Create a file message from a URL

OpenIM uni-app / uni-app x SDK guide for Create a file message from a URL.

Use createFileMessageByURL() with metadata from a file that is already uploaded.

Parameters

Parameter	Type	Description
`filePath`	`string` or `null`	Local name or business path; use an empty string when only a remote resource exists.
`fileName`	`string` or `null`	Display filename.
`uuid`	`string` or `null`	Unique resource identifier.
`sourceUrl`	`string` or `null`	Accessible URL of the uploaded file.
`fileSize`	`number` or `null`	File size in bytes.

import { createFileMessageByURL } from '@/uni_modules/unix-openim-sdk'

const message = await createFileMessageByURL({
  filePath: '',
  fileName: 'report.pdf',
  uuid: createBusinessUUID(),
  sourceUrl: uploaded.url,
  fileSize: uploaded.size,
})

Use real upload-result URL, name, UUID, and size values. The URL must be accessible to recipients without exposing private storage credentials. OpenIMFileElem does not contain the Wasm fileType field.

The Promise creates OpenIMMessageItem | null. Because the resource is already uploaded, send it with sendMessageNotOss().
