library-conga's Issues

HTTPCommand stopped working with headers as nested vector

Persistent Connection

Allow for using a persistent connection
Maybe something like
c←⎕NEW HttpCommand
c.Persist←1

Code cannot NOT produce warnings

Have a look at:

library-conga/HttpUtils.dyalog

Lines 293 to 297 in 3113aea

 :If 1=|≡args 

 (h b)←U.(CRLF,CRLF)U.splitFirst args 

 CongaHttpHeader h 

 CongaHttpBody b 

 _Type←''

CongaHttpHeader wants Type to be ''.

library-conga/HttpUtils.dyalog

Lines 145 to 150 in 3113aea

  ∇ {r}←CongaHttpHeader hdr;line;header;chunked;contentLength 

 ⍝ add the data from Conga's HTTPHeader event 

 :Access public 

 :If _Type≢'' 

 ⎕←'Message type expected to be "", but is actually "',(_Type),'"' 

 :EndIf

But on the next line CongaHttpBody wants Type not to be 'Conga'.

library-conga/HttpUtils.dyalog

Lines 172 to 177 in 3113aea

  ∇ {r}←CongaHttpBody bod 

 ⍝ add the data from Conga's HTTPBody event 

 :Access public 

 :If _Type≢'Conga' 

 ⎕←'Message type expected to be "Conga", but is actually "',(_Type),'"' 

 :EndIf

How can that be?

Duplicate cookie names

May have a conflict with cookies with same name, especially if they come in in trailer when chunked

HttpCommand - Initialize headers better

Currently you need to do an n×2⍴ of the header argument. Should be able to specify ('name' 'value') or (('name1' 'value1')('name2' 'value2'))

HttpCommand listener

Allow HttpCommand to maintain a "listening" loop for streamed data (e.g. Twitter feed)

HttpCommand is now in Dyalog/HttpCommand: remove from here having added tag so earlier installation images continue to use this HttpCommand

See mantis 20038.

Need to add a tag ("Pre-19.0") and then point all versions before 19.0 to this tag).
- need to alter all pre-19.0 svn externals to use this tag
Need to remove all HttpComand-related files from this repo, and update README.md

FormData in GET?

Isn't FormData always empty when processing a GET?

library-conga/HttpUtils.dyalog

Lines 335 to 339 in 3113aea

 args←QueryData 

 :If 'GET'≡U.uc Command ⍝ GET method - all data is passed in querystring 

 args⍪←FormData 

 :EndIf 

 params←(0∊⍴args)↓'?',U.UrlEncode args

HttpCommand - Cookies on redirect

Cookies should be forwarded (if applicable) on a redirection

HttpCommand.Get does not work in runtimes if not in Dyalog directory

this is because it needs ws/conga.dws in the current directory where the .exe is

Create a WS with this ⎕LX function lx:

'f'⎕WC'form'
:Trap 0
r←HttpCommand.Get'www.dyalog.com'
'f.e'⎕WC'edit'('text'r.Data)
:Else
'f'⎕WS'bcol' 200 0 0

:EndTrap
⎕DQ'.'

⎕OFF

make a new directory.

copy dyalogrt.exe to it

nothing shows in the edit field until you make a ws subdirectory with conga.dws in it.

Development versions work because they have access to development registry and environment values.
