Error 415 in Extraction endpoint

[Luca Di Natale]

Hi all,

i'm trying to retrieve the xml embed metadata from an Europass CV file.
If i upload the, let's say, "cv.pdf" on "Update your CV" from the Europass main site it correctly upload it and allows me to edit all the prepopulated fields; but when I try to pass the same pdf file ("cv.pdf") using RESTful XML Extraction endpoint i always get error 415: Unsupported Media Type. Is there something i'm missing?

I've also tried to send an XML to pdf-cv endpoint (expecting a pdf byte stream or something equivalent) but still get the same error as above

Any help would be really appreciate
Thanks
Luca

Dear Luca,

Thank you for your interest in Europass. The problems you're facing might have to do with the Content-Type header of your requests. 

In the case of the /extraction endpoint, the Content-Type header needs to be application/pdf. Here's a curl example:

curl https://europass.cedefop.europa.eu/rest/v1/document/extraction -H "Content-Type:application/pdf" --data-binary @cv.pdf -o cv.xml

While in the case of the /to/pdf-cv endpoint it needs to be application/xml:

curl https://europass.cedefop.europa.eu/rest/v1/document/to/pdf-cv -H "Content-Type:application/xml" -d @cv.xml -o cv.pdf

Please let us know whether this fixes your problem.

Best regards,

Hi Dimitris,
Thanks for your reply. I didn't mentioned that i've followed, step by step, online documentation. So i actually used application/pdf for Extraction and application/xml for The other one. I've tested your service using a REST Client, maybe i should test with another One (if u say that your tests went all OK).

Any further suggestion?
Thanks a lot in advance

Hi Luca,

I'm not sure which exactly is the "REST Client" you're referring to. Check for example in the attached screenshot how to make a successful request with Firefox's Poster add-on.

I might be able to help you more if you provide me with further details on the client you're using and how exactly you're using it (e.g. how do you upload the pdf file).

Best regards,

Dimitris

Hi Dimitris,

i'm currently using POSTMAN as a Google Chrome extension. As you can see in the attached screenshot, I still get Unsupported Media Type. My first attempts where made by a REST Client I wrote in Java. I've also tried either POSTing the cv.pdf from a form than passing it as a File, neither of them worked. 

Where I'm mistaking?

Thanks
Luca

Hi Luca,

How do you upload the pdf in postman? You'll need to select the "binary" option and upload it from your file system. Check the attached screenshot for a successful request to /extraction using postman.

Let me know if this works for you. I'll also try to send you a Java example later on.

Regards,

Dimitris

Hi again Luca,

As promised, please also find attached a Java-based example.

It's a standard Maven project which demonstrates how to consume the Europass REST API's /extraction and /to/pdf-cv endpoints (using the Unirest library as an HTTP client). You can run it via the command line as shown below:

$ mvn clean test

(It's assumed that Maven is already installed on your system)

Hope this helps.

Regards,

Dimitris

Hi Dimitris,

thanks a lot for your help, really appreciate your effort :)

POSTMAN worked. The problem was in multiform-data instead binary.
I've build your little project with maven but i'm facing connection timeout exception even if i completely remove timeout (Unirest.setTimeouts(0,0);).

I'll atteach my code (that's basically your code) and the exception thrown. 
Could you take a look in your spare time? 
Thanks man, really appreciate
Luca

Perhaps you're behind a proxy? (postman could still work if you've configured your browser accordingly)

Can you telnet europass.cedefop.europa.eu on 443?

Everything looks fine here and I can run the Java tests without any problems.
