Content-type set to "text/plain; charset=UTF-8" for POST

[vbauer]

When POSTing to a REST API, the Content-Type is set to "text/plain; charset=UTF-8", not to "application/json".

Checked with Google Chrome and Swagger UI 1.1.3 & 1.1.4: It sends 'application/xml' as content-type - so doesn't work with REST-Endpoints only accept application/json!

Accept:application/json, text/javascript, */*; q=0.01
Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3
Accept-Encoding:gzip,deflate,sdch
Accept-Language:de-DE,de;q=0.8,en-US;q=0.6,en;q=0.4
Connection:keep-alive
Content-Length:165
Content-Type:application/xml

With Swagger UI 1.1.2 it is also not working. "Content-Type:application/x-www-form-urlencoded; charset=UTF-8" is set for the response header.

Workaround: Add a manual request header in the index.html

supportHeaderParams: true,
headers: { "Content-Type": "application/json; charset=UTF-8" },

[vbauer]

Hmm.. I checked on last snapshot and it doesn't work. But!
Workaround works perfect! Thank you very much!!

I think the lines (1515-1517) in swagger-ui.js (1.1.5) are responsible for this bug:

if (isFileUpload) {
     obj.contentType = false;
}

Source: OperationView.coffee Line: 126

obj.contentType = false if isFileUpload

[facultymatt]

Im getting this same bug in Chrome, applications/xml

[steveturner]

Experiencing this too: isFileUpload = $('input[type~="file"]').size != 0 does not seem to work properly in Chrome 23.0.1271.91

[fehguy]

I think a couple different issues are being described here.

@vbauer @facultymatt you're saying that POST is not setting the right content type? Can you please confirm you have POST enabled, as described here: https://github.com/wordnik/swagger-ui#http-methods-and-api-invocation

@lradziwonowicz is this check only affecting file uploads?

[fehguy]

addressed the default content-type in version 1.1.7, please reopen if you still see issues.

[chrisware]

Still seems to be present in 1.1.7.

Calling size() as a method fixes the problem:

isFileUpload = $('input[type~="file"]').size() !== 0;

[fehguy]

Hi @chrisware, I just updated the README--it was pointing to downloads in github, which have been deprecated. The latest version is in the dist folder of the repo. Please try with that, and it should work as-is.

[mayorbyrne]

@fehguy to avoid confusion, you might want to push those dist folder changes across the board. I'm not sure where more old files are hiding, but I had a horrible time with POST requests using the serverless version (https://github.com/wordnik/swagger-core/tree/master/samples/no-server) until i stumbled across this issue and updated the files with the ones in the dist folder.

[kamil-kielczewski]

I use this

• consumes={"multipart/form-data"},
  

• produces={"text/plain, application/json"},

Have you changed the mode is set to no-cors then it changes the Content-type then Content-type filed become immutable
in case you are using node js (express) server

var cors = require('cors')
app.use(cors())
``` then request from local host will go through
and do not use `mode` in  request header
