Problem Getting Connected (I think)

[emhill]

Very new to HTTPAPI and I have a JSON string I'm attempting to send and am having some issues getting connected or sending the JSON. I've run the JSON data through a verifier and it checked out ok. I also sent the string to the receiving company and they said it looked good to them.

Now here is my RPG code snippet:

Code: Select all

http_xproc(HTTP_POINT_ADDL_HEADER:    
           %paddr(add_headers));      
                                      
rc = http_post(claimurl:              
               %addr(jsonpath: *data):
               %len(jsonpath):        
               resultpath:            
               HTTP_TIMEOUT:          
               HTTP_USERAGENT:        
               'application/json');   
               
P add_headers     B                                      
D                 PI                                     
D  headers                   32767a   varying            
                                                         
D crlf            c                   x'0D25'            
                                                         
 /free                                                   
                                                         
  headers = 'client_id:' + %trim(client_id) + crlf +     
            'client_secret:' + %trim(client_sec) + crlf +
            'X-Request-ID:' + %trim(o_reqid) + crlf;     
                                                         
                                                         
P                 E                                      
 /end-free
  

This is what I get in debug:

It looks like I'm getting connected but I'm not sure what is happening after that? This is a test URL so it is not really checking credentials. Does that error mean anything to anyone?

Thanks!

[Scott Klement]

Instead of sending JSON data to the server, you're sending a path name. You need to send them the data that's in the file rather than just the name of the file!

http_post won't do this for you (and I wouldn't recommend using http_post in 2021, anyway... http_post is an old, outdated, way to do things!)

Please consider using http_stmf() or http_req().

[Scott Klement]

Based on the code you posted, here's an example of using http_stmf(). As you can see, its actually a little simpler than http_post, and I really think it'll work a lot better for you.

Code: Select all

http_xproc(HTTP_POINT_ADDL_HEADER:
           %paddr(add_headers));

monitor;
  http_stmf( 'POST'
           : claimurl
           : resultpath
           : jsonpath
           : 'application/json');
on-error;
  errorMsg = http_error();
endmon;
 

[emhill]

Just to make sure:

"claimurl" = the URL where I'm sending/receiving data
"resultpath" = the IFS path where I want the returned JSON stored
"jsonpath" = the IFS path where the JSON data to send is stored

Just making sure...

That does seem simpler. Looks like I'm going to be doing a bunch of this going forward so I'm going to get a baptism by fire.

Thanks Scott.

[emhill]

Tried the http_stmf() procedure and got nothing returned but got this in debug:

Got the message - sendraw(): entered

Then the JSON data I sent.

At the bottom of debug I got this:

(GSKit) I/O: Broken pipe.
ssl_error(406): (GSKit) I/O: Broken pipe.
SetError() #55: CommSSL_BlockWrite: send: (GSKit) I/O: Broken pipe.
http_close(): entered

Does this ring a bell?

[msddcb]

I would suggest checking the authorities on the IFS directories first.

Also check the values for resultPath and jsonPath are correct.

Broken pipe means (more or less) that you were disconnected in the middle of writing the data.

Don

[Scott Klement]

The "broken pipe" error means that you were disconnected while it was sending or receiving data.

[emhill]

We think it is a certificate issue. Getting with my network folks now.

Thanks!!!

[emhill]

When looking at the debug where it shows my JSON string, it is chopping off some characters at the end. Is there a limit to the size of the outgoing JSON? I think this came to over 177,000 characters. When I decrease the size of the string I don't get the broken pipe error anymore.

Does the http_stmf() procedure have a limit to the outgoing size? If not does anyone see anything wrong with this JSON string?:

I've not heard of a certificate causing an error like this... It could be a cipher error -- like, a bug in the cryptography is causing things to go awry, so it disconnects. ...but I can't see how it'd be a certificate? The certificate exchange happened at the start, and it was accepted...

At any rate, let us know if you figure it out.
