CSVProducer returns error 'data type must be byte array' #263
Description
Hello,
I want to use CSV producer in the response to get data in CSV format. My swagger specification is the following
swagger: '2.0'
info:
version: 1.0.0
description: Provides an API for response in CSV format
title: Foo example
license:
name: Apache 2.0
url: http://www.apache.org/licenses/LICENSE-2.0.html
host:
localhost:8080
basePath: "/"
paths:
/:
get:
summary: Produces an response with data in CSV format
description: Produces an response with data in CSV format
tags:
- Query
produces:
- "text/csv"
consumes:
- "application/json"
operationId: getCSVResponse
responses:
200:
description: "OK"
schema:
type: string
$ref: "#/definitions/GetCSVFileResponse"
headers:
Content-Disposition:
type: string
description: "Attachment; filename=example.csv"
definitions:
GetCSVFileResponse:
description: CSV file response
type: string
format: binary
x-go-mimetype: text/csv
x-go-fileName: example.csv
x-nullable: false
Then I generate code with the swagger v0.30.4 utility:
swagger \
generate server \
--target=internal/app/rest \
-f api/app.swagger.yml
The generated GetCSVResponseOK struct has payload of models.GetCSVFileResponse type which is io.ReadCloser:
/*
GetCSVResponseOK OK
swagger:response getCSVResponseOK
*/
type GetCSVResponseOK struct {
/*Attachment; filename=example.csv
*/
ContentDisposition string `json:"Content-Disposition"`
/*
In: Body
*/
Payload models.GetCSVFileResponse `json:"body,omitempty"`
}
When I try to run my code the CSV producer fails making type cast from this type to a byte slice and returns an error 'data type must be byte array' at the line https://github.com/go-openapi/runtime/blob/master/csv.go#L60
Also I've tried type 'string' in swagger specification only:
/:
get:
summary: Produces an response with data in CSV format
description: Produces an response with data in CSV format
tags:
- Query
produces:
- "text/csv"
operationId: getCSVResponse
responses:
200:
description: "OK"
schema:
type: string
headers:
Content-Disposition:
type: string
description: A header specifying the file name
This case the generated GetCSVResponseOK struct has payload of string type but type cast into the CSV producer fails the same way.
Please tell how to write a swagger specification to get a byte slice type as a response or to convert other types into a byte slice before calling CSV producer?
