Relative URL when sending data

Hello,

I noticed this question has been posted multiple times before, but since
it's been some years I want to check if there are at least workarounds now.

I'm using the latest version of Orbeon (2017.2) and it's deployed in it's
own http server (tomcat), and the application that embeds the forms is at a
different url/port.

I want the embedding application to deal with data storage and processing
and so I defined this in properties-local-prod.xml

<property as="xs:string" name="oxf.fr.detail.process.send.orbeon.test-form">
        send(uri = "http://localhost/localPoint", method="POST",
data-format-version="xml", prune="false")
        then navigate("/success")
        recover navigate("/failure")
</property>

And this works - my application receives the xml data and is free to process
it.

The problem is that there could be multiple applications that use the same
form deployed at different urls.


Is there any way to make Orbeon send the data to a relative URL (like
"/localPoint"), the same way it's done with navigate ?

Hi Catalin,

I am not sure to follow: you're saying that you'd like `send(uri =
"/localPoint")` to make a query to `http://localhost/localPoint`, but then
what would the downside of using `http://localhost/localPoint` instead of
`/localPoint` in the `send()`?

Hi Alessandro,

I am running everything locally just as a proof of concept.

Let's assume there are two instances of the same web server, each with their
own domain - http://foo-dev.com and http://foo-qa.com and the Orbeon
instance is deployed at http://bar.com

Both my applications will embed the same form but the send action can be
configured to send the data to only one server.
`send()` with a relative URL would send the data to the embedding
application, rather than a hardcoded URL.

Alessandro,

As per this ticket -
http://discuss.orbeon.com/relative-URL-with-POST-td45314.html I tried
defining a new `xf:submission` node in my form with
 <xf:submission id="submit-relative-url" method="post" validate="false"
nonrelevant="keep"
                           resource="/localPoint" replace="none"/>
under <xf:model> tag and under <fr:body> I added this
<xf:submit submission="submit-relative-url">
   <xf:label>Submit to relative URL</xf:label>
</xf:submit>

When I press the submit button nothing happens and this line is logged in
orbeon.log
ERROR XFormsServer  - xforms-submit-error - xf:submission for submission id:
submit-relative-url, error code received when submitting instance: 404

If I put in the entire URL it works.

I should mention the web server that processes form data is running at port
80 and the Orbeon server is running at port 8081.

Hi Catalin,

Got it, and thank you for the additional information. If you're using an
`<xf:submission>`, you can use `f:url-norewrite="true"`. You can find more
about this on:

https://doc.orbeon.com/xforms/submission-extensions.html#context-resolution

You'll let me know if this works for you.

Hi Alex,

I tried your solution by adding
xmlns:f="http://orbeon.org/oxf/xml/formatting" schema and modifying
submission as such

<xf:submission id="submit-relative-url" method="post" validate="false"
nonrelevant="keep"
    resource="/localPoint"
    replace="none"
    f:url-norewrite="true"/>

and I get the same issue as without the attribute with the same log error.

The documentation says the attribute allows resolving resources from other
web applications in the same servlet container, but I'm using 2 different
servlet containers for my setup.

Is there anything else I can try ?


Thank you,
Catalin

Hi Catalin,

Got it, and I am not surprised that this is the way it is working. Keep in
mind that your submission is made by Orbeon Forms, not the browser. If you
have a single instance of Orbeon Forms and you need it to make queries to
different servers depending on the situation, you could make this more
explicit by having your reserve proxy (either the dev proxy or qa proxy) set
a header containing the host name to use, and in your  `xf:submission` use
`resource="http://{xxf:get-request-header('service-host')}/localPoint"`.
Would something along those lines work for you?

Hi Alex,

That sounds like a great idea.
I've been having trouble using it locally though. No matter what header key
I put in it results in an empty string.

