Plugin Http client Error 404

[jcompagner]

very weird, as far as i see that is then what we send
then we must be able to reproduce it (so we need to be able todo exactly what you do )

or enable what i said above:

<Logger name="org.apache.hc.client5.http.wire" level="DEBUG">
</Logger>

to the log4j.xml fil

so we have all the output of the wire what is being send

[jcompagner]

thats not really enough, we need a lot more, like the portion of the request where you see all the headers and son.
that part only seems the response

[JuanMartin]

No there are nay more about this in servoy_log.txt

I created a demo server of Prestashop for you.

No there are nothing in it, I only create some categories for try to read

This is the url for read all categories

https://TS77M53GHATMHUP5Y5F4PSFI1YVFT24 ... ategories/?

This url works in Postman

Try to read the same url on developer

cliHttp =plugins.http.createNewHttpClient();
var getRequest = cliHttp.createGetRequest(url);
response=getRequest.executeRequest();

[jcompagner]

this works fine:

var url = "https://idealjoyeros.es/api/categories/"
var cliHttp =plugins.http.createNewHttpClient();
var getRequest = cliHttp.createGetRequest(url);
getRequest.usePreemptiveAuthentication(true);
var response=getRequest.executeRequest("TS77M53GHATMHUP5Y5F4PSFI1YVFT24A", "a");
application.output(response.getResponseBody())

the problem is i guess http client 5 doesnt support those urls with the username directly in the name.
also it doesn't support empty passwords i think, so thats why i just paste in "a"

then i get the response just fine,

[JuanMartin]

Ok, now works all but there are errors with upload image:

https://idealjoyeros.es/api/images/products/30"
cliHttp = plugins.http.createNewHttpClient();
var postRequest = cliHttp.createPostRequest(url);
postRequest.addHeader('enctype', 'multipart/form-data');
postRequest.addHeader('method', 'POST');
postRequest.addParameter('Content-Disposition', 'form-data;name="image"');
postRequest.addParameter('Content-Type', content);
postRequest.addFile('image', tempFile);
postRequest.usePreemptiveAuthentication(true);
postRequest.forceMultipart(true);
response = postRequest.executeRequest(_sa.presta_clientes ,"a");
result = utils.stringReplace(response.getResponseBody(), "><", ">\n<");

response.getResponseBody is:

<?xml version="1.0" encoding="UTF-8"?>
<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">
<errors>
<error>
<code>
<![CDATA[76]]>
</code>
<message>
<![CDATA[Please set an "image" parameter with image data for value]]>
</message>
</error>
</errors>
</prestashop>

[lvostinar]

I managed to reproduce the post error and looking into it, see https://support.servoy.com/browse/SVY-17814

[lvostinar]

If I try the sample above I get the same error in older Servoy releases, are you sure this code used to work? I think the server has some problem with the image validation , but not sure how to fix it. See https://www.prestashop.com/forums/topic ... oad-photo/ for someone that had the same issue ? So, I think this is not a Servoy bug, is just that we don't set something as they expect? Maybe you can find a clue on their forum ?

[JuanMartin]

With Servoy version 22.06 this code works fine:

var url = 'https://webservice_id@domain/api/images/products/30;

cliHttp = plugins.http.createNewHttpClient();
cliHttp.setTimeout(50000);
var postRequest = cliHttp.createPostRequest(url);
postRequest.addHeader('enctype', 'multipart/form-data');
postRequest.addHeader('method', 'POST');
postRequest.addParameter('Content-Disposition', 'form-data;name="image"');
postRequest.addParameter('Content-Type', content);
postRequest.addFile('image', tempFile);
response = postRequest.executeRequest();

I don't know exactly what is changing internally in the http protocol, but there is something different that affects this process

[jcompagner]

i attached the latest http jar that has some multiplart fixes to set in http/1 mode the right content-length

now it works for you example if you use http instead of https

IF you use https then the new http client will use (because the server replies like that) http/2 mode.

The thing is in http/2 mode the content-length header is optional, and the apache http client doesn't set that then anymore.

And that server can't handle that, it finds that content-length header a mandatory thing to have (you get that give image param if you don't have that set)
but http/2 spec states its not needed anymore so or that server should not say it supports http/2 or it should work correctly in http/2 and not bother about that length being set or not.

[JuanMartin]

Great, works perfectly

Thanks a lot

[jcompagner]

but it only works in http mode not https mode to that server
and you are sending over credentials so you should be using https
but that will then map on http/2 and then you will get the same warning about "image" not there even if we are sending the exact same thing over (except not setting the content-length header)

[JuanMartin]

If I pass the url as http://webservive............
instead of https://webservice.......
It is sending it to me correctly

[jcompagner]

yes thats what i told you and that is a problem!
you should be uing httpS !
because you are also using basic authentication! so that user information. that should never be transmitted over plain http...


The server should work in httpS (http/2) mode correctly, they need to fix that.

[JuanMartin]

It is something that Prestashop itself manages.
I can only activate or deactivate https on the web and activate or deactivate the webservice.
I can't manage anything else
