[edk2-devel] [PATCH v7 1/1] ShellPkg/DynamicCommand: add HttpDynamicCommand
Vladimir Olovyannikov via groups.io

Tue Aug 25 17:20:49 UTC 2020
Introduce an http client utilizing EDK2 HTTP protocol, to
allow fast image downloading from http/https servers.
HTTP download speed is usually 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] [-s size] [-k]\r\n"
+" <URL> [localfilepath]\r\n"
+".SH OPTIONS\r\n"
+" \r\n"
+" -i interface - Specifies an adapter name, i.e., eth0.\r\n"
+" -k Keep the downloaded file even if there was an error.\r\n"
+" If this parameter is not used, the file will be deleted.\r\n"
+" -l port - Specifies the local port number. Default value is 0\r\n"
+" and the port number is automatically assigned.\r\n"
+" -s size The size of the download buffer for a chunk, in bytes.\r\n"
+" Default is 32K. Note that larger buffer does not imply\r\n"
+" better speed.\r\n"
+" -t timeout - The number of seconds to wait for completion of\r\n"
+" requests and responses. Default is 0 which is 'automatic'.\r\n"
+" %HURL%N\r\n"
+" Two types of providing of URLs are supported:\r\n"
+" 1. tftp-like, where host and http_uri are separate parameters\r\n"
+" (example: host /host_uri), and\r\n\"
+" 2. wget-like, where host and host_uri is one parameter.\r\n"
+" (example: host/host_uri)\r\n"
+"\r\n"
+" host - Specifies HTTP Server address.\r\n
+ Can be either IPv4 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"
+"\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 (use tftp-like URL format) :\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"
+" To get an index file from http://google.com and place it into the \r\n"
+" current directory:\r\n"
+" fs0:\> http google.com index.html\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"
+" 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, and -k parameter is on command line,
+" the file wil be saved either as localfilepath filename,\r\n"
+" or as an URI name in the current directory.\r\n"
+" If '/' is at the end of the URL, and no locafilepath filename\r\n"
+" is given on the command line, the file will be retrieved as\r\n"
+" index.html.\r\n"