I tried using this function in 2 different places:

1. In properties-local-prod.xml I added
xmlns:xxf="http://orbeon.org/oxf/xml/xforms" namespace and
        <property as="xs:string"
name="oxf.fr.detail.process.send.orbeon.test-form">
                send(uri = "http://{xxf:get-request-header('origin')}/localPoint",
method="POST", data-format-version="xml", prune="false")
                then navigate("/success")
                recover navigate("/failure")
        </property>
And I get this line in logs

ERROR XFormsServer  - xforms-submit-error - URI does not specify a valid
host name:
http:///localPoint?document=6be3f149f1878053609301c4eef4f9b64e2d9512&process=5f3a0cb9ed4c6c8449cf05f622ac9672c49a466d&data-format-version=xml&language=en&valid=true&app=orbeon&form-version=1&form=test-form


2. xf:submission in form source
<xf:submission id="submit-relative-url" method="post" validate="false"
nonrelevant="keep"
  resource="http://{xxf:get-request-header('Origin')}/localPoint"
  replace="none"
  f:url-norewrite="true"/>
And I get this in the logs
ERROR XFormsServer  - xforms-submit-error - URI does not specify a valid
host name: http:///localPoint


I should mention I tried to get multiple common header values, including
content-length, user-agent - both uppercase and lower case and the error
messages are always the same.
I also tried with a custom header value (added by filter on every request),
same results.

Hi Catalin,

Indeed, it sounds like `xxf:get-request-header('origin')` doesn't return
anything, in your case. Are you indeed setting that header? How are you
setting it?

Hi Alex,

I defined a new custom filter in the application that sets the custom header
to response and then chains filters. It is mapped to all URLs ("/*").

To validate it I used browser's Network tab (Chrome) to capture requests and
surely there's always a single POST request to
http://localhost/orbeon/o0/xforms-server and the custom header is set
whenever I click on the custom submit.

What concerns me is that `xxf:get-request-header()` doesn't retrieve header
values that are always set by Java or the browser (eg. Content-Length or
Origin). If it would, the error message in the log should be different. Does
it not allow getting the value for certain headers ?

Hi Catalin,

So I understand you're using a servlet filter to set the header. Are you
also setting the headers when the page with the form is loaded (not just for
the Ajax request)? I am asking because those will be the headers that will
be forwarded, not the headers Orbeon Forms received with the Ajax request.

If you're setting the headers when the form is loaded and it still isn't
working, could you instead try setting them in Chrome with the ModHeader
extension? The idea of this test would be exclude a problem with your
filter.

Hi Alex,

I set the headers with ModHeader extension and still get the same issue.

Is there anything else I could try ?

Hi Catalin,

I tried to reproduce this doing what follows:

1. Install verbatim 2017.2.
2. Put the `properties-local.xml` attached below.
3. Create a form in Form Builder, publish it.
4. In ModHeader, set the header `My-Header` to `42`.
5. Open the `/new` page, hit send. In the result, I can see the server
report it got the request parameter with value 42, which comes from the
header, as set in `properties-local.xml`.

If you try this, are you seeing something different?

Hi Alex,

With the steps provided by you and executing the submit action directly
*from the form runner* it works as expected. I can see the header value in
args field and in the url request parameter.

What's more, with the following config
        <property as="xs:string" name="oxf.fr.detail.process.send.*.*">
                send( uri = "{xxf:get-request-header('domain-origin')}", method = "post",
replace="all" )
        </property>

and domain-origin value with ModHeader set to
"http://localhost:80/localPoint", the POST request is made successfully to
the endpoint. This also works with xf:submission.


The problem is when trying to submit from the form embedded in my
application.
With "replace=all" instead of "replace=none" this time I get different
errors in orbeon.log:


2018-02-26 17:15:24,027 ERROR ProcessorImpl  - Invalid reference to captcha

After I click on send I am also redirected to
"http://localhost/orbeon//xforms-server-submit" - with error 404 because
it's not where Orbeon server is at.

Hi Catalin,

Thank you for trying this out. So it seems that embedding is part of the
problem, and why you might not be able to read the value of this header with
`xxf:get-request-header()`. What are you using to embed a form into your own
app? Are you using the Java Embedding API, or something else?

Hi Alex,

Yes, I am using the Java embedding API - the API.embedFormJava() method to
be exact.

Hi Catalin,

Got it, then I think you'll need to pass that header explicitly in the last
parameter to `API.embedFormJava()`. You'll let me know if this works for
you.

Hello Alex,

This solution works great.
I just had to set replace="none" because with it set to "all" I would get
redirected to a URL that gives error 404.

Hi Catalin,

Yes, indeed, with the embedding API, `replace="all"` isn't supported yet (as
mentioned in the "Limitations" section; see below). And I'm glad this works
for you!
