Re: [Ftpapi] I'm obviously missing something ...

Hi Jon,

You would need to specify the content-type when sending data, which is normally done with a POST or PUT request.

Simply specify the type 'application/json' (without preceding it with "content-type:") in the appropriate parameter to http_req, http_string, http_stmf, http_post, etc...  then it'll be taken care of for you.

OK - thanks.

That explains why the suggestion Charles made on WEB400 to add  http_setAuth(HTTP_AUTH_NONE:'':''); had no impact.

Would I ever need to specify content-type?

Hi Jon,

The way you're sending the content-type will work fine with a GET call, because HTTPAPI doesn't add a content-type with GET. However, if you use the same 'addSpecialHeaders' routine with a POST request, it will list the content-type twice -- once from HTTPAPI, and a second time from your code.   Please consider using HTTPAPI's mechanism for setting the content-type rather than doing it yourself to avoid this conflict.

I haven't gotten around to checking WEB400 yet, I'll check that out now.

Thanks Scott,

I'll look at those options.

I was hoping someone would respond since I have resolved the problem but had no email to reply to!

In the end I had missed something - I had failed to notice just how huge the JWT authorization code was and defined the field too small - in the log I had done a check on what was shown but didn't check far enough down the string to notice the end had dropped off.

As to the content type - the API specification (and all their code samples) call for it so I left it in place.  In the case of all of the POST APIs this will be required so I guess for simplicity they just leave it in all the time.

Thanks for your help.

Hi Jon,

I don't know why you are getting the '401' error?  Possibly there's a problem with the Bearer token you're using?  When a login fails, the HTTP protocol typically will just re-send the 401 error.  So if you give a bad userid/password, it'll simply say '401, I need a userid/password' or if you give a bad bearer token, same thing, etc.

Its not clear why you are adding a 'content-type' here. Content-type is meant to tell the receiving system what sort of data is being sent.  In this example, you are doing a GET request, so it is not sending any sort of data (aside from the URL itself, but content-type does not relate to the URL...)

I'd also recommend switching to use the newer APIs such as http_string, http_stmf or http_req rather than the old stuff like http_get.  It really shouldn't matter for what you're doing, but as it gets more sophisticated, you'll find the old routines like http_get are difficult to use.

Cross-posted to HTTPAPI and WEB400

I just coded up a basic Zoom API request - this is the basic HTTPAPI code:

        url = 'https://api.zoom.us/v2/webinars/' +
              %EditC(webinarId: 'X') +

        headerVars.contentType   = 'application/json';

        headerVars.authorization = 'Bearer mySecrtetCodeGoesHere';

        http_xproc( HTTP_POINT_ADDL_HEADER
                  : %paddr(addSpecialHeaders)
                  : %addr(headerVars) );

        rc = http_get( url: '/tmp/result.txt' );
        if rc <> 1;

        Dcl-Proc addSpecialHeaders;
        Dcl-Pi *N;
          headersToAdd    Varchar(32767);
          vars            likeds(headerVars) const;

        Dcl-C CRLF x'0d25';

        headersToAdd = 'content-type: ' + vars.contentType + CRLF
                     + 'authorization: ' + vars.authorization + CRLF;

This gives me a "401 - This page requires a user-id & password" error

If I copy/paste the credentials and URL into Insomnia and test it - it works.  The user Id stuff is in the "secret key" bit.

Since I copied and pasted this stuff into insomnia from the RPG stuff I can only assume I missed a step somewhere. But where?
