วิธีการนั้นไม่ยากเลย เพียงแค่ส่งเป็น []byte กลับไป พร้อมกับกำหนด Content-Type เป็น application/pdf ก็ได้แล้ว โดยในตัวอย่างจะใช้ fiber

func main() {
	app := fiber.New()

	app.Get("/", func(c *fiber.Ctx) error {
		c.Set(fiber.HeaderContentType, fiber.MIMETextHTML)
		tmpl := `<a href="/file">View PDF</a>`
		return c.SendString(tmpl)
	})

	app.Get("/file", func(c *fiber.Ctx) error {
		dec, err := base64.StdEncoding.DecodeString(b64)
		if err != nil {
			return err
		}
		c.Set("Content-Type", "application/pdf")
		return c.Send(dec)
	})

	app.Listen(":3000")
}

ลองรันโค้ดดู

Home

เมื่อกดที่ View PDF จะเห็นว่า Browser นั้นเปิดไฟล์ PDF ของเราให้เลย

View

แต่ถ้าหาก เราต้องการให้ browser ดาวน์โหลดไฟล์แทน เพียงแค่เพิ่มระบุ Response Header Content-Disposition เพิ่มเข้าไปแบบนี้

func main() {
	app := fiber.New()

	app.Get("/", func(c *fiber.Ctx) error {
		c.Set(fiber.HeaderContentType, fiber.MIMETextHTML)
		tmpl := `<a href="/file">View PDF</a>
		<br><br>
		<a href="/download">Download PDF</a>`
		return c.SendString(tmpl)
	})

	app.Get("/download", func(c *fiber.Ctx) error {
		dec, err := base64.StdEncoding.DecodeString(b64)
		if err != nil {
			return err
		}

		c.Set("Content-Disposition", `attachment; filename="mypdf.pdf"`)
		c.Set("Content-Type", "application/pdf")
		return c.Send(dec)
	})

	// ...
}

เมื่อลองรันโค้ดดู เมื่อกด Download PDF ตัว browser จะทำการดาวน์โหลดให้แล้ว

ซึ่งวิธีการนี้สามารถใช้ได้กับไฟล์ชนิดอื่นๆ ได้อีกด้วยนะ
