🤗 [Question]: bodyParser nested with bracket notation #3223
Description
Question Description
Hi everyone, hope you're doing well!
I'm trying to work with some fields from a form-data request in Go, with the following example structure:
text_prompts[0][text]: "A beautiful sunset over the ocean"
text_prompts[0][weight]: 0.7
text_prompts[1][text]: "mountain range covered in snow"
text_prompts[1][weight]: -0.5
init_image: /path/to/image.jpgWhen trying to parse these values into a struct, I notice that the TextPrompts field is coming as null. I did some research and found references to other libraries in discussions here in the repository. My question is: does Fiber handle this kind of form-data request natively, or do I need to add an external library specifically for this?
Code Snippet (optional)
package main
import "github.com/gofiber/fiber/v2"
import "log"
type TextPrompt struct {
Text string `form:"text" json:"text"`
Weight float64 `form:"weight" json:"weight"`
}
type Request struct {
InitImage string `form:"init_image" json:"init_image"`
TextPrompts []TextPrompt `form:"text_prompts" json:"text_prompts"`
}
func main() {
app := fiber.New()
app.Post("/v1/generation/:engine_id/image-to-image", func(ctx *fiber.Ctx) error {
request := Request{}
if err := ctx.BodyParser(&request); err != nil {
return ctx.Status(fiber.StatusUnprocessableEntity).JSON(fiber.Map{
"code": fiber.StatusUnprocessableEntity,
"error": err.Error(),
})
}
return ctx.Status(fiber.StatusOK).JSON(fiber.Map{
"info": request,
})
})
log.Fatal(app.Listen(":3000"))
