Search

[cfra]

Code Version

1.1.5

Expected Behavior

Looking at thiss-js example configs, it seems like pyFF should provide a search functionality at the following url: http://pyff/api/search?q=needle.

Current Behavior

Instead, a 500 error is generated instead:

Steps to Reproduce

Not sure what information I can provide. I am using the following pipeline configuration, maybe I made a mistake there:

- when update:
    - load:
        - "http://www.aai.dfn.de/fileadmin/metadata/dfn-aai-test-metadata.xml dfn-aai.pem"
        - "http://www.aai.dfn.de/fileadmin/metadata/dfn-aai-basic-metadata.xml dfn-aai.pem"
        - "http://www.aai.dfn.de/fileadmin/metadata/dfn-aai-edugain+idp-metadata.xml dfn-aai.pem"
    - break
- when request:
    - select
    - pipe:
        - when accept application/xml:
             - xslt:
                 stylesheet: tidy.xsl
             - first
             - finalize:
                cacheDuration: PT10D
                validUntil: PT5H
             - sign:
                 key: default.key
                 cert: default.crt
             - emit application/xml
             - break
        - when accept application/json:
             - xslt:
                 stylesheet: discojson.xsl
             - emit application/json:
             - break

[leifj]

Can you try it with the discojson pipeline (builtin) instead of using a stylesheet?

[cfra]

Sorry if this is a stupid question, but how can I make the docker image run the discojson pipeline?

[leifj]

You replace the - xslt: stylesheet: discojson.xsl with just - discojson in that pipeline

[cfra]

I have updated the pipeline to look like this:

- when update:
    - load:
        - "http://www.aai.dfn.de/fileadmin/metadata/dfn-aai-test-metadata.xml dfn-aai.pem"
        - "http://www.aai.dfn.de/fileadmin/metadata/dfn-aai-basic-metadata.xml dfn-aai.pem"
        - "http://www.aai.dfn.de/fileadmin/metadata/dfn-aai-edugain+idp-metadata.xml dfn-aai.pem"
    - break
- when request:
    - select
    - pipe:
        - when accept application/xml:
             - xslt:
                 stylesheet: tidy.xsl
             - first
             - finalize:
                cacheDuration: PT10D
                validUntil: PT5H
             - sign:
                 key: default.key
                 cert: default.crt
             - emit application/xml
             - break
        - when accept application/json:
             - discojson
             - emit application/json:
             - break

The error for a get request with accept application/json to http://pyff/api/search?q=Test still looks similar to me:

what client are you using here? curl? Can you send me the cmdline you use? Also - are you using docker, which docker-container are you using ?

[cfra]

While I was using the Firefox extension Rester earlier, I can reproduce the issue with curl and the following command line: curl -H "Accept: application/json" 'http://pyff/api/search?q=Test'

I am running the docker image docker.sunet.se/pyff:stable@sha256:21acef59fa2fe2f625894fb100f7a69b5d33d8cb0f6c62bbfa018c57b3911093.

Can you try to build that docker image yourself from github.com/sunet/docker-pyff - I'm not sure if we maintain the stable tag.

[fredrikdomeij]

I have built the docker image myself. I still get the same error:

  File "/usr/local/lib/python3.9/dist-packages/pyff/mdx.py", line 432, in __getitem__
    return cptools.accept(item, debug=True)
  File "/usr/local/lib/python3.9/dist-packages/cherrypy/lib/cptools.py", line 570, in accept
    if element.value in media:

This does though seem to have to do with the Accept header handling, the following pipeline does not have this problem:

- when update:
    - load:
        - http://mds.edugain.org
    - break
- when request:
    - select
    - pipe:
      - discojson
      - emit application/json:

It just always returns json. I do still have problem with the /api/search?q=xxx url that is claimed to work (see SEARCH_URL at https://pyff.readthedocs.io/en/latest/usage/deploying.html). What is working however is /search?query=xxx, but thiss-js is using q=xxx as query parameter, not query=xxx. Trying to read the pyFF code I see

src/pyff/api.py:
    match = request.params.get('q', request.params.get('query', None))

But I cannot tell how that affects the q/query issue above.

I suggest there is some bug regarding the "when accept" handling, and that "q" should be an alias for "query" (or the other way around).

[fredrikdomeij]

Works when running pyFF 2.0.0!
