be saved as localfilepath parameter."

Hi Vladimir,
Sorry for the delay review.
CCS issue
Http.c - indent incorrect:
line 1546:
if (Context->URI[0] != L'/') {
DownloadUrl = StrnCatGrow (
&DownloadUrl,
&UrlSize,
L"/",
StrLen (Context->ServerAddrAndProto)
);
For Http.uni:
About the help content, can you add the description of the option "-p" "-s".
Build error:
Http.c:
Line 509:
HttpConfigData.TimeOutMillisec = ShellStrToUintn (ValueStr);
=>
HttpConfigData.TimeOutMillisec = (UINT32) ShellStrToUintn (ValueStr);
Vladimir,
Did you do some unitest or functional test on this function?
Hi Siyuan/Jiaxin,
I can only review the part of the shell. Except the above issue, the part to parse the shell argument is OK to me.
Example:
http/http.efi 192.168.1.1/https://192.168.1.1 a.bin [b.bin] [-i interface] [-l local_port] [-p proxy] [-s buffer_size] [-t timeout_str]
After parse the argument, below data would be initialized:
Context.ServerAddrAndProto = http://192.168.1.1 or the specific protocol (like https://192.168.1.1)
Context.URI = a.bin
DownlaodUrl = http://192.168.1.1/a.bin
HttpConfigData.AccessPoint.IPv4Node.LocalPort = UINT16 localport value. Default value - 0.
Context.ProxyServerAddr = ascii proxy address. Default value - NULL.
Context.BufferSize = UINTN buffer_size. Default value - 32KB
HttpConfigData.timeOutMillisec = UINT32 timeout value. Default value - 10.
Interface name indicates to connect to the specific Nic name. Default - try to connect all Nic.
Can you help to view the part of http implementation with the above parameters?
Thanks,
Zhichao

> +".SH NAME\r\n"
> +"Download a file from HTTP server.\r\n"
> +".SH SYNOPSIS\r\n"
> +" \r\n"
> +"HTTP [-i interface] [-l <port>] [-t <timeout>]\r\n"
> +" host[:port] http_uri [localfilepath]\r\n"
> +".SH OPTIONS\r\n"
> +" \r\n"
> +" -i interface - Specifies an adapter name, i.e., eth0.\r\n"
> +" -l port - Specifies the local port number. Default value is 0\r\n"
> +" and the port number is automatically assigned.\r\n"
> +" -t <timeout> - The number of seconds to wait for a response after\r\n"
> +" sending a request packet. Default value is 0 which is
> 'automatic'.\r\n"
> +" host - Specify HTTP Server IPv4 address.\r\n
> + Can be either address or 'http (or https)://addr'\r\n
> + Can use addresses resolvable by DNS as well. \r\n
> + Port can be specified after ':' if needed. \r\n
> + By default port 80 is used.\r\n"
> +" http_uri - HTTP server URI to download the file.\r\n"
> +" localfilepath - Local destination file path.\r\n"
> +".SH DESCRIPTION\r\n"
> +" \r\n"
> +"NOTES:\r\n"
> +" 1. The HTTP command allows geting of the file specified by its 'http_uri'\r\n"
> +" path from the HTTP server specified by its 'host' IPv4 address. If the\r\n"
> +" optional 'localfilepath' parameter is provided, the downloaded file is\r\n"
> +" stored locally using the provided file path. If the local file path is\r\n"
> +" not specified, the file is stored in the current directory using the file\r\n"
> +" server's name.\r\n"
> +" 2. Before using the HTTP command, the network interface intended to
> be\r\n"
> +" used to retrieve the file must be configured. This configuration may be\r\n"
> +" done by means of the 'ifconfig' command.\r\n"
> +" 3. If a network interface is defined with the '-i' option then only this\r\n"
> +" interface will be used to retrieve the remote file. Otherwise, all
> network\r\n"
> +" interfaces are tried in the order they have been discovered during the\r\n"
> +" DXE phase.\r\n"
> +".SH EXAMPLES\r\n"
> +" \r\n"
> +"EXAMPLES:\r\n"
> +" * To get the file "dir1/file1.dat" from the HTTP server 192.168.1.1, port 8080,
> and\r\n"
> +" store it as file2.dat in the current directory :\r\n"
> +" fs0:\> http 192.168.1.1:8080 dir1/file1.dat file2.dat\r\n"
> +" * To get the file /image.bin via HTTPS from server 192.168.1.1 at port 443
> \r\n"
> +" (default HTTPS port), and store it in the current directory: \r\n"
> +" fs0:\> http https://192.168.1.1 image.bin\r\n"
> +".SH RETURNVALUES\r\n"
> +" \r\n"
> +"RETURN VALUES:\r\n"
> +" SHELL_SUCCESS The action was completed as requested.\r\n"
> +" SHELL_INVALID_PARAMETER One of the passed-in parameters was
> incorrectly\r\n"
> +" formatted or its value was out of bounds.\r\n"
> +" SHELL_HTTP_ERROR No EFI errors, but the server reported a status
> code\r\n
> + which should be treated as an error. If an error body sent\r\n
> + by the server, it would be saved as localfilepath parameter."

