websave() adds '.html' to file even though the file extension is specified.

This question has been asked before https://www.mathworks.com/matlabcentral/answers/525706-websave-adds-html-to-file-name . However, this person's error was not adding the file extension to the name of the file to be downloaded. I am doing that in this case. The website is 'https://cddis.nasa.gov/archive/gnss/data/hourly/2023/008/19/AMC400USA_R_20230081900_01H_GN.rnx.gz' and the filename is 'AMC400USA_R_20230081900_01H_GN.rnx.gz'. When I call websave() it adds the HTML extension.

url='https://cddis.nasa.gov/archive/gnss/data/hourly/2023/008/19/AMC400USA_R_20230081900_01H_GN.rnx.gz'
fname = 'AMC400USA_R_20230081900_01H_GN.rnx.gz'
websave(fname,url)

The downloaded file is 'AMC400USA_R_20230081900_01H_GN.rnx.gz.html'. I have tried gunzip(url) because the file is GNU compressed but the downloaded file is just an HTML doc without the .gz extension.

It is the login page. You need to create weboptions with your username and password and pass those to websave() after the url. (There might be additional steps as well; I do not have an account there to test it myself.)

Hi. The only reason I didn't need to do that originally is becuase I was already logged in to the website. I cleared my brower cache and cookies and created the weboptions structure, and the result was the same. You are more than welcome to try this yourself with the username and password below as the account has no personal information on it. The data is available to anyone and not restricted. You just have to have an account.

fname = 'AMC400USA_R_20230081900_01H_GN.rnx.gz'
options = weboptions('Username','[e-mail]','Password','P@$$w0rD');
websave(fname,url,options)
