Was asked how to access web services/website from mainframes?
I mentioned about accessing using z/OS connect for webservices but interviewer was interested to know other avenues. I searched forum and tried executing some REXX to get to a webservice/website but no success.
Accessing web
| Code: |
cmd = "curl -k https://jsonplaceholder.typicode.com/posts/1 2>/dev/null"
address USS
"USSCMD COMMAND('"cmd"') STEM(RESPONSE)"
if RESPONSE.0 > 0 then do
do i = 1 to RESPONSE.0
say " " RESPONSE.i
end
end
|
response is below,
| Code: |
response:
4 *-* "USSCMD COMMAND('"cmd"') STEM(RESPONSE)"
+++ RC(-3) +++
|
Connect to website
| Code: |
===> Scroll ===> CSR
/* rexx */
/*Make a connection to an http server, read the result and exit. */
Host = 'www.ibm.com'
Port = '8080'
srv = Socket('Initialize', 'httpd')
srv= Socket('Socket')
parse var srv src sockid
srv = Socket('Ioctl',sockid,'FIONBIO','OFF' )
srv = Socket('Gethostbyname',Host)
parse var srv src hostip
srv = Socket('Setsockopt',sockid,'SOL_SOCKET','SO_REUSEADDR','ON')
srv = Socket('Setsockopt',sockid,'SOL_SOCKET','SO_LINGER','OFF')
srv = Socket('Setsockopt',sockid,'SOL_SOCKET','TCP_NODELAY','OFF')
srv = Socket('Connect',sockid,'AF_INET' Port hostip)
parse var srv src .
If src > 0
then do
Say 'Unable to connect to' host':'port
Say 'Socket connect error:' srv
exit src
End
Exit 0
|
response
| Code: |
Unable to connect to [url=https://your_URL.com]www.ibm.com:8080[/url]
Socket connect error: 60 ETIMEDOUT Connection timed out
|
Any constructive feedback is welcome! |

| If you are trying to get your code to work... can you manually PING those sites? That is, try to make sure it is a network problem, rather than a rexx problem. |

By ping you mean from command prompt or from Mainframe.
Does
| Code: |
| TSO PING wwwdotwebsitedotcom |
work? |
