file

file({| name: String, path: String, mime?: String, fileName?: String |})

Creates a MultipartPart data structure from a resource file.

This version of the file function accepts arguments as an array of objects that use the parameter names as keys, for example:

Multipart::file({ name: "myFile", path: "myClients.json", mime: "application/json", fileName: "partMyClients.json"})txt

Parameters

Name Description

Name	Description
`opts`	Array of objects that specifies: A unique `name` (required) for the `Content-Disposition` header of the part. A `path` (required) relative to the `src/main/resources` project path for the Mule app. `mime` (optional for strings) for the mime type (for example, `application/json`) to apply to content within the part. This setting cannot be used to transform the input mime type. An optional `fileName` value for the `filename` parameter in the part’s `Content-Disposition` header.

It also specifies partMyClients.json as the value for to the filename parameter.

Source
