Hi, I'm using wconnect 5.72 and I'm generating a post call with tokens and binary image - all parameters all together is around 366 characters long. Call doesn't work. If I use postman with exactly same parameters and file - all works well. It makes me thinking that this version of wconnect has a limit in URL length. Does anyone know if latest version has this fixed or I'm missing something ?

This is browser/client specific. Some browsers restrict the URL to 256 characters. I think that would be really old browsers - newer browsers don't balk at large URLs AFAIK.

If Postman to the same URL works, then the server is working, no?

Hmmm. The call is from desktop app - I'm not sure how browser is involved here... Server works just fine. Postman call works, http server is returning 200 OK and image is correctly transferred to the server but from desktop app I'm always getting "Invalid token". I checked many times - I'm passing valid,correct token but it's very long... Let me show the code and sample data:

I think I posted into wrong forum.... This is about a post call from desktop app, which is using stand alone wwHTTP library...

*** The browser name (User Agent) that wwHTTP sends to the server cUserAgent = "West Wind Internet Protocols 5.0" &&+ TRANSFORM(WWVERSION_NUMBER)

from wconnect.h :

DEFINE WWVERSION "Version 5.72" #DEFINE WWVERSION_NUMBER 5.72 #DEFINE WWVERSIONDATE "April 21st, 2015"

That sounds you have an issue with client code.

I just checked (this is in v7 though):

DO wconnect

loHttp = CREATEOBJECT("wwHttp")

lcUrl = "https://west-wind.com/wconnect/testpage.wwd?"  +;
        REPLICATE("10&", 300)
        
? LEN(lcUrl)

lohttp.AddPostKey("LastName",REPLICATE("20&", 400))

lcHtml =  loHttp.Post(lcUrl)
? loHttp.cErrorMsg
ShowHtml(lcHtml)

...and that works fine for me.

This sends a URL that has a 900 char querystring and that works fine. POST content can be any size (from the sending end) will depend on the server settings - there are basic limits that can be configured on the server.

If I recall there are still limits but it's somewhere closer to 2000 character I believe.

I guess you should try to figure out: Is the error coming from the client or the server. It's possible you're getting an unrelated error from the server that has nothing to do with the URL length but a generally invalid server url.s

+++ Rick ---

Yup - doing some quick tests it looks like the limit is somewhere around 2000 characters - running that code sample I can't send 700 replicates(), but 680 works - so somewhere around 2k on the URL seems about write.

In this case though it's the server that's rejecting it, not WinInet:

and that's probably configurable. This is configured in the IIS request limits I believe.

+++ Rick ---

Rick, Thanks for spending your time and checking it ! The server is Apache on Windows. Delphi client works just fine so I'm pretty sure it's on VFP app side...

I just purchased your latest Client Tools - I will try with that version. If I won't figure out can you help me with it ? I will pay your support rate no problem...

Well the sample I posted you can try yourself - that checks for the client issue and that appears to be working just fine, so I'm pretty sure it's not hte client unless you're not sending the data correctly and you're actually getting an unrelated data - perhaps related to the embedded data you are sending.

That's why I ask - is it a server exception or a client error?

And yeah I can probably help if you can't resolve this...

+++ Rick ---

I just put latest version of wwClient and now I have a different problem... Code is fired but image is not transmitted into HTTP Server and I always get empty string as a response from server.

You can't pass the file the way you are passing it.

It all depends on what format the server expects, but if it includes a binary file it's likely a multi-part form upload.
