I am getting a strange result when using HTTP_req
0136.00 dcl-s RESULTS varchar(1600000) ;
0436.00 rc = http_req( 'POST'
0437.00 :'https://wwwcie.ups.com/security/v1/oauth/token'
0438.00 : *omit
0439.00 : resultS // String to receive the results
0440.00 : *omit
0441.00 : 'grant_type=client_credentials'
0442.00 : 'application/x-www-form-urlencoded');

When i look at the string results and compare it to the data that came back into my log on the ifs. The results string is shorter than the string I see in the log file. The field , results only is 1021 where the field in the log is 1481. The log shows I am successful in obtaining the token.

How did you come to the conclusion that you've only received 1021?

The ILE Debugger in the operating system will, by default, only show 1024 characters. I could see how you might confuse that for only receiving 1021 (with a slight miscount) characters. Could that be what you're seeing?

The only other thing I can think to check is the size of your variable.

[Bruceg]

Thank you for your quick response. I have been programming for a long time but was unaware of the ILE debugger constraint of 1024 characters.

961 'y5FB8F9kUT7SL-9dCJUmLbqXzyOa_hFa6-w4JtdegUTB1rdjFUe7592vQeNz'
1021 'G0xd'

Up until this spot (1024) the token is correct. My result field size is large enough to hold the token value.

Thank you once again for your help

[Scott Klement]

As far as I can tell there isn't a problem, here.

If you want to see the whole string in the green-screen debugger, you can type this at the debuggger's command line:

Code: Select all

eval MY-VARIABLE:C 1483

That will show 1483 bytes of the variable. (Keep in mind that a VARCHAR variable starts with either 2 or 4 bytes for the length of the data)

[Bruceg]

My initial issue obtaining the token seems to have been resolved. I modified example 16 to get tracking information from UPS using the token rather than license, userid/ and password. I am now getting the following error: It looks like the program may not be reading the post correctly. If anyone has some input I sure would appreciate it.

Thanks

Broken pipe means its trying to send more data after the network has disconnected.

Most likely, this is a network error not a programming error. Why are you getting disconnected?

I did rerun my request this morning and received a different message.

[Scott Klement]

You are receiving the error "bad request", which indicates something is wrong with what you're sending.

From what you posted here, your document isn't valid XML. There are stray < characters at the end of some of the lines.

Keep in mind, though, that I can only really help you with HTTPAPI. I can't help you with specific APIs... I'd have to research them and learn them to help. I can offer you consulting services if you'd like that sort of help, but assuming your plan is to do it yourself, you'll need to learn what the API requires and troubleshoot problems.
