Post File in Swagger OpenAPI V3.0 and V2.0 examples
Today in this article, we will learn how to Post File in Swagger OpenAPI V3.0 and V2.0 examples using OpenAPI Specification or Swagger specifications.
Swagger or Open API specification provides the advantage of understanding the REST services easily (especially if developers are consuming any new API ) plus helps provide easy documentation and details of capabilities given Service/API owns.
We will cover below in today’s article,
Swagger 2.0 JSON schema – Upload/Post file

Also
- Field Name “parameters” can be defined with the below value,
"in": "formData",
"name": "file",
"type": "file"
Swagger 2.0 Upload single file
Below is OpenAPI V3.0 JSON schema definition for the image file,
{

},
"paths": {
"/WeatherForecast/UploadFile": {

}
}
}
Swagger 2.0 Upload multiple files
Below is OpenAPI V3.0 JSON schema definition for the image file,
Example
{

"info": {
"title": "TheCodeBuzz",
"version": "v1"
},
"paths": {
"/WeatherForecast/UploadFileMulti": {

OpenAPI 3.0 JSON schema – Upload/Post file
As per OpenAPI 3.0 specification files are defined as binary strings, that is,
"file": {

"format": "binary",
"nullable": true
}We will cover how to upload single or multiple files with the example of swagger/open API JSON
OpenAPI 3.0 swagger Upload single file
Below is OpenAPI V3.0 JSON schema definition for the single file,
Example
{
"openapi": "3.0.1",
"info": {
"title": "TheCodeBuzz",
"version": "v1"
},
"paths": {
"/WeatherForecast/UploadFile": {
"post": {

],
"requestBody": {
"content": {
"multipart/form-data": {
"schema": {
"type": "object",
"properties": {
"file": {
"type": "string",
"format": "binary",
"nullable": true
}
}
},
"encoding": {
"file": {

}
}
}

"description": "Success"
}
}
}
}

},
