curl "Accept" header issue in relation to the "Response Content Type" selection

[kchsieh]

I am using v2.1.4, for some reason the "Response Content Type" does not show up with the spec below and the generated curl command is this (notice the --header 'Accept: text/html' which is strange and nowhere to be found in my spec):

curl -X GET --header 'Accept: text/html' --header 'app_id: my_id_here' --header 'app_key: my_key_here' --header 'sid: 123456' 'http://localhost:3000/student'

It doesn't appear because your 200 response doesn't state it returns anything. The issue with the curl is different.

[kchsieh]

Thanks for the tip, I have updated my swagger.json to include schema (see below) and the "Response Content Type" selection is showing up. But the generated curl header still says 'application/json', when I selected 'application/xml':
curl -X GET --header "Accept: application/json" --header "app_id: my_id_here" --header "app_key: my_key_here" --header "sid: 123456" "http://localhost:3000/student"

Updated swagger.json:

To make it more simple, I think you can delete "produces" in "student" and try it again. A "produces" on the top level is enough.

[kevprice83]

This has been tried and the same error is still produced.

[kevprice83]

Still experiencing the same problem as described above. Any update on a fix for this?

[kevprice83]

any updates on this issue?

[jlh424]

I am having the same problem, with 'Accept: text/html' showing up in the curl command even though I have not specified that anywhere.

[fehguy]

fixed in efb7765

[kchsieh]

@fehguy are you sure this has been fixed. I just downloaded the code from the dist folder (this is from master branch) and the generated curl command is fixed to "text/html" like below:

curl -X GET --header 'Accept: text/html' --header 'app_id: my_id_here' --header 'app_key: my_key_here' --header 'sid: 123456' 'http://localhost:3000/student'

[fehguy]

@kchsieh it's been extensively tested, but there's always the possibility of an issue. Can you please share the definition that is producing this?

[kchsieh]

@fehguy , thanks for the quick response. My swagger.json spec. is in my March 1st comment above.

[fehguy]

OK I just tested this and get the following:

curl -X GET --header 'Accept: application/json' --header 'app_id: my_id_here' --header 'app_key: my_key_here' --header 'sid: 123456' 'http://localhost:3000/student'

Can you please make sure you don't have a cached copy of swagger-ui.js in your browser?

This issue was originally against ef0fc16276847b22e43a1dc488e246faf20e6e8b but I've updated it to the release 2.1.15 in #2245

[fehguy]

@kchsieh please pull master / dist and retest?

[kchsieh]

@fehguy , just downloaded master/dist again and this time I tested it without put them into my Rails application (suspect it was caching somehow). But when I select 'application/xml' from the 'Response Content Type', the generated curl script still says 'application/json'. Fyi, tested using 3 different browsers and got the same issue.

[fehguy]

OK to be clear, you're now getting a different response than before?

[kchsieh]

correct, when I put it into my Rails application, select 'application/xml' or 'application/json', I always got 'text/html'.
Without test it in my Rails application, just use file:/// and test it in the browser, when I select 'application/xml', it generate 'application/json'.
