Hello GoLang World!
This is my very first post. { (I am sure more to come 
) }
Following a video tutorial, I typed in my code, but getting two errors so far can’t figure out how or what is needed to resolve those two errors.
Using Visual Studio Code on windows 10.
1= .\main.go:25:4: undefined: log
collector.OnHTML(".factList li", func(element *colly.HTMLElement){
factID, err := strconv.Atoi(element.Attr(“id”))
if err != nil {
log.Println(“Could not get id”)
2= .\main.go:31:8: undefined: factId
factDesc := element.Text
fact := Fact{
ID: factId,
Description: factDesc,
}
Here is the complete lines of code
package main
import (
"github.com/gocolly/colly"
"strconv"
"fmt"
)
type Fact struct {
ID int `json:"id"`
Description string `json:"description"`
}
func main() {
allFacts := make([]Fact, 0)
collector := colly.NewCollector(
colly.AllowedDomains("factretriever.com", "www.factretreiver.com"),
)
collector.OnHTML(".factList li", func(element *colly.HTMLElement){
factID, err := strconv.Atoi(element.Attr("id"))
if err != nil {
log.Println("Could not get id")
}
factDesc := element.Text
fact := Fact{
ID: factId,
Description: factDesc,
}
allFacts = append(allFacts, fact)
})
collector.OnRequest(func(request *colly.Request) {
fmt.Println("Visiting: ", request.URL.String())
})
collector.Visit("https://www.factretriever.com/rhino-facts")
}
