vs
func GetHtmlFromUrl(websiteUrl string, timeoutValue int) (string, error) {
timeout := time.Duration(timeoutValue) * time.Second
client := http.Client{
Timeout: timeout,
}
resp, err := client.Get(websiteUrl)
if err == nil {
reader := resp.Body
defer reader.Close()
body, err := ioutil.ReadAll(reader)
if err == nil {
return string(body), nil
}
}
return "", err
}
My question is why I need to add a comma at the the end like this, I was thinking that comma is useless in other language i.e. c#, it seems that my vi editor enforce me to do that, I guess the golang compiler might report error if I missed the comma
client := http.Client{
Timeout: timeout,
}
Any comments? :loveliness:
build environment
