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">http://ip.addr/cli/cgi-bin/exe.pl"

"param1=v1&param2=v2&param3=v3" "text/plain" 5000 "Content-Length: 50rnAuthorization: Basic encripted-user-psswdrnrn" )



in wireshark it looks very strange:

first packet:

POST /cli/cgi-bin/exe.pl HTTP/1.1rn

   Request Method: POST

   Request URI: /cli/cgi-bin/exe.pl

   Request Version: HTTP/1.1

   

second:

Hypertext Transfer Protocol

    Host: 10.243.117.12rn

    Content-Length: 50

    Authorization: Basic encrypted-user-psswdrn

    rn

    Data (50 bytes)



0000  43 6f 6e 6e 65 63 74 69 6f 6e 3a 20 63 6c 6f 73   Connection: clos

        Data: 203131310D0A0D0A6E655F6E616D653D6D73633126746173...

       

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://10.243.117.12/cli/cgi-bin/exe.pl HTTP/1.1rn

        Request Method: POST

        Request URI: http://10.243.117.12/cli/cgi-bin/exe.pl">http://10.243.117.12/cli/cgi-bin/exe.pl

        Request Version: HTTP/1.1

    Host: 10.243.117.12rn

    Accept-Encoding: identityrn

    Content-Length: 111

    Authorization: Basic cmdvcmVuYzo3R2VsaXB0ZXI3rn

    rn

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

0010  6b 5f 74 79 70 65 3d 54 41 53 4b 26 75 67 5f 6e   k_type=TASK&ug_n

...

0060  70 26 6d 65 74 68 6f 64 3d 69 6e 73 69 64 65      p&method=inside

        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">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:

also referenced from here:

basically you have to Base 64 encode the authorization yourself:

Code Select Expand

(set 'auth (append "Authorization: Basic " (base64-enc "john:secret") "rn"))
(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 rn, than post-url works as expected!!!

the working method is now:

(post-url "http://ip.addr/cli/cgi-bin/exe.pl">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-psswdrn" ) !!



thanks again,

Robert
