How to convert to []byte

[shehuaqigai]

Thank you very much!

Could you please be a bit more elaborate on what you are trying to do?

wordDocx, docxErr := docx.Open(docxPath)
if docxErr != nil {
ctx.StopWithStatus(500)
return
}

		replaceMap := docx.PlaceholderMap{
			"year":  "2024",
			"month": "04",
			"day":   "03",
		}
		// replace the keys with values from replaceMap
		docxErr = wordDocx.ReplaceAll(replaceMap)
		if docxErr != nil {
			ctx.StopWithStatus(500)
			return
		}
		ctx.Header("Content-Type", "application/vnd.openxmlformats-officedocument.wordprocessingml.document")
		ctx.Header("Content-Disposition", "attachment; filename=example.docx")

		ctx.Write([]byte)//iris.go  I need to type directly back to the file stream, not write to the file

Ahh, i see. Thanks for elaborating.

This should already be possible. You can use document.Write for that. Something like this should work:

// ...
out := []bytes{}
buf := bytes.NewBuffer(out)
err = wordDocx.Write(buf)

// now you can continue work with just the byte slice of the rendered document
ctx.Write(buf.Bytes())