I tested on Aarch64 (RPi4) and the command seems to work well.
One question: why is the input arguments "host[:port]" and the remote file "http_uri" not treated as a single "http_uri" argument?
For example, instead of:
fs0:\> http http://192.168.1.1:8080 dir1/file1.dat file2.dat
Why not:
fs0:\> http http://192.168.1.1:8080/dir1/file1.dat file2.dat

> +".SH NAME\r\n"
> +"Download a file from HTTP server.\r\n"
> +".SH SYNOPSIS\r\n"
> +" \r\n"
> +"HTTP [-i interface] [-l <port>] [-t <timeout>]\r\n"
> +" host[:port] http_uri [localfilepath]\r\n"
> +".SH OPTIONS\r\n"
> +" \r\n"
> +" -i interface - Specifies an adapter name, i.e., eth0.\r\n"
> +" -l port - Specifies the local port number. Default value is 0\r\n"
> +" and the port number is automatically assigned.\r\n"
> +" -t <timeout> - The number of seconds to wait for a response after\r\n"
> +" sending a request packet. Default value is 0 which is
> 'automatic'.\r\n"
> +" host - Specify HTTP Server IPv4 address.\r\n
> + Can be either address or 'http (or https)://addr'\r\n
> + Can use addresses resolvable by DNS as well. \r\n
> + Port can be specified after ':' if needed. \r\n
> + By default port 80 is used.\r\n"
> +" http_uri - HTTP server URI to download the file.\r\n"
> +" localfilepath - Local destination file path.\r\n"
> +".SH DESCRIPTION\r\n"
> +" \r\n"
> +"NOTES:\r\n"
> +" 1. The HTTP command allows geting of the file specified by its
> 'http_uri'\r\n"
> +" path from the HTTP server specified by its 'host' IPv4 address. If the\r\n"
> +" optional 'localfilepath' parameter is provided, the downloaded file is\r\n"
> +" stored locally using the provided file path. If the local file path is\r\n"
> +" not specified, the file is stored in the current directory using the file\r\n"
> +" server's name.\r\n"
> +" 2. Before using the HTTP command, the network interface intended to
> be\r\n"
> +" used to retrieve the file must be configured. This configuration may
> be\r\n"
> +" done by means of the 'ifconfig' command.\r\n"
> +" 3. If a network interface is defined with the '-i' option then only this\r\n"
> +" interface will be used to retrieve the remote file. Otherwise, all
> network\r\n"
> +" interfaces are tried in the order they have been discovered during
> the\r\n"
> +" DXE phase.\r\n"
> +".SH EXAMPLES\r\n"
> +" \r\n"
> +"EXAMPLES:\r\n"
> +" * To get the file "dir1/file1.dat" from the HTTP server 192.168.1.1, port
> 8080, and\r\n"
> +" store it as file2.dat in the current directory :\r\n"
> +" fs0:\> http 192.168.1.1:8080 dir1/file1.dat file2.dat\r\n"
> +" * To get the file /image.bin via HTTPS from server 192.168.1.1 at port 443
> \r\n"
> +" (default HTTPS port), and store it in the current directory: \r\n"
> +" fs0:\> http https://192.168.1.1 image.bin\r\n"
> +".SH RETURNVALUES\r\n"
> +" \r\n"
> +"RETURN VALUES:\r\n"
> +" SHELL_SUCCESS The action was completed as requested.\r\n"
> +" SHELL_INVALID_PARAMETER One of the passed-in parameters was
> incorrectly\r\n"
> +" formatted or its value was out of bounds.\r\n"
> +" SHELL_HTTP_ERROR No EFI errors, but the server reported a status
> code\r\n
> + which should be treated as an error. If an error body
> sent\r\n
> + by the server, it would be saved as localfilepath parameter."

