Wie handhabe ich JSON und das Hochladen von Bildern gleichzeitig in einem Go Gin Framework?

func UpdateProfile(c *gin.Context) {
    type request struct {
        Avatar      *multipart.FileHeader `form:"avatar" binding:"required"`
        User struct {
            Username    string `json:"username" binding:"required,min=4,max=20"`
            Description string `json:"description" binding:"required,max=100"`
        } `form:"user" binding:"required"`
    }

    var updateRequest request

    // Bind the request data to the request structure
    if err := c.ShouldBindWith(&updateRequest, binding.FormMultipart); err != nil {
        // Return an appropriate error response
        _ = c.AbortWithError(http.StatusBadRequest, err)
        return
    }

    // Handle the image
    // ...

    // Handle the JSON data
    // ...
}

--boundary
Content-Disposition: form-data; name="avatar"; filename="profile.jpg"
Content-Type: image/jpeg
//... image data
--boundary
Content-Disposition: form-data; name="user"
Content-Type: application/json
{
    "username": "username",
    "description": "description"
}
--boundary--
