WGET
The WGET function retrieves one or more URL files and saves them to a local directory.
This routine is written in the IDL language. Its source code can be found in the file wget.pro in the lib subdirectory of the IDL distribution.
Example
IDL> WGET('http://www.google.com/index.html',FILENAME='test.html')
C:\test.html
Syntax
Result = WGET( URL [, /BUFFER] [DIRECTORY=string] [FILENAME=string] [, /STRING_ARRAY] )
Return Value
By default, WGET returns a string (or string array) containing the full path(s) to the downloaded file(s).
If /BUFFER is set then WGET returns a byte array containing the contents of the URL file.
If /STRING_ARRAY is set then WGET returns a string array containing the contents of the URL file.
Arguments
URL
A scalar string or string array containing the URL of the file(s) to be downloaded.
Keywords
BUFFER
Set this keyword to return a byte array containing the contents of the URL file. This keyword can not be used with multiple URLs. If this keyword is set then the FILENAME keyword is ignored.
DIRECTORY
Set this keyword to a scalar string containing the local directory where the files should be saved. If DIRECTORY is not specified then the current working directory is used.
Note: If FILENAME contains a full path then the DIRECTORY keyword should not be used.
FILENAME
Set this keyword to a scalar string or string array containing the local file name(s) where the URL(s) should be saved. If multiple URLs are specified then FILENAME must have the same number of elements. If FILENAME is not specified then WGET will use the actual file name at the end of the URL.
STRING_ARRAY
Set this keyword to return a string array containing the contents of the URL file. This keyword can not be used with multiple URLs. If this keyword is set then the BUFFER and FILENAME keywords are ignored.
