post-url question

[Robert Gorenc]

dear all,
I'm new to this forum and Lisp also, I would like to send greetings to all!
I have a question about configuring header and parameters send in post-url.

when sending (post-url "http://ip.addr/cli/cgi-bin/exe.pl"
"param1=v1&param2=v2&param3=v3" "text/plain" 5000 "Content-Length: 50\r\nAuthorization: Basic encripted-user-psswd\r\n\r\n" )

in wireshark it looks very strange:
first packet:
POST /cli/cgi-bin/exe.pl HTTP/1.1\r\n
Request Method: POST
Request URI: /cli/cgi-bin/exe.pl
Request Version: HTTP/1.1

second:
Hypertext Transfer Protocol
Host: 10.243.117.12\r\n
Content-Length: 50
Authorization: Basic encrypted-user-psswd\r\n
\r\n
Data (50 bytes)

and there is response from server something like wrong user authorisation or similar...
If I omit in header part Content-Length, then server return error that content length is missing.

I would like to get something like this:
Hypertext Transfer Protocol
POST http://10.243.117.12/cli/cgi-bin/exe.pl HTTP/1.1\r\n
Request Method: POST
Request URI: http://10.243.117.12/cli/cgi-bin/exe.pl

Accept-Encoding: identity\r\n
Content-Length: 111
Authorization: Basic cmdvcmVuYzo3R2VsaXB0ZXI3\r\n
\r\n
folowed with:
Hypertext Transfer Protocol
Data (111 bytes)

0000 6e 65 5f 6e 61 6d 65 3d 4d 53 43 31 26 74 61 73 ne_name=MSC1&tas

Data: 6E655F6E616D653D4D534331267461736B5F747970653D54...
and after that is correct answer from server.

in python this can be done with request("POST", "http://ip.addr/cli/cgi-bin/exe.pl", params, headers)
describing params and headers as necessary.
Is it possible to get something like this with post-url?

This is how basic authorization is done for Twitter:

http://www.newlisp.org/syntax.cgi?code/twitter.txt

also referenced from here:

http://www.newlisp.org/index.cgi?Tips_and_Tricks

basically you have to Base 64 encode the authorization yourself:

Code: Select all

(set 'auth (append "Authorization: Basic " (base64-enc "john:secret") "\r\n"))
(get-url the-url 5000 auth)

Thanks Lutz,
Actually, user and psswd encription was not problem. But after Your message, I looked again in my header in post-url and found if remove second pair of \r\n, than post-url works as expected!!!
the working method is now:
(post-url "http://ip.addr/cli/cgi-bin/exe.pl"
"ne_name=msc1&task_type=TASK&ug_name=rgorenc&NEInputMethod=ViaNEName&Dang_Task=ON&taskname=statssp&method=inside" "" 10000 "Authorization: Basic encripted user-psswd\r\n" ) !!

thanks again,
Robert
