Authentication syntax for HTTP GET method using TCP functions in Labview on linux

[SS21]

Hi,

Currently, I am trying to communicate to web server. I have Labview installed on a Linux machine. The HTTP function blocks and other labview functions do not work. Hence, I am building a HTTP code string using TCP functions (port 80) to talk to the web server. I am successfully able to fetch a response from web sites (example www.ni.com) from my vi. However, when I try to communicate to my web server, it does not work. It requires an authentication. I am able to open http://ipaddress in my browser from my machine using username and password. Can someone help with Authentication string requirement for GET method?

so far the string is:

GET /index/ HTTP/1.1

Host: http://xx.xx.xx.xx

Hi SS21,

this link should help to solve your problem.

An easy option would be to try http://user:password@server syntax for the URL.

Else I posted a Twitter fetcher once (won't work anymore since Twitter moved to Oauth authentication) at LAVA. Based on code from @cloew.

The code is part of this LLB.

Thanks for all your replies.

MikeS81, your link helped understand the authentication structure, I have added the basic athentication string as part of my GET method string.

TCPlomp, the Base64 conversion in your LLB looks like something I can definitely incorporate for my username and password strings for authentication. I really appreciate you sharing this part of the code.

I will definitely try it out and hope it works.