The idea was to make it 100% compatible with tftp command.
This way, one could easily support both in one script like this:
set -v eth_int " -i eth0"
...
# Set update protocol on some low-level init
set upd_proto http (or tftp, or something else if needed and supported)
...
# Set protocol-specific parameters
if "%u_proto%" == "tftp" then
set -v tftp_blk_param " -s %tftp_blocksize%"
set -v tftp_win_param " -w %tftp_windowsize%"
endif
...
# "Universalize" transfer command
set -v transfer_cmd "%u_proto% %eth_int% %tftp_blk_param% %tftp_win_param%
%serverip% %tftp_dir%"
...
# Use universal transfer command with no changes for any update protocol
(be it tftp, http, etc.).
%transfer_cmd%/md5sum.txt %esp_root%\md5sum.txt
...
Thanks,
Vladimir

If
> the\r\n"

path is\r\n"

using the
> file\r\n"
> > +" server's name.\r\n"
> > +" 2. Before using the HTTP command, the network interface intended
to

> > +" used to retrieve the file must be configured. This
configuration may
> > be\r\n"
> > +" done by means of the 'ifconfig' command.\r\n"
> > +" 3. If a network interface is defined with the '-i' option then
only
> this\r\n"
> > +" interface will be used to retrieve the remote file. Otherwise,
all
> > network\r\n"

Thanks Vladimir for the explanation.
Wondering what is more useful to users:
1- Having the 'http' and 'tftp' commands share a common interface to make it easier to script using either tool/protocol (as explained below)
Or
2- Having a more natural support for URIs in 'http' command, similar to what is common in other http CLI clients like curl
If (1) is important enough for users, then could we entertain adding (2) in addition to (1).
Thanks,
--Samer

Thank you for the feedback Samer,
Well, (1) is important for us as we use universal UEFI Shell scripts for
multiple images updates from any media (usb, network(http/tftp), etc.)
I agree that adding (2) to (1) makes sense. Would be nice to get more
feedback from edk2 community on that.
Thank you,
Vladimir

I think the NetworkPkg maintainer can give a better comment and the remain part of the implementation need their help to review.
Hi Jiaxin/Siyuan,
Do you have any comments on this? And the implementation is part of NetworkPkg protocol usage. I am not familiar with this. Please help to review.
Thanks,
Zhichao

Oh. Should follow "5.2.2.4 Subsequent lines of multi-line function calls
should line up two spaces from the beginning of the function name"

"-s".
-p option is actually a placeholder, removing it. I am using HttpDxe and I
don't see an easy way to get
this mode using proxy, working, as HttpDxe does not support building of
"GET http://.... HTTP/1.1" request.
Will add description for -s option.

OK, thanks., will fix.

Zhichao, other than running a static (Coverity) test on
HttpDynamicCommand,
no specific tests were performed.
HttpDynamicCommand is used by all our update procedures as it is ~30
times faster than tftp for us.

to

> > +" used to retrieve the file must be configured. This
configuration may
> be\r\n"
> > +" done by means of the 'ifconfig' command.\r\n"
