Re: [U2] callHTTP creating Header for Host,
More troubleshooting ... on 7.3 the code CMD.STATUS = setRequestHeader(RHANDLE,"Host",HOST.AND.PORT) adds a second entry to the host header instead of replacing it, such as: Host: www.myplace.com, www.myplace.com So I am putting in a conditional to only add the Host header for UniData 7.2, hoping that all 7.2 builds do not include it and all 7.3+ will! I'm open to better way to handle the situation :-) Thanks, Steve... -Original Message- From: regalitare To: u2-users Sent: Wed, Aug 22, 2012 9:10 pm Subject: [U2] callHTTP creating Header for Host, Greetings I am working on an issue with UniData but I suspect it possibly affects both flavors. I am making a callHTTP GET request to a server that has virtual hosts. Basically, one server on a single IP address has multiple named web sites. On UniData 7.3.0 Personal Edition on Windows I tested my code and it works fine. On UniData 7.2.10 on Windows it came up with the "default" web site (same as if I just use the IP address instead of the FQDN) instead of mine that was named in the URL. I suspected the "Host" header that is required to be sent for HTTP/1.1 protocol might be missing on UniData 7.2. So, I added this line to the code to set the header: CMD.STATUS = setRequestHeader(RHANDLE,"Host",HOST.AND.PORT) And voila! On 7.2 it started working properly! But it broke 7.3! On 7.3 it brings up the default web site if I explicitly set that header. Is this a known bug/issue? Is there something I should do to work around it now so that a UniData upgrade won't bite me? I've thought about reverting to the old socket interface but I'd like to use callHTTP if it is "stable" since it is so convenient.

Re: [U2] callHTTP creating Header (Karl-Heinz Winter)
I found the solution by myself! The problem could be, that the functions 'setRequestHeader' und addRequestParameter' are formatting the data in any way, that the webserver doesn`t understand the request. When I logged the outgoing traffic to port 80, I have seen valuemarks in the header information. On Pickwiki there is a good example of calling a web service: http://www.pickwiki.com/cgi-bin/wiki.pl?CallHTTP. The second example shows how to do a request with OPENSOCKET, WRITESOCKET and READSOCKET. These classes are posting the data without any change. I tried it and the webserver response ist OK!

Re: [U2] callHTTP creating Header
Hello Karl-Heinz, It could be that the issue is not with UniVerse, rather at the web server end. If you can share the source code with us which you are using to build up the request this may help us to trace the problem. Also, are you running UniVerse or UniData and on which OS? I would suggest turning on protocol logging which should help in locating the cause of the problem. To do this use the protocolLogging() function which requires three parameters 1. The name of the file to which you want to save the logs. 2. ON 3. 10 (level 10 should give you enough info to help you with debugging). The function returns true or false depending on whether or not logging has started successfully. Other than that, try searching the mailing list. I would bet that you are not the only one who has had this problem. Otherwise check the BASIC Extensions documentation at the Rocket website.

RE: [U2] CallHTTP vs cURL...
David, buried in my point was that you may be able to get other phantoms to be more effective, thus reducing your requirement for phantoms for other tasks. So with luck, when you do need a new one for CallHTTP your total phantom usage won't be any more than it is now. Like anything, especially in this economy, eliminate existing waste before attempting to avoid new expenses. But be careful about making your existing ports more effective. In it's strictest technical sense IBM licensing would prohibit even these sorts of optimizations - have your lawyers do lunch with their lawyers...

RE: [U2] CallHTTP vs cURL...
If only 5-6 times a day, why not just kill logoff the existing phantom, immediately after spawning a replacement immediately after the CallHTTP --> I assume new process would initialize what it needs to, and start over, so you would have an iPhantom issue for a second or 2 at most.

However i use it not to get round licencing (as this is usually from a uniobjects call anyway) but because for some reason curl is many times more efficient than callhttp. I presume the udt process has to load some library to run the callhttp, whereas the execute is just the normal *nix process spawn overhead. Anyway we did it as we had occurrences of the callhttp taking say 6 or 7 hundred milliseconds but the execute curl took 2 or 3 hundred and in a very heavily used web service (between 5 and 50 calls per second) this adds up to quite a difference. --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

Like Glen, we also use cURL for shipping rates and address validation with UPS and Fedex web services. We haven't had issues with missing data, but have with timeouts. If you don't tell cURL to time out, it will wait for a response for a very lng time. Very bad when the whole order desk is hung due to UPS or Fedex having a problem with their site. We learned that one the hard way. This is what we execute now: EXECUTE 'SH -c "curl --connect-timeout 10 --max-time 10 -d @/tmp/':REQ.ID:' -k ':URL:'"', OUT > XML.TXT The XML request is written to a sequential temp file, then deleted after the execute. The curl calls are made from user or UOJ sessions, so I can't say with certainty if there is any affect on the phantom licensing. -John --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

RE: [U2] CallHTTP vs cURL...
I utilize cURL for shipping tracking updates, among other automated tasks, that run bi-hourly. Since the data is not critical, I don't perform any connectivity or results checking. If you do decide to shell a cURL process, make sure that you verify the response is well-formed. You will need to implement the timeout switch too. Your better off putting raw data into a wrapper of some kind so that you can verify the start/end of the transaction(formation checking). I've seen cURL dump only the first 2-3 lines of an entire XML document back to me without complaining about connection errors. Timeout handling should also be done, so if your current CallHTTP code doesn't do all of that then you have some design work to do.

