Re: [Ftpapi] HTTP/1.1 411 Length Required with httpapi v 1.35

Scott,

Thanks for the solution, it's working now. Just posting to forum the way I'm doing, in case anyone else face this issue.

InputMessage1= '<TrackFieldRequest USERID="xxxxxxxxx"> +

<TrackID ID="yyyyyyyyyyyyy"></TrackID></TrackFieldRequest>';

httpurl = 'http://xyz.com/ShippingAPI.dll?API=TrackV2' +

'&XML=' + InputMessage1 ;

rc = http_req('POST'

: httpurl

: *omit

: ResponseMessage

: *omit

: InputMessage1

: 'application/xml') ;

Thanks,

Pargat

Pargat,

HTTPAPI needs to know whether whether to send a request body or not. The way it determines this is by whether you pass *NULL for the data or not. If you pass *NULL, it will not send a request body.

If you want it to send a request body, but you want the length of that request body to be 0, then you should pass a non-null value for the data, but pass the length=0. This will do what you want.

You may be thinking "it should just know I want a request body because I'm doing a POST (or PUT?) request". But, I don't want to hard-code a list of methods that do/don't send request bodies because I want things to be generic. People are frequently adding new methods to the HTTP protocol for special/specific purposes, and I don't want to hard-code them all into HTTPAPI. Instead, I want you to be able to specify any method, and control for yourself whether it does or doesn't have a request body. That way, when new methods are released, they'll work without any changes to HTTPAPI.

So -- it's very simple. Pass a non-null value for the post/put data, and pass length=0, and it will do what you want.

Hi Scott,

I see this issue was raised in early Feb this year and you added the fix in release 1.34. But I'm still facing same issue in version 1.35.

I see you changed line 404 as pePostDataLen >= 0 but in my case pePostData and pePostProc also shows null so it never turn on flag for wwSendReqBody and I'm getting HTTP/1.1 411 Error.

When I change flag wwSendReqBody to *ON in debug, then it works. Please advise if I can add any additional condition to handle this scenario.

0404.00 c if pePostDataLen >= 0 and

0405.00 c (pePostData<>*null or pePostProc<>*null)

0406.00 c eval wwSendReqBody = *on

0407.00 c endif

Change Log:

Changes to version 1.34 from 1.33

- If a procedure or non-null pointer is provided for "upload" data

(i.e. POST, PUT or other stream upload data) but data length=0,

then send a zero-length request body. Omitting Content-Length

on a PUT/POST request causes "411 Length Required" on some

servers. (Broken since 1.24BETA15)

Thanks,

Pargat
