Web Service Consuming REST API with token

[Jerry Tilsley]

Anyone out there using the Cloverleaf Web Services module to consume Web REST API’s that require the use of an authentication token?

I have the connection working using TclCurl, but want to move this to the native protocols of Cloverleaf.  I know I need to override the header values, but have not been successful in getting this to work.  Any help or pointers would be greatly appreciated.

Thanks,

Jerry

Hi Jerry,

   With some help from Infor, here is a sample of what I’m using to call the Global Monitor Webservice.

Code:

catch { curl::transfer -url https://intenggmapp01.corp.ad.sentara.com/gmx/rest/views/hci
-verbose 1
-errorbuffer strCurlError
-sslverifypeer 0
-httpheader [list “Authentication: basic [encode :]” “User-Agent: AppName:Interface Engine” “Accept: application/json”]
-bodyvar ::strBody
-headervar ::strHeader
-cookiejar [file join $::HciSiteDir jmcookie.txt]
} strResult

In my case the first call logged in and setup the cookiejar. The encoding of the username and password was a GM requirement.  

Code:

catch { curl::transfer -url https://intenggmapp01.corp.ad.sentara.com/gmx/rest/view/33
-verbose 1
-errorbuffer strCurlError
-httpheader [list “User-Agent: AppName:Interface Engine” “Accept: application/json”]
-sslverifypeer 0
-bodyvar ::strBody
-cookiefile [file join $::HciSiteDir jmcookie.txt]
} strResult

All calls after use the cookie file to pass the authenticated session info.

Code:

catch { curl::transfer -url https://intenggmapp01.corp.ad.sentara.com/gmx/rest/session
-verbose 1
-errorbuffer strCurlError
-httpheader [list “User-Agent: AppName:Interface Engine” “Accept: application/json”]
-sslverifypeer 0
-customrequest DELETE
-cookiefile [file join $::HciSiteDir jmcookie.txt]
} strResult

This final call deletes the session and logs you out.  This part will be webservice dependent.

Hopefully, this helps.

I really should not answer things without coffee.  I see you already have it working with tclcurl.  Sorry, I have not tried it with webservices addon, yet.

Thanks John for the reply.  I think for the token piece I will have to go to the tclCurl route, but time will tell.
