This is a simple algorithm that will download the contents of a url address to a file. It can support http:// and https:// based urls, and if the method is not supplied then http:// will be assumed. For example: If the address is www.mantidproject.org, then this will be adjusted to http://www.mantidproject.org.
Example - http
#import the os path libraries for directory functions
import os
#Create an absolute path by joining the proposed filename to a directory
#os.path.expanduser("~") used in this case returns the home directory of the current user
savefile = os.path.join(os.path.expanduser("~"), "DownloadedFile.txt")
DownloadFile("http://www.mantidproject.org", savefile)
print("File Exists: {}".format(os.path.exists(savefile)))
Output:
File Exists: True
Example - https
#import the os path libraries for directory functions
import os
#Create an absolute path by joining the proposed filename to a directory
#os.path.expanduser("~") used in this case returns the home directory of the current user
savefile = os.path.join(os.path.expanduser("~"), "DownloadedFile.txt")
DownloadFile("https://raw.githubusercontent.com/mantidproject/mantid/master/README.md", savefile)
print("File Exists:".format(os.path.exists(savefile)))
Output:
File Exists: True
