Modifying the User-Agent header using httpie is shown below – Passing custom HTTP headers is intuitive using httpie, installation and usage details can be accessed here. In addition to wget or curl, a much easier to use CLI HTTP client httpie can be used. You can use below commands to change the User-Agent parameter – curl is an alternative to wget, which can download files from HTTP requests, but can also print the results of a metadata request to the screen, which can be. Both curl and wget support the altering of User-Agent header field. So the trick was to simply modify the User-Agent to a ‘legitimate’ one. It seems that the website was blocking access from client browsers with certain ‘User-Agent’ header field. What was surprising is that I could download the files using Firefox, Internet Explorer, elinks and even text based browser ‘lynx’. wget can recover from a prematurely broken transfer and continue downloading. You don't have permission to access /dir/names.txt on this server. Wgets major strong side compared to curl is its ability to download recursively, or even just download everything that is referred to from a remote resource, be it a HTML page or a FTP directory listing. Instead, it contained an html file with 403 Forbidden message. It turned out that Curl would actually create a file with the same name as the one being download, but to my surprise the file was not downloaded. Then hoping that this was just a wget problem, I replaced wget with curl. Wget enables more features by default: cookies, redirect. cURL performs Transfer-Encoded HTTP decompressions, while wget does not. cURL supports multiple parallel transfers. Wget is natively available in Linux systems, while cURL is readily available in Windows systems. Recursive downloads are not supported in curl. With in the script, first I used wget to retrieve the files, but I kept on getting the following error message – Wgets major strong side compared to curl is its ability to download recursively, or even just download everything that is referred to from a remote resource, be it a HTML page or a FTP directory listing. Wget supports fewer protocols compared to cURL. LAAD DAAC issue.PNG (113.Recently I was trying to download numerous files from a certain website using a shell script I wrote. I've included a cmd window to give you a better idea of the situation. So, wget is predominantly website-centric, while cURL is something that operates at a deeper level, down at the plain-vanilla internet level. Finally, I resubmitted the order, but I ran into the same issue, which I assume is due to the fact that the data I downloaded there is not geographically subset and is not in Gtiff format. Please keep in mind that I attempted to download them manually by following the instructions, but it did not work and I had the same issue. The issue is that wget cannot access the files because it receives a 404 ERROR (.tif file not available for download), despite the fact that wget can reach your server since it downloaded the README GLDAS2.pdf file. I submitted the order and received an email with a link to the data and a wget script I followed the instructions in the email and added a new token. The data is subsetted in the Middle East, and I am trying to download only four tiles covering Iraq, which I mosaiced, converted to Gtiff format, then reprojected to Geographic. I'm using Windows 10 and wget 1.21.3 64bit to get data from the LAAD DAAC Data Collection MYD021KM. ), so maybe there's an added authentication step that I'm missing?

I either get "504 Gateway Time-out" or "401 Username/Password Authentication failed" errors (only timeouts with curl, both errors with wget - first a 504 then 401). html.tmp -nH -cut-dirs=3 " " -header "Authorization: Bearer $TOKEN" -P. I am unable to get *any* scripts (either my own or the templates provided by LAADS DAAC tutorials) to complete a download.Ĭurl -v -H 'Authorization: Bearer $TOKEN' ' ' >. I have done this many times in the past, but it's been about a year since my last attempt. I need to batch download MYD06_L2 and MYD03 files over a specific geographic region.