RE: [U2] callHTTP
Stu, I forgot to mention what you might expect back in the response and headers fields. The response will contain whatever the web service you are posting to/requesting from is programmed to respond with. In the case of a web service, for example, it will probably return an XML document. In the case of a web site it may return whatever exists at that URL eg html or possibly a zip or doc file for example. If you get something like this in your response, the http Headers should contain the mime type and other info about the document. Generally, it will then be up to you to handle and process the file with whichever tools you determine are appropriate. Generally I think most web protocols will do some form of ascii encoding (b64/uucp/etc) to ensure that the file is web safe. If you receive the file in this way then you have to uncompress/uuucp/b64 it. Otherwise, if the file is potentially binary then you need to handle it more delicately with UV as writes, for example, can munge the file. Also, the potential size of a file could be an issue.

RE: [U2] CALLHTTP....UV 10
Hi,
I think I had similar problems, but eventually got it working with this
code:
HTTP.METHOD = 'GET'
REQ.HANDLE = '' ; POST.DATA = '' ; TIME.OUT = '' ; RESP.HEADERS = '' ;
RESP.DATA = '' ; HTTP.STATUS = ''
Ret = setHTTPDefault('VERSION','1.1')
Ret = createRequest(URL,HTTP.METHOD,REQ.HANDLE)
Ret = setRequestHeader(REQ.HANDLE,'Connection','Keep-Alive')
RET.STATUS =
SubmitRequest(REQ.HANDLE,TIME.OUT,POST.DATA,RESP.HEADERS,RESP.DATA,HTTP.
STATUS)
Where RESP.DATA will contain the downloaded data
Setting the HTTP Version to 1.1 is what fixed mine to get the data to
come down, I do recall only getting headers previous to that.
Hope that helps
Peter

It's open source and free, well supported, very stable, very popular, and it's quite capable of doing HTTP post w/wo SSL as well as many other tricks.

Thanks to all who gave me tips, I got it working! I had problems with
AM's being inside my posted data as well is a wrong encoding type, once
I solved those issues it works perfect.
Thanks again

Peter,
Here are a couple of local subroutines I use for synchronizing records
to other servers using a CGI post. The corresponding CGI program on the
hosts generates a return value structured like...
SG: NUMBER.OF.ERRORS: SG: ERROR.MESSAGES
Where SG is EQUATEd to CHAR(255), ERROR.MESSAGES is an
attribute-delimited array of error messages and NUMBER.OF.ERRORS =
DCOUNT(ERROR.MESSAGES, @AM). It makes it simple to make sure we got
something legitimate back from the POST without having to interpret all
the various http status codes.
Hope this helps.

RE: [U2] CallHTTP
Our initial design was to send one transaction at a time, which works just fine. But there is a desire to send multiple transactions at one time. I was thinking along the same lines, that someone put a limit to the length UniVerse will allow for the parameters because they never imagined that someone would try to put the entire record(s) in one XML string. I think that it was designed to send one field at time.

You're right that there's no excuse for it dying like that, but I actually don't think there is a defined limit for a GET or query string. Here are some related factors. Some or none may be relevant here, but it's good to consider these things: - The length of the query string in total is generally agreed to limit at 1024 bytes, but I don't think that's a part of the spec. - There are occasionally limits on the size of the domain name, which is included in the total for the query string. - There may be no defined client side limit, but some browsers do limit their upload byte count, and that changes with releases. - Some web servers and browsers have a specific limit on the total amount of data submitted in the header parameters for any given form, whether GET or POST. This may be release-dependent. For example, (from (bad) memory) IIS4 allowed up to 2MB for headers, IIS5 brought that down to a default of 1MB (?), IIS6 even further down to 2K (?). I've seen individual utilities limit this after data comes into a web server so that the application doesn't get crashed by too much data. - Some browsers have yet another limit on the size of the FORM ACTION parameter. Since the original inquiry is dealing with CallHTTP, this isn't a browser, and since the error is coming from Universe the issue is not with the server. In this case it seems addRequestParameter has yet another limit which the authors felt reasonable, but they didn't code a nice error for anyone who tries to exceed that value. One way around this sort of thing relies on you having access to the server side of the Web Service: Code it so that data can be posted in pieces rather than megabytes at a time. One of the parameters passed to the input can be "block X of Y" and the last block sent to the Web Service should get a confirmation for all blocks in the return values.

Tony, - There are occasionally limits on the size of the domain name, which is included in the total for the query string. RFC3696 (which collates information from other RFCs) places the following limitations on a hostname from DNS: A DNS label (the parts of a domain name delimited by '.') may not be longer than 63 octets. A complete fully qualified domain name cannot be longer than 255 octets. Probably nothing to do with the CallHTTP problem, but useful to know.
